Fifty patients were selected according to age (less than 40 years) and dentition (full complement of natural teeth) from a large group referred for treatment of functional disturbances of the masticatory system. They answered a questionnaire and were examined clinically for evaluation of the severity of their symptoms and signs according to the Helkimo dysfunction indexes. The occlusal conditions recorded included contacts in centric and eccentric mandibular positions, various defined occlusal patterns, occlusal interferences, and dental attrition. The occlusal conditions varied considerably but did not show significant correlations with signs and symptoms of mandibular dysfunction. These results suggest that the occlusal variables studied do not contribute to the severity of the signs and symptoms of dysfunction. While it is tempting to propose that our results suggest an argument for dysfunction, it must be admitted that the precise role of occlusion remains unclear.
从一大群因咀嚼系统功能紊乱前来治疗的患者中，根据年龄（小于40岁）和牙列情况（天然牙列完整）选取了50名患者。他们回答了一份问卷，并根据Helkimo功能障碍指数接受了临床检查，以评估其症状和体征的严重程度。记录的咬合情况包括下颌正中位和非正中位的接触、各种明确的咬合模式、咬合干扰和牙齿磨损。咬合情况差异很大，但与下颌功能障碍的体征和症状没有显著相关性。这些结果表明，所研究的咬合变量对功能障碍体征和症状的严重程度没有影响。虽然很容易认为我们的结果为功能障碍提供了论据，但必须承认，咬合的确切作用仍不清楚。
