Influence of several materials on the bond strength of glass polyalkenoate to dentin
Khalid A. Al Wazzar *, BDS, MSc
Glass ionomer (Gl) is a restorative that bonds to dentin by molecular adhesion. During a dental treatment, several adjunctive materials such as temporary fillings, cements and Intracanal medicaments may be used prior to the placement of Gl which might adversely influence its adhesion to dentin. The purpose of this study was to determine the influence of using eugenol containing and eugenol free zinc oxide temporary cements, calcium hydroxkleand Iodine potassium Iodide Intracanal medicaments, and Epoxy resin sealers on the adhesion of Ketac-Silver Apllcap, to dentin. Sixty dentin specimens were prepared and divided to six groups. Each of the five groups was treated with one of the adjunctive materials for one week. The adjunctive material was removed and dentin cleaned with pumice-water slurry, etched, rinsed thoroughly and dried with air. Ketac-silver short cylinders were formed on the dentin between two sliding surface; a specially designed testing apparatus. The two sliding surfaces were pulled apart using a testing machine and the debonding force was recorded. One-way analysis of variance and Tukey's multiple range test were used to analyze thedata. while the debondlng force was 2.2MPa for the control, it was 2.03, 2.09, 2.00, and 2.l6MP for specimens subjected to four of the adjunctive materials and there were no statistically significant differences (P< 0.05). The only adjunctive material that caused significant difference in the bond strength between Ketac-Sllver and dentin (an improvement) was epoxy resin sealer (AH-26) yielding a debonding value of 3.50Mpa.
