Abstract

Objectives

Tactile acuity is a somatosensory measure of the extent to which humans can discern tactile stimuli. It is influenced by how peripheral signals are processed centrally. In the oral cavity, Occlusal Tactile Acuity (OTA) is the ability to perceive minimal thicknesses between antagonist teeth. The aim of the current study was to assess the association between psychological traits and OTA of otherwise healthy individuals.

Methods

Sixty-three volunteers (32 males; mean age ± SD: 24.6 ± 2.7 years) participated in this study. Somatosensory amplification, anxiety, depression, physical symptoms and pain catastrophizing were scored using questionnaires, and subgroups of severity were created per variable based on cut-offs. OTA was measured using 9 aluminium foils with thickness (ranging from 8 to 72 μm) and one sham test (without foil). Each thickness was tested 10 times in random order, the participants were instructed to report whether they felt the foil between their molars and the mean percentage of correct answers was computed. A linear mixed model was used with OTA as a dependent variable and psychological domain as an independent variable.

Results

Significantly different OTA was observed among the anxiety subgroups (p = .003), supporting a decreased perception of thicknesses 24 and 32 μm (p = .018 and p < .001, respectively) in participants with moderate/severe anxiety compared to those with no/mild anxiety. Significantly different OTA was also observed among the pain catastrophizing subgroups (p = .008), showing decreased perception of thicknesses 32 and 40 μm (p < .001 and p = .007, respectively) in severe catastrophizing levels, compared to no/mild catastrophizing levels. No significant differences were observed for the other variables.

Conclusions

Healthy adults with increased anxiety or pain catastrophizing levels show decreased interdental acuity as compared to participants with minor or no psychological impairment.

健康人的心理特征与咬合触觉敏锐度之间的关系。

目标触觉敏锐度是一种体感测量方法，用于衡量人类对触觉刺激的分辨能力。它受中枢如何处理外周信号的影响。在口腔中，咬合触觉敏锐度（OTA）是指感知拮抗牙之间最小厚度的能力。本研究旨在评估健康人的心理特征与咬合触觉敏锐度之间的关系：63名志愿者（32名男性；平均年龄（± SD）：24.6±2.7岁）参加了此次研究。通过问卷对躯体感觉放大、焦虑、抑郁、躯体症状和疼痛灾难化进行评分，并根据临界值对每个变量的严重程度进行分组。测量 OTA 时使用了 9 种厚度（从 8 微米到 72 微米不等）的铝箔和一种假测试（不使用铝箔）。每种厚度随机测试 10 次，要求参与者报告是否感觉到臼齿间的铝箔，并计算正确答案的平均百分比。采用线性混合模型，以 OTA 为因变量，心理领域为自变量：结果：在焦虑亚组中观察到明显不同的 OTA（p = .003），支持对 24 和 32 μm 厚度的感知下降（p = .018 和 p 结论：焦虑或疼痛增加的健康成人对臼齿之间的金属箔的感知下降：焦虑或疼痛灾难化程度增加的健康成年人与心理障碍轻微或无心理障碍的参与者相比，牙间隙敏锐度有所下降。

期刊介绍： Journal of Oral Rehabilitation aims to be the most prestigious journal of dental research within all aspects of oral rehabilitation and applied oral physiology. It covers all diagnostic and clinical management aspects necessary to re-establish a subjective and objective harmonious oral function. Oral rehabilitation may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial traumas, or a variety of dental and oral diseases (primarily dental caries and periodontal diseases) and orofacial pain conditions. As such, oral rehabilitation in the twenty-first century is a matter of skilful diagnosis and minimal, appropriate intervention, the nature of which is intimately linked to a profound knowledge of oral physiology, oral biology, and dental and oral pathology. The scientific content of the journal therefore strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence gathered about diagnostic procedures and the properties and efficacy of the chosen intervention (e.g. material science, biological, toxicological, pharmacological or psychological aspects). The content of the journal also reflects documentation of the possible side-effects of rehabilitation, and includes prognostic perspectives of the treatment modalities chosen.
