第1大臼歯のフィッシャーシーラントの予後について Prognosis after Use of the Pit and Fissure Sealant 寺本, 幸代 吉武, 陽子 林, 于昉 宮沢, 裕夫 フィッシャーシーラント 第1大臼歯 修復処置 application/pdf Since Buonocore initially introduced the use of pit and fissure sealant to clinical dental practice, sealant has been used as an effective prophylactic system due to advances in high molecular weight materials. 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. 松本歯科大学学会 1997-12-31 jpn journal article VoR https://mdu.repo.nii.ac.jp/records/761 AN00232590 0385-1613 松本歯学 23 3 178 183 https://mdu.repo.nii.ac.jp/record/761/files/matsumoto_shigaku_23-03-05.pdf application/pdf 380.4 kB 2012-05-24
