“…In another study, 77 the use of ''collimator or transmitting cone'' applied with pressure against the composite surface reduced microleakage in enamel but not in dentin. Two other studies 75,85 did not reveal any difference in dentin microleakage due to the matrix system.…”

“…74,75 Overall, less microleakage was observed at enamel margins compared to cervical dentin. 73,74,[76][77][78][79][80][81][82][83] When comparing two existing curing modes of a comparable composite technology, the light-curing material produced less leakage than the self-curing one.…”

“…75 The removal of cement excesses with a scaler or air polishing with a soft glass were effective treatments, while another air-polishing paste with round particles was unable to restore good MTBS values. 75 Comparison of Direct and Indirect Techniques-The effect of cyclic loading was evaluated on direct and indirect Class II composite restorations. It was shown 76 that next to marginal adaptation, MTBS values were superior in the indirect group.…”

“…Interfaces less affected by microleakage before the aging test were more susceptible to thermal and load cycling. 22 The deterioration of physical property and changes in morphology of dental composites may be related with bond hydrolytic breakdown between matrix/silane and filler particles or fillers degradation. 23,24 The long-term maintenance of the surface quality of materials is fundamental to improving the longevity of esthetic restorations.…”

Aim:The purpose of this study was to determine the effect of different solutions cola soft drink (CSD) and coffee on roughness and microleakage of composite resin restorations. Materials and methods:Sixty bovine incisors were prepared and restored using Filtek Z350 XT (3M/ESPE) nanoparticulate resin. The samples were divided into three groups (n = 20): A (control)-Immersion in artificial saliva (14 days); B: Immersion in coffee (14 days), for 15 minutes (3x/day) and C: Immersion in CSD for 14 days (3x/day). Then the samples were analyzed for microleakage (dye penetration) and surface roughness (atomic force microscope). The one-way analysis of variance (ANOVA) was applied to assess the surface roughness and microleakage. The Tukey's test was set at 0.05. Results:Group A (roughness-GA R ) presented significantly the lowest average surface roughness. Group C (microleakage-GC M ) showed significantly the highest average microleakage. Conclusion:It was concluded that CSD and coffee change the surface roughness and increase the microleakage of restorations.

“…1 Cementation of indirect restorations with resin cements depends greatly on the type of adhesive strategy used to hybridize the substrate, 2 where regular cements should be applied only after the application of adhesive systems [three-, two-, or one-step(s)]. 3,4 Self-adhesive cements can also be used, although there is no need of previous application of bonding agents to the substrate.…”

The aims of this study were to evaluate the effect of immediate and delayed resin cement application on the microtensile bond strength of indirect composite resin restorations and, to evaluate adhesive strategies (for regular resin cement or humidity parameters for self-adhesive resin cement). Forty-five enamel/dentin discs (0.5 mm height and 10 mm of diameter) obtained from bovine teeth were divided into nine groups (n = 5). For regular cement, the variation factors were cementation technique at three levels (immediate cementation, 5 or 30 min after adhesive system application); and type of adhesive system at two levels (three-or two-step). For self-adhesive cement, the dentin moisture was the source of variation at three levels (normal, dry, or wet cementation). The specimens were submitted to microtensile bond strength (μTBS) testing using a universal testing machine. Data were analyzed by ANOVA, Tukey's test, and linear regression. Regular cement and three-step etch-and-rinse adhesive system showed the highest values of bond strength (25.21 MPa-30 min of delay). Only for this condition, three-step adhesive showed higher bond strength than the two-step adhesive. Nevertheless, the linear regression showed that irrespective of the strategy, the use of the two-step approach when compared with three-step adhesive system decreased μTBS (p < 0.001). The failure analysis showed predominant adhesive failures for all tested groups. All groups had comparable values of bond strength to bovine dentin when the same materials were used, even in suboptimal clinical conditions.
