Objectives : The sense of taste has been evaluated by putting some taste solutions and then by investigating the taste perceptive threshold. However, there have been few studies examining the spread of taste in the mouth, in terms of masticatory process. The purpose of this study was to develop a new gustatory test depending upon a quantitative evaluation of the spread of taste by counting the number of chewing strokes till recognizing the taste.Methods: 43 subjects without missing teeth (19 females and 24 males, mean age: 30.0 years) were selected for this study after obtainment of informed consent. Newly designed sample foods made from 3% agarose containing 2% or 5% sucrose were prepared. The subjects were instructed to chew the sample foods and the numbers of chewing strokes were measured till they recognize sweetness at either small area or whole area of their tongues. Five factors (masticatory perbrmance, salivary flow rate, gustatory test [filterpaper disk test], maximum bite force, scores of oral health related to quality of life [OHIP]) concerning the stomatognathic function were carried out to confirm their relationships with taste.Results: Male subjects exhibited larger numbers of chewing strokes to perceive taste than female subjects for 5% sucrose sample food. The numbers of chewing strokes for whole area of tongue or for 2% sucrose sample food were larger than those for small area of tongue or for 5% sucrose sample food, respectively. Moreover, for some experimental conditions, numbers of chewing strokes were significantly associated with masticatory performance (Spearman's correlation coefficient by rank test: rs=0.49), salivary flow rate (rs=-0.53), maximum bite force (rs=-0.43) and scores of OHM (rs4144-〜0.66).Conclusion : The findings suggested that our new gustatory test would be useful to clarify the taste sensation.

目的：通过放置不同浓度的味觉溶液，观察味觉感知阈值的变化。然而，很少有研究检查口腔中的味道传播，在咀嚼过程方面。本研究的目的是开发一种新的味觉测试依赖于定量评价的传播的味道通过计数的咀嚼中风，直到识别taste.Methods的数量：43例无缺牙（19名女性和24名男性，平均年龄：30.0岁）被选为本研究后，获得知情同意书。新设计的样品食品由含有2%或5%蔗糖的3%琼脂糖制成。受试者被要求咀嚼样品食物，并测量咀嚼次数，直到他们在舌头的小区域或整个区域识别甜味。5个因素（咀嚼效能，唾液流量，味觉测试[滤纸盘测试]，最大咬合力，口腔健康相关的生活质量评分[OHIP]）有关的口颌功能进行了确认其与taste.Results的关系：男性受试者表现出更多的咀嚼中风比女性受试者感知的味道为5%的蔗糖样品食物。整个舌头区域或2%蔗糖样品食物的咀嚼次数分别大于小面积舌头或5%蔗糖样品食物的咀嚼次数。此外，在某些实验条件下，咀嚼次数与咀嚼性能显著相关（秩检验的斯皮尔曼相关系数：rs=0.49），唾液流速（rs=-0.53），最大咬合力结论：新的味觉测试方法对味觉的研究具有一定的参考价值。
