Abstract:
Background: This randomized single‑blinded clinical trial aimed to evaluate the effectiveness of
diode laser and fluoride in the treatment of dentin hypersensitivity (DH) due to gingival recession.
Materials and Methods: Twenty‑eight individuals randomly distributed across three groups
participated: 10 individuals who were treated with diode laser, nine who were treated with fluoride, and nine
who received placebo. Pain was assessed with the Visual analog scale (VAS). Evaporative stimulus and tactile
stimulus were evaluated with the verbal rating scale (VRS). VAS was applied shortly after, 6 h after, 12 h after,
and 24 h after the single‑session treatment for DH, whereas VRS was applied shortly after, 15 min and 7 days
after the treatment. Participants’ quality of life was assessed with the validated Brazilian version of the Dentine
Hypersensitivity Experience Questionnaire assessing functional limitations, coping behaviors, emotional, and
social impacts caused by DH. Descriptive statistics and the ANOVA test were used. Values of P < 0.05 were
statistically significant. Results: Diode laser significantly reduced the DH to the evaporative stimulus (P = 0.002).
The application of fluoride did not change the degree of DH to evaporative and tactile stimuli (P > 0.05). The group
of individuals who were treated with diode laser presented a higher reduction in DH (25.4%) when compared to
the group of individuals treated with fluoride (17.1%), and the group of individuals among whom placebo had
been used (2.9%). Descriptive analysis indicated that the items measuring the emotional and social impacts
of DH were those with a more negative impact on the individuals. Conclusion: Therapy with diode laser was
more effective in reducing DH than therapy with fluoride.
