Abstract


Background: The treatment of discolored teeth bleaching method , simple operation , without molars , and will not damage the appearance of the tooth itself . Endless variety of bleach on the market , and continue to improve technically . Since 1989 Haywood will carbamide peroxide preparations used in night- home bleaching technique , bleaching technology can be widely developed . Over the past decade , clinics, favored by more and more people beauty bleach its fast and secure advantage . Been bleaching efficacy and safety issues by the concern of scholars and clinicians , the results are not the same . BEYOND cold light teeth bleaching is the rise in recent years as a consulting room bleaching method . But no bleach enamel effect reported in the literature search . Simulate the clinical application of the experiment with extracted teeth to simulate the clinical application Objective: In this study, using in vitro tooth observed the BEYOND Teeth bleaching system away from extracted teeth bleached enamel surface structure and microhardness change and its clinical application when the tooth enamel surface . Methods: 22 orthodontic tooth extraction in the past three months , remove the root will be divided into two halves buccolingual crown as the experimental group and control group , the experimental group the BEYOND Teeth bleaching system simulation clinical bleach , lingual as the control group . Randomly selected 20 teeth , buccal and lingual tooth enamel surface microhardness test digital micro hardness tester , the remaining two teeth in the scanning electron microscope buccal and lingual tooth enamel surface structure , comparing buccal and lingual side of the tooth surface structure and microhardness values ??change . Results: 1 . Microhardness test: the experimental group block enamel surface microhardness of 292.4 ± 43.
