mandibular second premolars with three root canals: a review and 3 case reports
نویسندگان
چکیده
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 lingual. mesiobuccal orifices were found after removing dentinal shelves. even in teeth with extremely complex root canal morphologies, conventional endodontic treatment without surgical intervention can result in adequate healing, as in these cases. clinicians should be aware of unusual root canal anatomy in mandibular premolars. very careful examination of the pulpal space, preferably with an optical device is recommended to locate any unusual orifices.

It is very important that the dentists have sufficient information about possible variations in the expected root canal configurations in order to achieve success in endodontic treatment. In addition to having adequate knowledge on the variations of the root canal anatomy, periapical radiographs from different angles, careful examination of the pulp chamber floor, and use of dental operation mi...
متن کاملNon-surgical endodontic treatment of premolars with three root canals: a case reports
To perform successful endodontic therapy, it is important to know the anatomy and morphology of the root canal system. Peculiarities with possible anatomic variations may lead to failure due to insufficient instrumentation and inadequate three-dimensional obturation of the root canal system.[1,2] Accurate radiographic examination using different horizontal angles is crucial for the endodontist ...

متن کاملRoot Canal Treatment of Maxillary and Mandibular Three-Rooted Premolars: Case Reports
Familiarity with the normal and abnormal anatomy of the root canal system is essential for successful root canal treatment. The possibility of concomitant three-rooted and three- canalled maxillary and mandibular premolars are extremely rare. The purpose of this paper was to report a case with a three-rooted maxillary first premolar and two three-rooted mandibular premolars.
متن کاملMandibular second premolar with three canals.
Mandibular premolars often show aberrant anatomy varying from one to three canals. The incidence of occurrence of 3 canals has been recorded to be 0.46 - 0.5 %. We report a case of mandibular second premolar with 3 canals, which was initially diagnosed radiographically by shift cone technique and confirmed by clinical examination. The tooth was successfully obturated and restored. It remained a...
