Nobel Tongue Function Diagnosis Based on Age-specific Maximum Tongue Pressure Standard Value

本研究的目的是建立一种新的方便的舌功能诊断的基础上的年龄特异性标准值的最大随意舌压（MVTP）。在将一次性口腔内探头和便携式设备组装成实用系统后，我们可以在流行病学研究情况下假设的各种环境中测量舌压，我们测量了1，229名志愿者的MVTP（年龄范围：受试者人数：18 - 39岁：311，40 - 59岁：99，60 - 79岁：429，80岁及以上：390），经广岛大学牙科学院伦理委员会许可。除了MVTP测量外，还对受试者的口腔状态和咀嚼/吞咽功能进行检查和访谈，包括重复唾液吞咽试验（RSST）。对于没有吞咽功能障碍体征和症状的受试者，MVTP的平均值± S.D.各年龄组的平均压力分别为：18-39岁：42 ± 11kPa，40-59岁：39 ± 12kPa，60.79岁：32 ± 11kPa，80岁及以上：23 ± 11kPa。年龄与MV'I 'P呈负相关，对于GO岁以上的受试者，RSST吞咽3次及以上者MVTP较强（29 ± 12 kPa），吞咽次数少于3次者，（21 ± 12 kPa）总之，根据本研究领域迄今为止最大样本获得的年龄特异性标准值，尽管从有限的方面来看，可以方便、安全地对舌功能中涉及吞咽功能的一些定量方面进行诊断

The purpose of this study was to establish a novel handy tongue function diagnosis based on age-specific standard value of maximum voluntary tongue pressure (MVTP). After assembling utility system with disposable intra-oral probe and portable devices that enables us to measure tongue pressure in diversified environments supposed in such as epidemiologic study situation, we measured MVTP of 1,229 volunteers (age range : number of subjects 18-39 yr : 311, 40-59 yr : 99, 60-79 yr : 429, 80 yr and over : 390) under the permission of Hiroshima University School of Dentistry Ethical Committee. Besides MVTP measurement, subjects were inspected and interviewed about oral status and chewing/swallowing function including Repetitive Saliva Swallowing Test (RSST)For subjects w ho had no signs and symptoms of swallowing dysfunction, MVTP's mean±S.D. for each age brackets were as follows 18-39 yr : 42±11 kPa, 40-59 yr : 39±12 kPa, 60.79 yr : 32±11 kPa, 80 yr and over : 23±11 kPa. There was negative correlation between age and MV'I'P. For subjects over GO years of age, those who could swallow 3 and more times in RSST could exert stronger MVTP (29 ± 12 kPa) than those who could swallow less than 3 times could (21±12 kPa)In conclusion, based on age specific standard value acquired from the largest sample ever in this field of study, although from the limited aspect, we could diagnose some quantitative aspects of tongue function concerning swallowing function conveniently and safely
