Abstract

INTRODUCTION

Some clinicians believed that mandibular deviation leads to facial asymmetry and it also had a correlation with temporomandibular disorders (TMDs). Posteroanterior (PA) cephalogram was widely reported as a regular record in treating facial asymmetry and craniofacial anomalies. The objective of this study was to analyze the relationship of menton deviation in PA cephalogram with temporomandibular disorders (TMDs) symptoms.

MATERIALS AND METHODS

TMJ function was initially screened based on TMD-DI questionnaire. PA cephalogram of volunteer subjects with TMDs ( = 37) and without TMDs ( = 33) with mean age of 21.61 ± 2.08 years was taken. The menton deviation was measured by the distance (mm) from menton point to midsagittal reference (MSR) horizontally, using software digitized measurement, and categorized as asymmetric if the value is greater than 3 mm. The prevalence and difference of menton deviation in both groups were evaluated by unpaired -test.

RESULT

The prevalence of symmetry group showed that 65.9% had no TMDs with mean of 1,815 ± 0,71 mm; in contrast, the prevalence of asymmetry group showed that 95.5% reported TMDs with mean of 3,159 ± 1,053 mm. There was a significant difference of menton deviation to TMDs ( = 0.000) in subjects with and without TMDs.

CONCLUSION

There was a significant relationship of menton deviation in PA cephalogram with TMDs based on TMD-DI index.

摘要

引言

一些临床医生认为下颌偏斜会导致面部不对称，并且它还与颞下颌关节紊乱病（TMDs）相关。后前位（PA）头影测量片作为治疗面部不对称和颅面畸形的常规记录被广泛报道。本研究的目的是分析PA头影测量片中颏点偏斜与颞下颌关节紊乱病（TMDs）症状之间的关系。

材料与方法

最初根据TMD-DI问卷对颞下颌关节功能进行筛查。对平均年龄为21.61±2.08岁的37例患有TMDs的志愿者和33例未患有TMDs的志愿者拍摄PA头影测量片。使用软件数字化测量，通过颏点到矢状面参考线（MSR）的水平距离（mm）来测量颏点偏斜，如果该值大于3mm则归类为不对称。通过非配对t检验评估两组中颏点偏斜的患病率和差异。

结果

对称组的患病率显示，65.9%的人没有TMDs，平均值为1.815±0.71mm；相比之下，不对称组的患病率显示，95.5%的人报告患有TMDs，平均值为3.159±1.053mm。患有和未患有TMDs的受试者中，颏点偏斜与TMDs之间存在显著差异（P = 0.000）。

结论

基于TMD-DI指数，PA头影测量片中的颏点偏斜与TMDs之间存在显著关系。
