The Effect of WHITE-CLASS Material on Enamel Calssification Using Diagnodent (Clinical Study)

Abstract

Background: With the widespread use of in-home bleaching , multiple commercial materials were spread for this purpose. Each one of those materials is different from the others used in in home bleaching which are composed  of hydrogen peroxide combined with other materials to improve the properties and increase the duration of effectiveness of bleaching , so we carbamide peroxide 22% gives only 7% of the active substance (hydrogen peroxide). This is why we have to study the effect of these materials on the calcification of dental enamel, comparing among anterior teeth calcification by the type and location in each jaw.

Aim of study: Evaluation of the effect of FGM white class 7.5% on enamel calcification directly and after six months, and to compare among the six anterior teeth in upper & lower jaws.

Materials and Methods: FGM White -class (hp) 7.5% was applied on the six front upper and lower teeth (from canine to canine) for 5 patients so that the full size of the sample was 60 anterior teeth, the calcification of studied teeth was measured before, after one day of bleaching and 6 months later using DIAGNODENT device (normal calcification values ranging from 0-7 (0 is full calcification, 7 is severe lack of calcification)).

Results: There was no negative effects of white class bleaching material on enamel calcification. No differences of calcification among studied teeth nor between upper & lower jaws were detected.

Conclusions: FGM-White class with a 7.5% is safe if used as in home bleaching material.
