Dens invaginatus is one of the most common anomalies of tooth structure. It is caused by the invagination of the crown surface during odontogenesis that enters the pulp chamber of the affected tooth. Depending on the complexity of invagination, the tooth might present with pulp necrosis, open apex and a complicated root canal system. This case report presents an Oehlers' type 2 dens-invaginatus...

A patient presented with chronic periapical periodontitis on tooth 45. The root canal was re-treated and a wide apical perforation was closed with MTA® as an apical plug. At reevaluation six month later, the tooth presented with increased mobility, bleeding on probing and probing pocket depths of 9 mm. Despite good periapical healing radio graphically, the tooth showed signs of localized margin...

     Introduction: Objective: This study aimed to assess the possible variations in root canal anatomy and topography of the apices of first and second maxillary molars. Materials and methods: A total of 67 first and second maxillary permanent molars were collected. Access cavity was prepared and 2% methylene blue was injected. The teeth were demineralized by 5% nitric acid and cleared with met...

The absence of a natural apical constriction in permanent tooth makes endodontic treatment a challenge. Traditionally, calcium hydroxide was used for inducing the formation of an apical barrier. Currently, mineral trioxide aggregate (MTA) has shown promising results for apexification procedures. In an open apex, it is imperative to limit the MTA placement within the confines of the root canal f...

Purpose: This study aims to assess the effect of voxel size on trabecular microstructural evaluation onhuman cadaver mandiblesusing cone beam computed tomography (CBCT) images.
 Methods: Twenty two Volumes Interest were obtained from human mandibles which scanned in three different sizes using CBCT. Scanning performed 0.125 mm (Group 1), 0.2 2) and 0.3 3) sizes. Regions interest are calcul...

Coronary artery disease remains a common problem in industrialized countries. Percutaneous coronary interventions are usually performed utilizing the femoral approach. Arterial puncture-closing devices have been developed in hope to avoid manual compression and shortening the period of rest. In a recent meta-analysis in the Journal of the American Medical Association these devices have shown on...

This pattern collection helps to define, implement and package Plug-Ins specific to an extensible application. Central patterns are the Plug-In and the Plug-In Contract between the Plug-In and the application; afterwards patterns for packaging and registration of Plug-Ins are explored. Process and organisation patterns complement the general technical patterns, and support the technical flexibi...
