The successful outcome of the endodontic therapy requires an adequate knowledge in context to anatomy of the root canal system. In most cases, the mandibular canines are thought to have just one root canal. Those presenting with an extra root and canal are usually rare, ranging from 1% to 5%. Thus, in spite of this low prevalence, variations in the anatomy and number of root canals in mandibula...

background successful endodontic treatment is dependent on the knowledge of root canal anatomy. objectives this study aims to investigate the root canal anatomy of mandibular first molars in an iranian population. materials and methods one hundred human mandibular first molars were collected and stored in 5.25% naocl. radiographic images of the teeth were taken in mesial, distal, and buccal asp...

this article describes a clinical case of mandibular second premolar with three separated canals in apical third of the root that are diagnosed and endodontically treated. sound knowledge of root canal anatomy and morphology, tactile examination of canal walls, critical interpretation of radiographs and high magnification examination are essential elements of success in complicated root canal t...

The aim of this study was to analyse the correlation between external and internal mandibular morphology in adult or adolescent normal anthropological mandibles. Lateral radiographs of 31 symmetrical mandibles were analysed. The external morphology was defined by the gonial and beta-angles. In order to analyse internal morphology, a metallic pin was placed in the mental canal on the left side b...

Anatomic and internal morphology of a root canal system is more complex and differs for each individual tooth of which mandibular premolars have earned the reputation for having aberrant anatomy. The occurrence of three canals with three separate foramina in mandibular second premolars is very rare. A wider knowledge on both clinical and radiological anatomy especially spiral computed tomograph...

Presence of extra roots and canals should be considered before initiation of root canal treatment for the success of endodontic treatment. A mandibular second premolar with three separate roots is very rare and its prevalence has been reported to be around 0.1%. This case report explains non-surgical endodontic treatment of a mandibular second premolar with three separate roots and three separa...

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.

accurately localizing the mental foramen and mandibular canal is important when administering local anesthesia and performing surgery; therefore, knowing the normal range of the possible locations is essential. our purpose was to assess the location of the mental foramen and mandibular canal in an iranian population using panoramic radiography.standard panoramic radiographies were performed. th...

OBJECTIVE The purpose of this study was to evaluate the accuracy of relative measurements from the roof of the mandibular canal to the alveolar crest in multislice (multidetector) computed tomography (MDCT) and single-slice computed tomography (SSCT). MATERIAL AND METHODS The sample consisted of 26 printed CT films (7 SSCT and 19 MDCT) from the files of the LABI-3D (3D Imaging Laboratory) of ...

Endodontic therapy of mandibular molars is a challenging task due to its varied root canal morphology. A mandibular first molar with additional buccal root (Radix paramolaris) and additional distolingual root (Radix Entomolaris) is an example of its varied anatomy. A successful management of atypical root canal configurations is an important aspect in determining the success rate of root canal ...
