电动牙刷与手动牙刷对牙菌斑的控制效果

The Effect of Using Electric Toothbrush and Regular Toothbrush on the Removal of Dental Plaques

目的:比较电动和手动刷牙方式对牙面菌斑的清除效果。方法:将60名志愿者随机均分为手动组及电动组,2组志愿者均使用改良BASS刷牙法每天刷牙2次,手动组使用高露洁360全面口腔清洁牙刷3 min/次,电动组使用OMRON Pro Clinical B150智能声波电动牙刷2 min/次;分别于刷牙后第1、3及7周复诊,比较2组志愿者刷牙前后上、下颌颊和舌侧的牙平均牙菌斑指数,于刷牙后第1、7周时,组内比较不同牙面部位的牙菌斑清除率。结果:刷牙后,手动组上、下颌颊侧第1、3、7周和上颌舌侧第3、7周牙平均菌斑指数高于电动组,牙菌斑清除率低于电动组,差异有统计学意义(P<0.05);同组比较,手动组只有上颌舌侧牙齿第7周的牙菌斑清除率高于同组第1周,而电动组下颌颊侧以及上、下颌舌侧第7周牙菌斑清除率均高于同组第1周,差异有统计学意义(P<0.05)。结论:电动牙刷刷牙方法的牙菌斑清除率比普通牙刷高。

Objective:To compare the effect of using electric toothbrush and regular toothbrush on the removal of dental plaques.Methods:Sixty volunteers were randomly divided into regular group and electric group.They brushed their teeth twice a day using the modified BASS brushing method.The regular group used Colgate 360 comprehensive oral cleaning toothbrush for 3 min each time.The electric group used OMRON Pro Clinical B150 Smart Sonic Electric Toothbrush,2 min each time.They were revisited at 1,3 and 7 weeks after brushing.We compared the average plaque index of the teeth,maxillary cheek and tongue before and after brushing.At the 1st and 7th week after brushing,the plaque removal rate of different tooth surfaces was compared.Results:After brushing,the average plaque index of the maxillary and mandibular buccal sides at 1,3,and 7 weeks and the maxillary lingual side at 3 and 7 weeks were higher in regular group than those in electric group,but the plaque clearance rate was lower in regular group than that in electric group(P<0.05).Additionally,the plaque clearance rates of the maxillary lingual teeth were higher at week 7 than at week 1 in regular group(P<0.05),and the plaque clearance rates of buccal and mandibular lingual sides were higher at week 7 than at week 1 in electric group(P<0.05).Conclusion:The plaque removal rate of is higher using electric toothbrush than using regular toothbrush.
