UNASSIGNED: Odontogenic and orofacial infections resulting from dental issues are uncommon but cause significant complications. Early intervention is crucial to prevent severe consequences, including deep neck space infections and potentially life-threatening complications. Pregnancy leads to hormonal changes, causing physiological and oral cavity alterations. These changes affect in gingival vascular system, immune response, chemical composition, pH levels, and sub-gingival flora. Managing severe neck infections during pregnancy is challenging due to potential risks for both the mother and fetus. Prompt treatment is essential to avoid complications such as airway obstruction and the associated need for emergency tracheostomy. Pregnancy can also lead to complications like preterm delivery, low birth weight, and maternal or fetal mortality.
METHODS: A 28 year old pregnant female reported to university teaching hospital to outpatient department of oral and maxillofacial surgery, with complaint of swelling over lower right side of face and reduced mouth opening. On clinical examination it was diagnosed as sub mandibular and pterygoid space infection, primary cause being 47. Looking at the severity patient was advised for incision and drainage under general anesthesia after getting a fitness.
UNASSIGNED: Untreated dental decay in pregnant women can progress to facial space infections with life-threatening consequences. In emergencies, incision and drainage may be necessary under general anesthesia to prevent severe complications.
CONCLUSIONS: This comprehensive approach not only addressed the odontogenic infection effectively but also ensured the well-being of both the mother and the developing foetus, exemplifying the importance of tailored care in managing pregnant individuals with dental concerns.

UNASSIGNED: Lemierre\'s syndrome is a rare and serious complication of pharyngitis with an estimated annual incidence of 1 in 100,000 people worldwide. It is characterized by septic thrombophlebitis of the internal jugular vein with metastatic infection, usually after oropharyngeal infection. Rare cases of Lemierre\'s syndrome have been reported to be caused by odontogenic infection.
UNASSIGNED: A 33-year-old male visited our hospital with symptoms of fever and sore throat for 16 days. The other symptoms included pain in his left neck and shoulder. In addition, metabolic syndrome was diagnosed based on waist circumference, diabetes, and hyperlipidemia. Fusobacterium necrophorum bacteria was detected using the metagenomic next-generation sequencing (mNGS) technique. The enhanced computerized tomography (CT) scan showed thrombosis of the left proximal jugular vein and brachiocephalic vein. Based on these observations, Lemierre\'s syndrome was diagnosed. The etiology was that the fillings in the root canal tooth were lost with no blood or pain about 2 weeks before the onset. The patient recovered after treatment with antibiotics and blood purification.
UNASSIGNED: Lemierre\'s syndrome should be evaluated for patients with fever, sore throat, and neck pain. If the loss of fillings from root canal therapy occurs, especially for those with metabolic syndrome, we should be aware of the possibility of this disease. Furthermore, the mNGS test can be used as a crucial supplementary diagnostic tool for patients with undetermined fever.

Tuberculosis (TB), also known as Koch\'s disease, is a chronic granulomatous disease typically caused by Mycobacterium tuberculosis (M. tuberculosis). On 24th March 1882, Dr Robert Koch discovered M. tuberculosis that caused TB. In humans, M. bovis and atypical mycobacterium may also cause this disease. According to the World Health Organization (WHO) Global Report 2022, published on 27th October 2022, the incidence of TB in India for the year 2022 is 210/100,000 population. Primarily, TB affects the pulmonary region in humans, whereas secondarily, it may affect extrapulmonary sites such as the bones and intestines via lymph nodes. In this article, we are reporting a rare case of tubercular osteomyelitis of the mandible, in which the patient reported swelling of the cheek, mimicking an odontogenic infection that led to mandibular osteomyelitis. The definitive diagnosis of tubercular osteomyelitis was made by cartridge-based nucleic acid amplification test (CB-NAAT) when the cheesy material was found during surgical debridement and curettage of the mandible. Following that diagnosis, antitubercular treatment (ATT) was started immediately for the patient, which led to the complete resolution of the disease. The patient has been on regular follow-up for the last six months with no evidence of relapse of disease. Primary TB of the mandible is very rare, with only a few reported cases in the literature.

