A dentigerous cyst is an odontogenic cyst, thought to be of developmental origin. It is associated with the crown of an unerupted (or partially erupted) tooth. The cyst cavity is lined by epithelial cells derived from the reduced enamel epithelium of the tooth forming organ. Most dentigerous cysts are solitary. Multiple/bilateral cysts are usually found in association with a number of syndromes including cleidocranial dysplasia, Maroteaux-Lamy syndrome and Gorlin--Goltz syndrome (multiple OKCs). In the absence of these syndromes, the occurrence of multiple dentigerous cysts is rare. Here, we report the unusual occurrence of non-syndromic multiple dentigerous cysts.

Objective: The main objective of this study is to analyze the prevalence of age, gender distribution, etiology, anatomic distribution, and treatment of mandibular fractures. Materials and Methods: This 2-year retrospective study was carried out in few multispeciality hospitals in India. The results were collected, and descriptive statistics were analyzed using SPSS. Results: Of 180 patients that were analyzed, males and the age group of 20–30 years had a higher prevalence of mandibular fractures with road traffic accidents being the most common etiological factor. Condyle was the most common site affected. Open treatment with rigid and nonrigid fixation was the commonly used method of treatment. Conclusion: Stratification of various epidemiological studies with data obtained over a large study period and sample size must be obtained to understand the plausible factors associated with mandibular fractures for appropriate diagnosis and management of mandibular fractures.

Background: This study is done to compare and correlate the factors that would affect the prevalence, intensity, nature of bacteremia during pre-operative, intra-operative and aftermath trans-alveolar extraction of impacted mandibular third molar. Aim: The aim of this study is to study the prevalence, nature, and intensity of bacteremia among the patients with no antibiotics administered prior to trans-alveolar extraction, with and with-out periapical and periodontal infections. Materials and methods: A prospective clinical study and microbiological assessment on blood culture was conducted at Department of oral and maxillo-facial surgery in 50 patients who underwent surgical removal of im- pacted mandibular third molar teeth. Immunocompro- mised patients, patients having temperature greater than 1000 F, bleeding disorders, patients on recent antibiotic medications were excluded from the study. Results: On comparison of the pre-operative, intra- operative and post-operative intensity values, the intensity of bacteremia was significantly greater at the intra operative and post-extraction time than at the pre-extraction time. Conclusion: We conclude that the incidence, prevalence and the intensity of bacteremia during trans-alveolar ex- traction is more common in older patients and periodon- titis is more prevalent in patients with poor oral hygiene which in turn contributes to the intensity of bacteremia associated with trans-alveolar extraction of third molar. From this study, it is found that, the occurrence of bacteremia is increased with duration of the surgery, as in- cidence of bacteremia was high when the surgery lasted more than 35 minutes in general.
