1. INTRODUCTION

Odontogenic infections have been a problem for humans for as long as they have existed. However, despite millennia of research, bacterial illnesses nonetheless persist in humans [1]. Over 90% of infections in the head and neck region are odontogenic in nature worldwide. Numerous bacterial species found in the mouth take advantage of human immunity and dental care to produce infections that can spread to the neck, face, and other parts of the body, potentially leading to significant consequences. Diverse bacteriological investigations have differing conclusions [2]. Most bacterial infections in the orofascial area typically cause either a disruption of the regular flora or the relocation of normal organisms to the site, where they are typically absent. Dental caries, periodontitis, pericoronitis, damage to the dentition and its supporting tissues, and problems from dental operations are among the predisposing factors for pyogenic odontogenic infection. Typically, the infections involve typical endogenous flora and are polymicrobial in nature. Descental mediastinitis, septic shock, upper airway obstruction, jugular vein thrombosis, venous septic embolus, carotid artery pseudoaneurysm or rupture, pleural empyema, pericarditis, and disseminated intravascular coagulopathy are among the complications associated with odontogenic orofacial infections [3]. Most commonly occurring bacteria are Streptococcus sp. (4.38%), Streptococcus milleri (3.50%), Bacteriodes melaninogenicus (3.50%), Pseudomonas aeuroginosa (3.50%), Streptococcus mutans (1.75%), Actinomyces odontolyticus (12.28%), Lactobacillus spp. (8.77%), Peptostreptococcus sp. (7.01%), E. coli (5.26%), Streptococcus sp. (4.38%), Streptococcus milleri (3.50%), E. coli (5.26%), Streptococcus sp. (3.58%), Streptococcus mutans (1.75%), and Fusobacterium nucleatum (0.877%), accordingly. The anaerobic bacteria were shown to be 100% susceptible to erythromycin (100%), cefotaxime (98.48%), and clindamycin (96.96%), but 100% resistant to amoxicillin and penicillin. The aerobic strains, on the other hand, were susceptible to amoxicillin (79.16%) and resistant to penicillin (47.91%). Therefore, the odontogenic infection cannot be effectively determined by antibiotics alone [4, 5]. In an Indian investigation, however, the most frequently isolated bacteria were Porphyromonas gingivalis (23.33%), Streptococcus aureus and Actinomycetem Comitans (6.67%), streptococci (10%), and Klebsiella pneumoniae and Streptococcus pyrogens (33.33%). High sensitivity to Gentamycin (84%), Cefotaxime (80%), Ciprofloxacin (76%), Azithromycin (76%), Cefuroxime (72%), Amoxicillin (72%), Augmentin (72%), and Penicillin (36%), were the most sensitive antibiotics according to the results. (6). The purpose of this study is to review the common bacteria that cause fascial space infection and their susceptibility to antibiotics. The literature demonstrated that the common microorganisms responsible for infections in the face space vary in frequency. This could be the result of the studies being carried out in many parts of the world, where the health care system, particularly with regard to oral health, varies greatly. Furthermore, no local investigation has been done that could assist us in identifying the common pathogen responsible for facial space infections and the local population’s pattern of antibiotic susceptibility. Therefore, the purpose of this study is to gather data for the local community so that, in the future, we may better manage and practice our procedures and administer the proper antibiotic therapy while keeping in mind the prevalence of the pathogen that causes the majority of facial space infections in the local population.

