在校学生颞下颌关节紊乱病与心理因素关系的研究

目的:探讨心理因素对在校生颞下颌关节紊乱病(TMD)的影响.方法:对52例14～ 26岁确诊为颞下颌关节紊乱病(TMD)及53名健康在校生进行颞下颌关节紊乱病专科检查,并填写症状自评量表(SCL-90).患者组分为咀嚼肌功能紊乱(MD)组26例、关节盘移位(TD)组14例、关节盘移位咀嚼肌功能紊乱并存(MD+TD)组12例,按病程分为急性组32例(病史≤6个月),慢性组20例(病史＞6个月).用SPSS 17.0对各分组SCL-90总分及因子分进行比较分析.结果:TMD组SCL-90总分及各因子得分高于健康对照组(P＜0.05).MD组得分与TD组得分差异无统计学意义(P＞0.05),MD+ TD组的SCL-90总分及除抑郁、恐怖和精神病性外的其他因子得分显著高于前2组(P＜0.05).急性组躯体化得分高于慢性组(P＜0.05),其他项目2组差异无统计学意义(P＞0.05).TMD患者SCL-90总分与疼痛等级呈正相关关系.结论:心理因素对患TMD的在校生影响显著,可影响TMD相关疼痛的程度,对在校生的TMD进行治疗时应考虑心理的相关治疗.

A study on the relationship between temporomandibular disorders and psychological factors in students

Objective:To explore the influence of psychological factors on temporomandibular disorders(TMD) in school students.Methods:52 school students aged 14-26 years with TMD classified as muscular dysfunction (MD,n =26),temporomandibular displacement(TD,n =14) and MD with TD(MD +TD,n =12),and 53 healthy adolescents as the controls were investigated.All the participants accepted TMD examination and their psychological status were tested by symptom checklist-90 (SCL-90).The patients were divided into acute(case history ≤6 months,n =32) and chronic(case history ＞6 months,n =20) groups.The psychological differences among the related groups were analyzed by SPSS 17.0 statistical software package.Results:The total and the factor scores of the TMD group were higher than those of control(P ＜ 0.05).There was no significant statistically difference between the MD group and the TD group(P ＞ 0.05).MD + TD group got higher SCL-90 total score and factor scores (except depression,phobic anxiety and Psychoticism score) than the other 2 groups (P ＜ 0.05).The acute and chronic group got similar SCL-90 total scores and factor scores (P ＞ 0.05),except somatization score (P ＜ 0.05).There was a positive correlation between the TMD pain level and total score of SCL-90.Conclusion:The psychological status have remarkable influence on the students with TMD.The pain degree of TMD is affected by psychological factors.Therefore,psychological therapy should be applied during the diagnosis and treatment of students with TMD.
