objective: the aim of this study was to evaluate the effect of concepsis (a chlorhexidine gluconate based cavity disinfectant) application on composite restorations micro leakage, using two adhesive systems: excite and adhese. materials and methods: in this interventional experimental study, class v cavities were prepared on buccal surfaces of seventy-two extracted bovine incisors. the specimen...

Composite resins were introduced to the dental profession nearly 15 years ago. Developed by Dr. Bowen at the National Bureau of Standards, and first marketed by the 3M Company of St. Paul, Minnesota, this new material was enthusiastically accepted by the dental profession. While this was clearly an improvement over the traditional silicate cement which had been on the market for almost 85 years...

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...

Introduction: Indirect dental composites may have adequate clinical performance. However, the literature is scarce regarding indirect composite resins and these solutions should be considered to maintain their properties. The aim of the study was to evaluate the influence of beverages, mouthwashes and bleaching agents on the hardness of indirect composite resins. Methods: Five different brands ...

OBJECTIVES This study was performed to determine whether the combined use of one-bottle self-etch adhesives and composite resins from same manufacturers have better bond strengths than combinations of adhesive and resins from different manufacturers. MATERIALS AND METHODS 25 experimental micro-shear bond test groups were made from combinations of five dentin adhesives and five composite resin...

OBJECTIVE A systematic review was conducted to analyze Brazilian scientific and technological production related to the dental materials field over the past 50 years. MATERIAL AND METHODS This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (Prisma) statement. Searches were performed until December 2014 in six databases: MedLine (PubMed), Scopus, LILACS, ...

OBJECTIVES This study evaluated the water sorption, solubility and kinetics of water diffusion in commercial and experimental resins that are formulated to be used as dentin and enamel bonding agents. METHODS Four commercial adhesives were selected along with their solvent-monomer combination: the bonding resins were of Adper Scotchbond Multi-Purpose (MP) and Clearfil SE Bond (SE) systems, an...

The use of dental acrylics and composite resins in veterinary dentistry has become widespread. However their use is not without potential complications. All acrylics and composite resins produce an exothermic reaction during the polymerization process. The aim of the current study was to evaluate thermal conduction during the polymerization reaction of each material to offer clinical guidelines...

Dental adhesive systems used for bonding dental resins to enamel and dentin have evolved through several "generations," with changes in chemistry, mechanism, number of bottles, application technique, and clinical effectiveness. The trend in the latest generation of dental bonding systems is to reduce the number of components and clinical placement steps. The introduction of i bond, a single-bot...

objectives: repairing composite restorations is a challenging procedure especially when two different types of composites are used. this study aimed to compare the repair strength of silorane-based composite (sc) (filtek p90) with that of preheated sc, methacrylate composite (mc)(z250), flowable mc (filtek supreme plus) and different adhesive/composite combinations. materials and methods : eigh...
