Microleakage of Composite Inlays Luted with Self-adhesive Cements

Objective: To evaluate the microleakage of three self-adhesive cements and one etch & rinse resin cement on dentin and enamel interfaces. Methods: Forty-eight inlays preparations (n=12) with enamel and dentin margins were performed on extracted teeth. After impressions, indirect composite inlays were manufactured and luted with self-adhesive resin cements (RelyX U100, Maxcem or SpeedCem) or an etch & rinse resin cement (Nexus 3). Restored teeth were thermocycled and immersed in a silver nitrate solution. Specimens were cut through restorations, surfaces were photographed and microleakage was measured with aid of computer software (Image J). Statistical analysis was realized with KruskalWallis nonparametric test (P<0.05). Results: Statistical analysis of enamel-cement interfaces showed that Nexus provided better marginal sealing than Speedcem (p<0.05). Considering dentin-cement interface, RelyX U100 presented the smaller microleakage degree than Speedcem and Maxcem (p<0.05). Conclusions: Among self-adhesive resin cements, RelyX U100 showed better sealing ability of enamel and dentin margins and its performance was comparable to Nexus 3. *Corresponding author: Diogo Pedrollo Lise, Departamento de Odontologia, Disciplina de Dentística, Sala 138, Universidade Federal de Santa Catarina, Campus Universitário-Trindade, CEP 88040-970, Florianópolis, Santa Catarina, Brazil, Tel: +55 48 37219880; Fax: +55 48 37219880; E-mail: [email protected] Received February 11, 2014; Accepted March 03, 2014; Published March 05, 2014 Citation: Lise DP, Lopes GC, Maia HP, Baratieri LN (2014) Microleakage of Composite Inlays Luted with Self-adhesive Cements.
