초록
최근 air-abrasion기술이 새로운 법랑질 표면처리법으로 소개되고 있는데, 이것이 산부식 처리한 것보다 치면열구전색 전처리에 있어 더 나은 결과를 보이는지 연구할 목적으로, 저자들은 표면처리법 및 재료에 따른 미세누출도의 차이를 비교해 보고자 하였다. 9개의 군으로 나눈 시편치아에 산부식(1, 4, 7군), air-abrasion(2, 5, 8군), air-abrasion 후 산부식 (3, 6, 9군) 처리한 후 3종의 치면열구전색재(
Recently. the reintroduction of air-abrasion technology in dentistry has added a new potential method of pretreating teeth prior to placing sealants. The purpose of this in vitro study was to investigate microleakages of several pit and fissure sealants following various surface pre-treatment methods to the enamel, because there was a question concerning the validity of claim that this method was better than the conventional acid etching. Permanent molars were divided randomly into nine groups and treated accordingly: acid etching(group 1, 4, 7), air-abrasion(group 2, 5, 8), acid etching after air-abrasion(group 3, 6, 9). Then the authors placed and cured the three kinds of sealants(group
