“…In the past, many studies have failed to clearly demonstrate a close relationship between bond strength and microleakage [41,42]. This may be due to differences in fracture modes between the bond strength tests and the microleakage tests.…”

Objectives: The incidence of non-carious cervical lesions (NCCLs) has been increasing.The clinical performance of resin composites in NCCLS was previously unsatisfactory due to their non-retentive forms and margins lying on dentin. In order to address this problem, a lot of effort has been put into developing new dentin adhesives and restorative techniques. This article discusses these challenges and the criteria used for evaluating clinical performance as they relate to clinical studies, especially long-term clinical trials. Polymerization contraction, thermal changes and occlusal forces generate debonding stresses at adhesive interfaces.Methods: In laboratory studies, we have investigated how these stresses can be relieved by various restorative techniques and how bond strength and durability can be enhanced. Lesion forms, restorative techniques, adhesives (adhesive strategies, bond strengths, bond durability, and the relationship between enamel and dentin bond strengths) were found to have a complex relationship with microleakage. With regard to some restorative techniques, only several short-term clinical studies were available.

“…In this study, the specimens were kept in each bath for 30 seconds. For constant temperature aging, many thermal aging regimes have cited 37°C as an appropriate temperature; while for extreme temperature ageing effects, a limited temperature range of 0-67°C has been adopted [30][31][32][33][34] . In this study, the temperature range was between 5 and 55°C, which was claimed by various studies to be most clinically relevant 22,35,36) .…”

The purpose of this study was to examine the microleakage of three different fissure sealants after they were aged by mechanical loading and thermocycling in vitro. To this end, a bonding agent (Prime & Bond ® NT) and three different fissure sealants (Clinpro, Helioseal F, Teethmate F1) were used, whereby microleakage was evaluated using a dye penetration method after mechanical loading and/or thermocycling. Sealant-treated teeth were allocated into four groups: mechanical loading (50,000 times), thermocycling (10,000 times), mechanical loading (50,000 times) + thermocycling (10,000 times), and one control group. For each fissure sealant, both experimental and control groups showed statistically significant differences in average microleakage score (p<0.05). Further, for each fissure sealant, the highest average microleakage score was obtained in mechanical loading + thermocycling group. When comparison was done for each aging method, the average microleakage scores showed statistically significant differences among the three fissure sealants (p<0.05). Based on the results of this study, it was also concluded that it is necessary to develop reliable in vitro test methods for dental materials.

“…Bond strength is more predictive of a material' s retentive potential 12) . We observed the bonding agent within the cavity and assessed the film thickness of the adhesive layer along the cavity wall and measured microtensile bond strength at different sites of the cavity wall to better understand the bonding agents as an interfacial material in clinical situation.…”

The purposes of this study were to examine the variability of adhesive thickness on the different site of the cavity wall when used total-etch system without filler and simplified self-etch system with filler and to evaluate the relationship between variable adhesive thickness and microtensile bond strength to the cavity wall.A classⅠcavity in six human molars was prepared to expose all dentinal walls. Three teeth were bonded with a filled adhesive, Clearfil TM SE bond and the other three teeth were bonded with unfilled adhesives, Scotchbond TM Multi Purpose. Morphology and thickness of adhesive layer were examined using fluorescence microscope. Bonding agent thickness was measured at three points along the axial cavity wall, edge of cavity margin ( (r ri im m) ), halfway down each cavity wall ( (h hl lf f) ), internal angle of the cavity ( (a an ng g) ). After reproducing the adhesive thickness at r ri im m, , h hl lf f and a an ng g, , micro-tensile bond strength were evaluated.For both bonding agents, adhesive thickness of a an ng g was significantly thicker than that of r ri im m and h hl lf f (P < 0.05). As reproduced the adhesive thickness, microtensile bond strength was increased as adhesive thickness was increased in two bonding agents.Adhesive thickness of internal angle of the cavity was significantly thicker than that of the cavity margin and the halfway cavity wall for both bonding agents. Microtensile bond strength of the thick adhesive layer at the internal angle of the cavity was higher than that of the thin adhesive layer at the cavity margin and the halfway cavity in the two bonding systems.
