Comparing the effect of fluoride containing remineralizing agents and Er: YAG laser on enamel Demineralization and surface microhardness around Orthodontic Brackets (An In vitro study)

Abstract

The formation of white spot lesions, or enamel demineralization, around fixed orthodontic attachments is a common complication during and following fixed orthodontic treatment, which marks the result of a successfully completed case. Preventive programs must be emphasized to all orthodontic patients which include - Educating and motivating the patients for excellent oral hygiene practice - Enhancing the enamel resistance using topical fluoride and additional new methods as using dental laser.

 Aim of the Study:

The aim of this in vitro study was to:

• Compare the effects of fluoride varnish with added tricalcium phosphate (TCP), fluoride varnish with calcium fluoride (CaF2) and Er: YAG laser irradiation on: 1- Enamel demineralization around orthodontic brackets histologically.

2- Microhardness change of enamel around orthodontic brackets.
