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

Condition Intervention Phase
Dentin Hypersensitivity
Dentin Sensitivity
Other: Cyanoacrylate
Radiation: Laser

Estimated Enrollment: 17
Study Start Date: August 2008
Study Completion Date: February 2009
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Cyanoacrylate
3 applications of cyanoacrylate (48 hours interval)at the cervical region of the sensitive tooth
Other: Cyanoacrylate
3 applications of cyanoacrylate (48 hours interval)at the cervical region of the sensitive tooth
Other Name: Superbonder
Active Comparator: Laser
3 Low intensity laser application (48 hour interval). The application of 1J/cm2 was performed for eight seconds at three points along the dental neck, using the infrared wavelength (660nm)
Radiation: Laser
This process was conducted three times with an interval of 48 hours between applications, according to laser's manufacturer advice Clean Line Easy Laser - LILT®, Clean Line Easy Laser Doctor Dental Products Industry LTDA, BRA). For dentin hypersensitivity, the application of 1J/cm2 is recommended for eight seconds at three points along the dental neck, using the infrared wavelength (660nm).
