Abstract
CENGİZ A.K., The effect of cleaning methods on the bond strength of saliva contaminated high translucent zirconia. Hacettepe University, Faculty of Dentistry, Thesis in Prosthodontics, Ankara, 2022. The aim of this in vitro study was to evaluate the effect of different celaning methods on the shear bond strength of the saliva contaminated zirconia. The 120 zirconia specimens (7x7x3 mm) were fabricated and abraded with aluminum oxide. Specimens were divided into 8 groups (n=15). Group MDP were first treated with one coat of MDP primer, after then a thin coat of fresh human saliva was painted specimens. Except the control group; all specimens were contaminated saliva like MDP group’s procedure. The specimens were cleaned with Ivoclean solution, concentration of 5.25% NaOCI solution, %1 phytic acid solution, 37% phosphoric gel, air-water spray and Al2O3 additional air-abrasion. Self-adhesive resin cement was applied to all samples with the help of a standard kit. The bond strengths were measured by shear testing after thermal cycling at 5-55 C. (TC 5000) The specimen surfaces were evaluated under stereomicroscope and randomize 1 specimen of the each group was examined by SEM and EDS. Statistical evaluation of the results was made by Kruskal-wallis and Bonferroni analyzes. While air-water spray, phytic acid and phosphoric acid groups showed statistically significantly lower SBS values compared to the control group (p<0.05), no statistically significant difference was found between the Ivoclean, MDP primer, 5.25% NaOCI and Al2O3 groups with the control group. According to the EDS evaluation, phosphorus element in the phosphoric acid group, and carbon element in the phytic acid and air-water spray groups were found at higher concentrations compared to the control group. In this study, primer application containing MDP, Ivoclean paste, 5.25% NaOCI and additional blasting methods before saliva contamination were found to be successful in removing saliva contamination and obtaining high SBS values.