2. LITERATURE REVIEW

Research shows that odontogenic infections, which are typically brought on by dental caries, pericoronitis, periodontitis, trauma to the dentition and its supporting structures, or problems from dental operations, account for the bulk of pyogenic oro-facial infections. While most of these infections are polymicrobial in nature, a number of studies show that Streptococcus, Peptostreptococcus, Eubacterium, Porphyromonus, Prevotella, and Fusobacterium species are the most frequently isolated bacteria in odontogenic infections; more recently, Staphylococcus aureus has also been identified as an oral pathogen [7]. The most frequently reported permanent molars to be affected by pyogenic odontogenic infection are the second and third ones. Additionally, the fascial spaces to which the infection may spread may depend on the anatomic placement of the affected teeth. Several researchers have reported that other fascial spaces are more common with pyogenic odontogenic infection, despite a prior study’s finding that the submandibular space was the most commonly involved [8]. Odontogenic illnesses account for 7–12% of all antibiotic prescriptions. But the recommendations are typically empirical and don’t include regular sensitivity and culture testing. Unfortunately, extensive antibiotic use has led to a decline in the sensitivity of oral bacteria, with an increasing number of resistant strains. The choice of antimicrobial drugs for empirical therapy is significantly influenced by the emergence of antibiotic resistance [9]. Osteomyelitis, retropharyngeal spread, haematogenous dissemination with septic shock, disseminated intravascular coagulopathy, carotid artery erosion, suppurative mediastinitis, intracranial extension, cavernous sinus thrombosis, Lemierre syndrome, maxillary sinusitis, Ludwig’s angina, and airway obstruction are among the complications of pyogenic odontogenic infection that point to the potentially dangerous nature of these infections [10]. The limited susceptibility tests on oral bacterial isolates conducted in Uganda used saliva samples and throat swabs rather than specimens from pyogenic odontogenic infections. In order to treat dental abscesses, gingival infections, periodontitis, and other perioral infections, the World Health Organization’s prescription guidelines as well as the Ministry of Health of Uganda’s clinical guidelines suggest using phenoxymethylpenicillin, amoxicillin, erythromycin, metronidazole, and procaine penicillin fortified. However, no research has been conducted in Uganda to evaluate the effectiveness of the antibiotics in pyogenic odontogenic infections. Furthermore, bacterial sepsis is said to be widespread in immunodeficiency, and research have previously looked into the connection between pyogenic odontogenic infection and acquired immunodeficiency syndrome, as well as the human immunodeficiency virus [10]. The human mouth cavity is richly inhabited with microbiological life that plays a number of roles in our health and well-being, much like the skin and other mucosal surfaces. It can also become infected by invasive diseases and natural flora, much like any colonized surface. Odontogenic infections, or illnesses with a dental origin, are among the most prevalent infections globally [11]. Adult odontogenic infections are the main source of deep neck infections; these infections can migrate along fascial planes to include the face and deep neck regions. Treatment for these infections frequently involves interdisciplinary teams, including emergency medicine specialists, dentists, oral surgeons, otolaryngologists, and primary care physicians. In [12]. In the United States, nearly 90% of persons will have had dental caries by the time they are 65. Minor oral infections are also frequent. More often than women, men are infected, and individuals between the ages of 20 and 50 account for almost 70% of infections [13]. The two most frequent co-occurring diseases with odontogenic neck infections are diabetes and tobacco use. With the widespread use and availability of antibiotics over the past few decades, dental, odontogenic, and deep neck infections have decreased; however, the proportion of deep neck infections with odontogenic origin has increased and is currently the leading cause of deep neck infection in adults in the United States [14]. Despite advancements in antibiotic therapy and increases in socioeconomic standards of living, odontogenic infections remain a common cause of hospital admissions in tertiary care settings [15, 16]. Previous research has shown that the most prevalent cause of odontogenic infection is a partially erupted mandibular third molar, with the submandibular region being the typical site of involvement. The most important bacteria causing infections in these trials were Streptococcus hemolyticus, Streptococcus α hemolyticus, and Staphylococcus epidermis [17, 18]. There are twenty and thirty-two teeth in the oral cavity of children and adults, respectively, evenly distributed between the mandible and maxilla. There are one to three roots in each tooth, and they are located in the matching alveolar socket. In the healthy adult tooth, the gingiva surrounds the neck of each tooth, which is positioned above the alveolus. The part of the tooth that is visible is the crown, which is covered in enamel. Periodontal ligaments hold each tooth in place within the socket, while blood arteries and nerves supply each root of the tooth [19]. Odontogenic infections can spread to a variety of locations inside the