Analysis of temporomandibular joints sounds may contribute to the differential diagnosis of temporomandibular joint disorders. In this article an advanced system for the recording of joint sounds is presented. The method proved to be reliable. The problem of filtering out artifacts has been solved to a great extent but not completely. Temporomandibular joint sounds measured with this technique vary considerably in energy, frequency spectrum, and peak-to-peak amplitude over 3 months, as well as within 1 day. These differences seem to reflect natural variations in joint sounds caused by the physical impossibility of performing identical jaw movements. The results indicate that joint sound characteristics do not yet offer a solid basis for inferences concerning the development of temporomandibular joint abnormalities in the clinical setting.
颞下颌关节声音分析可能有助于颞下颌关节紊乱病的鉴别诊断。本文介绍了一种先进的关节声音记录系统。该方法被证明是可靠的。尽管在很大程度上解决了滤除伪迹的问题，但尚未完全解决。用该技术测量的颞下颌关节声音在3个月内以及1天内，其能量、频谱和峰峰值幅度都有很大差异。这些差异似乎反映了由于无法进行完全相同的下颌运动而导致的关节声音的自然变化。结果表明，在临床环境中，关节声音特征尚未为推断颞下颌关节异常的发展提供坚实的基础。
