Chlorhexidine Effect on Color of Treated White Spot Lesion with Remineralization Materials (Fluoride Varnish, Tooth Mousse)


Background the white spot lesions represent subsurface enamel demineralization, manifested as white opacities which considered as esthetic problem. Objectives to evaluate the color improvement of white spot lesions and stability against discoloration following, fluoride varnish, tooth mousse treatments with immersion in chlorhexidine.Materials and Methods artificial white spot lesions created on the gingival third of buccal surface of premolar tooth (N=90) using demineralization solution; PH (4-4.5) at room temperature for 4 weeks, specimens were treated with fluoride varnish, tooth mousse and untreated group (control). Groups were immersed in chlorhexidine for 1 hour. Color change was measured with vita easy shade device at baseline, after white spot lesions formation, after treatment and after immersion in chlorhexidine. Results the mean of color change in deionized distilled water and chlorhexidine increased after formation of white spot lesions then decreased with the application of fluoride varnish and tooth mousse, there was a significant difference between the white spot lesions, fluoride and Mousse group in deionized distilled water and chlorhexidine, there was non-significant effect of chlorhexidine on color of white spot lesions treated with fluoride varnish. Conclusion the fluoride varnish and tooth mousse could return mineral to subsurface enamel of white spot lesions and might improve esthetics and color stability when the use of chlorhexidine with tooth mousse.
