Modelling of human teeth deformation behaviour after restoration

Three-dimensional analysis of cavity wall deformation after composite restoration of masticatory teeth.

AIM The aim of the present work was to study the size of cavity wall deformation in eight class I and II defects after composite restoration. MATERIALS AND METHODS 1. Creating a geometric model - data on the size of the left maxillary second premolar were obtained from a routine craniofacial scanning of a 20-year-old patient with a 2,5 Dental CT scanner (General Electric), with high resolutio...

Restoration of endodontically treated teeth

The restoration of endodontically treated teeth is one of the most challenging situations of the dentist s̀ clinical practice, because it involves procedures related to several areas, such as Endodontics, Operative Dentistry, and Prosthetics. These restorations aim to replace the structures lost during endodontic surgery and access to both the pulp chamber and root canal system during the instru...

Fracture Strength of Severely Damaged Primary Anterior Teeth after Restoration with Composite Resin and Resin-Modified Glass Ionomer Cement

Background and Aim: Restoration of primary anterior teeth with severe caries extending to the gingival margin is challenging for many clinicians especially in uncooperative children. Resin modified glass ionomer cements (RMGICs) can be suitable for use in such cases since they require fewer application steps than composite resins. This study aimed to assess the fracture strength of severely dam...

Antioxidants reduce microleakage of resin-based composite fillings and the associated toxicity after bleaching human teeth

Background: Bleaching teeth is popular because the discoloration is a major people’s concern. This study aimed to compare the effect of three antioxidants on the microleakage of composite resin filling after bleaching teeth with 35% H2O2, thus minimizing the potential clinical toxicity of filling materials entering patients’ body. Methods: Sixty-six extracted intact teeth were included in this...
