本研究的目的是评估个人正畸治疗前后颞下颌关节紊乱病（TMD）的患病率。样本包括200个人分为四组，根据类型的错（类I或II）和正畸治疗完成。一个回忆问卷，包括关于TMD最常见的症状的问题，被用来分类的样本根据TMD的存在和严重程度。进行临床检查，包括颞下颌关节和肌肉触诊，下颌关节活动范围和关节噪音分析。根据回忆问卷，34%的样本被认为是轻度TMD，而3.5%的样本被认为是中度TMD。女性TMD患病率较高。关节噪声（15.5%），其次是头痛（13%），构成了最常见的报告症状。TMD的存在和严重程度与正畸力学类型或拔牙方案没有任何关系。另一方面，一个积极的关联被发现之间的TMD和功能失调的习惯和报告的情绪紧张。正畸治疗与TMD的体征和症状的存在无关。
The aim of this study was to evaluate the prevalence of temporomandibular disorders (TMD) in individuals before and after orthodontic treatment. The sample comprised 200 individuals divided into four groups according to the type of malocclusion (class I or II) and the orthodontic treatment accomplished. An anamnestic questionnaire, comprising questions regarding the most frequent symptoms of TMD, was used to classify the sample according to the TMD presence and severity. A clinical examination, including TMJ and muscle palpation, mandibular range of motion, and joint noise analysis was performed. Based on the anamnestic questionnaire, 34% of the sample was considered as having mild TMD, whereas 3.5% had moderate TMD. A higher TMD prevalence was found in females. Joint noises (15.5%) followed by headache (13%) constituted the most frequent reported symptoms. The presence and severity of TMD have not shown any relationship with either the type of orthodontic mechanics or extraction protocols. On the other hand, a positive association was found between TMD and parafunctional habits and reported emotional tension. Orthodontic treatment is not associated with the presence of signs and symptoms of TMD.
