AIM A case of unusual Root morphology is presented to demonstrate anatomic variations in mandibular third molar. BACKGROUND The most common configuration of mandibular third molar is two Roots and three canals; however they may have many different combinations. Endodontic treatment was performed in mandibular third molar having aberrant anatomy. CASE DESCRIPTION Four Root canal orifices wer...

Introduction Variations in the root and canal morphology are a common occurrence. The clinician should have a thorough knowledge of dental anatomy and its variations in order to achieve successful and predictable outcome with root canal treatment. Maxillary first permanent molars are generally considered to be three rooted, one palatal and two buccal. The additional root canal, if present, is t...

Mandibular canines present a complex internal anatomy. There are reported cases of canines with a single root and two canals, three canals, two roots or fused roots. The existence of mandibular canines with more than one root canal is a documented fact that clinicians should keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with ...

Background Numerous researches have been done on the permanent maxillary first molars for the presence of an extra canal, especially the mesiobuccal roots for the presence of MB2 canals. Cone beam computed tomography (CBCT) has been used recently in the detection of these canals. However, literature discussing the efficacy and reliability of CBCT in the detection of these canals is scanty. Ai...

It is generally accepted that a major cause of the failure of root canal therapy is an inability to localize and treat all of the canals of the root canal system. The risk of missing anatomy during root canal treatment is high because of the complexity of the root canal system. All categories of teeth may have extra roots and/or canals, but the likelihood of finding aberrant canal configuration...

abstract : before initiating any endodontic therapy, probability of extra canals should be considered. the incidence of three canals in mandibular second premolar has been reported to be 0.46-0.5%. the present report describes nonsurgical endodontic treatment of three mandibular second premolars with three canals. in these cases, three orifices were located in mesiobuccal, distobuccal and lingu...

introduction : to achieve success in treatment, one cannot ignore the knowledge of pulp anatomy. mandibular premolars are considered to be the most difficult teeth for endodontic therapy due to high variability in their canal morphology. it is possible that a relation exists between the crown size and the number of extra canals in these teeth, so this in vitro study aims to investigate the rela...

AIM The purpose of this case report is to describe a nonsurgical endodontic treatment of a mandibular left second premolar with two separate roots and three distinct root canals. BACKGROUND In endodontics, the possible existence of extra canals must be considered before endodontic treatment is instituted. A wide morphological variation of the root canal system is known to exist. CASE DESCRI...

The meticulous knowledge of anatomic characteristics and their variations is essential for the clinician. Radix entomolaris (RE) is one such anomaly where an extra root is present on the distolingual aspect of the mandibular first molar. 18-year-old patient was referred for the root canal treatment of mandibular right and left first molars. Intraoral periapical radiograph revealed additional pe...

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...
