Title

MICROLEAKAGE OF THREE TYPES OF GLASS IONOMER CEMENT RESTORATIONS: EFFECT OF CPP-ACP PASTE TOOTH PRETREATMENT

Pages

  182-188

Abstract

 Statement of the Problem: Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) increases the mineral content of tooth structure. This may enhance the chemical bonding of GLASS IONOMER CEMENTs (GIC) and marginal sealing of their restorations.Purpose: The aim of this study was to evaluate the effect of CPP-ACP paste pretreatment on the MICROLEAKAGE of three types of GIC.Materials and Method: In this study, 72 Class V cavities were prepared on the buccal and lingual surfaces of molars with occlusal margins in enamel and gingival margins in root. The cavities were divided into 6 groups. Cavities in group 1 and 2 were restored with Fuji II, group 3 and 4 with Fuji II LC, and group 5 and 6 with Ketac N100 with respect to the manufacturers’ instructions. In groups 2, 4 and 6, CPP-ACP containing paste (MI paste) was placed into the cavities for 3 minutes before being filled with GIC. The teeth were thermocycled, stained with dye, sectioned, and scored for MICROLEAKAGE under stereomicroscope. Kruskall-Wallis and Chi-Square tests were used to analyze the data.Result: There were no statistically significant differences between the control and the CPP-ACP pretreatment groups in enamel and dentin margins. In pairwise comparisons, there were no significant differences between the control and the experimental groups in enamel margin, and in dentin margins of G1 and 2, G5 and 6; however, a significant differences was detected in dentin margins between G3 and 4 (p= 0.041).Conclusion: CPP-ACP paste pretreatment did not affect the MICROLEAKAGE of Fuji II and Ketac N100 in enamel or dentin, but decreased the MICROLEAKAGE in dentine margins of Fuji II LC when cavity conditioner was applied before surface treatment.
