This study was designed to investigate the effects of a 10% strontium chloride dentifrice on patients with dentin hypersensitivity following periodontal surgery. The data was obtained from a double blind clinical study which was specifically conducted to determine the desensitizing effect of a dentifrice containing 10% strontium chloride as compared to a placebo. The results obtained were as follows. 1. The total pain score at first week after periodontal surgery increased about twice as much as that before surgery. Pain scores declined steadily in the group having strontium chloride therapy. At the seventh week after treatment (eighth week post-operatively) the pain score was reduced to be 0.64±0.12, which was much lower than the pre-operative level (1.20±0.14). The placebo group also showed an increase in pain scores at the first week after periodontal surgery, but hypersensitivity was not reduced until the fourth week post-operatively. And the pain scores at the eighth week after periodontal surgery were still above pre-operative levels. 2. The rate of a reduction of pain scores in experimental group was 26.8% in the first week. It was a significant reduction to pre-treatment level. At the seventh week after treatment (eighth week postoperatively) the pain score showed a 75.5% reduction. The placebo group showed only 34.2% reduction at the seventh week after treatment. 3. A 10% strontium chloride dentifrice was significantly more effective than a placebo dentifrice in relieving the incidence and severity of dentin hypersensitivity in patients who had undergone periodontal surgery.
