“…Etching with phosphoric acid or with acidic primers changes the surface morphology and chemical composition.Moreover, the tubules orientation can change the hybrid layer formation [32]. The results of some other studies also showed that the enamel marginal leakage was similar when universal bonding systems were used with the etch and rinse or self-etch strategy which led to the conclusion that an additional step of selective enamel etching is not necessary [16]. The same study showed similar bonding to dentin for the universal bonding systems applied in both strategies.…”

“…They should be hydrophilic in order to wet the dentin surface well, they should be hydrophobic not to allow water sorption and hydrolysis after polymerization, they should be acidic enough to etch well, but not so acidic in order not to destroy some of the initiators [7]. There are only few data in the literature regarding the bonding of universal adhesive systems in case of substrate contamination [16,17]. The aims of the study were to investigate the enamel and dentin marginal seal of a universal adhesive system applied in etch and rinse and self-etch strategy, to evaluate the enamel and dentin marginal microleakage in case of saliva contamination on different steps of the adhesive application by dye penetration assessment.…”

Introduction: The aims of the study were to investigate the enamel and dentin marginal seal of a universal adhesive system applied with etch and rinse and selfetch strategy and to evaluate the enamel and dentin marginal microleakage in case of saliva contamination on different steps of the adhesive application by dye penetration assessment. Methodology: Thirty class V cavities were prepared on the buccal face (group I-etch and rinse application of universal adhesive system) and the lingual face (group II-self-etch application of universal adhesive system) of molars and bicuspids. In each group 3 subgroups were created according to the moment of the saliva contamination: subgroup 1-no contamination, subgroup 2-contamination before light curing the adhesive, subgroup 3-contamination after light curing the adhesive. The dye penetration at the adhesive interface was evaluated according to a 4-score scale. Results: In both groups increased enamel and dentin microleakage was recorded in subgroups 2 and 3 when comparing to subgroup 1. In group I saliva contamination before and after light curing the adhesive resin led to similar mean value of dentin microleakage. Increased values of microleakage were recorded in group II when comparing to group I in the subgroups where contamination with saliva was done before light curing the adhesive resin. Conclusions: Saliva contamination of the adhesive system after light curing increased enamel microleakage only when the adhesive system was applied with etch and rinse strategy. Increased dentin microleakage after contamination was recorded with both strategies of universal adhesive system application.

“…It was previously shown that Scotch Bond universal adhesive has a performance similar to that of Adper Single Bond ® 2 and Clearfil SE ® Bond; however, its microleakage at the gingival margins of Cl V cavities was higher compared to occlusal margins [25]. Also, another study revealed that the microleakage of Cl V composite resin restorations with the use of self-etch universal adhesives in the self-etch mode at the occlusal margins was less than that with the total-etch mode, and in both modes, the microleakage at gingival margins was higher than that at the occlusal margins [27].…”

To evaluate the effect of a resin coating material on the microleakage of Class V composite resin restorations with and without post-operative bleaching. Material and Methods: Eighty class V cavities (3×3×1.5 mm) were prepared and filled with Z250 XT composite resin in the buccal and lingual surfaces of 40 sound human molars. Then the samples were randomly divided into 4 groups (n=20) and treated as follows: Group A: applying a resin coating (G-Coat Plus) on the restoration, then bleaching with 40% hydrogen peroxide; Group B: Post-Operative bleaching without prior use of resin coating; Group C: applying resin coating agent, and no further bleaching; and Group D: no resin coating, no bleaching. The specimens were thermocycled and immersed in 1% methylene blue for 24 hours, then cut into sections bucco-lingually. The samples were scored regarding the amount of dye penetration under a stereomicroscope (x20). Data were analyzed with Chi-squared and Fisher exact tests (p<0.05). Results: The maximum gingival and occlusal microleakage was detected in group B, while the minimum was seen in group C. In all the groups, microleakage at gingival margins was higher than occlusal margins (p<0.001). Conclusion: Application of a resin coating is an effective method in reducing microleakage of the restorations before and after bleaching.

Purpose:This in vitro study is to evaluate the microleakage of the universal and self-etch adhesives in selective-etch and self-etch techniques by evaluating dye penetration. Materials and methods: In this study, a total of 48 restoration and caries-free maxillar or mandibular anterior teeth were used. Standardized class V cavities (1.5 mm deep, not beveled, rounded corners) were prepared on buccal surfaces of all teeth, which were gingival edges above from the enamel-cement junction. A total of 48 teeth were randomly separated into four groups. The first group was restored with Clearfil S3 Bond Plus (Kuraray, Tokyo, Japan) in the self-etch technique. The second group was restored with single bond universal (SBU) adhesive L-pop (3M ESPE, St. Paul, USA) in the self-etch technique. The third group was restored with Clearfil S3 Bond Plus (Kuraray, Tokyo, Japan) in the selective-etch technique. The fourth group was restored with single bond universal adhesive L-pop (3M ESPE, St. Paul, USA) in the selective-etch technique. Final finishing and polishing of the restorations were performed by using discs (ZenitFlex, Munich, Germany). They were thermocycled for 5,000 thermal cycles between water baths at 5°C and 55°C. All surfaces were isolated with two layers of nail polish, except up to 1 mm from the restoration margin for correct evaluation of the microleakage. The apices of all teeth were covered with a composite resin (Clearfil Majesty Esthetic, Kuraray, Tokyo, Japan). The teeth were stored in an oven with 2% methylene blue solution for 24 hours. The samples were embedded in acrylic resin in plastic molds. Results: Microleakage scores (count and percentages) for all four groups are shown in Table 2. The Kruskal-Wallis test was applied to determine the differences between microleakage scores in the four study groups at a 0.05 level of significance. No statistically significant difference was found (p > 0.05). Conclusion:The two adhesive systems showed clinically acceptable microleakage values in two different application techniques.
