OBJECTIVE
To investigate the role of occlusion in temporomandibular disorders (TMDs) in the Northern Finland Birth Cohort 1966 (NFBC 1966).
METHODS
Subjects ( = 1962) participated in clinical medical and dental examinations. The association between TMD signs and diagnoses with occlusal disturbances, i.e. malocclusions and occlusal interferences, was examined. Pearson's chi-square test, as expressed by odds ratios (OR) and 95% confidence intervals (CI) and logistic regression models, were used in the analysis.
RESULTS
A statistically significant association was found between myalgia and lateral scissor bite and also between arthralgia and lateral deviation in the retruded contact position and intercuspal contact position (RCP-ICP) slide. Pain in the masticatory muscles was associated with negative overjet and the amount of RCP-ICP slide.
DISCUSSION
Occlusal factors showed a statistically significant association with TMD. The TMD signs were associated with unstable occlusion, especially the amount and lateral deviation in RCP-ICP slide, as well as negative overjet.
目的
在1966年芬兰北部出生队列（NFBC 1966）中研究咬合在颞下颌关节紊乱病（TMDs）中的作用。
方法
1962名受试者参加了临床医疗和牙科检查。研究了TMD体征和诊断与咬合干扰（即错牙合和咬合干扰）之间的关联。分析中使用了Pearson卡方检验，以比值比（OR）和95%置信区间（CI）表示，并采用了逻辑回归模型。
结果
发现肌痛与侧剪式咬合之间以及关节痛与后退接触位和牙尖交错接触位（RCP - ICP）滑动中的侧方偏斜之间存在统计学显著关联。咀嚼肌疼痛与前牙深覆盖负值以及RCP - ICP滑动量有关。
讨论
咬合因素与TMD存在统计学显著关联。TMD体征与不稳定咬合有关，尤其是RCP - ICP滑动的量和侧方偏斜，以及前牙深覆盖负值。
