Stereognosis has been defined as the appreciation of the form of objects by palpation. Whilst this definition holds good for the manual exploration of objects, it is possible for the shape of objects to be explored intra orally referred to as oral stereognosis. To better understand patients' relative satisfaction with complete dentures, differences in oral stereognostic perception, based on the identification of 6 edible objects was analyzed in a group of 30 edentulous individuals at 3 stages, namely, just before (pre-treatment), 30 min after (30 min post-treatment) and 1 month after (1 month post-treatment) the insertion of new dentures. The time required to identify each object was recorded and the correctness of identification of each object was scored using oral stereognostic score. Descriptive statistics, Wilcoxon signed rank test, Spearman's rank correlation test, Pearson Chi square test was used to statistically analyze the data obtained. OSA scores was significantly increased 1 month post-treatment compared to 30 min post-treatment (p < 0.05). It was found that Oral stereognostic test is reliable for measuring patients' oral stereognostic perception and may be used as one of the clinical aids in appreciating the functional limitations imposed by the prostheses.
实体觉被定义为通过触诊来感知物体的形状。虽然这个定义适用于对手部触摸物体的情况，但物体的形状也可以通过口腔内进行探索，这被称为口腔实体觉。为了更好地了解患者对全口义齿的相对满意度，对一组30名无牙颌个体在三个阶段进行了分析，这三个阶段分别是：刚佩戴新义齿前（治疗前）、佩戴后30分钟（治疗后30分钟）和佩戴后1个月（治疗后1个月），基于对6种可食用物体的识别来分析口腔实体觉感知的差异。记录识别每个物体所需的时间，并使用口腔实体觉评分对每个物体的识别正确性进行评分。使用描述性统计、Wilcoxon符号秩检验、Spearman秩相关检验、Pearson卡方检验对获得的数据进行统计分析。与治疗后30分钟相比，治疗后1个月时口腔实体觉评分显著提高（p<0.05）。研究发现，口腔实体觉测试对于测量患者的口腔实体觉感知是可靠的，并且可以用作评估假体所造成功能限制的临床辅助手段之一。
