Abstract
Background: One of the serious side effects of fixed orthodontic appliances is the development of white spot lesions.
Aim: The aim of this study was to evaluate the in vivo effects of three topical protecting agents on enamel demineralization around orthodontic brackets at two time intervals.
Material and methods: Twenty-eight patients, 13-16 years (mean: 14.06 +/- 1.73 years), scheduled to have four first premolar teeth extracted, were divided into four groups: three experimental and one control. SeLECT-DefenseTM, (Lubbock, TX, USA), Clinpro fissure sealant (3M ESPE-USA) and White Varnish with TCP (3M ESPE-USA) were applied to tooth surfaces around brackets in the experimental groups. After one month, two premolars of each patient; (14 premolars from each group) were extracted. The teeth were stored in a refrigerator in flasks containing gauze dampened with saline. After two months, the other fourteen premolars form each group were extracted and treated similarly. Demineralization of enamel around the brackets was evaluated by a cross- sectional microhardness method with an indentation at two positions (occlusal-cervical), 10μm depth.
Results: There was no significant difference between the microhardness of either the occlusal or the cervical halves in the two times tested. Statistically significant differences were determined between each of the treatment and control groups (p <0.001). However, no statistically significant differences were detected between the experimental groups (p <0.05).
Conclusion: The findings from the present study highlight the value of the usage of any of the three protecting agents to decrease demineralization around orthodontic brackets.
