“…Acid etching technique using phosphoric acid is well accepted for various applications in dentistry [3][4][5][6]8,10,[12][13][14][15][16] . In the current study, the etching time has been found to affect the surface features of etched tooth tissues.…”

“…Similarly an additional 30 s etching is suggested for enamel if uniform white frosted appearance is not obtained using the recommended etching time 2) . In order to improve the adhesion of resin restorative materials to the tooth structure, the role of acid etching using phosphoric acid (35-38%) has been well documented and supported by a number of studies [3][4][5][6][7][8][9][10] . The effect of etching time on the final bond strength as well as underlying physical surface properties is not very well understood.…”

The objective of this study was to evaluate the effect of etching time on the surface properties of dental hard tissues including enamel and dentin. For this purpose, samples were prepared using extracted human teeth and treated with 37% phosphoric acid for various length of time using the set protocol. The effects of etching time on surface roughness were assessed using non-contact surface roughness profilometer and surface hardness was measured using nanoindentation technique. All results were analyzed statistically using SPSS computer software. Within the limitation of this study, it was concluded that etching time influences on the surface properties of dental hard tissues particularly the enamel. Enamel surface properties such as roughness and hardness can be altered remarkable as a matter of few seconds. Prolonged etching time than recommended is likely to increase the surface roughness and decrease surface hardness; compromising the bond strength of adhesive materials in clinical applications.

“…The lower values of bond strength obtained with the specific adhesive system combined with the silorane-based composite could be explained by the poor chemical interaction between the components of the adhesive and the composite. 4 The silorane specific adhesive system is presented in two bottles, with two different application steps. 4 However, it is considered a one-step adhesive system, with an acid adhesive.…”

“… 4 The silorane specific adhesive system is presented in two bottles, with two different application steps. 4 However, it is considered a one-step adhesive system, with an acid adhesive. 4 Such fact may explain the results, since the specific adhesive system do not strongly bond to the silorane-based composite due to its hydrophilic nature, and hydrophobic of the composite.…”

“… 1 , 2 , 3 Silorane-based composites, which are obtained from the reaction of oxirane and siloxane molecules, present low polymerization shrinkage and greater hydrophobicity, making them practically insoluble in the oral environment, while methacrylate-based composites present higher rate of polymerization contraction stress, promoting restoration debonding on cavity walls. 4 , 5 , 6 , 7 , 8 …”

ObjectivesThe aim of this study was to evaluate the effect of pre-etching on the bond strength of silorane-based composite specific adhesive system to dentin.Materials and MethodsThirty human molars were randomly divided into 5 groups according to the different bonding strategies. For teeth restored with silorane-based composite (Filtek Silorane, 3M ESPE), the specific self-etching adhesive system (Adhesive System P90, 3M ESPE) was used with and without pre-etching (Pre-etching/Silorane and Silorane groups). Teeth restored with methacrylate based-composite (Filtek Z250, 3M ESPE) were hybridized with the two-step self-etching system (Clearfil SE Bond, Kuraray), with and without pre-etching (Pre-etching/Methacrylate and Methacrylate groups), or three-step adhesive system (Adper Scotchbond Multi-Purpose, 3M ESPE) (Three-step/Methacrylate group) (n = 6). The restored teeth were sectioned into stick-shaped test specimens (1.0 × 1.0 mm), and coupled to a universal test machine (0.5 mm/min) to perform microtensile testing.ResultsPre-etching/Methacrylate group presented the highest bond strength values, with significant difference from Silorane and Three-step/Methacrylate groups (p < 0.05). However, it was not significantly different from Preetching/Silorane and Methacrylate groups.ConclusionsPre-etching increased bond strength of silorane-based composite specific adhesive system to dentin.
