Abstract

Introduction: Various methods have been recommended to treat dentin sensitivity, including Laser therapy and CPP-ACP (Casein phosphopeptide-amorphous calcium phosphate). The aim of this study was to compare the effect of high-power Diode laser 980 nm and CPP-ACP paste on the dentin hypersensitivity treatment (DH).
Materials and Methods: In this single-blind clinical trial study, 96 dentin-sensitive teeth were randomly divided into three groups of 32, and the groups were treated with Diode 980 nm laser, power 1 watt,30 seconds irridation, CPP-ACP paste and control group (guide radiation without laser irradiation). The level of sensitivity and pain were determined and compared before treatment, 15 minutes after the first and second sessions, one week, one month, and two months after the end of treatment. The data were evaluated with one-way variance statistical tests and Tukey's post hoc test (α = 0.05).
Results: There was no significant difference between the groups in the average score of DH except for the eighth week. (P>0.05) In the eighth week, the average score of DH in the diode laser group (p value = 0.04) and paste containing CPP ACP (p value > 0.001) was significantly lower than the control group. However, there was no significant difference between these two test groups (p value = 0.18). Changes in the average of DH in the eighth week showed that in the pasted group containing CPP-ACP, reduced pain was more than the laser-treated group (p value = 0.046) and in the laser group it was more than the control group (p value = 0.01).
Conclusion: Both treatments effectively reduced dentin sensitivity after two months, but there is no significant difference between high-power Diode laser 980 and CPP-ACP paste in the treatment of dentinal hypersensitivity.
