Single-rooted pyramidal molars: A rare case report

Abstract

Anatomical variations of the first primary molars are very rare. Anatomic variation in root canal configuration, especially in multi-rooted teeth such as primary molars, makes the diagnosis and successful root canal therapy challenging. Thorough knowledge of root canal morphology and anatomical variations of primary teeth can help a pediatric dentist in successful root canal treatment. These deviations are also one of the major causes for endodontic treatment failure owing to inadequate cleaning, shaping, and sealing of root canal system. In addition, periodontally, fused roots are more prone to tooth destruction. The main purpose of the article is to present a very rare case of primary first molars with an unusual morphology as a single root called pyramidal molar. Various etiological factors are discussed briefly, and emphasis is placed on endodontic and periodontal aspects of these root canal aberrations.