UNASSIGNED: Stenotrophomonas maltophilia can cause rare odontogenic brain abscesses in immunocompetent patients, highlighting the importance of considering uncommon pathogens in central nervous system infections. With only three reported cases of cerebral abscesses and one pituitary abscess caused by this microorganism, tailored diagnostic methods and individualized treatment regimens are crucial for accurate management.
UNASSIGNED: Brain abscesses present diagnostic and therapeutic challenges, with Stenotrophomonas maltophilia infections being exceptionally rare in the central nervous system. We present a case of odontogenic brain abscesses caused by S. maltophilia in an immunocompetent patient, highlighting the rarity and complexity of such infections. A 66-year-old male presented with spatial-temporal disorientation and left-sided weakness. Radiological investigations revealed an expansive lesion in the right posterior frontal region. A craniotomy and drainage were performed, identifying S. maltophilia in the purulent material. The patient responded well to tailored antibiotic therapy. S. maltophilia-related central nervous system infections are infrequent, emphasizing the need for a heightened clinical suspicion in atypical cases. This case contributes to the literature, emphasizing the importance of a multidisciplinary approach for successful diagnosis and management.

The aim of this clinical audit is to evaluate the characteristics of dental infections requiring hospitalisations, which may help improve preventative and management policies. This study retrospectively evaluated the records of patients admitted to the Nepean hospital, Kingswood, New South Wales, Australia, due to dental infections between 2018 and 2019. A total of 102 patients, mostly in their thirties with equal gender distribution, were admitted with dental infections, presenting with pain (100%), swelling (99%), trismus (40.2%), dysphagia (27.4%), fever (21%) [>37 °C], tachycardia (24.8%) and tachypnoea (9.3%). Most patients (68%) presented on weekends, outside regular working hours, and public holidays. A total of 52.5% of patients had taken prior antibiotics. Dental caries, smoking, mental health issues, and illicit drug use were featured strongly. The majority of patients (56.4%) underwent treatment under local anaesthesia. The total length of hospital stay was 271 days (mean 2.7, SD 1.6). Augmentin was the most prescribed antibiotic. Complications were reported in 8.8% of the patients, primarily due to airway compromise. Dental infections leading to hospitalisations continue to be a burden on the healthcare system. A notable finding was that the presentations were primarily on weekends, outside regular working hours, and public holidays, and the majority required dental interventions under local anaesthesia. The provision of on-call emergency dental services may reduce potentially preventable hospitalisations and the length of hospital stay.

UNASSIGNED: Maxillary sinus pathology, particularly its association with odontogenic infections, is a significant concern in dentistry. This retrospective study explored the prevalence of maxillary sinus pathologies and their association with odontogenic infections in Saudi Arabia.
UNASSIGNED: This retrospective study included 411 patients aged 20-80 years. Cone-beam computed tomography was performed to identify the presence, location, and characteristics of odontogenic infections and maxillary sinus pathologies. Patients\' age and sex were also recorded.
UNASSIGNED: Sinusitis was prevalent in 50.6 % of the cases, with no significant sex or age differences in the pathology distribution. A notable association was found between odontogenic and sinus pathologies, particularly on the left side.
UNASSIGNED: A significant prevalence of sinus pathologies, particularly sinusitis, was observed, with an association between odontogenic and sinus pathologies, notably on the left side. While acknowledging the limitations of the study, these findings underscore the need for integrated dental and sinus health assessments.

