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. Key Words: Dental anomalies; Peg lateral; supernumerary teeth; Talon's cusp; Enamel hypoplasia. DOI: 10.3329/bjms.v10i1.7318 Bangladesh Journal of Medical Science Vol.10 No.1 Jan 2010 pp.41-44
Highlights
Dental anomalies of crowns or roots of teeth are not uncommon
Studies quantifying the prevalence of dental anomalies in different countries representing persons of various ethnic origin have been done [4], a study representing the dental anomalies in this region has not been done so far
We found that out of the 500 school children examined 6 (1.2%) of total group had at least one developmental dental anomaly
Summary
Dental anomalies of crowns or roots of teeth are not uncommon. Anomalies of teeth shape, number & structure occur due to abnormal events in the embryological development of teeth caused by genetic &environmental factors during the morphodifferentiation or histodifferentiation stages of development [1].force and increased susceptibility to caries [2,3]. Dental anomalies of crowns or roots of teeth are not uncommon. Number & structure occur due to abnormal events in the embryological development of teeth caused by genetic &. This study was conducted to determine the prevalence of developmental dental anomalies in 500 school going children. Asymptomatic these anomalies can lead to clinical problems which include delayed or incomplete eruption of the normal series of teeth, attrition, breast feeding problems, compromised esthetics, occlusal interference, accidental cusp fracture, interference with tongue space causing difficulty in speech and mastication, temporomandibular joint pain and dysfunction, malocclusion, periodontal problems because of excessive occlusal
