Abstract

In the oral cavity, oral stereognosis and chemesthesis refer to the abilities to recognize shapes and detect noxious substances, respectively, through various receptors distributed on the tongue. The absence of standardized methods to assess oral somatosensory perception has led to a lack of consensus regarding the relationship between taste and trigeminal sensations. While some studies reported lower trigeminal perception in taste disorders, others did not confirm this correlation. In order to analyze somatosensation in quantitative and qualitative taste problems, 28 patients (21 females, mean age 59.2 years) with taste disturbance and 32 participants (20 females, mean age 42.3 years) with normogeusia identified 3D shapes and letters, sized from 2 to 18 mm, with the anterior part of their tongue, in a threshold test. Additionally, participants rated the intensity of increasing amounts of chili. Gustatory and olfactory functions were also tested. Analyses revealed that patients with taste dysfunction had significantly higher thresholds for lingual tactile sensitivity compared to controls (p < 0.001). Moreover, patients rated the intensity of chili significantly lower than controls (p < 0.001), particularly at higher concentrations. Oral stereognosis threshold scores were negatively correlated with gustatory and olfactory functions, and decreased with increasing age, while intensity for chili correlated with taste scores (p ≤ 0.009). The findings of this study suggest that taste dysfunction is associated with low oral mechanosensory and chemesthetic functions. The testing methods used in this study could be valuable in clinical practice for assessing and monitoring sensory impairments.

三叉神经感觉的味觉:味觉功能障碍患者味觉、舌触觉敏锐度与辛辣感知的关系。
在口腔中,口腔立体感知和口腔化学感知是指通过分布在舌头上的各种感受器分别识别形状和检测有害物质的能力。缺乏标准化的方法来评估口腔体感知觉导致缺乏共识关于味觉和三叉神经感觉之间的关系。虽然一些研究报告了味觉障碍的三叉神经感知能力较低,但其他研究并未证实这种相关性。为了分析定量和定性味觉问题中的体感觉,28例味觉障碍患者(21名女性,平均年龄59.2岁)和32例正常症患者(20名女性,平均年龄42.3岁)用舌头前部识别了大小为2 ~ 18mm的三维形状和字母。此外,参与者还对辣椒量增加的强度进行了评级。还测试了味觉和嗅觉功能。分析显示,味觉功能障碍患者的舌触觉敏感度阈值明显高于对照组(p < 0.001)。此外,患者对辣椒强度的评价明显低于对照组(p < 0.001),特别是在较高浓度的情况下。口腔立体视觉阈值评分与味觉和嗅觉功能呈负相关,且随年龄的增长而降低,而辣椒强度与味觉评分呈相关(p≤0.009)。本研究结果提示味觉功能障碍与口腔机械感觉和化学感觉功能低下有关。本研究所采用的测试方法在临床实践中对评估和监测感觉障碍具有重要价值。
