Signs and symptoms of temporomandibular disorders and their impact on psychosocial status in non‐patient university student's population

Background and Purpose. Temporomandibular disorders (TMD) exhibit a combination of signs and symptoms, mainly characterized by pain and dysfunction, which impairs the functional capacity of the mastication system. These symptoms may produce a negative impact on social activities, employment and leisure. The aim of this study was to early identify the signs and symptoms of TMD and their impact on daily life of non‐patient university students. Methods. Data were collected from 183 students of the dentistry course. The Axis II of the Research Diagnostic Criteria for Temporomandibular Disorders was administered and analyzed using Spearman test at a significance level of 0.05. Results. Among the 183 participants, 107 were women (58.47%) and 76 were men (41.53%). Age ranged from 18 to 47, with a mean age of 25.35 years. In relation to pain intensity and disability, 129 participants (70.88%) reported no pain in the previous 6 months. An analysis of depression revealed that 35 (19.67%) had moderate and 7 (3.83%) had severe depression. The assessment of nonspecific physical symptoms including pain revealed that nine (4.92%) exhibited moderate symptoms, and one (0.55%) exhibited severe symptoms. The nonspecific physical symptoms excluding items of pain analysis revealed that 44 (24.04%) exhibited moderate symptoms, and 91 (49.73%) exhibited severe. The functions reported as most adversely affected by jaw disability were yawning, eating hard foods, chewing, smiling and laughing. Regarding the habit, 64 (35%) confirmed having the nighttime and 59 daytime (32.3%) teeth grinding with a significant correlation with the four domains analyzed. A significant correlation was observed among all domains. Conclusion. This study analyzed a young population that exhibited para‐functional habits and nonspecific physical symptoms excluding pain that need some intervention since they could progress to a symptomatic TMD in future.

A型肉毒毒素对TMD引起的面肌疼痛治疗效果的临床探讨

目的：对A型肉毒毒素在治疗TMD引起的面肌疼痛患者的治疗效果进行临床观察,为A型肉毒毒素在TMD引起的面肌疼痛治疗中的应用提供参考依据。方法方便选取2014年4月-2016年4月于该院就诊的105名因TMD引起面肌疼痛于该科就诊的患者随机分为2组,治疗组和对照组,治疗组52名患者,对照组53名患者。治疗组应用A型肉毒毒素对有明显压痛的面肌进行肌肉内注射;对照组应用0.9%氯化钠注射液进行肌内注射进行对照。分别于治疗后第1周末、第1月末和第3月末对治疗效果进行统计学比较。结果治疗后第1周末、第1月末和第3月末治疗组的有效率分别为78.08%、88.46%和96.15%;对照组的有效率分别为13.21%、9.43%和3.77%。治疗后第1周末、第1月末和第3月末治疗组和对照组治疗有效率差异均有统计学意义,P<0.05。结论局部注射A型肉毒毒素对TMD引起的面肌疼痛有良好的治疗效果,并且效果持久。
