Abstract Objective To evaluate the efficacy of three kinds of desensitizer for the prevention of dentin hyper-sensitivity in deep cavities.Methods The 195 teeth of 114 cases with deep caries were divided into three groups randomly,and before curable resin filling treated with three different desensitizers as Oravive desensitizer,Gluma desensitizer and calcium hydroxide respectively. Effective rates of the three agents on teeth were examined immediately,one month and three months after the treatment.Effective rates were compared in three groups.Results The efficacy of the Oravive and Gluma groups were obviously higher than that in calcium hydroxide group (P＜0.01).There was no significant difference between Oravive and Gluma groups (P＞0.05).After three months of the treatment,Oravive group has significantly higher than Gluma and calcium hydroxide groups (P＜0.01).But the efficacy of Gluma was similar at that of calcium hydroxide group.Conclusions Oravive desensitizer is an effective desensitizer preventing dentin hypersensitivity of post-filling complications in deep caries.