muscles, bones, and fasciae of the face and neck. The canine space is created by the insertion of the levator anguli oris muscle and is bordered laterally by the facial skin and posteromedially by the maxilla and levator anguli oris. It is located deep to the nasolabial fold. Beyond this implantation, the maxillary canine root is frequently lengthy [20]. A maxillary canine’s infection may spread into the canine space from the tooth root. Similarly, the buccal space is created by the buccinator muscle’s insertion on the maxilla and mandible. The skin borders the buccal space laterally, while the maxilla and buccinator muscle border it medially. An infection may be able to spread to the subcutaneous tissues of the face by a maxillary molar root that extends superiorly to the insertion [20]. There are three distinct places where infections can arise from mandibular tooth infections. The lingual oral mucosa forms the superior boundary of the sublingual space, whereas the mylohyoid muscle forms the inferior boundary, the extrinsic tongue muscles medially, and the lingual cortex of the mandible forms the anterolateral boundary [20]. The mylohyoid muscle borders the submandibular space superiorly, the neck skin borders it inferiorly, and the mandible borders it laterally. Since the mylohyoid’s posterior border is open, infection can easily move from the sublingual to the submandibular spaces. Lastly, the mylohyoid muscle, the neck skin, and the anterior bellies of the digastric muscles form the superior, inferior, and lateral boundaries of the submental space [21]. The location of the tooth roots in relation to the mylohyoid line has a major role in the spread of mandibular odontogenic infections. The mylohyoid line, an oblique line that slopes inferiorly from posterior to anterior, is where the mylohyoid starts from the lingual cortex of the mandibular body and inserts on the superior surface of the hyoid bone. Sublingual space infections originate from infection spreading medially and inferiorly along dental roots superior to this line; submandibular space infections come from infection spreading along those roots inferior to the line. Spread from the submandibular area, sublingual region, or directly from the skin are more likely to cause spread to the submental space than from the tooth root. When an infection spreads to the buccal cortex, it will eventually reach the buccal space or the superficial neck tissues where the platysma inserts on the mandible [22]. Although the oral cavity’s flora is varied, anaerobes and facultative anaerobes in particular predominate. Approximately 700 different kinds of bacteria and fungus are thought to reside in the mouth cavity. Gram-positive coccus Streptococcus is by far the most widespread genus of bacteria; common species include S. mitis, S. sanguinus, S. salivarius, and S. anginosus [23]. A widespread anaerobic bacterial genus found in the oral cavity, Clostridium species, and diphtheroids are two more noteworthy gram-positive bacteria. Although gram-negative bacteria are also naturally occurring, they are more prevalent in people who have poor oral hygiene or who are ill. Prevotella, Fusobacterium, Haemophilus, and Neisseria are examples of common gram-negative bacteria in the oral cavity. Since almost all odontogenic infections are polymicrobial due to the varied bacterial flora in the oral cavity, treatment is generally directed even after culture results [23]. The mouth cavity is located where numerous important anatomical structures converge and numerous fascial planes unite. Due to this, odontogenic infections have the potential to spread swiftly and jeopardize airway patency and neurovascular systems. Early detection of mild dental infections, apical abscesses, and dental cavities can stop these potentially disastrous infections from getting worse. If this isn’t done, there may be a lot of avoidable short- and long-term consequences that have a big impact on the patient and the healthcare system [24]. Depending on the tissues and areas affected, as well as the infection’s intensity and course, odorogenic infections are categorized and treated. The most frequent odontogenic infection is periapical abscess, which is caused by dental caries [25]. Surgical drainage or debridement combined with enteral or intravenous antibiotics is a common treatment protocol. The best course of action in every case of odontogenic or orofacial infection is final dental extraction, while in some circumstances endodontic treatment may be able to preserve the tooth. Before experiencing facial or neck swelling, patients with odontogenic infections typically present with one to two weeks of increasing dental pain. These individuals frequently show up with a fever, malaise, and a recent drop in oral intake. Poor dental hygiene, previous tooth extractions, and cavities are frequently discovered with a thorough history [14]. Upon reviewing the systems, trismus, fever, malaise, odynophagia, and neck and facial pain are frequently found. Certain individuals may experience paresthesias, ocular pain, diplopia, dyspnea, and sialorrhea, depending on the tooth of origin and the direction of dissemination [14]. Due to pus in the oral cavity, patients who have experienced an intraoral abscess rupture may complain of foul-tasting and smelling discharges. A complete examination of the neck and cranial nerves should be done, just like with any infection in the head and neck, in order to rule out any further infection sources or causes. Dental infections that are left untreated have a high