干扰对特发性牙颈部病损临床疗效影响的研究

The effect of occlusal interference on the restoration of the idiopathic cervical lesions

目的:研究干扰对特发性牙颈部病损临床治疗效果的影响。方法:第一部分:纳入该院口腔科特发性牙颈部病损就诊患者83例,患牙295颗;临床检查存在干扰142颗作为治疗1组,无干扰153颗作为治疗2组,分别行纳米树脂治疗。随访2年。评价疗效,卡方检验。第二部分:治疗1组失败患牙60颗,随机分为实验组和对照组,各30颗。实验组纳米树脂充填治疗特发性牙颈部病损后精确去除咬合干扰因素,对照组仅纳米树脂充填治疗。治疗2组失败患牙29颗,随机分为实验组14颗和对照组15颗。实验组降低咬合,对照组仅纳米树脂充填治疗。随访1年,评价效疗,卡方检验。结果:第一部分:治疗1组和2组牙颈部病损治疗成功率分别为57.75%和81.05%(P<0.05)。第二部分:治疗1组失败患牙60颗,实验组和对照组成功率分别为83.33%和56.67%(P<0.05)。治疗2组失败患牙29颗,实验组和对照组成功率分别为85.72%和40%(P<0.05)。结论:充填治疗时配合精确去除咬合干扰因素治疗,可提高特发性牙颈部病损的临床疗效。

Objective： To evaluate the effect of occlusal adjustment on the restoration of the idiopathic cervical lesions. Methods： 295 teeth with dental idiopathic cervical lesions in 83 patients were divided into 2 groups, 142 teeth with occlusal interference were in- cluded in group 1 and the 153 without occlusal interference in group 2. The deffects of all the teeth were filled with Z350 nano-resin and followed up for 2 years. Then the teeth with treatment failure were divided into the experimental group（ A, 30 from group 1 and 14 from group 2） and the control group （B, 30 from group 1 and 15 from group 2）. The idiopathic cervical lesions of all teeth were filled with Z350 nano-resin, the occlusion of the corresponding teeth in group A was adjusted at the same time, that of group B was not trea- ted. The cases were followed up for 1 year. Results： The success rate of group 1 and group 2 was 57.75% and 81.05% repectively （P 〈 0.05）. A subsequently treatment and 1 year follow-up showed that the success rate of gorup A and B for the cases with treatment failure of group 1 was 83.33% and 56.67% （ P 〈 0.05）, for group 2 was 85.72% and 40% （P 〈 0.05 ） respectively. Conclusion ： The occlusal adjustment is benefit to the clinical effect of the treatment outcome of idiopathic cervical lesions.
