The purpose of this study was to investigate the effects of cleaning and polishing methods on primary enamel surfaces. Fifty-nine extracted or exfoliated caries free primary anterior human teeth were used. The cleaning and polishing methods used in this study were as follows: application of 10% NaOCl, polishing with a brush cone or a polishing brush at a low speed (600-6000 r.p.m.), polishing with a brush cone and various polishing pastes, cleaning with an air polisher Prophy-Jet or Quick-Jet with NaHCO3 powder and water. The following observations were obtained using the SEM: (1) Air polishing systems were useful for cleaning the enamel surface, (2) It was likely that materials such as organic films will remain on the enamel surface polished with a brush cone or polishing brush alone, and (3) The effect of 10% NaOCl application for 30 seconds was the lowest.
本研究的目的是调查清洁和抛光方法对乳牙釉质表面的影响。使用了59颗拔除或脱落的无龋乳牙前牙。本研究中使用的清洁和抛光方法如下：应用10%次氯酸钠、用刷形锥或低速（600 - 6000转/分钟）抛光刷进行抛光、用刷形锥和各种抛光膏进行抛光、用配备碳酸氢钠粉末和水的空气抛光器Prophy - Jet或Quick - Jet进行清洁。使用扫描电子显微镜获得了以下观察结果：（1）空气抛光系统有助于清洁釉质表面，（2）单独用刷形锥或抛光刷抛光的釉质表面可能会残留有机膜等物质，（3）应用10%次氯酸钠30秒的效果最差。
