Dr Anshi Bds Mds Apical Seal Coronal Seal Maxillary First Premolar The access preparation in a maxillary molar is through the occusal surface. very often it is necessary to reduce the mesiobuccal cusp in order to obtain straight line access to mesiobuccal canal orifice. The aim of this study was to evaluate the root and canal morphology of permanent maxillary first premolars in a polish population using cone beam computed tomography scanning (cbct) and to compare the classifications by vertucci and ahmed et al. images of 350 maxillary first premolars were analyzed.
Scielo Brasil Impact Of Access Cavity Design On Fracture Resistance The most common canal configuration for the maxillary first premolar is two separate canals in one root (vertucci type iv) with a frequency of about 60–65 %. one canal that extends from the pulp chamber and dividing in the mid root into two canals (vertucci type v) can occur in 6–7 % of cases. Objectives: this systematic review analyzed the root canal morphology and configuration (rcc) of maxillary first premolars (mx1ps) and sex specific differences based on existing literature. The maxillary first premolars are predominantly 2 rooted teeth with 2 root canals. the presence of a third root is the most common anatomic variation in these teeth. To reduce the risk of bacterial both coronal and radicular access, contamination of the prepared each of which is achieved separately cavity but ultimately flow together into a single preparation.

This study aimed to analyze the root canal of maxillary premolars on cbct using a three dimensional (3d) canal navigation tool. The most prevalent root canal configuration found is type iv followed by type i in maxillary first premolar and type ii canal configuration followed by type iv canal configuration in maxillary second premolar. Techniques for coronal access cavity preparation are outlined for anterior teeth, premolars, and molars, including gaining entry, removing the pulp chamber roof, and flaring the walls. Knowledge of pulp space anatomy is essential to achieving the objectives of endodontic treatment. the advent of newer imaging techniques including three dimensional tomography has revealed and confirmed the complex and divergent anatomy of the pulp space.
