Resumo
Objective: The aim of the present study was to determine how long the effects of laser
and cyanoacrylate last when used as treatments for dentine hypersensitivity (DH). In
addition, the predictive factors of DH recurrence and the prevalence of DH according
to type of tooth were investigated.
Materials and methods: Sixty-two patients contributed with 434 sensitive teeth. Two
hundred sixteen teeth were randomized to receive laser treatment (wavelength of 795
nm) and 218 received cyanoacrylate treatment. Both treatments were applied three times
at intervals of 48 hours. Dentine hypersensitivity was assessed by air stimulus at baseline
and 1, 30, 90 and 180 days after treatment by a blinded researcher. Additionally, possible etiologic factors were assessed. The data were analyzed by Kaplan-Meier survival
curves and by logistic regression.
Results: Both groups had signifi cant reductions in DH. Treatment failure occurred in
276 (63.6%) treated teeth and 158 (36.4%) teeth maintained the result of the treatment
until the end of the study (censored teeth). The survival rate at 6 months was 36% for
laser treatment, and 36% for cyanoacrylate. There was no signifi cant difference between
the survival curves (p = 0.703). Gingival recession and abfraction increased the risk of
treatment failure by 2.04 (p = 0.002) and 2.76 (p < 0.001) times, respectively.
Conclusion: Overall, these two approaches to DH treatment had a survival rate of 36%
at 6 months. The most prevalent hypersensitive tooth is the fi rst premolar. Gingival recession and abfraction predict the recurrence of DH irrespective of patient age and sex.
