Supernumerary nines: Rare after all? an overview and case series

Abstract

Supernumerary molars are rarely reported in literature. A literature review was undertaken to identify the prevalence of supernumerary nines following multiple cases attending at local oral and maxillofacial clinics. The review found a prevalence range of 0.06–0.96% for supernumerary molars, with proliferation of epithelial remnants of dental lamina (induced by pressure or ‘induction factors’) being the most accepted aetiology. This article explores supernumerary molars and their associated comorbidities, such as disruption and damage to other teeth. The case studies illustrate management techniques. CPD/Clinical Relevance: An awareness of supernumerary teeth and their management is of clinical benefit.
