年轻恒牙畸形中央尖患者的预防性治疗

Analysis of Abnormal Central Cusp Preventive Treatment method and effect of tip of Young Permanent Teeth

目的分析年轻恒牙畸形中央尖患者的预防性治疗方法及效果。方法随机抽取2013年1月至2016年1月中小学生经过体检发现的畸形中央尖患者24例,随机均分成A组(选取单纯树脂覆盖法)和B组(选取改良多次调磨法),观察两组术中患牙的敏感情况、术后的牙根情况。结果两组共有6颗患牙出现充填材料脱落的情况,分别为A组2颗,B组4颗;A组的治疗有效率为93.3%,B组的治疗有效率为86.7%,差异无统计学意义(P>0.05)。两组在治疗的过程中,A组术中的患牙敏感率为6.7%,B组术中的患牙敏感率为36.7%,A组的患牙敏感率明显低于B组,差异有统计学意义(P<0.05)。结论单纯树脂覆盖法对年轻恒牙畸形中央尖患者的治疗效果优于改良多次调磨法,可以有效地降低年轻恒牙畸形中央尖折断或者牙髓病变的发生率,且对患牙的刺激性小。

Objective To analyze the preventive treatment and effect of the young permanent teeth with abnormal central cusp. Methods Randomly selected from January 2013 to January 2016 in middle and primary school students after physical examination found that 24 cases of abnormal central cusp patients were randomly divided into A group （selected pure resin covered method） and B group （selected modified multiple grinding meth-od） ,observe the two treatment methods intraoperative sensitive situation, postoperative condition of the root. Results The effective rates of group A and group B were 93.3% and 86.7% , compared the two groups had no significant difference （P 〉0. 05） . the tooth sensitivity rate of patients in the A group was 6.7% , significantly lower than group B patients teeth sensitivity rate of 36. 7% , P 〈 0 .05, he difference was statistically significant. Conclu-sion The pure resin covering method of young permanent teeth of central cusp deformity treatment is better than the modified multiple grinding meth-od, can effectively reduce the young permanent teeth broken abnormal central cusp or pulp disease incidence, and is less irritant to teeth.
