Prevalence of Radiographically Detectable Non-syndromic Dental Anomalies amongst Orthodontic Patients - A Retrospective Study.

Abstract

Introduction: Developmental dental anomalies are variations from expected clinical appearance, shape, size, color, contour, number, eruption pattern, and degree of tooth development. Early diagnosis of such anomalies helps formulate a treatment plan and provide optimal dental care.

Materials and method: Present study was a retrospective study designed to identify and analyze non-syndromic developmental dental anomalies amongst children and adolescents aged 9 to ≤19 years of Indian origin belonging to both genders who reported for orthodontic treatment. The data were subjected to descriptive and analytical statistics; Pearson's Chi-square test, and Spearman rank correlation coefficient were used.

Results: In 1017 subjects (559 male, 458 female), a total of 569 individuals (277 male, 292 female) and 853 teeth had anomalies. The most common anomalies in the study sample were impacted with teeth (24.5%), dilaceration (10.4%), and hypodontia (6.8%). The maxillary canine was the most commonly involved in any form of anomaly. Approximately, 32.54% (n = 331) of subjects showed only one tooth anomaly, 26.74% (n = 272) of participants showed anomalies in two teeth, whereas 7.6% (n = 77) of patients showed anomalies in three or more teeth.

Conclusion: Most commonly observed anomaly in the present study was impacted teeth (24.5%). The maxillary canine was the most commonly involved tooth in any form of anomaly.
