Clinical Efficacy of Diode Laser on Dentin Hypersensitivity: Preliminary Results
Objectives: The objective of the present randomized, parallel-type controlled interventional study is the evaluation of the effectiveness of 980 nm diode laser irradiation (DClase 980nm, DC international, Jupiter, FL, USA), associated or not with fluoride varnish, over clinically exposed dentin in the control of Dentin Hypersensitivity (DH) in the short and long-term.
Methods: Sixty patients (Ethics Committee n. 49808715.5.0000.5417) with gingival recession and dentinal sensitivity complain after evaporative stimulation were selected and randomly treated according to the different protocols (irradiation with 1W diode laser (DL), application of fluoride varnish (FV), and association of 1W diode laser + fluoride varnish (LV). The diode laser was irradiated perpendicularly over the exposed roots, scanning the entire surface in contact mode (10Hz, 1000mW) with a controlled velocity in order to standardize the energy density (99,17/cm2). The assessments of DH were performed through the visual analogue scale (VAS), prior to treatment, immediately thereafter, as well as 1 week, 1 and 6 months after treatment
Results: The preliminary results involved the DH score of 2 patients for each group, analyzed prior, immediately and 1 week after treatments. The results for DL, FV and LV groups were respectively: DL– 2.9 / 0.25 / 0.55; FV- 5.85 / 2.05 / 3.4; LV- 5.25 / 3.4 / 4.55. One-way ANOVA repeated measures indicates no significant differences between the VAS scores at the different evaluation times for all tested groups until now.
Conclusions: The results showed that all treatments showed a tendency to immediate decrease in HD intensity, but a slight tendency to relapse after 1 week also could be noted.
