Abstract

Objective: Temporomandibular disorders (TMDs) often impair mastication and quality of life. While oral behaviors are recognized as risk factors, the role of appetitive traits remains unclear. This study investigated associations among oral behaviors, appetitive traits, and TMDs.

Methods: A matched case-control design included 84 patients with TMDs and 84 age‑ and sex‑matched controls. Participants completed validated Chinese versions of the Oral Behavior Checklist (OBC) and the Adult Eating Behavior Questionnaire.

Results: TMD patients demonstrated significantly higher waking‑state oral behaviors and overall OBC scores. Regression analysis revealed that high OBC grades were associated with TMDs. Specific behaviors-muscle tensing without tooth contact, sleeping with jaw pressure, and unilateral chewing-were significantly linked. Appetitive traits showed no significant association.

Conclusion: Oral behaviors, particularly waking‑state muscle tension without tooth contact, were strongly associated with TMDs, whereas appetitive traits were not. Behavioral assessment and modification may aid TMD management.

口腔行为、食欲特征和颞下颌紊乱之间的关系——一项匹配的病例对照研究。

目的：颞下颌障碍（TMDs）常影响咀嚼和生活质量。虽然口腔行为被认为是危险因素，但食欲特征的作用尚不清楚。本研究探讨了口腔行为、食欲特征和tmd之间的关系。方法：匹配的病例-对照设计包括84例tmd患者和84例年龄和性别匹配的对照组。参与者完成了中文版的口腔行为检查表（OBC）和成人饮食行为问卷。结果：TMD患者表现出明显更高的清醒状态口腔行为和总体OBC评分。回归分析显示，高OBC分级与tmd相关。具体的行为——没有牙齿接触的肌肉紧张，睡觉时压着下巴，以及单侧咀嚼——都有明显的联系。食欲性状无显著相关性。结论：口腔行为，特别是没有牙齿接触的清醒状态肌肉紧张，与tmd密切相关，而食欲特征与tmd无关。行为评估和修正可能有助于TMD的管理。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
