The Impact of Fluoride or Ozone Gas Before Vital Tooth Bleaching on Enamel Surface Roughness

Purpose: The aim of this in vitro study was to investigate the efficiency of fluoride or ozone as a preventive for reducing the negative consequences of the vital bleaching on enamel surface. Material and Methods: 30 freshly extracted caries-free human incisors were divided into the following three groups (n=10): Group 1; treatment with 38% hydrogen peroxide (HP) as a control; Group 2, treatment with HP following a fluoride application; Group 3, treatment with HP following a ozone gas therapy. Surface roughness values were measured by profilometer. Results: In this study, the lowest surface roughness was in Group 2 (0,37 μm), Group 3 (0,57 μm) was showed the highest surface roughness values . In terms of surface roughness values, there was no statistically significant difference between Group 1 (control) and Group 3 (p 0.05). Conclusion: Fluoride application as a preventive before treatment of vital bleaching was reduced the surface roughness of the enamel.