potential to spread to the soft tissues of the face, neck, and gingiva. As previously established, the position of mandibular dental infections in regard to the mylohyoid muscle plays a major role in their ability to progress into the neck. When cellulitis is detected and treated in its early stages in an outpatient setting, evaluation is limited to a physical examination. Acute, sensitive cervical lymphadenopathy, induration, soreness, erythema, and edema are skin and mucosal symptoms that are consistent with cellulitis. If there is reason for worry, point-of-care ultrasound can be utilized to assess for the formation of an abscess. While not required, a computed tomography scan can be helpful as a supplement for patients for whom point-of-care ultrasonography is an unsatisfactory imaging modality due to bone shadow or body habitus. Computed tomography combined with intravenous contrast can help distinguish between cellulitis and an abscess in this situation. Fat stranding and localized enhancement with contrast are symptoms of cellulitis. In cases where there is suspicion of complex abscess formation or dissemination to deep neck regions, a contrasted computed tomography scan of the neck and face should be considered. Prominent swelling of the neck and oral cavity, stridor, dyspnea, and open respiratory distress all require a quick assessment of the upper airway in a controlled environment. The most effective method for assessing this is awake flexible laryngoscopy, which can detect edema or imminent obstruction that could require immediate airway intervention [26]. An evaluation of the microbiological situation can be crucial for treating infected wounds. Making treatment decisions and anticipating the patient’s reaction to therapy can be aided by knowledge of the microbiological species that are present in the wound. All the same, these results are only meaningful when considered in the context of an infected wound, since non-pathogenic colonizing bacteria will also be found. In primary care, the most popular technique for taking a wound sample is using a swab. If the right method is applied, wound swabs can yield suitable samples for bacterial culture even if biopsy or pus aspirates are the “gold standard” procedures [27]. Before swabbing, the wound should be cleansed if it is not purulent. Although some research indicates that cleansing the wound before collecting a sample is not necessary, failing to do so frequently results in the isolation of several organisms, many of which may not be relevant and may cause laboratory findings to display “mixed bacterial flora” rather than specific species. Cleaning produces more accurate culture results by eliminating the organisms found in the surface material, which are frequently distinct from those causing the pathology. A cotton, alginate, or rayon-tipped swab should be used to superficially debride wounds after they have been cleaned with sterile saline [28]. Prior to swabbing a wound, the patient should ideally not have had antibiotic therapy, as this may have an impact on the microbiological findings. Polymicrobial odontogenic cellulitis is typified by the presence of both gram-positive and gram-negative anaerobes and aerobes. Antibiosis should therefore be broad-spectrum; in patients who are allergic to penicillins, amoxicillin-clavulanate or clindamycin are frequently effective treatments for these illnesses. Since the necrotic tooth acts as the infectious nidus, prompt dental extraction by a dentist can accelerate treatment and stop development [26]. Cellulitis can worsen into suppuration and abscess formation if treatment is postponed. Depending on whether tooth is impacted, pus will frequently gather next to the lingual or buccal cortex of the mandible or maxilla. Clinically, an abscess presents with erythema, induration, and discomfort akin to cellulitis. Physical exam findings like as fluctuance, substantial mass effect, and suppurative tooth sockets are more suggestive of an abscess. The majority of minor abscesses can be detected with point-of-care ultrasound instead of computed tomography scanning; an abscess manifests as an anechoic, occasionally loculated mass that is typically located along the cortex of the associated bone [27]. It’s advised to drain an abscess for palliation as well as source management. Drainage options for odorogenic abscesses include transoral, transfacial, transcervical, and transnasal approaches. On the other hand, transoral drainage successfully hides incisions and causes the least amount of morbidity, thus it should be used whenever possible [28]. Depending on the patient, size, and location, a mix of temporary drain installation, incision and drainage, and needle aspiration may be employed. To reduce the chance of a failed effort at formal incision and drainage, ultrasound-guided needle aspiration is sometimes utilized to determine the location of the abscess cavity. Similar to cellulitis, it is recommended to extract the troublesome tooth and treat it with antibiotics. Although a culture swab of the abscess cavity should be obtained, therapy is rarely affected by it because of the polymicrobial nature of these diseases. Oral antibiotics can be used to treat many individuals with odontogenic abscesses as an outpatient; however, intravenous antibiotics, resuscitation, and close monitoring are necessary for patients with more severe infections, immunodeficiency, or concomitant medical problems [29]. A barrier that does not physically divide two areas is present in many anatomic locations, allowing