The purpose of the present investigation was to determine the relationship between oral parafunctions and the development of temporomandibualr disorders (TMD). A group of 1,976 children aged 3-15 years old, were randomly selected and underwent an examination that consisted of palpation and assessment of the temporomandibular joints and associated muscles for tenderness and joint sounds. Maximum vertical opening and deviation during jaw opening were also recorded. The parents were requested to complete a questionnaire contained questions regarding symptoms of TMD and history of oral parafunctions. Results showed significant correlations between cheek biting, nail biting, bruxism, thumb sucking and most of TMD signs and symptoms. The results of the study support the concept that oral parafunctions have a significant role in the aetiology of TMD and should be tackled by the paediatric dentists to minimise their effects on the stomatological system.
本研究的目的是确定口腔副功能与颞下颌关节紊乱病（TMD）发展之间的关系。随机选取了一组1976名3至15岁的儿童，对他们进行了检查，包括触诊和评估颞下颌关节及相关肌肉的压痛和关节弹响。同时记录了最大垂直开口度和张口时的偏斜情况。要求家长填写一份问卷，其中包含有关TMD症状和口腔副功能病史的问题。结果显示，咬脸颊、咬指甲、磨牙症、吮拇指与大多数TMD体征和症状之间存在显著相关性。该研究结果支持这样一种观点，即口腔副功能在TMD的病因学中具有重要作用，儿科牙医应加以处理，以尽量减少其对口腔系统的影响。
