Abstract: The aim of this study was to evaluate the effect of photoactivation methods, resin liners, and the association of these techniques on the marginal adaptation of composite restorations. One-hundred-and-twenty bovine incisors were selected. A circular cavity was prepared in a flat dentin area on the buccal surface and the Scotchbond Multi Purpose system was applied. These teeth were assigned to four groups in accordance with lining technique: control (one adhesive layer), three adhesive layers individually photo… Show more

“…Although several studies 1,11,13,17,19,[22][23][24] have pointed out the benefits of the modulated photoactivation, this issue has not yet been completely established as successful. One of the reasons is because composites behave differently when subjected to modulated photoactivation.…”

“…Low light intensity or modulated curing methods reduce the polymerization rate of composites, consequently reducing the stress rate generated 11,12 and improving the marginal adaptation of composite restoratives. 13 In this sense, modulated curing methods such as soft-start (SS) and pulse delay (PD) have been proposed. 7,[14][15][16] Yoshikawa and others 17 reported that the SS curing method promotes better marginal sealing of cavo-surface margins of composite restoratives.…”

“…Pulse-delay uses a short, low-level burst, a delay for polishing and finally a long exposure at full intensity. 7 While many laboratory reports suggest that SS polymerization may be beneficial, 1,3,[8][9][10][11][12][13] other studies have found either no difference or a negative influence on various physical parameters. [14][15][16][17][18][19][20][21] Several studies concluded that some of the restorative techniques, which aim at stress reduction, have limited applicability and depend on the materials employed.…”

“…[9][10][11][12][13][14] However, the advantage of this technique has not been demonstrated, and some researchers reported no added advantage with this technique. [15][16][17][18][19] The elastic modulus of the base material might significantly affect the integrity of the overlying filling material.…”