unrestricted spread to that space. There aren’t many real fascial borders in the upper cervical spaces (submandibular, sublingual, and submental), therefore infections can spread quickly between all six of the three paired areas. Fredrick von Ludwig initially characterized Ludwig angina, a rare clinical condition, as a fast and phlegmonous infection of the bilateral submandibular, submental, and sublingual regions in 1836. Since the illness appears too early to suppurate, cellulitis is the most prevalent manifestation [30]. Because of the infection’s widespread effects on the upper airway, Ludwig angina is considered an emergency. A potential airway disaster could result from the infection’s promotion of tongue and six gaps edema, which can significantly reduce the distance between the base of the tongue and the posterior pharyngeal wall and soft palate. A “bullfrog” look of the anterior neck, drooling, and respiratory discomfort are characteristic clinical features of Ludwig’s angina patients [30]. Prioritizing airway assessment and stability while concurrently putting both short- and long-term airway stabilizing methods into practice is what management should do. These patients require immediate inpatient admission and broad-spectrum intravenous antibiotics after the airway is secured. Surgical intervention may be required for debridement or infected drainage issues pertaining to the airways. Sinusitis can result from dental infections or healthy oral bacteria that travel superiorly along the maxilla. In over 40% of cases of acute bacterial maxillary sinusitis, the cause is odontogenic sinusitis. The maxillary sinus is directly related to the maxillary teeth, especially the molars and premolars. It is uncommon to notice dental implants and tooth roots inside the maxillary sinus on computed tomography or endoscopy. Even though this is frequently an unintentional discovery, infections can occasionally develop into the maxillary sinus due to improper oral hygiene or an implant that is not properly positioned. Prolonged oroantral fistulas can develop in certain patients with a history of oral or maxillofacial surgery, acting as a pathway for opportunistic infection [31]. Frequent symptoms of odontogenic sinusitis include fever, lethargy, and pressure and pain in the face. While non-odontogenic rhinosinusitis is frequently bilateral and affects other sinuses, imaging frequently reveals unilateral solitary maxillary sinusitis [32]. The course of treatment is similar and includes antibiosis, extraction of teeth or implants, and possibly endoscopic sinus surgery. After the infection has cleared up, patients with odontogenic sinusitis brought on by a persistent oroantral fistula stand to gain the most from fistula treatment [33]. Cellulitis and abscesses of the surrounding soft tissues in the masticator and submandibular regions, respectively, can develop rapidly from infections of the upper and lower jaws. The parapharyngeal, retropharyngeal, and carotid spaces of the neck can all be directly affected by these spaces since they have open boundaries with other deep neck spaces. If contaminated, the prevertebral area serves as a quick passageway into the chest and mediastinum, leading to mediastinitis or empyema. Such infections frequently require thoracic surgical intervention for optimal treatment, which carries a large increase in morbidity and death [34]. Acute osteomyelitis, a low-grade infection of the alveolus and other parts of the upper and lower jaw bones, is made possible by the close proximity of teeth to bone. When identified and treated quickly, these infections frequently go away and allow for the formation of new bone. However, chronic osteomyelitis might develop more easily if treatment is postponed, diet is inadequate, oral hygiene is poor, or tobacco usage is high. Chronic osteomyelitis usually manifests as subtle, persistent jaw pain, while it can also cause fistula formation, paresthesia due to nerve involvement, or pathologic fracture. Antibiotics and corticosteroids given intravenously can help reduce airway edema and blockage, but their effects take a long time to manifest. While mainly used for idiopathic or hereditary angioedema and epiglottitis, nebulized racemic epinephrine can also be used to reduce edema of the tongue and oropharynx when there is airway obstruction caused by an odontogenic infection. However, because it cannot be used to reduce the mass effect of abscesses or deep tissue edema, its usefulness is limited. Therapy is guided by an early assessment of the kind and degree of blockage. Evaluation can be aided by an oral and neck examination, but without an awake flexible laryngoscopy, the examination is frequently lacking [34]. With conservative treatments, different levels of obstruction can be easily temporary. Tongue base obstruction can be relieved by placing a nasopharyngeal airway or, in the case of an obtunded patient, an oropharyngeal airway. Treating obstruction resulting from parapharyngeal or retropharyngeal dissemination might not be possible with these techniques [34]. Surgical intervention or intubation may be required to permanently secure the airway, depending on the overall clinical picture. Either direct laryngoscopy or video-assisted indirect laryngoscopy will not be able to intubate the majority of patients whose blockage is severe enough to induce respiratory distress. If the glottis is visible in these situations, awake fiberoptic intubation is a safe and successful procedure. Some individuals will need surgery, such as a cricothyroidotomy