Background and Aim: It is essential to know the internal root canal anatomy to reach a successful root canal debridement and a subsequent successful root canal obturation. Due to the importance of knowing the complexity of mid-mesial (MM) canals and isthmuses and how to deal with these anatomic variations, in this study, we examined the incidence and prevalence of the MM canal and isthmuses in ...

Human mandibular premolars have earned the reputation for having an extremely complex root and root canal morphology. The incidence of multiple roots and canals in mandibular second premolars is lower than those in mandibular first premolars. Mandibular second premolars with three root canals and separate foramina are very rare. In this case report, endodontic management of a three-rooted mandi...

A lack of agreement exists in the literature regarding the anatomical relationship of the mandibular canal to its surrounding structures such as the root apices. The purpose of this investigation was to study the spatial relationship of the mandibular canal to the posterior teeth in dried human mandibles. Twenty-two mature dried mandibles were sectioned through the root apices of the first and ...

BACKGROUND The main reason for the failure of endodontic therapy is the incomplete knowledge about the anatomical variation of root canals. One of the most important factors that leads to the failure of root canal treatment, is missed and untreated major root canals. OBJECTIVE with respect to the complexity of mandibular incisors treatment and high prevalence of the second canal, and the poss...

objective: the knowledge of anatomic landmarks’ positions, including inferior alveolar nerve’s canal, is crucial for dentist, who has to master it. it is important to know the exact location and anatomic variety of this canal for different procedures of mandibular surgeries. the aim of the present study was to evaluate inferior mandibular canal’s anatomic position by cone-beam computed tomograp...

Understanding the morphology of the root canal plays a key role in the success of a root canal therapy. Thus considerations of the anatomic variations, in the process of diagnosis and treatment of the maxillary and mandibular posterior teeth, should be done by the clinicians.1 A thorough examination of pre-operative and postoperative radiagraphs plays a critical role in endodontic success. Vari...

BACKGROUND AND AIMS The knowledge of variations in root canal morphology is critical for a successful endodontic treatment. The purpose of this study was to investigate variations in the root canal system of human mandibular first permanent molars in an Iranian population. MATERIALS AND METHODS In this study, 209 mandibular first molar teeth were decalcified, dye-injected, and cleared in orde...

background and aims. a through knowledge of the root canal morphology is required for successful endodontic therapy. the aim of this study was to investigate the root and canal morphology of mandibular third molars in kerman, a province in southeast of iran. materials and methods. one-hundred-fifty extracted mandibular third molars were collected randomly from different dental clinics in kerman...

introduction : the purpose of the present study was to evaluate the prevalence of bilateral three-rooted mandibular first and second molars in indian population. materials and methods: a total of 215 patients were screened bilaterally for mandibular first and second molar and 430 samples of periapical radiographs were obtained. the gender, symmetry, and prevalence of three-rooted mandibular fir...

anatomy of the root canal system always effects endodontic treatment outcome. mandibular premolar teeth show extreme variations in root canal morphology. first premolars usually exhibit basic one root and one canal anatomy. the occurrence of three roots in mandibular first premolar has not been commonly reported in literature. this article reports a case of successful nonsurgical endodontic man...
