ABSTRACT
@#Class I malocclusions with severe crowding and tooth size discrepancies may be successfully treated orthodontically with extraction therapy, and co-management with other specialists. Correction of the discrepancies will optimize occlusal result (overjet, overbite, midline shift, and smile esthetics). This is a case of a 19-year-old male with severe crowding in upper and lower teeth and peg lateral incisor. The patient had malocclusion Class I. This case was treated comprehensively and successfully using fixed orthodontic appliances with extraction of four premolars, and veneer composite for peg lateral incisor with the help of a conservative dentist at the end of orthodontic treatment.

Dens invaginatus is a developmental anomaly resulting from infolding of the surface of the tooth crown before calcification has occurred. While several mechanisms have been proposed for the cause of this phenomenon the exact etiology is not known. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. The nature of the problem may increase the risk of pulp disease and complicate any root canal treatment. Dens invaginatus has been seen very commonly in maxillary lateral incisors; however, reported cases in peg laterals are few. A case is reported here of unusual presentation of dens invaginatus in a peg lateral. The problems associated with treatment of such teeth are discussed.
ABSTRACT
Objective: Developmental disturbances of teeth contribute to dental problems encountered in general practice. These are a group of disorders where prevention is not possible, with the exception of environmental enamel hypoplasia. Surveys done on various populations have found prevalence of dental anomalies to be 5.46%. Knowledge of common dental anomalies when available can be a useful tool for forensic dentistry. Since such epidemiological data is not available for the Jodhpur population in Rajasthan, this study was conducted to determine the prevalence of developmental dental anomalies in 500 school going children. Methodology & Result: A total of 500 school children (290 male & 210 female) of age ranging between 6 - 15 years were examined clinically for developmental anomalies of teeth. Prevalence of Peg lateral, supernumerary teeth & Talon’s cusp was 0.4%, 0.6% & 0.2% respectively while 18.8% showed fluorosis induced enamel hypoplasia.
