Journal of the Indian Society of Pedodontics and Preventive Dentistry. 1996 Mar; 14(1): 14-6http://imsear.searo.who.int/handle/123456789/115021The study attempts to show a number of variations in the root canal morphology of permanent mandibular first molar. The presence of variations increases the chance of failure of endodontic treatment. Knowledge about internal anatomy of the teeth is very essential for a favourable prognosis.engDental Pulp Cavity --anatomy & histologyDentition, PermanentHumansMandibleMolar --anatomy & histologyRoot Canal Preparation --methodsJournal Article
