“…This failure can be due to polymerization shrinkage or different linear coefficients of thermal expansion from tooth hard substances and resin materials. 18 Thermal cycles are widely used to simulate temperature changes in the mouth, generating successive thermal stresses at the tooth-resin interface. In restorative dentistry, Kubo et al 19 investigated the microleakage of self-etching primers after thermal and flexural load cycling and found that the marginal integrity of self-etching primers did not deteriorate even after thermal cycles (5000-10,000 cycles) and flexural loads.…”

“…Similarly, several other workers have shown that an increase in the number of thermal cycles was not related to an increase in microleakage of restorations. 18,20,21 Therefore, thermocycling was not performed in this study.…”

“…18 A deeper etching pattern ensures the possibility of better resin penetration, but it does not guarantee a sealant-enamel interface that is free of microleakage or better sealant retention. 18 This is supported by an in vivo study where no differences were found between sealants applied over a self-etching adhesive or H 3 PO 4 etched teeth after 24 months. 24 However, several in vitro studies do not advocate the use of selfetching adhesives on intact enamel because of significantly lower bond strengths, greater microleakage, and an etching pattern that is not deep enough to obtain good penetration of bonding resin.…”

Objective: To compare the in vitro microleakage of orthodontic brackets (metal and ceramic) between enamel-adhesive and adhesive-bracket interfaces at the occlusal and gingival sides produced by self-etching primer system with that of conventional acid etching and bonding. Materials and Method: Sixty freshly extracted human mandibular premolar teeth were used in this study. The teeth were separated into four groups of 15 teeth each and received the following treatments: Group 1, 37% phosphoric acid gel ϩ Transbond XT liquid primer ϩ stainless steel bracket; Group 2, Transbond Plus Self-Etching Primer (TSEP) ϩ stainless steel bracket; Group 3, 37% phosphoric acid gel ϩ Transbond XT liquid primer ϩ ceramic bracket; Group 4, TSEP ϩ ceramic bracket. After curing, specimens were further sealed with nail varnish, stained with 0.5% basic fuchsine for 24 hours, sectioned and examined under a stereomicroscope, and scored for microleakage for the enamel-adhesive and bracket-adhesive interfaces from both occlusal and gingival margins. Statistical analyses were performed using Kruskal-Wallis and Mann-Whitney U tests. Results:The gingival sides in all groups exhibited higher microleakage scores compared with those observed in occlusal sides for both adhesive interfaces. Enamel-adhesive interfaces exhibited more microleakage than did the adhesive-bracket interfaces. Brackets bonded with self-etching primer system showed significantly higher microleakage at the enamel-adhesive interface of the gingival side. Conclusions: TSEP causes more microleakage between enamel-adhesive interfaces, which may lead to lower bond strength and/or white-spot lesions.

“…4 Phosphoric acid etching creates microporosities in enamel and increases the enamel surface area and wettability and, consequently, the spread and penetration of resin adhesives. 5 Phosphoric acid treatment creates a porous surface that is penetrated by a low-viscosity resin bonding agent. After polymerization of the bonding agent, a durable attachment to the enamel surface is achieved by micromechanical interlocking.…”

This study evaluates the effect of phosphoric acid etching of enamel margins on the microleakage of a simplified all-in-one and a self-etching adhesive system in comparison to a conventional total-etch system. SUMMARYSixty buccal Class V cavities with beveled enamel margins were made at the cemento-enamel junction of extracted human premolars and randomly divided into five groups of 12 specimens. Clearfil SE bond was applied to Group 1; Group 2 had 35% phosphoric acid etching of the enamel margins plus Clearfil SE Bond; Group 3 was administered iBond; Group 4 had 35% phosphoric acid etching of the enamel margins plus iBond and Scotchbond Multi-Purpose was used on Group 5. All the groups were restored with a resin composite. After 24 hours of storage in 100% humidity, the samples were thermocycled, immersed in a dye solution and sectioned buccolingually and microleakage of the enamel margins was evaluated on a scale of 0 to 2. Differences among Groups 3 and 4 and Groups 3 and 5 were significant (p<0.05); however, no statistically significant differences were found between the other groups (p>0.05). The current study shows that simplified all-in-one adhesive systems need

The purpose of this study was to analyze, by confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM), the morphology of sealant/enamel interface after surface treatment with Biosilicate. Before pits and fissures sealing, the occlusal surfaces of 10 sound human molars were sectioned perpendicularly at the fissures in order to obtain three slices for each tooth. Slices were randomly assigned into three groups (n = 10) according to sealing protocol: Group 1- Acid etching + Biosilicate + glass ionomer-based sealant (Clinpro XT Varnish, 3M ESPE); Group 2- Acid etching + glass ionomer-based sealant (Clinpro XT Varnish, 3M ESPE); Group 3- No sealing. All slices were subjected to thermal cycling (5,000 cycles; 5-55°C; dwell time: 30s). Half of the slices from each group (n = 5) were analyzed by CLSM and the other half by SEM. Groups 1 and 2 were also submitted to EDS analysis and their data were evaluated by Two-Way ANOVA e Tukey's test (α=5%). EDS data analysis showed higher amounts of silicon (Si) ions than calcium (Ca) ions in Group 1 (P < 0.05); Group 2 presented higher amounts (P < 0.05) of Ca ions than Si ions. It may be concluded that the use of Biosilicate for surface treatment did not affect the morphology of glass ionomer-based sealant/enamel interfaces.
