Abstract
Studies on canal configuration have demonstrated a substantial variation in the number of roots and root canals in different teeth. Maxillary and mandibular molars may have three and two roots, respectively, and generally present with three of four root canals. This case describes the presence of one single root and one root canal in all second molars of the same patient.
