Clinical management of a mandibular first molar with supernumerary distal root [radix entomolaris]

ABSTRACT

Radix entomolares, a supernumerary root on a mandibular molar, located distolingually, is an anatomical variation of the mandibular first molar. This variation requires special care in order to maintain a high success rate of root canal treatment. This paper describes the procedure for treatment of a mandibular first molar with three roots [one mesial and two distal] and four canals [two mesial and one in each distobuccal and distolingual root]. This case report reveals the importance of anatomical knowledge of root canals and preoperative radiographs.
