Intraoral radiographic diagnosis and management of an aberrant mandibular premolar: a case report

Mandibular premolars are known for their aberrant root canal variations. This is because, they are highly unpredictable and often present with a wide variety of morphological variations. Slowey et al. reported that these root canal aberrations in mandibular premolars present an endodontic challenge to the dental practitioners.Hence, these teeth may require skillful and careful root canal preparation and canal filling techniques. One of the major reasons for failure of root canal treatment can be attributed to the unobserved canals by the operator during the procedure. This article reports and discusses the successful endodontic management of a mandibular second premolar, with an atypical canal pattern that has been missed by the dentist inadvertently in the initial appointment.
