We examined the percentage of patients undergoing other repair treatments after a procedure using the sealant and the duration between this procedure and other repair treatments to investigate prophylaxis of the first molar in patients in whom the oral cavity was controlled on periodic examinations at 3-month intervals. The first molars of patients were divided into those treated and untreated with the sealant. The clinical course was compared between the two groups to examine the effectiveness of the sealant. 1) The percentage of the first molars that underwent repair treatment with the sealant was 64.2%, while that of first molars that underwent repair treatment without this procedure was 85.1%. The percentage of first mandibular molars of girls undergoing repair treatment was 74.4%, which was the highest percentage among the groups examined. 2) The mean duration between eruption and repair treatment was 37.7 months for the first molars treated with the sealant and 16.6 months for the untreated first molars. In the first mandibular molars of girls, the mean duration between eruption and repair treatment was 35.4 months, representing the lowest value. These results suggest that the sealant inhibits dental caries development in juvenile permanent teeth with immature enamel.}, pages = {178--183}, title = {第1大臼歯のフィッシャーシーラントの予後について}, volume = {23}, year = {1997} }
