Abstract

Purpose: The current study was conducted to clinically assess the efficacy of concomitant application of Diode Laser with different remineralizing materials (Remin Pro, X Pur Remin, and Pro-fluoride varnish) on white spot lesions. Materials and methods: A single-blinded, parallel-group, randomized clinical trial design was followed. Forty-five teeth with white spot lesions (WSLs) were selected from 30 patients who attended the outpatient clinic of the Operative Dentistry department, Faculty of Dental Medicine for Girls, Al-Azhar University, Cairo, Egypt. The participants were randomly assigned into three groups according to the applied treatment agent: Remin Pro, X Pur Remin, and Pro-fluoride varnish. Treatments in all groups were combined with diode laser application (801 nm,1W, continuous mode). The color changes of WSLs were evaluated before application (T1), immediately (T2), and after one month (T3) by using an Easy shade V spectrophotometer. Results: Mann-Whitney’s test revealed statistically significant differences between the experimental groups at all-time intervals (sound tooth was significantly higher than white spot lesion). Remin Pro was significantly the highest at T2-T3 and T1-T3. There was none statistically significant difference between X Pur Remin and Pro-fluoride varnish for the sound tooth. Conversely, at T2-T3 and T1-T3 Pro-fluoride, the varnish group showed the highest statistically significant difference. There was none statistically significant difference between Remin Pro and X Pur Remin in white spot lesions. Conclusion: Diode laser irradiation (801 nm,1W, continuous mode) can improve in terms of the color change of white spot lesions of enamel.
