PURPOSE To evaluate the effect of 8.0% arginine and calcium carbonate, in-office desensitizing paste (Colgate Sensitive Pro-Relief Desensitizing Paste) on the shear bond strength of composites to human dental enamel. METHODS Two resin composites (Filtek Supreme, Premise) and human dental enamel were used. 16 samples per composite were prepared. Caries-free extracted human molars, not older th...

OBJECTIVE The purpose of this study was to reveal the effectiveness of non-thermal atmospheric plasma brush in surface wettability and modification of four dental substrates. METHODS Specimens of dental substrates including dentin, enamel, and two composites Filtek Z250, Filtek LS Silorane were prepared (∼2mm thick, ∼10mm diameter). The prepared surfaces were treated for 5-45s with a non-ther...

Aims: The purpose of this study was to explore the knowledge and attitude dental interns vs newly graduated dentists (NGD) towards recently introduced smart/bioactive resin composites (SDCs).
 Study Design: Cross-sectional study.
 Place Duration Study: Restorative Dentistry Department, Faculty Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia from March 2018 June 2018.

30 INTERNATIONAL DENTISTRY – AUSTRALASIAN EDITION VOL. 7, NO. 2 Nanotechnology, on the other hand, has made successful inroads into modern composite technology and continues to be the subject of considerable research work1,12,13. Nanosized inorganic fillers enable the filler content of composite pastes to be maximised while retaining excellent clinical handling properties and at the same time m...

OBJECTIVES The Affordable Care Act is predicted to increase dental benefits coverage for millions of Americans. Utilization of expanded function dental auxiliaries (EFDAs) can contribute to increased workforce capacity. Iowa currently allows EFDAs to perform certain nonrestorative procedures. This study investigated dentists' willingness to use auxiliaries for restorative procedures in order in...

OBJECTIVES Photopolymerized composites are used in a broad range of applications with their performance largely directed by reaction kinetics and contraction accompanying polymerization. The present study was to demonstrate an instrument capable of simultaneously collecting multiple kinetics parameters for a wide range of photopolymerizable systems: degree of conversion (DC), reaction exotherm,...

This study aimed to analyze the microhardness (KHN) and diametral tensile strength (DTS) of two hybrid resin composites (TPH Spectrum and Filtek Z250). To this end, the composites were polymerized with six laboratory photo-curing units (LPUs) and the results compared with an alternative polymerization method using conventional halogen light source in conjunction with additional polymerization i...

Because the recommendation to use flowables for posterior restorations is still a matter of debate, the objective of this study was to determine in a nationwide survey in Germany how frequently, for what indications, and for what reasons, German dentists use flowable composites in posterior teeth. In addition, the acceptance of a simplified filling technique for posterior restorations using a l...

The study verified the bond strength in simulated dental restorations of silorane- or methacrylate-based composites repaired with methacrylate-based composite. Methacrylate- (P60) or silorane-based (P90) composites were used associated with adhesive (Adper Single Bond 2). Twenty-four hemi-hourglass-shaped samples were repaired with each composite (n=12). Samples were divided according to groups...
