目的评价氟化泡沫与氟保护漆治疗龈下刮治及根面平整术后敏感的效果。方法选取2009年9月至2011年3月北京大学口腔医院门诊部牙周科行龈下刮治及根面平整术后1周有1颗以上的切牙中等程度敏感的患者209例(患牙503颗),根据患者的年龄、性别、牙齿数目分层,随机分为对照组(采用生理盐水涂擦根面)、氟保护漆组(采用氟保护漆脱敏治疗)、氟化泡沫组(采用氟化泡沫脱敏治疗)。用视觉模拟评分(VAS)法对牙齿敏感程度进行评估,分别于脱敏前以及脱敏后即刻、1周、1个月记录VAS值,并记录各组临床操作时间。结果脱敏前各组VAS值相近,差异无统计学意义(P>0.05);脱敏后各时间点对照组与其余两组差异有统计学意义(P<0.05);氟保护漆组在脱敏后1周和1个月时VAS值均低于氟化泡沫组,但差异无统计学意义(P>0.05)。氟保护漆组每颗牙的平均临床操作时间与其余两组差异有统计学意义(P<0.05)。结论氟化泡沫和氟保护漆均可减轻龈下刮治和根面平整术后敏感的程度,氟化泡沫操作更简单,更适合临床推广使用。
Objective To evaluate the sensitive effect of fluorinated foam and fluorinated protective lacquer after subgingival scaling and root planing. Methods From September 2009 to March 2011, Peking University Stomatological Hospital, Department of Stomatology, Peking University Hospital, subgingival curettage and root planing after a week there are more than 1 incision in a moderate degree of sensitivity in 209 patients (with teeth 503). According to the patient’s age, sex and number of teeth, they were randomly divided into control group (treated with normal saline to rub the root surface), fluoroprotective paint group (fluorinated paint desensitization treatment), fluorinated foam group Fluoride foam desensitization treatment). The visual analog scale (VAS) method was used to evaluate the sensitivity of the teeth. VAS values were recorded before desensitization and immediately after desensitization. The VAS values were recorded and the clinical operation time was recorded. Results Before desensitization, there was no significant difference in VAS between groups (P> 0.05). There was significant difference between the control group and the other two groups after desensitization (P <0.05) VAS values at 1 week and 1 month after sensitization were lower than those in fluorinated foam group, but the difference was not statistically significant (P> 0.05). The average clinical operation time of each tooth in fluoride protective paint group was statistically different from the other two groups (P <0.05). Conclusion Both fluorinated foam and fluorinated protective coatings can reduce the sensitivity of subgingival scaling and root planing. Fluorinated foam is easier to operate and more suitable for clinical use.