or tracheostomy, if they have severe disease, acute respiratory distress, or unfavorable anatomy. In rare cases, necrotizing fasciitis and other necrotizing soft tissue infections can develop from odontogenic infections. This is a true surgical emergency, and quick airway examination and surgical debridement should be carried out, just like with any anatomic site. Although Group A Streptococcal species are frequently the cause of necrotizing fasciitis, other anaerobic bacteria and oral flora have also been linked to the condition [34]. The pulp and periodontal tissues are the source of the pathophysiology of odontogenic infections. The infection may infect fascial faces after it leaves the dentoalveolar structure, where it may cause cellulitis or the formation of an abscess. The submandibular space is the first fascial region to get implicated in an odontogenic infection among the other spaces. As in the case of the masticatory area, involvement of the submandibular space results in severe symptoms including pyrexia, respiratory distress, trismus, neck rigidity, and dysphagia [35, 36]. The discipline of maxillofacial radiology has changed dramatically with the advent of computed tomography, magnetic resonance imaging, and ultrasound, which has lessened the therapeutic dilemma for dental surgeons. Numerous illnesses affecting the maxillofacial region affect humans, many of which are odontogenic infections that are frequently seen in medical settings. These infections can occasionally result in life-threatening consequences that are challenging for the clinician to diagnose. While some authors recommend treating cellulitis with antibiotics and draining abscesses, others recommend treating both with draining. Both disorders can be challenging to diagnose clinically, and postponing diagnosis and treatment might increase the risk of emergency consequences and associated costs [37, 38]. Radiographs, which are commonly used in diagnostic procedures, have been used to assess odorogenic illnesses. Their ability to determine the precise anatomical location and propagation of infection is dubious, though. Under these conditions, ultrasonography is an efficient and quickly developing imaging technique. Its advantage is that the patient is not exposed to radiation and it is sensitive enough to identify fluid collection and the need for repeated follow-up exams. The gold standard imaging method for determining the presence of a maxillofacial fascial space infection is magnetic resonance imaging [38]. Magnetic resonance imaging’s higher tissue contrast and ability to capture anatomical plane depiction without patient movement are its main advantages. The primary disadvantage of magnetic resonance imaging is the longer time it takes to obtain images, and patients who have cardiac pacemakers or neurostimulator units are more vulnerable due to the high static magnetic field. Odontogenic infection diagnosis can be achieved using it, albeit it is an expensive and limited resource. On the other hand, ultrasonography is accurate, affordable, and widely accessible. For this reason, it might be helpful in identifying the fascial dissemination of odontogenic infection [38]. Fascial gaps are nearly always important in the oral and maxillofacial region because of the proliferation of odontogenic infections. Therefore, the spaces can be categorized based on how they relate to the upper and lower teeth as well as whether an infection can enter the primary space directly or if it needs to pass via a primary space to reach the secondary space. While infections from molars can extend to the buccal, infratemporal, or form a palatal abscess, infections from maxillary front teeth can move to the canine area. Similarly, the infection originating from the anterior mandibular teeth extended to the submental region or resulted in a gingival abscess. The Sublingual or Submandibular spaces were infected by mandibular molars. While the Submasseteric, Pterygomandibular, and Lateral Pharyngeal spaces were all affected by the infection caused by mandibular third molars [40]. When evaluating patients with space infections, the primary goals should be to detect potential sepsis symptoms, the spaces implicated, the specific etiology of the infection, and consequences such airway compromise [41]. The cases should be examined for the usual indications of space infections. A sublingual region infection manifests as difficulty articulating sounds when the tongue is raised. The voice might be muffled by a retropharyngeal or lateral pharyngeal space abscess. Should the patient be drooling, sitting in a sniffing position, or using supplementary muscles of breathing, there may be a risk of an approaching airway collapse. The uvula may veer to the other side because to lateral pharyngeal space infection or pterygo mandibular space. Individuals who have trismus and an interincisal aperture smaller than 30 mm are more likely to have trouble with endotracheal intubation48. For many orofacial infections of odontogenic origin, the routes of transmission, extent, and clinical symptoms are predetermined by the local anatomic barriers of bone, muscle, and fascia [42]. An infection is classified as extraoral if pus penetrates through the mandibular or maxillary buccal plate outside of the buccinator muscle’s attachment, or intraoral if the perforation occurs inside the muscle. Therefore, extraoral symptoms are frequently present in conjunction with infection of the lower canine teeth, lower incisors, and upper and lower molars [42]. If the apices