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 3rd molars. In the maxilla prevalence of anomaly was greater for lateral incisor for agenesis and peg shape, whereas it is for 2nd premolars in the mandible.
