自制磨光糊剂在临床及离体牙应用的效果

Effects of using potishing paste after ultrosonic scaling in vitro and in vivo

牙周洁治后选用合适的磨光糊剂磨光牙面既可去除残余色素,又可提高牙面的光洁度,从而延缓菌斑、牙石和色素的重新沉着,巩固疗效.我们对自行配制的一种磨光糊剂(粗细二型)作离体牙实验和临床疗效观察:1.24颗离体牙洁治后经自制磨光糊剂磨光用光波干涉显微镜(light wave interferencemicroscope)观察牙面,其光洁度大大提高,可达到进口糊剂同等磨光效果.2.临床以12例龈炎患者的72颗上前牙为实验对象,洁治后一侧以自制糊剂磨光,另一侧不磨光,纵向观察8～10周,磨光侧牙面的色素沉积明显少于不磨光侧.

This study evaluated the in vitro and in vivo polishing effects of a prophy paste after ultrasonic scaling.1. 24 freshly extracted molars were polished with the tested paste after scaling. The roughness of tooth surfaces was measured by light wave interference microscope before and after polishing. An imported prophylaxis paste NUPRO was used as control. The results showed that the polished tooth surfaces were significantly less rough than those without polishing. The tested prophy paste showed similar effectiveness to that with NUPRO prophylaxis paste.2. The lingual surfaces of 72 maxillary incisors from 12 gingivitis patients were divided into two groups by split-mouth method. Group A was scaled and polished while group B was only scaled. At 0,2,4 ,6,8,10 weeks, Stain Index, Gingival Index, Bleeding Index and Plaque Index were examined and recorded. The results indicated that within 8-10 weeks Stain Index was significantly lower in the polished group compared to the unpolished group. No signifcant difference was found in GI, BI and PLI.According to these results, The prophy paste could be recommended for clinical use after scaling.
