The Influence of Remineralization after Bleaching - In Vitro Study
Journal Title: Scholars Journal of Dental Sciences - Year 2016, Vol 3, Issue 11
Abstract
Abstract: The aim of this study is to compare remineralizing agent applications on micro-hardness of bleached teeth using Vicker’s Hardness profiles. 60 extracted human premolar teeth were selected. Teeth were divided into 3 groups. Group A- Control (16% CP), Group B- (16% CP + CPP- ACP), Group C- (16% CP + APF). All specimen were bleached for 15 days with 16% carbamide peroxide for 4 hours. On 15th day remineralizing agent application was done with respective agents for 5 minutes. Microhardness testing was done on baseline (prior to bleaching), on 15th day (post bleaching), on 30th day (post remineralizing agent application). Statistical analysis was done by descriptive and inferential statistics using Student’s paired t test, one way ANOVA and Multiple Comparison: Tukey Test and software used in the analysis was SPSS 21.0 version and ( P<0.05) is considered as level of significance. After bleaching all samples from all the groups showed decrease in micro-hardness. Further application of APF & CPP- ACP showed reversal of microhardness to the baseline and more than baseline values. APF & CPP – ACP both are equally efficient in regaining the microhardness of teeth. Keywords: Bleaching, Remineralization, CPP- ACP, APF
