Success of endodontic treatment depends on the proper identi-fication of all the canals, thorough chemomechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Usually mandibular molars have two roots with three canals but in few teeth, the number of roots and canals vary. The variation in the nu...

Root canals may be left untreated, if the dentist fails to identify their presence, leading to endodontic failure, particularly in teeth with anatomical variation in the form of extra roots or canals. Permanent mandibular fi rst molars usually have 2 roots placed mesially and distally and 3 root canals. However, radix entomolaris (RE), an anatomical variant of permanent mandibular fi rst molar,...

Radix entomolaris is a supernumerary root located distolingually on permanent mandibular molars. It considered as an anatomical variant and usually curved buccolingually. The presence of radix can be endodontically challenging to treat susceptible endodontic mishaps such ledge. This report describes the management ledge in with type-3 curvature tooth 46. Ledge was bypassed using pre-curved K-fi...

Variations in root and root canal is always a challenge and failure to recognize these variations can result in unsuccessful endodontic treatment. Mandibular molars can sometimes present a variation called radix entomolaris, wherein the tooth has an extra root attached to its lingual aspect. This additional root may complicate the endodontic management of the tooth if it is misdiagnosed or malt...

Radix Entomolaris (additional lingual root) is commonly found in mandibular first and third molars. However, its prevalence in second molars is only 23% in Indian population. A thorough knowledge of root canal anatomy and its variations ismandatory for a clinician to successfully treat such cases.The aim of this paper is to report a mandibular second molar featuring three roots, which is a rare...

Endodontic treatment plays an important role in achieving and maintaining good oral health by eliminating infection and preserving natural dentition. Success of endodontic treatment depends on accurate diagnosis and identification of all the canals. Therefore a thorough knowledge of root canal anatomy is necessary . Awareness and understanding of the presence of unusual root canal morphology co...

case presentation a 30-year-old male patient with a history of severe, throbbing, constant pain in the lower mandibular molars was referred to the department of endodontics of hamedan dental university. the patient’s medical history was noncontributory. the buccal object rule (same-lingual opposite-buccal technique) confirmed the additional root as a distolingual root (radix entomolaris). follo...
