Tooth crown dimensions are reasonably accurate predictors of sex and are useful adjuncts in sex assessment. This study explores the utility of buccolingual (BL) and mesiodistal (MD) measurements in sex differentiation when used independently. BL and MD measurements of 28 teeth (third molars excluded) were obtained from a group of 53 Nepalese subjects (22 women and 31 men) aged 19-28 years. Stepwise discriminant analyses were undertaken separately for both types of tooth crown variables and their accuracy in sex classification compared with one another. MD dimensions had recognizably greater accuracy (77.4-83%) in sex identification than BL measurements (62.3-64.2%)--results that are consistent with previous reports. However, the accuracy of MD variables is not high enough to warrant their exclusive use in odontometric sex assessment--higher accuracy levels have been obtained when both types of dimensions were used concurrently, implying that BL variables contribute to sex assessment to some extent. Hence, it is inferred that optimal results in dental sex assessment are obtained when both MD and BL variables are used together.

Lipoid proteinosis, a very rare autosomal recessive genodermatosis, results in hyaline material deposition in the skin and mucous membrane of various organs leading to multisystem involvement. A case report of a 12-year-old female child is presented here who showed classic features of the disease with generalized thickening, hardening, and scarring of the skin and vocal cord infiltration causing voice changes. The patient also had numerous oral mucosal and dental findings. The knowledge of the clinical features of the disease may help the oral health professional in rendering the appropriate treatment in order to improve the quality of life deteriorated by the disease.

Bifid mandibular condyle with ankylosis is an extremely rare condition and may arise as a developmental or traumatic defect. It may be associated with ankylosis. We here report a case of unilateral bifid mandibular condyle with ankylosis in a 3-year-old child. This is the youngest patient reported with the condition making it one of its first kind in the literature. The detailed description of the case, its radiological findings, and the literature on bifid condyles are reviewed.
