Abstract Background Radiographic analysis of tooth morphology is mandatory for accurate calibration the degree canal curvature angle and radiographic working length to its real dimensions in case difficulty assessment protocols. This study aimed determine impact root on maintaining original axis prepared canals using a reciprocating rotary instrumentation technique. Methods image was performed ...

The current study deals with the anterior premolar pattern in the cave and brown bear lineage, and its signifi cance in species determination. The occurrence of single premolars and its combinations in skulls and mandibles is recorded for various chronological and regional groups. Both lineages stay more “conservative” in the upper than in the lower dentition, but show contrasting reduction ten...

OBJECTIVE The purpose of this study was to investigate the root/number of roots and morphology of mandibular premolars and molars in a Korean population, and to evaluate the prevalence of three-rooted mandibular first molars having distolingual (DL) roots, three-rooted mandibular second molars, and C-shaped roots in mandibular second molars. METHODS Serial axial cone-beam computed tomography ...

For finite q, we classify the countable, descendant-homogeneous digraphs in which the descendant set of any vertex is a q-valent tree. We also give conditions on a rooted digraph Γ which allow us to construct a countable descendant-homogeneous digraph in which the descendant set of any vertex is isomorphic to Γ. 2010 Mathematics Subject Classification: 05C20, 05C38, 20B27

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 firs...
