Background Successful dental root canal treatments require a complete knowledge of dental anatomy and root canal morphology. Materials and Methods One hundred and forty-five cone beam computed tomography (CBCT) images were used to assess the anatomy and morphology of mandibular premolars based on Vertucci's classifications in a defined group of dental patients in Iran. The number of roots and...

background: root morphology is of utmost importance to endodontic sciences. since there are a few studies on the morphology of mandibular second molars’ roots, and some anatomical variables are not evaluated before, the aim of this study was to investigate thoroughly radicular anatomy of this tooth. materials and methods: this ex vivo study was performed on 150 intact mandibular second molars. ...

The root canal anatomy of mandibular incisors can present a number of variations . This case report illustrates the abnormal configuration and successful non-surgical endodontic management of complex canal systems in mandibular lateral incisors.

Aortic root (AoR) components provide synchronous and precise 3D deformation of the aortic root during the cardiac cycle in order to ensure closure and opening of the three leaflets over a lifetime. Any deviation from the natural 3D morphology, such as with AoR annulus dilatation, enlarged sinuses and/or dilatation of the sinotubular junction, as in the case of ascending aortic dilatation, may r...

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 ...

Lowland rice roots have a unique physiological response to drought because of their adaptation to flooded soil. Rice root attributes that facilitate growth under flooded conditions may affect rice response to drought, but the relative roles of root structural and functional characteristics for water uptake under drought in rice are not known. Morphological, anatomical, biochemical, and molecula...

Identifying and accessing all pulp canals is particularly challenging in the endodontic treatment of teeth with atypical canal configurations. This report describes the nonsurgical endodontic treatment of a maxillary first premolar with three root canals. The prevalence of this unusual morphology is reviewed and suggestions are offered to help dentists identify and treat such teeth. This case r...