of the affected teeth (such as the mandibular incisor, canines, premolars, and first molars) lie above the mylohyoid muscle’s attachment, the mandibular infection will manifest in the sublingual space; if it lies below, such as in the case of the second and third molars, it will manifest in the submandibular space [42]. Canine, buccal, submental, masticator, and intratemporal spaces are among the other orofacial regions that are susceptible to superficial odontogenic infections. The primary cause of buccal space infections is the apices of mandibular or maxillary bicuspid or molar teeth, which are not attached to the buccinator muscle. Due to their noticeable cheek swelling and lack of systemic symptoms or trismus, they are easily diagnosed [42]. Canine space infections cause swelling of the upper lip, canine fossa, and often the periorbital tissues. They are thought to be caused by the maxillary incisors and canines. The majority of the time, systemic indications are mild and pain is moderate. Sometimes purulent maxillary sinusitis results from an infection that directly extends into the adjacent antrum [42]. Mandibular incisors that puncture below the mentalis muscle are the source of submental area infections. The chin is hard and erythematous, and it looks extremely swollen. Masticator space infections are mostly rooted in the third molar tooth and affect the masseteric, pterygoid, and temporal space components of the masticator. These spaces communicate with the buccal and deeper peripharyngeal fascial spaces as well as each other. Trismus accompanied by discomfort in the affected body part or mandibular ramus is the indicative clinical feature of an infection. Because the infection is beneath huge muscular masses, swelling can not be noticeable. When swelling is seen, it usually has a brawny, indurated appearance, which raises the risk of mandibular osteomyelitis or cervicofacial actinomycosis. Infections in the temporal space: These infections usually start in the posterior maxillary molar teeth. Only the preauricular area and the region above the zygomatic arch may swell. The cheek, eyelids, and entire side of the face may become infected as the infection worsens. Through the inferior orbital fissure, an infection may spread directly into the orbit, resulting in proptosis, visual neuritis, and abducens nerve palsy [43]. An infratemporal space infection typically results from a tooth that is the third maxillary molar. Early in the course, very little swelling is seen, but there is noticeable trismus and pain. Late-stage symptoms, such as expansion into orbit through the inferior orbital fissure, resemble those of temporal space infections. In addition, dysphagia may arise from an internal infection that affects a region near the lateral pharyngeal wall [43]. Orofacial pain affects 3% to 12% of people, with women experiencing it at least twice as often as males. It is described as a diverse collection of neuromuscular and musculoskeletal disorders affecting the temporomandibular joint complex, surrounding osseous elements, and musculature. The most common and crippling of these are temporomandibular disorders, which affect the head and face, often resulting in headaches and neck discomfort, as well as pain in the jaw, ears, and eyes. Chronic temporomandibular dysfunction has a complex etiology that involves elements of the anatomical, functional, environmental, social, and psychological domains. Myalgia is one of the symptomatology, which typically manifests as a dull, agonizing discomfort from persistent muscle tension. Another common symptom of myofascial pain (MFP) is a dull, constant aching sensation that fluctuates in severity. According to Simons’ map, MFP causes pain upon palpation that is typically local but can also relate to other places. More chronic muscle pain issues with constant tension are more likely to be associated with MFP. In MFP, trigger points are frequently observed and can be restricted to a tense muscular band [44]. Effective pain therapy has not yet been discovered, and the multifaceted etiology of temporo-mandibular joint-related pain is far from fully understood. Clicks, crackles, and/or tinnitus are some of the symptoms of temporo-mandibular disorder in addition to pain, which can be felt on the head, neck, and face. According to the literature, non-steroidal anti-inflammatory drugs (NSAIDs), local anesthetics, intra-capsular injection of corticosteroids, occlusal appliance therapy, musculoskeletal manual approach, pharmacotherapy, patient education, home-care programs, physical therapy, and occlusal adjustment are among the conventional treatments for temporomandibular disorder. Only in cases where non-surgical therapy has failed is surgical care recommended. In terms of non-dental, conservative, and non-medical therapies, the effects of musculoskeletal manual techniques are recognized in relation to biological tissues. It entails reducing the biomechanical and neurophysiological abnormalities that lead to pain relief, enhancing function, and reducing muscle activity. Regretfully, it is still unknown how beneficial various forms of manual therapy are in treating temporomandibular dysfunction, even in light of the evidence presented in two systematic studies that suggest manual treatment can help the condition. Evidence now available indicates that a particular kind of manual therapy is useful in treating musculoskeletal pain associated with a range of mobility disorders, including those affecting the spine, head, and upper and lower limbs. An oral