INTRODUCTION The adhesive systems and the techniques currently used are designed to provide a more effective adhesion with reduction of the protocol application. The objective of this study was to evaluate the bond strength of universal adhesive systems on enamel in different etching modes (self-etch and total etch). MATERIALS AND METHODS The mesial and distal halves of 52 bovine incisors, he...

OBJECTIVE Although self-etching bonding systems (SES) are indicated to prepare dental enamel for bonding, concerns have been expressed regarding their effectiveness. The aim of this study was to analyze the etching pattern (EP) of nine SES in comparison with 35% and 34% phosphoric acid etchants (FA) on intact (IN) and ground (GR) enamel surface. MATERIALS AND METHODS Twenty-two human third mo...

A good enamel cleaning before acid etching is necessary to prepare esthetic and functional direct and indirect restorations and fissure sealants [1,2]. Plaque and discolorations are removed by dental prophylaxis technique with pumice powder or paste and rotating brush or small rubber cup [3], there are other techniques like air-flow and bicarbonate jet polisher, which are as operative as the ot...

Current dental adhesive technology involves either an etch-and-rinse or self-etching approach.8 Evidence of clinical durability exists for both approaches, albeit depending on the specific brand.4,5 Today, enamel still requires phosphoric-acid etching and thus an etch-andrinse approach to obtain a durable bond. The adhesiveenamel bond seals the cavity and even protects the more vulnerable bond ...

OBJECTIVES The paper gives an overview on the components and the polymer chemical aspects of currently used self-etching enamel-dentin primers/adhesives. In addition, the contribution of new adhesives monomers and cross-linkers exhibiting enhanced hydrolytic stability than methacrylates to improve the performance of single-bottle adhesives is discussed. SOURCES Information from original scien...

background: laser ablation has been suggested as an alternative method to acid etching; however, previous studies have obtained contrasting results. the purpose of this study was to compare the shear bond strength (sbs) and fracture mode of orthodontic brackets that are bonded to enamel etched with acid and erbium-doped yttrium aluminum garnet (er:yag) laser. materials and methods: in this expe...

PURPOSE Successful bonding of resins to teeth affected by amelogenesis imperfecta (AI) may be highly dependent on how the enamel responds to acid etching. The aim of this study was to determine, using scanning electron microscopy (SEM), the types of etching pattern achieved with 37% phosphoric acid on dental enamel of 5 clinical variants of AI, namely, pitted hypoplastic, smooth hypoplastic, X-...

BACKGROUND AND OBJECTIVES The microbial flora of the oral cavity is extremely diverse. Residual bacteria in the oral cavity may remain at the tooth restoration interface and increase the risk of developing recurrent caries. The aim of this study is to evaluate the immediate and long term antibacterial effect of polymerised self etching adhesive systems. MATERIALS AND METHODS Streptococcus mut...

Lasers were introduced into the field of clinical dentistry with the hope of overcoming some of the drawbacks posed by the conventional methods of dental procedures. Since its first experiment for dental application in the 1960s, the use of laser has increased rapidly in the last couple of decades. At present, wide varieties of procedures are carried out using lasers. The aim of this review is ...
