Abstract

AIM

The purpose was to evaluate the morphological variations of the condyle in patients presenting with myalgia associated with and without clicking of temporomandibular joint (TMJ) and its possible effect on the contour and height.

SETTING AND DESIGN

Cross sectional study.

MATERIAL AND METHODS

A total of 60 patients comprising of 20 patients with myalgia, 20 patients with myalgia associated with clicking of TMJ, and a control group of 20 patients without any signs and symptoms of temporomandibular disorder were selected for purpose of the study. Using a digital panoramic radiograph, the contour of the condyle was evaluated for shape, condylar height (CH), and condylar asymmetry.

STATISTICAL ANALYSES USED

Chi-square test, One- way ANOVA.

RESULTS

Rounded contour of the condyle was the most prevalent shape of the condyle amongst the three groups. There was a significant decrease in mean right and left CH in subjects with myalgia (0.71 cm and 0.73 cm) and subjects with myalgia associated with clicking (0.65 cm and 0.62 cm) compared to control group subjects. There was also an increase in the mean asymmetry index in subjects with myalgia presenting with clicking (2.362 ± 1.4) and without clicking (1.388 ± 2.1) (P < 0.05).

CONCLUSION

Within the limitations of the current study, round contour of the condyle is the most common variant. Subjects with myalgia showed a significant reduction in condyle height. Condyle contour, height, and asymmetry may not predispose the joint for clicking.

摘要

目的

评估患有与不伴有 TMJ 弹响的肌痛患者的髁突形态变化及其对轮廓和高度的可能影响。

设置和设计

横断面研究。

材料和方法

共选择 60 例患者，其中 20 例为肌痛患者，20 例为伴有 TMJ 弹响的肌痛患者，20 例为无任何 TMJ 紊乱症状和体征的对照组患者。使用数字全景片评估髁突的轮廓形状、髁突高度（CH）和髁突不对称性。

统计分析方法

卡方检验、单因素方差分析。

结果

三组中最常见的髁突形状为圆形。与对照组相比，肌痛患者（右侧和左侧 CH 分别为 0.71cm 和 0.73cm）和伴有弹响的肌痛患者（右侧和左侧 CH 分别为 0.65cm 和 0.62cm）的 CH 均值明显降低。伴有弹响的肌痛患者（2.362±1.4）和无弹响的肌痛患者（1.388±2.1）的 CH 不对称指数也有所增加（P<0.05）。

结论

在本研究的限制范围内，圆型髁突是最常见的变异类型。肌痛患者的髁突高度明显降低。髁突轮廓、高度和不对称性可能不会使关节易于弹响。
