The aim was to evaluate the microtensile bond strength (mTBS) to dentin and interfacial stress in a class II cavity restored with bulk-fill or conventional composite resins and the margin interfaces. Vertical slot class II cavities in the mesial face, with the gingival end in dentin, were prepared in 72 third molars, being divided into groups (n=24): G1-Tetric N-Ceram; G2-Tetric N-Ceram Bulk-Fill; G3-SonicFill. Clearfil SE Bond adhesive system was used in all groups.

The occlusal dentin of 120 third molars was exposed. The teeth were divided into 4 groups (n=30) according to the dentin preparation mode: 1- fine grain diamond bur; 2- coarse grain diamond bur; 3- multi laminate carbide steel bur; and, 4- ultrasonic CV Dentus diamond bur.

- The study analyzed the microleakage of indirect composite inlays bonded with two different adhesives—flowable composite and resin cement—using two types of curing lights (LED and QTH).
- Thirty-two non-carious teeth were prepared, and the inlays underwent various conditioning processes, including sandblasting, etching, and application of dental adhesives before being cured.
- Results indicated no significant difference in microleakage for enamel across both adhesive groups, while in cementum, a 5% significant difference was noted, suggesting both RelyX and Filtek Flowable resins are viable for fixing inlays.
