Aim The aim of the present study was to compare the effects of carbon dioxide (CO2) laser and casein phosphopeptide amorphous calcium phosphate (CPP‐ACP)fluoride varnish on enamel demineralization. Methods Human teeth were randomly assigned to three groups. The enamel was treated with fluoride varnish, 10.6 μm CO2 laser, or no treatment (control), followed by 9 days of pH cycling. Baseline and final FluoreCam images were used to quantify the area, intensity, and impact of demineralization; cross‐sectional microhardness was used to measure the mechanical properties of the enamel. Results There were statistically‐significant changes in the area, intensity and impact of demineralization in the control and laser groups (P < 0.05), but not in the fluoride group. The control group showed a significantly greater area and impact of enamel demineralization compared to the fluoride group. The area of demineralization in the laser group was significantly greater than that of the fluoride group. Enamel demineralization of the laser and control groups was comparable. The fluoride group showed statistically‐significant harder enamel than the control at 20, 40, and 60 μm depths; the laser group enamel was significantly harder than the control at 20 and 40 μm depths. The fluoride group showed statistically‐significant harder enamel than the laser group at 20 μm depth. Conclusions CPP‐ACP fluoride varnish is more effective than CO2 in preventing enamel demineralization.

“…Laser irradiation has been widely studied in vitro and showed its effectiveness in increasing enamel resistance to decalcification, suggesting that it could be useful during orthodontic treatment. As presented in the literature, many laser types have been used to prevent enamel demineralization around orthodontic appliances, including Er:YAG, [23][24][25] Nd:YAG, 13,21,22 CO 2 , [18][19][20][21][22][26][27][28] diode, 29,30 and argon laser. [14][15][16][17]31,32 Although the clinical application of lasers during orthodontic treatment for a preventive purpose is still limited, the present review showed clinical effectiveness of laser irradiation in inhibiting enamel demineralization.…”

The objective of this study was to investigate the in vivo effectiveness of laser in the prevention of enamel demineralization during orthodontic treatment. A search of electronic databases (PubMed, ScienceDirect, Google Scholar, Scopus, the Cochrane Central Register of Controlled Trials-CENTRAL, OpenGrey, and ProQuest Dissertations and Theses-PQDT Open from ProQuest) was carried out. In vivo studies, randomized and/or controlled clinical trials regarding the use of laser treatment to prevent enamel demineralization during orthodontic treatment were included. The risk of bias of the studies included was assessed independently by 2 authors according to Cochrane guidelines. Eight articles were identified, comprising a total of 183 patients. Significant differences were observed in enamel demineralization between laser-irradiated and control groups for all laser types: argon laser, CO 2 laser, neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, and Optodan ® laser, except for argon laser application for curing bracket adhesives, where no statistically significant differences were noted. Laser irradiation may be effective in inhibiting demineralization during orthodontic treatment, but there is a need for further randomized, controlled clinical trials, utilizing different laser systems to determine real clinical efficacy of the technique.

Introduction: This study aimed to assess the effects of CO2 and erbium-doped yttrium aluminum garnet (Er:YAG) lasers with and without fluoride varnish on demineralization around composite restorations. Methods: This in vitro experimental study evaluated 96 extracted human premolars. After preparation and restoration of class V cavities in the buccal surface of the teeth with composite resin, they were randomly divided into 8 groups of control, CO2 laser (L1), CO2 laser-NaF (L1F), NaF-CO2 laser (FL1), Er:YAG laser (L2), Er:YAG laser-NaF (L2F), NaF-Er:YAG laser (FL2) and NaF (F). The entire surface of the teeth, except for the restored cavity in the buccal surface and 1 mm around the margin, was coated with two layers of nail varnish. The teeth then underwent pH cycling for 10 days (3 hours in demineralizing solution and 21 hours in remineralizing solution) to artificially induce demineralization. The amount of calcium and phosphorous released into the cariogenic solution was quantified using atomic absorption spectroscopy and spectrophotometry. The Vickers hardness tester was used to measure the hardness of the tooth structure adjacent to composite restoration. Data were analyzed using one-way ANOVA and Tukey's test. Results: The four groups of L1F, FL1, FL2 and L2F showed minimum loss of calcium and phosphorous ions, and the mean hardness of FL1 and FL2 groups was higher than that of other groups. Conclusion:The CO2 and Er:YAG lasers alone have no significant effect on the resistance of tooth structure to cariogenic solution. However, they can exert a synergistic effect when used along with NaF varnish. Fluoride varnish applied prior to laser irradiation confers further resistance to the tooth structure and positively affects its hardness.
