About

This study aimed to evaluate the effectiveness of two treatments for dental hypersensitivity: cyanoacrylate (Super Bonder®) compared with use of low intensity laser treatment (LILT). As the cyanoacrylate is a lower cost treatment, the hypothesis in investigation is if this product is equally effective as the laser treatment.

Full description

The present study included 62 patients (15 male and 47 females, aged 12 to 60 years). The initial cervical dentin hypersensitivity was checked throughout a thermal test (air blast). The 434 teeth included were that with a score ≥5 in a numerical scale rating of pain. Teeth were randomly assigned according quadrants (split mouth design) - 216 were allocated to LILT group and 218 for the Super Bonder® group. Thermal tests with a tetrafluoroethane spray (Endo-Ice®) and air blast were performed and considered as baseline. Pain parameters were recorded using a numerical scale rating with 24 hours, 30, 90 and 180 days after the interventions. Quality of life of the patients was also assessed with the use of OHIP-14 at baseline and after 180 days.
