Context:Supernumerary teeth or hyperdontia is an additional tooth, teeth or tooth like structures that either have erupted or remain unerupted in addition to the 20 deciduous and 32 permanent teeth. Supernumerary teeth may occur in isolation or as part of a syndrome or developmental abnormality.Aims:A retrospective study was conducted to analyze the prevalence of supernumerary teeth in a group of South Indian nonsyndromic population.Settings and Design:A total of 2400 radiographs were examined for the presence of supernumerary teeth.Subjects and Methods:All the radiographs were examined for the presence of supernumerary teeth, their location, morphology, and number.Statistical Analysis Used:Cross-tabulation using statistical analysis software (SPSS version 16).Results:The study results showed the prevalence to be 1.2% with 44.83% of them having single supernumerary teeth. Their prevalence was more in males and the maxillary posterior region was the most common location.Conclusions:Knowledge about the supernumerary teeth is important for dental clinicians as they are relatively common but are detected as an incidental finding in a radiograph. A routine screening panoramic radiograph is mandatory for every patient to prevent the possible complications associated with it.

Leprosy is a chronic infection caused by Mycobacterium leprae, GHA. Hansen first identified the organism in 1873, so called Hansen disease. Mycobacterium leprae is a bacillus that presents a peculiar tropism for the skin and peripheral nerves. The upper airway has a great importance as a route of M. Leprae infection. The clinical spectrum of leprosy ranges from the tuberculoid form (TT) to the disseminative and progressive lepromatous form (LL). Cell-mediated immunity is considered to be the crucial defence against the disease and the magnitude of this immunity defines the extent of the disease. Facial lesions in leprosy can occur in all form of the disease and also in lepra reaction, oral lesions are rare but, when present, occur in the lepromatous form.
