Microtensile Bond Strength of Three Different Adhesive Systems to Primary Enamel: An In Vitro Study.

Purpose:The purpose of this in vitro study was to assess and compare the mircotensile bond strength of three adhesive systems to primary enamel. Methods: The laboratory study involved the preparation of 16 primary molars, randomly distributed over three groups, using the following adhesive systems: Gi-Prime&Bond XP (PBXP); Gil-Clearfil SE Protect Bond (CSEB); and Gill-Clearfil S3Band Plus (CSB). After applying each adhesive system on enamel as recommended, CeramX Universal composite blocks were built. Samples were then cross-sectioned into quadrangular test specimens and subjected to microtensile tests. Fracture patterns were classified by optical microscopy examination. Statistical analysis was performed using IBM SPSS 24.0 software (five percent significance level). [ABSTRACT FROM AUTHOR]
