Dental abscess in a tooth with intact dens evaginatus.

This article reports a case of dental abscess in a mandibular premolar with intact dens evaginatus. Dentists are advised to critically evaluate those teeth with dens evaginatus, both clinically and radiographically, before attempting prophylactic treatments. This is particularly important medicolegally in case the tooth develops symptoms shortly after the prophylactic treatment. Dentists practising in Western countries should also be aware of this dental anomaly because of the increasing global migration of people from Asia. [ABSTRACT FROM AUTHOR]
