The study of root and root canal anatomy of molars in children is important for pediatric practice successfull. Normally the permanent mandibular first molar has two roots, one mesial and the other distal. Rarely an additional third root is seen, which is found distolingually and called as Radix Entomolaris. This extra root is typically smaller than the distobuccal root and is usually curved, requiring special attention when root canal treatment is being considered for such a tooth. The aim of the present paper is to present two cases of permanent mandibular first molars with an additional third root.
