The aim of this study was to evaluate the therapeutic effect of occlusal adjustment on symptoms and signs of craniomandibular disorders (CMD), including headaches, after 3 and 6 months. Fifty patients were selected and randomly assigned to a treatment (T) or a control (C) group. All patients in the treatment group were subjected to occlusal adjustment, whereas the controls were comforted only. Pre- and post-treatment assessment of subjective symptoms and clinical signs was made by a dentist not performing the occlusal adjustment. There was significant improvement in overall subjective symptoms within the T group at the 3- and 6-month follow-up visits, but a statistically significant difference between groups was found at the 3-month follow-up only. With regard to changes in frequency of facial pain a significant deterioration was reported within the C group, which resulted in a significant difference between groups at the 6-month follow-up. No other significant differences were found within or between groups at the follow-ups with regard to the variables investigated. In conclusion, the results from this study that occlusal adjustment is a treatment modality with a statistically significant short-term effect on symptoms of CMD of muscular origin and superior to counseling.
本研究的目的是评估咬合调整对颅下颌关节紊乱症（CMD）的症状和体征（包括头痛）在3个月和6个月后的治疗效果。选取了50名患者并随机分为治疗组（T）和对照组（C）。治疗组的所有患者均接受咬合调整，而对照组仅给予安慰。由未进行咬合调整的牙医对主观症状和临床体征进行治疗前和治疗后的评估。在3个月和6个月的随访中，T组的总体主观症状有显著改善，但仅在3个月随访时发现组间有统计学显著差异。关于面部疼痛频率的变化，C组报告有显著恶化，这导致在6个月随访时组间有显著差异。在随访中，就所研究的变量而言，组内或组间未发现其他显著差异。总之，本研究结果表明，咬合调整是一种对肌肉源性CMD症状有统计学显著短期效果且优于咨询的治疗方式。
