摘　　要：目的对中央尖患牙畸形患者应用窝沟封闭剂治疗的预后及治疗后感染情况进行分析,以降低感染率。方法将2010年1月-2012年12月医院151例(200颗)中央尖患牙畸形患者随机分为两组,分别给予窝沟封闭剂治疗为观察组及多次少量磨除法治疗为对照组,每组各100颗牙,观察两组患者预后及治疗后感染情况。结果观察组患者治疗总有效率为90.00%,明显优于对照组的68.00%;同时3年随访显示,观察组3年内龋齿发生率分别为6.00%、13.00%及22.00%,均明显低于对照组22.00%、41.00%及49.00%;此外3年内感染率观察组为21.00%,明显低于对照组的24.00%,两组比较,差异均有统计学意义(P<0.05)。结论中央尖患牙畸形患者应用窝沟封闭剂可有效改善患者的临床预后,降低患者感染率。OBJECTIVE To analyze the prognosis and infection situation of pit and fissure sealant in treating tooth abnormalities so as to reduce the infection rate .METHODS Totally 151 cases （200 teeth） with central fangs mal‐formation were selected from our hospital from Jan .2010 to Dec .2012 and randomly divided into two groups with 100 teeth respectively .The observation group was given pit and fissure sealant and the control group was treated with frequent and small amount of prophylactic odontotomy .The prognosis and infection status were observed and compared in the two groups .RESULTS The total effective rate in the observation group was 90 .00% in the obser‐vation group ,which was obviously superior to the control group with the rate of 68 .00% .And the follow‐up in the last three years showed that decayed tooth incidence rates in the observation group were 6 .00% ,13 .00%and22 .00% ,which were significantly lower than those of the control group with 22 .00% ,41 .00% and 49 .00% . Besides ,the infection rate in the 3 years of the observation group was 21 .00% ,which was significantly lower than that of the control group of 24 .00% （P〈0 .05） .CONCLUSION Pit and fissure sealant can effectively improve the prognosis and reduce infection rates of patients with abnormal central fangs .
