Title

EFFECT OF COMBINED APPLICATION OF HIGH- AND LOW-INTENSITY LASERS ON DENTIN HYPERSENSITIVITY: A RANDOMIZED CLINICAL TRIAL

Pages

  55-49

Abstract

 Background: DIODE LASERs (DLs) have demonstrated equal or better DESENSITIZING EFFECTs than fluoride varnish, 10% potas-sium nitrate (NK) gel and Gluma. The current study evaluated the DESENSITIZING EFFECT of combined application of DLs with two different output powers and compared it with single DL therapy.Methods: Sixty-two hypersensitive teeth were allocated randomly into two groups: the single group was treated with 3-W DL beam once and in the combined group, the teeth were irradiated three times (the first time with 0.2-W and then with 3-W and the second and third times, 48 and 96 hours after the baseline visit, with 0.2-W DL beams). The amount of dentin hyper-sensitivity (DH) was evaluated, immediately before and after each visit, and 1 week and 1 and 3 months after the first visit. Data analysis was performed using chi-squared test, repeated measurement of ANOVA and Mann-Whitney U test. P<0.05 was considered statistically significant.Results: Statistically significant changes were observed in the means of VAS indices between all the measurement intervals and pretreatment measures, in both experimental groups (P<0.001). The difference in VAS reduction among the groups was not significant when the hypersensitive teeth were stimulated by a periodontal probe and a jet of air (P=0.63 and P=0.12).Conclusion: The results of the present study showed that using both high-intensity and combined DL beams gives rise to significant reductions in DH. There was no significant difference between combined and single laser therapies in the treatment of tooth hypersensitivity.
