Effect of Pre-heated Composites and Flowable Liners on Class II Gingival Margin Gap Formation

Abstract

Clinical RelevanceThe use of reduced viscosity composites, such as flowable and pre-heated resins, as the first increment in Class II preparations, did not improve gingival margin adaptation nor did it minimize gap formation at the dentin-composite interface.

Effect of configuration factor on gap formation in hybrid composite resin, low‐shrinkage composite resin and resin‐modified glass ionomer

“…Mechanical features of the silorane‐based composite resin were shown to be comparable to clinically successful methacrylate‐based composite materials, and this resin composite showed better characteristics than the methacrylate‐based composites in setting contraction and marginal adaptation . The microleakage of experimental silorane‐based composite resin was less than commercial methacrylate‐based composites in mesio occluso distal cavities . In order to decrease microleakage problems, silorane‐based materials might be a better replacement for methacrylate‐based composites .…”

“…15 The microleakage of experimental silorane-based composite resin was less than commercial methacrylate-based composites in mesio occluso distal cavities. 16 In order to decrease microleakage problems, silorane-based materials might be a better replacement for methacrylate-based composites. 13 In a clinical study, silorane-based composite showed good durability, but not considerably better than the methacrylate-based composites in class II cavities.…”

Comparison of Microleakage and Thickness of Resin Cement in Ceramic Inlays with Various Temperatures

“…3,5,6,21 Daronch et al 22 found no significant difference between the microleakage of warmed composite resin at 140°F, room temperature composite resin and flowable composite resin except for enamel margin of class V cavities; at room temperature composite resin microleakage was less than that of flowable composite resin. …”

“…Many studies have investigated the effect of temperature on microleakage of direct composite resin restorations, 4-6 but none of them paid attention to the effect of different temperatures of ceramic inlays on microleakage of room-temperature resin cement. …”

Influence of preheating the bonding agent of a conventional three-step adhesive system and the light activated resin cement on dentin bond strength

“…[13591617181920212223] The energy generated by preheating the composite increases the rate of collisions between the nonreactive groups and the free radicals, resulting in a more complete polymerization reaction. [2316171824] Reis et al .,[12] observed an increase in bond strength at the tooth/resin interface when heated adhesives were used.…”
