Comparative Evaluation of Effect of mode of application of Fluoride on Bleached enamel microhardness: An in vitro study
Journal Title: Scholars Journal of Dental Sciences - Year 2017, Vol 4, Issue 9
Abstract
The aim of this study was to investigate the effect of application of fluoride externally and within the bleaching agent on enamel microhardness. 30 extracted human premolar teeth were selected. Teeth were divided into 3 groups. Group A- (16% CP bleaching agent) group B (fluoride containing bleaching agent) group C (application of fluoride on bleached enamel). All specimen were bleached for 21 days with the specific bleaching agents for 4 hours. Fluoride application (APF gel) was done for Group C after bleaching. Microhardness testing was done on baseline (prior to bleaching) and on 21st day (post bleaching) and post fluoride application. Enamel microhardness is reduced after bleaching with 16% CP gel, but addition of fluorides to the bleaching agent or applied externally after bleaching helps to restore the microhardness.
