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...

AIM To analyse the anatomy of the root canal system of maxillary premolars with three distinct roots using high-resolution computed tomography (μCT). METHODOLOGY Ten three-rooted human maxillary premolars were scanned transversally from crown to apex at 42μm intervals using a high-resolution desktop μTC system (Skyscan 1072). The images were processed and analysed for the following features: ...

Mandibular premolars have earned a reputation for having aberrant anatomy. The occurrence of three canals with three separate foramina in mandibular premolars is very rare. If predictable treatment of a three rooted mandibular premolar is planned, precise knowledge of clinical and radiographic anatomy is absolutely necessary. These teeth may also require special shaping and obturating technique...

Anatomical variations must be considered in clinical and radiographical evaluations during endodontic treatment. Access cavity modifications may be required for stress free entry to complex anatomy. Higher magnification and illumination can be useful for access cavity preparation and to recognize and locate additional canals. This article describes the diagnosis and clinical management of two c...

PURPOSE This study aimed to investigate the clinical anatomy of lower premolar roots in a Spanish population by using cone-beam computed tomography (CBCT), correlating findings with patient gender and tooth type. MATERIALS AND METHODS Using 70 CBCT images, we evaluated 126 healthy, untreated, well-developed lower premolars. The number and morphology of roots and root canals, and the foramina ...

Abstract Background The objective of this study was to use CBCT look into the root canal morphology maxillary premolars in a Saudi Arabian subpopulation and associate results existing classifications. Methods sample size for analysis 500 right left untreated first second with fully formed roots from 250 residents (125 male 125 female). following observations were made using on teeth related: (1...

Objective: The study aimed to evaluate the variations in RCM of mandibular first premolars (MFP) south Indians and also evaluated gender dimorphism contralateral symmetry pattern. Methods: 200 Cone Beam Computed Tomography (CBCT) images MFP patients above 18 years were analyzed for root canal morphology after excluding distorted images, endodontically treated tooth or fractured root. teeth care...
