[Scanning electron microscopy study on different orthodontic methods of using fluoride in enamel white spot
Abstract
Objective:
To determine which method of topical fluoride application could make the enamel uptake more fluoride.
Methods:
12 extracted human premolars were divided into three groups of 4 teeth each: Group 1, control and not applying fluoride; Group 2, applying fluoride during etching; Group 3, applying fluoride after etching. In each group, the teeth were treated with etching and fluoride respectively. The specimens were then examined with scanning electron microscopy.
Results:
The results showed that there were more reaction products on the enamel surface of Group 3.
Conclusion:
There was more fluoride uptake into the enamel treated with fluoride after etching.