and maxillofacial surgeon is necessary for the treatment of facial space abscesses, which are infectious illnesses affecting the oral and maxillofacial regions. Dental infections are typically the cause of facial space abscesses in the maxillofacial region. Oral commensal bacteria, such as gram-positive (G+) cocci or anaerobic gram-negative (G−) bacilli, are the most common causative pathogens. Usually, the infection starts out as periodontitis or pulpitis and then spreads to the surrounding tissues. Dental infections can cause abscesses that develop into fascial space abscesses. Treatment for localized abscesses is simple and quick: make an incision, drain the pus, and then take antibiotics. But if the abscess is not treated quickly and stays isolated, it might spread to other fascial spaces, such as the deep neck cavity, where treatment becomes more challenging. This kind of infection progression can lead to symptoms including mediastinitis, necrotizing fasciitis, septicemia, tracheal blockage, and in severe cases, even death. As a result, it’s critical to diagnose dental infections as soon as possible and to administer the proper care, including antibiotic therapy, incision and drainage, and removal of the infection’s source [45]. When treating fascial space abscesses in the craniofacial region, antibiotic selection is just as important as surgical techniques like incision and drainage. Antibiotic sensitivity testing and bacterial cultures provide valuable information, but they can take several days to complete, and in the interim, empirical antibiotics are often used until test results are received. However, the growth of resistant bacteria as a result of the widespread and careless use of antibiotics has led to serious issues. Therefore, in order to treat and prevent oral infectious diseases, it is vital to choose an appropriate antibiotic based on bacterial cultures and antibiotic sensitivity testing. Indiscriminate use of antibiotics should be avoided. We must have a deeper comprehension of the varieties, traits, and susceptibility to antibiotics of pathogenic bacteria in oral infectious disorders in order to make this decision [46]. The majority of orthodontia-related maxillofacial infections originate in the teeth, although they can also spread to the alveolar process and deeper tissues within the maxillofacial region. A dangerous condition is spreading orthodontia-related maxillofacial infections. Deep infections can spread primarily through the facial areas of the head and neck [47]. As a biological system, the human mouth cavity is home to a wide variety of microorganisms. These microbes cause diseases when they infiltrate deeper tissues or when host resistance is weakened by bacterial infections [48]. Most orofacial infections have a dental origin, and they can range in severity from a simple periapical abscess to a serious infection affecting the facial planes in the head and neck region. In rare cases, the patient’s life may be in danger. Odontogenic maxillofacial infections are dependent on a number of variables, including the host’s defense system, muscle attachment, and tooth structure, for their clinical course and dissemination. Orbital infections, necrotizing fasciitis, cavernous sinus thrombosis, brain abscess, and mediastinitis are among the possible side effects of these illnesses. Odontogenic infections are caused by bacteria that infiltrate deeper tissues. If there are enough pathogenic bacteria present and the body is not functioning well, the infections might spread to different areas of the mouth cavity. The management of these infections therefore entails both surgical and supportive therapy. Early diagnosis, identification of microorganisms through culture and antibiotic sensitivity, prompt antibiotic treatment along with early removal of cause should prevent most complications and result in an early recovery. Humans can contract a variety of illnesses, with dental infections accounting for the majority of infections in the orofacial region. The most common infectious diseases that have been identified since antiquity and used in modern medicine are called ortogenic illnesses. Fortunately, the majority of these abscesses can be successfully treated by extracting the afflicted tooth or undergoing root canal therapy in conjunction with the incision of any soft tissue swelling (Piecuch). Antibiotic therapy is necessary, nevertheless, if drainage is not possible or the patient exhibits symptoms of systemic involvement (Guralnick). A growing percentage of patients with weakened immune systems need antibiotic treatment for opportunistic infections [49]. In 1943, as pharmaceutical corporations started manufacturing penicillin in large quantities, bacteria resistant to antibiotics started to emerge. Evolution has led to the rising occurrence of antibiotic resistance. In response to the emergence of penicillin resistance, synthetic antibiotics were developed; nonetheless, due to its efficacy, low toxicity, affordability, ease of administration, and quick availability, penicillin continues to be the empirical medication of choice for odontogenic infections [50].

3. CONCLUSION

After reviewing the report, we may draw the conclusion that staph was the most frequently found bacterium, followed by E. coli, MRSA, and klebseilla pneumonia. Likewise, among patients with fascial space infections, the most sensitive antibiotic-sensitive bacteria were those that responded to metranidazol and chloramphenicol, then clindamycin, vancomycin, amikacin, imipenem, and panicilline.
