研究目的:

探索评估患者菌斑控制效果的方法,比较主动法和被动法(每天晚上睡前刷牙至少3分钟运用所学到的正确刷牙方法科学有效刷牙,直至刷牙干净,同时录制刷牙视频发送给项目组成员以接受个性化指导,例如指出正确的刷牙方法、纠正错误的刷牙方法和刷牙时长等,通过医务人员根据视频对受试者进行被动评估和改进,即被动法。需要受试者2-3天/周在睡前刷牙前先用清水漱口,用菌斑指示剂将牙齿染色(用小棉球蘸取菌斑指示剂药液,涂于每个指数牙的牙面上,再次漱口后,牙面被染色的区域,即是附着的菌斑),并用学习到的方法科学有效刷牙,直至将牙面上所有指示剂清除干净,使受试者可以对菌斑控制实现自我评价和主动改进,即主动法。)干预措施对自我菌斑控制的效果,为改善患者自我菌斑控制效果提供依据方法。  

Objectives of Study:

To explore methods for evaluating the effectiveness of patients' plaque control, and to compare the active method and the passive method (brushing teeth for at least 3 minutes every night before going to bed, using the correct brushing method learned scientifically and effectively to brush teeth until they are clean. At the same time, record the brushing video and send it to the project team members for personalized guidance, such as pointing out the correct brushing method, correcting incorrect brushing methods, and the duration of brushing, etc. Through medical staff's passive assessment and improvement based on the video, the passive method is adopted. The subjects need to rinse their mouths with water 2-3 times a week before brushing teeth, stain the teeth with a plaque indicator (using a small cotton ball to dip the plaque indicator solution and apply it to the surface of each index tooth, rinse the mouth again, and the stained area on the tooth surface is the attached plaque), and brush teeth scientifically and effectively using the learned method until all the indicators on the tooth surface are removed, so that the subjects can self-evaluate and actively improve their plaque control, which is the active method). To evaluate the effect of the intervention measures on self-plaque control, and provide a basis for improving the self-plaque control effect of patients.

随机方法(请说明由何人用什么方法产生随机序列):

由王兆伟采用分层随机分组方法,根据性别(男/女)、牙周组织炎症性疾病的严重程度(牙龈炎/牙周炎)为分层因素,所以可以分为女性牙龈炎、女性牙周炎、男性牙龈炎、男性牙周炎四类受试者,每类受试者编号为奇数分入A组(先被动法干预刷牙再主动法干预刷牙),偶数分入B组(先主动法干预刷牙再被动法干预刷牙)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Wang Zhaowei used the stratified random grouping method. Based on the factors of gender (male/female) and the severity of periodontal tissue inflammatory diseases (gingivitis/dental periodontitis), the subjects could be divided into four groups: female gingivitis, female periodontitis, male gingivitis, and male periodontitis. Each group was numbered with odd numbers and assigned to group A (first passive method intervention for brushing teeth followed by active method intervention for brushing teeth), and even numbers were assigned to group B (first active method intervention for brushing teeth followed by passive method intervention for brushing teeth).