UNASSIGNED: It appears that studies on the association between CRP levels and odontogenic infections are limited. The aim of this study is to determine the difference in CPR levels between the different types of odontogenic infections.
UNASSIGNED: All consecutive patients that were diagnosed and treated for dentoalveolar and fascial space infections of odontogenic origin that met the inclusion criteria were studied. The data collected were age, gender, tobacco use, alcohol intake, and drug abuse. Other collected data were pain, trismus, dysphagia, antibiotics abuse, pre-existing medical condition, pulse rate, blood pressure, respiratory rate, body temperature, white blood cell, type of odontogenic infection, type of treatment, length of hospital stay and C-reactive protein. All analysis were done using IBM SPSS version 21.0 (IBM Corp, New York, USA). P- Value less than 5% was considered statistically significant.
UNASSIGNED: A total of 44 patients with a mean age of 45.3±1.39 years ranging from 10 to 60 years were enrolled in this study. The C-reactive protein was significantly higher among patients with positive history of pain compared to those without pain (P = 0.01). The patients with fascial space infection had C-reactive protein levels higher than those with dentoalveolar infection and the difference in their means was statistically significant (P = 0.02). Likewise, the C-reactive protein was 17.5mg/dl significantly higher in the patients that stayed more than 5days in the hospital compared to those that stayed less than the same days(P = 0.03).
UNASSIGNED: The total mean of C-reactive protein of 75.4±3.53 mg/dl was greater than the critical level while the 9.62 X 109/L of WBC counts was lower than that of the reference value. Patients that had pain, fascial space infection and stayed more than five days in the hospital had higher levels of C-reactive protein following odontogenic infections.

BACKGROUND: Odontogenic maxillary sinusitis (OMS) is widely acknowledged in both the dentistry and otolaryngology fields. Recently, iatrogenic odontogenic maxillary sinusitis cases can be encountered frequently. The purpose of this study was to evaluate the effect of intraoral sinus irrigation using the small lateral window approach in patients with odontogenic maxillary sinusitis by comparing pre- and postoperative volumetric measurement of CBCT and symptoms. We surveyed 21 patients who visited the Oral and Maxillofacial Surgery Department at PNUDH from 2016 to 2022. All the patients\' information was extracted from an electronic database. The patients with a follow-up period of 2 months or more were included. The three-dimensional volumetric measurement was performed using the ImageJ program (National Institute of Health, University of Wisconsin).
RESULTS: Among 21 patients, 16 (76.1%) were male, and 5 (23%) were female. The most common type of surgery was general anesthesia (16 cases) in which oroantral fistula was present in 7 cases. In the causes of maxillary sinusitis, there were seven implant-related patients, five patients of tooth extraction, seven patients of bone grafting, and two patients in other groups. Radiographic opacity decreased by 40.15% after sinus irrigation especially in bone graft and tooth extraction cases. Clinically, symptoms improved in 17 patients (80.9%).
CONCLUSIONS: By this study, it can be concluded that maxillary sinus irrigation using the small lateral window approach is a clinically and radiologically effective treatment method for odontogenic maxillary sinusitis.

Odontogenic infections are a broad group of head and neck conditions that arise from the teeth and surrounding periodontium. These largely preventable infections disproportionately affect members of ethnic and racial minorities and low-income/uninsured groups, and result in significant costs to our health care system. Left untreated, odontogenic infections can spread to deep spaces of the head and neck and can result in life-threatening complications. The mainstay of treatment includes timely treatment of the affected teeth. These infections are a global public health concern that could be diminished with improved access to routine dental care.

Abnormalities of dental development and anatomy may suggest the presence of congenital or acquired anomalies. The detection of abnormalities, therefore, is an important skill for radiologists to achieve. Knowledge of dental embryology and an understanding of the radiologic appearances of teeth at various stages of maturation are required for the appreciation of abnormal dental development. While many tooth abnormalities are well-depicted on dedicated dental radiographs, the first encounter with a dental anomaly may be by a radiologist on a computed tomographic (CT) or magnetic resonance (MR) exam performed for other reasons. This article depicts normal dental anatomy and development, describing the appearance of the neonatal dentition on CT and MRI, the modalities most often encountered by clinical radiologists. The radiology and dental literature are reviewed, and key concepts are illustrated with supplemental cases from our institution. The value of knowledge of dental development is investigated using the analysis of consecutive MR brain examinations. Finally, the anatomical principles are applied to the diagnosis of odontogenic infection on CT. Through analysis of the literature and case data, the contrast of dental pathology with normal anatomy and development facilitates the detection and characterization of both congenital and acquired dental disease.
