Abstract PURPOSE: To evaluate the effectiveness of a dentin bonding agent containing HEMA compared to a resin emulsion in the reduction of cervical dentin hypersensitivity (CDH). MATERIALS AND METHODS: The study was a randomized-within-subject, double blind design. Twenty patients who were suffering from CDH from at least two teeth (canines and/or premolars) were enrolled. The subjective perceptions of pain in response to tactile, air blasts and cold ethyl chloride stimuli were evaluated using a visual analog scale (VAS) at baseline and 10 minutes, 1 week and 4 weeks after the treatments. Scotchbond 1 (a dentin bonding agent similar to Single Bond in the USA) and MS Coat (a resin emulsion), both applied according to the manufacturers' directions, were selected for the study. RESULTS: Multiple regression ANOVA for repeated measures showed that both treatments significantly reduced the CDS with respect the baseline values after just 10 minutes. There were no significant differences between the ability of the two treatments to reduce CDH for each of the three evaluation stimuli or for subjective evaluation.
