Mechanical Properties of Bisacryl-, Composite-, and Ceramic-resin Restorative Materials.

Objective: Resin-based materials used in restorative dentistry are introduced at a fast pace with limited knowledge about their properties. Comparing properties of these materials from different restorative categories is lacking but can help the clinician in material selection. This study aimed to compare mechanical properties and wear resistance of bis-acryl-, composite-, and ceramic-resin restorative materials.

Cleaning Zirconia Surface Prior To Bonding: A Comparative Study of Different Methods and Solutions.

Purpose: To evaluate resin cement bond strength after removal of salivary contamination from a zirconia surface using different cleaning solutions and air-borne particle abrasion.

Materials And Methods: One-hundred and twenty zirconia specimens (KATANA STML, Noritake) were prepared and divided into 12 groups (n = 10). Groups were subjected to a notched-edge shear bond strength test (ISO 29022) to analyze the bonding efficiency of a resin cement (Panavia V5, Kuraray Noritake Dental Inc.

Optical properties of bisacryl-, composite-, ceramic- resin restorative materials: An aging simulation study.

Objective: Compare optical properties of a bisacryl-, composite-, and ceramic-resin restorative materials pre and post artificial aging.

Methods: Bisacryl-resin (LuxaCrown [LC], DMG), resin-composite (Filtek Supreme Ultra, [Filtek SU] 3M ESPE), and ceramic-resin (Enamic, VITA Zahnfabrik) specimens were prepared. The L*, C* , and h values were measured pre and post artificial aging to determine color stability (CIEDE2000) and changes in contrast ratio (CR), transmittance block, and relative translucency parameter.

Early Detection of Oral Cancer- Dentists’ Knowledge and Practices in the United Arab Emirates.

Objectives: The aim of this study was to evaluate the knowledge, opinions and practices of dentists regarding early detection of oral cancer in the United Arab Emirates (UAE). Method: A cross-sectional study was conducted using a simple random sampling technique with a self-reported questionnaire applied to 298 dentists, working in private and public sectors in three cities (Abu Dhabi, Dubai and Sharjah) in the UAE. Dentists’ knowledge about risk factors and diagnostic concepts of oral cancer, current practices and opinions as well as interest in continuing education programs were assessed.
