Title

ASSESSMENT OF MICROSHEAR BOND STRENGTH: SELF-ETCHING SEALANT VERSUS CONVENTIONAL SEALANT

Pages

  137-142

Abstract

 Objective: Recently, self-etching fissure sealants have been introduced to reduce technical sensitivity; however, their efficacy should be assessed. The aim of this study was to assess of the microshear BOND STRENGTH of self-etching and conventional fissure sealants.Materials and Methods: Thirty non-carious third molars were randomly divided into three groups (N=10). Microcylinders of Concise fissure sealant were bonded to pre-pared buccal and lingual surfaces using the two following procedures. In the first group, phosphoric acid was used to prepare the substrate; whereas in group two, Concise was used in combination with Prompt L-Pop. In group 3, a self-etching fissure sealant (Enamel Loc) was utilized per se. After 24 hours, the samples were subjected to 500 rounds of thermo cycling and shear bond testing using a microtensile tester ma-chine with a crosshead speed of 0.5mm/min. Data were analyzed using one-way re-peated measure ANOVA and Bonferroni Post HOC tests (SPSS version 16).Results: The mean and standard deviation of microshear BOND STRENGTH of the groups were as follows: Group 1: Concise+etching (14.59±1.19 MPa), Group 2: Concise+Prompt L-Pop (12.86±1.98 MPa), and Group 3: Enamel Loc (5.59±0.72 MPa). One-way ANOVA revealed that all the differences were significant and the conventional sealant exhibited the highest mean BOND STRENGTH.Conclusion: Conventional sealant using phosphoric acid etch application prior to fis-sure sealant application demonstrated more BOND STRENGTH in comparison with that of self- etch bonding and self- etch sealant.
