Prevalence of Dental Developmental Anomalies: A Radiographic Study

Ajmal Mir | Rizwan Hamid | Mushtaq Bhat ^[3]

Abstract: Objectives:?To evaluate the prevalence of dental developmental anomalies on digital panoramic radiographs and to evaluate the frequency of anomalies regarding the disorders in shape, position and number Materials and Methods:?A total of 1000 panoramic radiographs from 496 males and 504 females, aged over 15 years were obtained from the digital database between the years of 2016 and 2017. The selected radiographs were evaluated in terms of the anomalies such as dilacerations, taurodontism, supernumerary teeth, congenitally missing teeth, fusion, gemination, tooth impaction, tooth transposition, dens invagination, and peg lateral. Then, the anomalies were compared to each other regarding the frequency of the anomaly type (morphological, positional and numerical). Data were evaluated using descriptive statistics such as frequency and percent, and statistical tests such as Chi-square (X2)?at 0.05 significant level using the Statistical Package for the Social Sciences (SPSS) version 20.0. ? Results:?The prevalence of dental anomaly was 181 (18.1%), which was slightly higher in females 92 (9.2%)) than males 89 (8.9%), however, this difference was not statistically significant (P?> 0.05). The prevalence of dilacerated teeth was 52 (5.2%), taurodontism 53 (5.3%), supernumerary teeth 5 (0.5 %), congenitally missing teeth 11 (1.1%), fusion 9 (0.09%), gemination 9 (0.09%), impaction 34 (3.4%), transposition 1 (0.1%), dens invagination 13 (1.3 %) and peg lateral was 7 (0.7%). Conclusions:?Dental anomalies are relatively common; though their occurrence is not symptomatic, they can lead to several clinical problems in patients. Detailed clinical and radiographic assessment and counseling during patient visits is a critical factor in assessing the patient's degree of difficulty to help the dentist for better preparedness for the treatment.
