ABSTRACT
BACKGROUND: The aim of this longitudinal study is to verify changes in the oral health-related quality of life of patients 180 days after treatment of dentin hypersensitivity (DH) with laser and cyanoacrylate. METHODS: This clinical, controlled, randomized, double-masked trial used a split-mouth design, and quadrants were randomized to receive either laser or cyanoacrylate treatments. All patients received both treatments. The study included 62 patients aged 12 to 60 years (mean: 31.4 years) in whom a total of 432 teeth were treated. Quadrants were randomly distributed into two groups: cyanoacrylate (n = 218 teeth) or laser (n = 216 teeth) treatment. DH was evaluated with air and cold stimuli at 24 hours, 30, 90, and 180 days after treatment. The Oral Health Impact Profile (OHIP-14) questionnaire was applied at baseline and 180 days after treatment. RESULTS: There were statistically significant differences in the following OHIP-14 subscales before and after treatment: physical pain (P = 0.002), psychologic discomfort (P <0.001), psychologic disability (P = 0.003), social disability (P = 0.01), and total score (P <0.001). At the end of the study, 80.6% of participants reported an improvement in their condition. CONCLUSION: There was a reduction in the impact of DH on the quality of life of study participants after interventions with laser and cyanoacrylate.
