Placement of a restorative material in dentin produces the possibility of pulpal injury. In vitro studies have shown that the constituents of dental biomaterials have toxic potentials. In the clinical setting, there may be an immediate reaction of the pulp to, for example, acid etching and to the placement of a bonding agent; however, in most cases the remaining dentin serves as protection agai...

Objective: The objective of this mini review is to evaluate the age-related changes in dentin and its effect on bonding.Background: Bonding poses a great challenge which can be attributed multifarious including factors such as high organic content dentin, presence dentinal tubules, continuously moist environment due fluid permeability intratubular pressure. bonding becomes more challenging with...

The main priority of rubber dam isolation was endodontic isolation against fluids and microorganisms in the oral cavity. Added to this, is the need to protect the patient against accidental aspiration or ingestion of small endodontic instruments. According to court ruling in many countries, such occurrences are considered avoidable, and can be attributed to negligence on the part of the dentist...

Commercially pure titanium for bone-anchored dental implants, submitted to a sand-blasting and acid-etching (SLA) surface treatment, has been mechanically tested and analyzed by SEM and TEM observations. A face-centered cubic titanium hydride layer grows on the polycrystalline titanium substrate with various epitaxial relationships, whose grains show also epitaxial relationships with each other...

The brittleness of dental amalgam limits its use to sites in which tensile stresses can be kept at a minimum. If the cause for the brittleness could be ascertained, then an approach to correct this problem could be devised. Physical properties of metals are ultimately manifested in, and can be explained by, their microstructure. Through the work of several researchers,1-3 means of identifying t...

The objective this study was to evaluate in vitro the bond strength of two etch-and-rise and one self-etching adhesive system after dentin irradiation with Er:YAG (erbium: yttrium aluminum garnet) laser using microtensile test. The results revealed that the groups treated with laser Er:YAG presented less tensile bond strength, independently to the adhesive system used. The prompt L-pop adhesive...

UNLABELLED Development of new materials for tooth bleaching justifies the need for studies to evaluate the changes in the enamel surface caused by different bleaching protocols. OBJECTIVE The aim of this study was to evaluate the bovine dental enamel wear in function of different bleaching gel protocols, acid etching and pH variation. MATERIAL AND METHODS Sixty fragments of bovine teeth wer...

STATEMENT OF PROBLEM Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses. However, information about the durable bond to veneering resins is still scarce. PURPOSE The purpose of this study was to investigate the effect of chemical treatments of PEEK on tensile bond strength (TBS) to veneering resins with special emphasis on surface free energy (SFE) and...

The development of dentin bonding agents has revolutionized the field esthetic and restorative dentistry. Buonocore’s discovery on enamel acid-etching followed by description hybrid layer Nakabayashi et al are some major breakthroughs which responsible for changing paradigms in adhesive dentistry.On basis mode use,dental adhesives can be divided generations. Currently, challenges lie front rese...

UNLABELLED Some surface treatments performed on titanium can alter the composition of salivary pellicle formed on this abiotic surface. Such treatments modify the titanium's surface properties and can promote higher adsorption of proteins, which allow better integration of titanium to the biotic system. PURPOSE This study aimed to evaluate the interactions between salivary proteins and titani...
