Comparative evaluation of the regional micro-push-out bond strength of custom-made resin post system with a prefabricated resin post: an in vitro study.

Aim: The purpose of the study is to compare the regional micro-push-out bond strength of custom-made resin post and a prefabricated resin post luted using self-etch adhesive and/or etch and rinse adhesive system at various regions.

Materials And Methods: Forty freshly extracted human maxillary central incisors were selected for this study; 1.5-2-mm coronal to the cemento-enamel junction was removed with a diamond disk using a slow speed handpiece under cooling water.

Maxillary first molar with seven root canals diagnosed with cone-beam computed tomography scanning: a case report.

Introduction: The purpose of this article was to emphasize the importance of having a thorough knowledge about the root canal anatomy.

Methods: This case report presents the endodontic management of a maxillary first molar with three roots and seven canals. The clinical detection of the seven canals was made using a surgical operating microscope and confirmed using cone-beam computed tomography (CBCT) scanning.

Maxillary second molar with 5 roots and 5 canals evaluated using cone beam computerized tomography: a case report.

This case report presents the endodontic management of maxillary right second molar exhibiting 5 roots and 5 root canals. The diagnosis was confirmed with the help of cone beam computerized tomography (CBCT). The article also describes the varied morphology associated with maxillary second molar and the use of a high-end diagnostic imaging modality like CBCT in diagnosing and negotiating these anatomic variations.

A novel simplified numbering system for dental burs.

A universally accepted standardization is of great value for any material or equipment that is used globally. A single number or name should represent the particular material or instrument throughout the world. Since the dental burs are used worldwide, a single standard numbering system, which gives a unique specification for each bur in any part of the world, is mandatory.
