摘要
目的探讨应用窝沟封闭剂进行畸形中央尖患牙预防性治疗的可行性。方法将180颗畸形中央尖患牙按照抽签方法随机分为观察组(n=93)和对照组(n=87)。观察组采用窝沟封闭剂进行预防性治疗,对照组采用多次少量磨除的方法进行治疗。比较2组治疗疗效、中龋发生率、窝沟封闭剂保留与继发龋发病率及感染率。结果观察组治疗总有效率为94.62%(88/93),明显高于对照组的74.71%(65/87),差异有统计学意义(P<0.01);观察组与对照组3年中龋发生率分别为0.00%和29.89%(第1年),6.10%和30.77%(第2年),10.67%和40.00%(第3年),差异均有统计学意义(P<0.01);3年后继发龋病率观察组为5.33%(4/75);对照组感染发生率为19.54%(17/87),明显高于观察组的3.23%(3/93),差异有统计学意义(P<0.01)。结论应用窝沟封闭剂进行畸形中央尖患牙预防性治疗疗效显著,继发龋病率与感染率均较低,具有较好的可行性与实用性。
Objective To explore the feasibility of pit and fissure sealant in the preventive treatment of abnormal central tip teeth.Methods A total of 180 patients with abnormal central tip teeth were randomly divided into observation group （n =93） and control group （n =87） in accordance with the balloting.The observation group received preventive treatment with fissure sealants,and the control group received small grounding treatment with many times.The efficacy of treatment,in caries incidence,pit and fissure sealant retention and secondary caries incidence and infection rates were compared between the two groups.Results The total effectiveness rate of the observation group was 94.62％ （88/93）,which was significantly higher than that of the control group （74.71％,65/87）,and there was a significantly statistical difference between the two groups （P＜ 0.01）.The two groups were conducted a three-year review.The 3-year caries incidence rates of the observation group and the control group were as follows：1st year （0％ vs.29.89％）,2nd year （6.10 ％ vs.30.77 ％）,3rd year （10.67 ％ vs.40.00 ％）.The differences were statistically significant （P ＜ 0.01）.The secondary caries was 5.33 ％ （4/75） after 3 years.The infection rate was 19.54％ （17/87） in the control group,which was significantly higher than that in the observation group （3.2 3 ％,3/9 3）,and the difference had statistically significant difference （P ＜0.01）.Conclusion The preventive treatment of abnormal central tip teeth with fissure sealant is effective,and the rate of secondary caries and infection rates are lower.It has better feasibility and practicality.
