Clinical Relevance The flowable resins evaluated in this study showed leakage patterns (micro and nano), indicating that the bonding system used did not achieve perfect sealing at the restortion/dentin interface.

Clinical Relevance Decreased leakage was associated with Adper Scotchbond Multi-Purpose (total etch) and iBond (self-etch) systems in Class V resin composite restorations. All adhesive systems performed best when bonded to enamel compared to dentin surface anatomy. Clinicians should be aware that strict adherence to manufacturer instructions, when using these materials, is of primary importance.

Clinical Relevance Class V restorations are a common challenge to clinicians. These restorations involve problems, including isolation, adhesion, insertion technique, finishing and polishing. In order to solve these problems, several techniques have been developed. This article describes a new technique for the restoration of Class V cavities, one that eliminates rubber dam isolation and avoids any contamination. If used properly, this technique also provides good cervical contour, reducing or eliminating finishing and polishing procedures.

Clinical Relevance Surface sealants, when applied to Class V resin composite restorations, can contribute to a significant reduction in microleakage, thus enhancing marginal integrity.

Clinical Relevance When placing a Class II resin composite restoration, the use of sectional matrix systems and separation rings to obtain tight proximal contacts is recommended.

Clinical Relevance Fiber inserts incorporated at the gingival floor of Class II composite restorations resulted in a significant reduction of microleakage scores as compared to restorations made without inserts. This may lead to a reduced incidence of recurrent caries.

Clinical Relevance Even though marginal gap size was not shown to be a direct predictor for the extent of microleakage in resin composite restorations, both material and placement technique appear to be important determinants in microleakage and, thus, probably in clinical outcomes.

Introduction: Some studies have shown that laser irradiation on unpolymerized adhesives can improve composite-dentin adhesion. The aim of the present study was to evaluate the effect of the diode laser (810 nm) on the microleakage of multi-mode adhesive systems at enamel and dentin margins of composite restorations. Methods: Classic class V boxes were prepared on 48 sound premolar teeth and randomly divided into 6 groups (n=16). In the control groups, Scotchbond Universal (SBC), G-Premio (GBC), and Ambar U (AMC) were used by a self-etch mode. In the test groups (SBL, GBL, ABL), the 810 nm diode laser was irradiated (1 W) for 10 seconds before the polymerization of the adhesive. The boxes were restored by the resin composite. After finishing and polishing, the samples were thermocycled (5°C to 55°C) for 1000 cycles and then immersed in 0.1% methylene blue dye (48 hours). Dye penetration through the gingival and occlusal margins was measured by Stereomicroscope. The data were analyzed at the 5% significance level using Kruskal-Wallis and Mann-Whitney U tests. Results: Significant differences were found between the control and test groups (P<0.05). The occlusal margins of the SBL and GBL groups and the cervical margin of the SBL group exhibited the lowest microleakage (P<0.05). The AM control group showed maximum microleakage at cervical and occlusal margins. Conclusion: The irradiation of the 810 nm diode laser on the unpolymerized universal adhesive systems in a self-etch mode caused a significant reduction in enamel and dentin marginal microleakage of composite restorations.

Clinical Relevance Over a two–year observation period, ScotchBond Multi-Purpose was found to have significantly superior marginal adaptation compared to Adper Prompt. Restorations using retention forms showed a significantly higher retention rate in an experimental adhesive and significantly less marginal discoloration in all three adhesives.

Clinical Relevance The types of matrices assessed, metal or transparent, circumferential or sectional, straight or pre-contoured, were not able to adequately reconstruct all the characteristics of the proximal contact area of an intact tooth in Class II resin composite restorations.
