Non-syndromic multiple unerupted supernumerary teeth : a case report

The exact aetiology of supernumerary teeth is still unknown even though many theories have been proposed to explain their presence. Abnormal reactions to a local traumatic episode, environmental factors or a developmental anomaly, and certain syndromes have been implicated as causative factors. Although a single supernumerary tooth or few teeth have been widely reported in the literature, multiple supernumerary teeth are not a common occurrence. Multiple supernumerary teeth affecting all four quadrants of the jaw is a rare dental anomaly which generally is an accidental finding on routine dental radiography. This article reports the case of non-syndromic multiple supernumerary teeth, affecting all four quadrants in a 23-year-old male, who presented to the Faculty of Dental Sciences, University of Peradeniya for routine dental treatment without any significant medical or dental abnormality. A brief review of the literature on multiple supernumerary teeth is also presented.
