Abstract:
Impaction of teeth is a well-documented phenomenon, and multiple cases have been reported in various sites in the oral and perioral structures. However, to our best knowledge, no single case has been reported of an impacted premolar with its crown lying in trifurcation of the roots of the neighbouring molar and its root projecting into the maxillary sinus. This unique case was managed by a transantral surgical extraction. This article aims to describe, by means of case report and review of the literature, the characteristics and occurrence of ectopic retention of the maxillary premolars. Different diagnostic procedures and surgical approaches for the removal of such impacted teeth are discussed. This case report and review emphasise the importance of using the cone-beam computed tomography in the diagnosis and planning of management strategy for impacted teeth in close proximity to the roots of the surrounding teeth and other structures.
