The study was to evaluate the performance of different materials used in dental operative simulation and compare them with those of natural teeth. Three typical phantom teeth materials were compared with extracted permanent teeth by a nanoindentation system and evaluated by students and registered dentists on the drilling sensation of the materials. Moreover, the tool life (machinability) of ne...

AIMS Dental decay is a condition that affects both temporary and permanent dentitions. Prophylactic methods for dental decays consist of: dental sealing, use of fluorides, oral hygiene and healthy diet habits. This article focuses on the frequency, dental materials and techniques of dental sealing used for caries prophylaxis in the Cluj County. MATERIALS AND METHODS The study used a set of qu...

This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...

This report evaluates a variety of dental materials with respect to MR imaging artifacts and their mechanisms of production. A 0.15-T superconducting system and an MR phantom were used in assessing imaging artifacts. Several in-vivo studies were also carried out. The dental materials were analyzed for composition and magnetic permeability and the results were compared with the artifacts produce...

The process of dental caries is determined by a delicate balance between pathological factors (bacteria and carbohydrates) that lead do demineralization and protective factors (saliva, calcium, phosphate and fluoride) that lead to remineralization. Contemporary approach to the treatment of dental caries includes preventive and prophylactic measures based on the notion of “demineralization and r...

Introduction: An accurate impression is essential to create a well-fitted dental prosthesis. This study aimed to compare the dimensional accuracy of three elastomeric materials using one-step and two-step impression techniques. Methods: In this study, 20 impressions were fabricated for each Vinyl siloxane ether (Identium), condensation silicone (Speedex), and a...

BACKGROUND Patient charges and availability of dental services influence utilization of dental services. There is little available information on the cost of dental services and availability of materials and equipment in public dental facilities in Africa. This study aimed to determine the relative cost and availability of dental services, materials and equipment in public oral care facilities ...

materials used in the body, especially the materials used in various oral cavity regions should be stable and passive without any interactions with the body tissues or fluids. dental amalgam, c omposite resins and dental cements are the materials of choice with such properties. the first attempts to produce active materials, which could interact with the human body tissues and fluids were promp...

A plethora of dental materials are successfully used for partial dental tissue repair, while innovative dental implants are used for tooth replacement. Cell-based tooth regeneration is an attractive approach that complements traditional restorative or surgical techniques for replacement of damaged dental tissues. Recent efforts focus mostly on partial tooth regeneration for the treatment of dis...
