结果表明，由于受试者、患者的临床状态、下颌运动类型和特定运动轴的不同，TMJ声音的频谱有显著差异。我们认为，其中一些差异是由关节的较大或较小组件结构的运动引起的。显然，要将声谱的特定特征与解剖和临床信息相关联，还需要进行大量的额外工作。在今后的工作中，我们计划结合核磁共振成像对关节进行声谱分析记录。这样的数据将使我们能够识别与关节中的特定结构或在颌骨运动期间发生的事件相关的特定频带，例如，由于髁突/半月板关系的突然变化而产生的运动。一旦获得了这样的基线信息，就可以对特定的个体受试者进行一段时间的随访，以确定治疗的效果。我们希望特定频段的变化可以作为特定治疗效果的量化指标。除了从这种定量信息中为牙医提供指导外，由此获得的颌骨关节状况的永久定量记录可能对临床和法律目的都有价值。
Results demonstrated significant differences in the spectra of TMJ sounds due to differences in subject, in patients' clinical status, type of jaw movement, and specific axis of motion. We suggest that some of these differences are caused by motion of larger or smaller component structures of the joint. It is apparent that significant additional work is needed to correlate specific features of the sound spectra with anatomic and clinical information. In future work, we plan to do sound spectral analysis recording in conjunction with nuclear magnetic resonance imaging of the joint. Such data will allow us to identify specific frequency bands that correlate with specific structures in the joint or events occurring during the jaw motion, for example, the motion produced by a sudden change in the condyle/meniscus relationship. Once such baseline information is obtained, specific individual subjects can be followed up over a period of time to determine the effects of treatment. We hope that changes in specific frequency bands can be used as quantitative indices of the results of specific treatments. In addition to the guidance afforded the dentist from such quantitative information, a permanent quantitative record of the jaw joint status thus obtained could be of value for clinical as well as legal purposes.
