牙龈炎和牙周炎总的发病率高达81％以上,菌斑和牙石与之密切相关,临床表现主要为炎症。洁治术可去除牙石和菌斑,因而可有效地控制炎症。传统的手持器械洁治方法(传统法)与超声器械洁治方法(超声法)相比,费时费力。但后者的临床效果和对牙面损伤情况,尚需研究,省时程度也需作定量分析。本研究以传统法为对照,根据菌斑指数和牙龈指数的变化、洁治时间以及术后牙面划痕的扫描电镜观察结果,拟对超声法龈上洁治术的效果,从临床角度作出综合评价。
The total incidence of gingivitis and periodontitis is as high as 81%. Plaque and calculus are closely related to the main clinical manifestations of inflammation. Decontamination removes calculus and plaque, thus effectively controlling inflammation. The traditional method of hand-held instruments (traditional method) is more time consuming and labor intensive than the ultrasonic method (ultrasonic method). However, the latter's clinical effect and the damage to the tooth surface need to be studied. The time-saving degree also needs to be quantitatively analyzed. In this study, the traditional method was used as control. According to the changes of plaque index and gingival index, the time of cleaning treatment and the scanning electron microscope observation of postoperative tooth surface scratches, the effect of superset method on supraginggorization was proposed from clinical point of view Overview.
