Prevalence of Bilateral Agenesis of Maxillary Lateral Incisors and Clinical Management Options

Abstract

Background/Purpose: Agenesis is an anomaly where the tooth germ fails to differentiate completely into dental tissues resulting in congenitally missing teeth. This is one of the commonest dental anomalies. The aim of this study was to determine the prevalence of bilateral agenesis of maxillary lateral incisors. This study also reflects upon the treatment options available when there is agenesis of maxillary lateral incisors. Materials and Methods: Bilateral agenesis was considered and included in the study as agenesis and unilateral agenesis was excluded from the study. Orthopantamograms (OPGs) of 945 dental patients aged 6-30 years were examined for the agenesis of teeth. Frequencies were calculated using chi square test and the level of significance was considered if p value was <0.05. Results: The prevalence of bilateral agenesis or congenitally missing maxillary lateral incisors was at 8.2%. Conclusions: The prevalence rate of bilateral agenesis of maxillary lateral incisors is more common in females than males. An evidence based decision should be taken for the clinical management of this kind of agenesis.
