Effect of Fluoridated and Non-Fluoridated Bleaching Agents on Enamel Microhardness: An in Vitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 2
Abstract
The aim of this study was to investigate the effect of fluoridated and non-fluoridated carbamide peroxide gel on enamel microhardness (Vickers hardness number).60 extracted human premolar teeth were selected. Teeth were divided into 3 groups. Group A- Control (no bleaching), Group B- (non-fluoridated bleaching agent) group C (fluoridated bleaching agent). All specimen were bleached for 21 days with the respective bleaching agents for 4 hours. Microhardness testing was done on baseline (prior to bleaching) and on 21st day (post bleaching).Statistical analysis was done by paired t test, and (0.01) is considered as level of significance. After bleaching all samples group B showed decrease in micro-hardness, while microhardness was increased in group C. Enamel microhardness is reduced after bleaching with 16% CP gel, but fluoridated bleaching agent increased the enamel microhardness.
