Prevalence of dental anomalies in Indian population

Abstract

Objectives: Developmental anomalies of the dentition are not infrequently observed by the dental practitioner. The aim of the present study was to determine the prevalence of dental anomalies in the Indian population. Study Design: A retrospective study of 4133 panoramic radiographs of patients, who attended the Department of Oral Medicine and Radiology, Jodhpur Dental College General Hospital between September 2008 to December 2012 was done. The ages of the patients ranged from 13 to 38 years with a mean age of 21.8 years. The orthopantomographs (OPGs) and dental records were examined for any unusual finding such as congenitally missing teeth, impactions, ectopic eruption, supernumerary teeth, odontoma, dilacerations, taurodontism, dens in dente, germination and fusion, among others. Results: 1519 (36.7%) patients had at least one dental anomaly. The congenitally missing teeth 673 (16.3%) had the highest prevalence, followed by impacted teeth 641 (15.5%), supernumerary teeth 51 (1.2%) and microdontia 41 (1.0%). Other anomalies were found at lower prevalence ranging from transposition 7 (0.1%) to ectopic eruption 30 (0.7%). Conclusion: The most prevalent anomaly in the Indian population was congenitally missing teeth (16.3%), and the second frequent anomaly was impacted teeth (15.5%), whereas, macrodontia, odontoma and transposition were the least frequent anomalies, with a prevalence of 0.2%, 0.2% and 0.1% respectively. While the overall prevalence of these anomalies may be low, the early diagnosis is imperative for the patient management and treatment planning. Key words:Dental anomaly, prevalence, panoramic radiography.

Prevalence of Dental Anomalies in Odisha Population: A Panoramic Radiographic Study

“…The prevalence of DAs in our study was about 35.27%, which was almost near to the study conducted by Patil et al 15 a prevalence of 45.1 and 56.9%, which was higher in comparison to our study. The most prevalent DA in our study was root dilaceration which was present in 46.71% of cases.…”

Prevalence and Distribution of Developmental Dental Anomalies in Pediatric Patients

“…One of the important categories of dental symptomatology is developmental dental anomalies (7). The prevalence of dental anomalies can provide important information for both the anthropological and clinical management of patients.…”

Determination of Oral Health Status in Patients Admitted to a University Hospital: A Pilot Study

“…Hence, their clinical management is usually complicated. 31 In this study the prevalence of dental anomalies was 19.4% and hypodontia, microdontia, dilaceration and enamel hypoplasia were the most commonly detected dental anomalies. These findings were in accordance with other studies 32 however, in orthodontic patients a remarkably high rate of dental anomalies was reported.…”

“…As dental anomalies may complicate dental treatments, especially orthodontic ones, their presence should be thoroughly investigated during intra-oral and radiologic examinations and carefully considered during treatment planning. 31 The prevalence of bone manifestations in the jaws was 7.0% and the most commonly detected lesions were exostoses (4.1%), enostoses (1.0%) and fibro-osseous lesions (1.0%). To our knowledge, there are no studies that reported the prevalence of bone manifestations in the jaws.…”
