The aim of the study was to investigate any correlation between tactile sensation and occlusal loading conditions of mandibular premolars and molars, by means of tactile detection threshold (TDT). TDTs of mandibular premolars and molars of twenty adults were determined by calibrated monofilaments. Occlusal force (OF) applied on each tooth at maximal-clenching was measured by a pressure-sensitive film. There was neither a correlation between the mean TDTs and the total OFs of individual participant nor in each tooth type. TDTs of the teeth on the preferred chewing side were significantly higher than those of the contralateral side. The results suggest that periodontal sensation is more related to frequency than to magnitude of loading.
本研究旨在通过触觉检测阈值（TDT）来研究下颌前磨牙和磨牙的触觉与咬合负荷条件之间的任何相关性。使用校准的单丝确定了二十名成年人的下颌前磨牙和磨牙的 TDT。通过压敏胶片测量了最大咬合时每个牙齿上的咬合力（OF）。个别参与者的平均 TDT 与总 OF 之间，以及每种牙齿类型之间均无相关性。偏侧咀嚼侧牙齿的 TDT 明显高于对侧。结果表明，牙周感觉与加载的频率更相关，而与幅度无关。
