Pain and temporomandibular disorders in patients with eating disorders

Abstract Orofacial pain and temporomandibular dysfunction may cause chronic facial pain, which may interfere with the emotional state and food intake of patients with eating disorders (ED), such as anorexia nervosa (AN) and bulimia nervosa (BN). Sixty-four patients were assigned to four groups: Group A (AN – restricting subtype): 07; Group B (AN – purging subtype ): 19; Group C (BN): 16; and Group D (control): 22. Complaints of pain are more prevalent in individuals with eating disorders (p<0.004). There are differences between the presence of myofascial pain and the number of hospitalizations (p = 0.046) and the presence of sore throat (p=0.05). There was a higher prevalence of masticatory myofascial pain and complaints of pain in other parts of the body in ED patients; however, there was no difference between ED subgroups. There was no difference in the number of self-induced vomiting between ED patients with and without myofascial pain.

摘要：口面部疼痛（Orofacial pain）与颞下颌关节功能障碍（Temporomandibular Dysfunction）可引发慢性面部疼痛，此类疼痛可能干扰进食障碍（Eating Disorders, ED）患者的情绪状态与进食行为，例如神经性厌食症（Anorexia Nervosa, AN）与神经性贪食症（Bulimia Nervosa, BN）患者。本研究共纳入64例患者，分为四组：A组（AN限制性亚型）7例；B组（AN清除亚型）19例；C组（BN组）16例；D组（对照组）22例。进食障碍患者的疼痛主诉患病率更高（p<0.004）。肌筋膜疼痛（Myofascial Pain）的发生情况与住院次数（p=0.046）、咽痛症状的存在（p=0.05）存在统计学差异。进食障碍患者的咀嚼肌筋膜疼痛（Masticatory Myofascial Pain）及全身其他部位疼痛主诉的患病率更高，但进食障碍各亚组之间无显著差异。伴与不伴肌筋膜疼痛的进食障碍患者的自我诱吐（Self-induced Vomiting）次数无显著差异。
