Abstract

Purpose: The purpose of this study was to evaluate microleakage around Class V resin composite restorations with different cavity configurations, bonded with one of seven self-etching materials or with an adhesive using the total-etch technique. Materials and Methods: Ninety-six human molars and premolars were randomly assigned to eight groups and bonded with one of seven self-etching adhesives—Prompt-L-Pop™ (3M ESPE, St. Paul, MN, USA), Adper Prompt-L-Pop™ (3M ESPE), Clearfil SE Bond® (Kuraray Medical, Okayama, Japan), Prime & Bond® NT/NRC (Dentsply DeTrey, Konstanz, Germany), Xeno® III (Dentsply DeTrey), One-Up Bond® (Tokuyama Dental, Tokuyama, Japan), AdheSE® (Ivoclar Vivadent, Schaan, Liechtenstein)—or with Prime & Bond® NT (Dentsply DeTrey) using a separate total-etch technique. Cavities were cut in both the lingual and buccal surfaces and were approximately 3 mm mesiodistally, 1.5 mm deep, and 2.0 mm occlusogingivally. Selected at random, box-shaped cavities were cut on one side and V-shaped cavities were cut on the contralateral side. After bonding, the cavities were incrementally filled with a microhybrid composite (Tetric Ceram®, Ivoclar Vivadent), cured, and immediately polished with Sof-Lex™ (3M ESPE) disks. The teeth were thermocycled, and the specimens were examined for microleakage using Procion Brilliant Red® (ICI, Slough, UK) as a marker. Results: Comparisons of both gingival and enamel margins within each of the groups showed no significant difference owing to configuration factor (C-factor; p < .5 in all cases, calculated with Kruskal-Wallis nonparametric analysis of variance [ANOVA]) and Dunn's multiple comparison test). All groups showed microleakage at the gingival margins irrespective of C-factor or bonding agent (box-shaped cavities, p < =.8862; V-shaped cavities, p < =.9623; using the ANOVA). Microleakage was not observed at all enamel margins regardless of C-factor or bonding agent, and there were no significant differences between the groups (box-shaped cavities, p < =.9869; V-shaped cavities, p < =.9550; using the Kruskal-Wallis nonparametric ANOVA).
