OBJECTIVE:Dentin hypersensitivity, or what patients may describe as "sensitive teeth," is defined as a short, sharp pain arising from exposed dentin in response to thermal, evaporative, tactile, electrical, osmotic or chemical stimuli. It is widely accepted that dentin hypersensitivity is an uncomfortable condition that also affects function and quality of life. This study determines the differences in efficiency of three desensitizing products when compared with a placebo. METHODS: A randomized controlled clinical trial was conducted to compare three different professional dentin desensitizer agents in 52 patients. The age and sex of the patients was recorded. Gluma Desensitizer (Heraeus Kulzer), UltraEZ (Ultradent Products, Inc) and Duraphat (Colgate Oral Pharmaceuticals, Inc, New York, NY, USA) were used as desensitizer agents and distilled water was used as the placebo. The baseline measurement of the dentin hypersensitivity was made by using a visual analog scale (VAS). Twenty-four hours and seven days after application of the desensitizer agents and placebo, a new VAS analysis was conducted for patients' sensitivity level. The desensitizer agents were compared in terms of mean values, and ANOVA was used for testing differences among the groups (p<0.05). RESULTS: The results showed that the mean pain scores of the placebo group were significantly higher than that of the study groups (p<0.05). The VAS analysis revealed a significant decrease in dentin hypersensitivity over time with the use of agents (p<0.05). No statistically significant difference was found among the three desensitizing agents (p>0.05). CONCLUSIONS: These three desensitizing agents, which contain different active ingredients, were effective in relieving dentin hypersensitivity. However, no superiority was found in dentin sensitivity relief among the agents.
