“…The effectiveness of a self-etch adhesive system depends on multiple factors. The result of this study was in agreement with Moura et al, who demonstrated that self-etch systems showed lower bond strength compared to total-etch bonding agents (30) .Shinohara et al, concluded that low bond strength with questionable bonding effectiveness was achieved with self-etching adhesive systems (31) . Nakabayashi and Takarada noticed that the hydrophilic nature and evaporable solvent responsible for low bonding ability of the self-etching systems (32) .…”

Aims:The aim of this study was to evaluate the shear bond strength of the resin composite to glass ionomer cement (sandwich technique), using different types of bonding agents. Materials and Methods: Sixty Teflon mold of (5mm in diameter and 4mm in height) filled with a based type of light cured glass ionomer cement, cured for (40 seconds), randomly assigned into three groups ( n=20 ) for bonding with different adhesive materials, (Single Bond, i-bond, and Te-Econom) . The bonding applied for ( 15 seconds ). Second split of Teflon mold (3mm in diameter and 4mm in height ) placed on to the prepared specimen filled with a Tetric Ceram composite resin (shade A2) , cured for (40 seconds), the samples stored in distilled water at 37˚C for 24h ,then thermocycled water for ( 300 cycles) at (55±2˚C and 5±2˚C) with a dwell time of (30 seconds). The bond strength measured by using Universal Testing Machine with a Knife edge head placed at the interface between glass ionomer cement and composite at a cross head speed of 0.5mm/min. The modes of fracture were examined by a stereomicroscope at 20X magnification. Results :The data were analyzed using (ANOVA) followed by Duncan's Multiple Range Test at 5% .The Single bond total-etching adhesive material showed superior bond strengths than all the other materials tested . i-bond is statistically different and showed intermediary values. The TE-Econom showed the lowest shear bond strength rates and was inferior to the Single bond one. The failures were mainly adhesive fracture for both TE-Econom and Single bond adhesive materials, except for i-bond that showed 60% mixed failure. Conclusions: With the limitation of this in vitro study, the high bond strength for the total-etch (Single Bond) bonding agent not mean that self-etch adhesive systems inferior to total -etch bonding, so further studies are needed to agree that total-etch bonding agents was the better form the clinical point of view. The failures were mainly adhesive for Single Bond and TE-Econom bonding agents and mixed failure for i-bond self-etch bonding systems and this dependent on the types of different bonding agents were used in the present study.

“…Gaps/artifacts were observed in dentinal areas of adhesive/dentine interfaces, indicating that dentine bonding is likely to be influenced by more factors than enamel [49]. The observed gap in these areas may have originated from or may have been increased by air drying and desiccating the specimens for SEM observation.…”

In this laboratory study shear bond strengths of three filled and one unfilled adhesive systems to enamel and dentine were compared. Forty-eight extracted intact noncarious human mandibular molars were randomly assigned to two groups of 24 one for bonding to enamel and the other for bonding to dentine. Buccal and lingual surfaces of each tooth were randomly assigned for application of each one of filled (Prime & Bond NT (PBNT), Optibond Solo Plus (OBSP), and Clearfil SE Bond (CSEB)) and unfilled (Single Bond (SB)) adhesive systems (n = 12). A universal resin composite was placed into the translucent plastic cylinders (3 mm in diameter and 2 mm in length) and seated against the enamel and dentine surfaces and polymerized for 40 seconds. Shear bond strength was determined using a universal testing machine, and the results were statistically analyzed using two-way ANOVA, one-way ANOVA, t-test, and Tukey HSD post hoc test with a 5% level of significance.There were no statistically significant differences in bond strength between the adhesive systems in enamel, but CSEB and SB exhibited significantly higher and lower bond strength to dentine, respectively, than the other tested adhesive systems while there were no statistically significant differences between PBNT and OBSP.

“…The key characteristic of these systems is that they skip the acid etching stage prior to application 10 , greatly decreasing the level of technical sensitivity required 11 , particularly because they obviate the need for optimal dentin moisture, which is required for total-etch systems [12][13][14][15] . Unlike conventional adhesive systems, self-etch systems have added monomers added to their composition that ensure etching of the dental structure, so that, as soon as an area of the tooth is etched (or decalcified), it is immediately occupied by the resin monomer 7,16 . Due to the limited conditioning ability of self-etch adhesive systems, the hybrid layer they form is thinner 15,[17][18] as compared to that of conventional adhesive systems.…”

Objective To assess the bond strength to dentin of the Single Bond (3M ESPE) and XP Bond (Dentsply) total-etch and Adper SE Plus (3M ESPE) self-etch adhesive systems. MethodsFifteen healthy human third molars were randomly allocated across three different groups of five teeth each according to the adhesive system. The occlusal portion of each tooth was removed under refrigeration using a flexible diamond disc (EXTEC, Enfield, CT, USA) down to an area of dentin that did not reveal enamel, as confirmed under a 40X stereo microscope (Ramsor, São Paulo, Brazil RESUMO ObjetivoAvaliar o grau de resistência de união à dentina dos sistemas adesivos de condicionamento ácido total Adper Single Bond (3M ESPE) e XP Bond (Dentsply) e autocondicionante Adper SE Plus (3M ESPE). MétodosQuinze terceiros molares humanos hígidos foram utilizados, divididos aleatoriamente em três grupos de cinco dentes cada, conforme o adesivo que seria utilizado. A porção oclusal foi removida com o auxílio de um disco flexível diamantado sob refrigeração, até expor uma área de dentina que não apresentasse ilhas de esmalte, comprovado em lupa esterioscópica em aumento de 40X. A smear layer foi padronizada em lixa d'água n°600. Na sequência os sistemas adesivos foram aplicados conforme as recomendações do fabricante, exceto o Adper SE Plus que teve seu tempo de polimerização triplicado. Sobre os dentes preparados foram construídos blocos de resina composta com 5mm de altura. As amostras foram armazenadas por 24 horas a 37°C em água destilada. Utilizando o disco flexível diamantado, foram obtidos corpos de prova com formato de palitos com área adesiva menor que 1mm². Em seguida o teste de microtração foi realizado numa Máquina de Ensaios Universal numa velocidade de 0,5 mm/min. Foram utilizados o teste ANOVA e comparações pareadas de Tukey. ResultadosOs valores da resistência de união para cada sistema adesivo em Mpa foram: 96,24 (XP Bond); 72,39 (Adper Single Bond) e 49,91 (Adper SE Plus). ConclusãoDessa forma, em relação à resistência de união à dentina, os adesivos convencionais apresentaram desempenho superior ao autocondicionante.
