目的探讨口腔正畸治疗患者颞下颌关节骨关节病的患病情况。方法 296例接受正畸治疗的患者,对其临床资料进行回顾性分析,研究患者发生颞下颌关节骨关节病的发病因素。结果本组研究中,女性患者的颞下颌关节骨关节的发病率为3.05%(6/197),男性患者的颞下颌关节骨关节的发病率为1.01%(1/99),两组比较差异具有统计学意义(P<0.05);安氏Ⅱ类患者错牙合的检出率是安氏Ⅰ类错牙合检出率的4倍;安氏Ⅱ类患者错牙合的检出率是安氏Ⅲ类错牙合检出率的4倍,数据比较差异均具有统计学意义(P<0.05)。安氏Ⅰ类错牙合与安氏Ⅲ类错牙合的检出率比较差异无统计学意义(P>0.05)。结论临床颞下颌关节骨关节患者较为常见,患者的病症检出率与患者的年龄、性别以及错牙合等因素有密切关系。
Objective To investigate the prevalence of temporomandibular joint osteoarthrosis in orthodontic patients. Methods A total of 296 orthodontic patients were enrolled in this study. The clinical data of the patients were retrospectively analyzed to study the incidence of temporomandibular joint osteoarthrosis. Results The incidence of temporomandibular joint osteoarthrosis in female patients was 3.05% (6/197) in this study. The incidence of temporomandibular joint osteoarthrosis was 1.01% (1/99) in male patients. There was significant difference between the two groups (P <0.05). The detection rate of malocclusion in Class Ⅱ patients was 4 times that of Class Ⅰ malocclusion cases. The detection rate of malocclusion in Class Ⅱ patients was Class Ⅲ malocclusion detection rate of 4 times, the data were statistically significant differences (P <0.05). There was no significant difference in the detection rate between Class Ⅰ malocclusion and Class Ⅲ Malocclusion (P> 0.05). Conclusions The patients with TMJ joint osteoarthrosis are more common. The detection rate of the patients is closely related to the age, sex and the occlusion of the patients.
