Abstract

Aims and Objectives: To evaluate the prevalence and distribution of dental anomalies among orthodontic patients from a part of Andhra Pradesh population and apply it to the whole population.
Methodology: Pretreatment records including the study models and panoramic radiographs of 600 orthodontic patients attending for the treatment between 2017-18 were evaluated for the dental anomalies (developmental) and statistical analysis using Statistical Package for Social Sciences (SPSS) version 16.0 was carried out. Chi-square test and fisher exact test was used to compare the data.
Results: out of 600 patients, 22.3% showed dental anomalies, from which 19.6% exhibited one dental anomaly and 2.6% showed more than one: missing third molars being most common(16%), followed by dilacerations of roots (3%), agenesis(3%), peg laterals(1.6%), supernumerary teeth (.66%), dens evaginatus (.66%), dens invaginatus (0%), Macrodontia(0%).
Conclusions: 22.3% of the patients showed at least one dental anomaly. Most common anomaly in the present study is missing 3^rd molars. In the maxilla prevalence of anomaly was greater for lateral incisor for agenesis and peg shape, whereas it is for 2^nd premolars in the mandible.
