摘要
目的:本研究拟通过音法检测正畸治疗前后患者的咬合稳定性,并通过对比主、客观两种检测方法,评价用主观法检查稳定性的可靠性。方法:选择2003年至2005年间在北京大学口腔医学院正畸科就诊的错畸形患者64例为初诊组;全口固定正畸矫治结束即刻患者15例为矫治结束即刻组。用主观听诊法及客观录音分析法评估患者音。对客观检查结果,通过卡方检验比较初诊组与矫治结束即刻组间咬合稳定性的差别,比较不同错类型的初诊患者间咬合稳定性的差别。以客观法为金标准计算主观法诊断的准确度,通过Kappa检验分析主客观方法间的一致性。结果:(1)43.75%(28/64)的初诊患者咬合不稳定,卡方检验显示不同类型的错畸形间咬合稳定性的差异没有统计学意义。(2)15例固定矫治结束即刻患者中40%(6/15)的患者咬合不稳定。(3)卡方检验发现初诊患者组与矫治结束即刻组咬合稳定性的差异没有统计学意义。(4)主观法音检查的准确度为81.01%(64/79)。(5)Kappa检验表明主客观两种方法存在较高一致性,Kappa值为0.488。结论:(1)正畸治疗前后均有部分患者咬合不稳定,不同类型错患者间咬合稳定性率差异没有统计学意义。(2)主、客观两种方法存在较高一致性。
Objective： To analysis the stability of the occlusion before and after the orthodontic treatment by gnathosonics; To evaluate the reliability of the stethoscope method by comparing the subjective （stethoscopy） and objective （ digital occlusal sound recording） methods of checking the occlusal sound. Methods： Sixty-four new patients with malocclusion were selected as the before treatment group, these patients were not subject to any previous orthodontic treatment, facial surgery or injury; the treatment complete group included 15 patients who were just debonded the fixed appliance. Both stethoscope and digital occlusal sound recording were used to evaluate the occlusal sound. The occlusal stability before and after orthodontic treatment was compared depending on the results from the objective examination. The stability of the occlusion between different types of malocclusion before treatment was compared also. The veracity and reliability of the stethoscope method were analysis using the objective method as the golden standard. Results： （ 1 ） 43.75% （28/64） of the 64 new patients showed unstable occlusal sound. ANOVA test showed that there were no statistically significant differences between the unstable rates in different type of malocclusion. （2） 40% （6/15） of the 15 treatment complete patients had unstable occlusions. （3） There were no statistically significant differences between the unstable rate pre- and posttreatment. （4） The veracity of the stethoscopes was 81.01% （64/79）. （5） Kappa test showed that the stethoscopes and the digital recording method were consistent; the Kappa value was 0.488, P 〈0. 001. Conclusion： （1） There was no statistically significant difference of the unstable occlusion rate between the two groups, and between the different types of malocclusion before treatment. （2） Using stethoscopes method to check the occlusal sound is reliable. The veracity could be improved significantly with increased experiences.
