          Abstract

          The aim of this in vitro study was to evaluate quantitatively the microleakage in class V cavities restored with one-bottle and self-etching adhesive systems with and without previous acid etching. Two one-bottle adhesive systems (Single Bond and Prime & Bond 2.1) and one self-etching adhesive system (Clearfil Mega Bond) were used in this study. One hundred and twenty sound human premolar teeth were randomly divided into 6 groups, and 20 class V restorations were prepared in the root dentin to test each bonding system. Each bonding system was used with and without acid etching. Specimens were prepared, dyed with 2% methylene blue, sectioned, triturated, and evaluated with an absorbance spectrophotometer test in order to quantify the infiltrated dye. Results were statistically evaluated by ANOVA and Tukey-Kramer test. No statistically significant differences were found among the adhesive systems when no etching agent was used. However, the Single Bond adhesive system showed statistically significant lower microleakage means than Clearfil Mega Bond and Prime & Bond 2.1 when 37% phosphoric acid was used. Single Bond and Clearfil Mega Bond adhesive systems presented similar behavior when the manufacturers' instructions were followed.

          O objetivo deste estudo in vitro foi avaliar quantitativamente a microinfiltração em cavidades classe V restauradas com a utilização de sistemas adesivos de frasco único e autocondicionante com e sem a realização de condicionamento ácido prévio. Dois sistemas adesivos de frasco único, Single Bond e Prime & Bond 2.1, e um sistema adesivo autocondicionante, Clearfil Mega Bond, foram utilizados. Cento e vinte pré-molares humanos hígidos foram divididos em seis grupos, e vinte restaurações classe V foram preparadas na dentina radicular para avaliar cada sistema adesivo. Cada sistema adesivo foi utilizado com e sem condicionamento ácido. Os espécimes foram preparados, corados com azul de metileno a 2%, seccionados, triturados e avaliados em espectrofotometria para quantificar o corante infiltrado. Os dados foram submetidos a ANOVA e ao teste de Tukey-Kramer. Nenhuma diferença estatística significativa foi encontrada entre os sistemas adesivos quando o condicionamento ácido não foi utilizado. No entanto, o sistema adesivo Single Bond demonstrou menores médias de microinfiltração comparadas às médias dos sistemas adesivos Clearfil Mega Bond e Prime & Bond 2.1 quando o condicionamento com ácido fosfórico a 37% foi utilizado. Os sistemas adesivos Single Bond e Clearfil Mega Bond demonstraram o mesmo comportamento quando as recomendações do fabricante foram seguidas.

          Resin bonding to wet substrate. 1. Bonding to dentin.

          J Kanca (1991)
          An in vitro study was undertaken to evaluate the ability of a dentin-enamel bonding system to bond to wet, as well as to dry, dentinal substrate. The All-Etch/All-Bond system was used to bond to wet and dry dentin using 10% and 37% phosphoric acid surface conditioning. The wet dentinal surfaces exhibited significantly higher bond strengths than did the dry surfaces. It is suggested that, because of the unique behavior of the resin-primer mixture, the dentinal surface is adapted to much more thoroughly and intimately when the surface is wet.

            Clinical correlations of dentin structure and function.

            D Pashley (1991)
            Dentin, a porous, fluid-filled mineralized tissue, may provide critical mechanical support to overlying enamel. Once the enamel or cementum surface seals are lost by disease or trauma, the same organization that provided critical mechanical support then becomes a liability, offering millions of fluid-filled diffusion channels from the periphery directly to the pulp. If restorative materials placed in cavities do not seal the dentin, there is a fluid-filled continuum from the cavosurface margins, around gaps between the restorative material and the tooth, to dentin surfaces, then through dentin via its tubules to the pulp. Under most conditions these channels permit bidirectional diffusion of exogenous and endogenous substances across dentin. Occasionally, hydrodynamic stimuli will produce transient, rapid movement of dentinal fluid that will induce pain. The tubules are sometimes so close together in deep dentin that their intrinsic wetness interferes with the bonding of adhesive resins. This permits the formation of gaps, microleakage, dentin sensitivity, and, occasionally, pulpal irritation. Many clinical problems such as poor dentin bonding, microleakage, dentin sensitivity, and pulpal irritation have a common denominator in the structure and function of dentin.
