摘　　要：牙体、牙列形态及咬合关系的研究对于指导口腔临床医学及人类学的研究均有一定的帮助。作者对中、日两所医科大学学生的牙体、牙列形态及咬合关系进行了多项目的综合调查，本文就Ｃａｒａｂｅｌｌｉ尖的研究作一报道，调查结果显示：（１）Ｃａｒａｂｅｌｌｉ尖日本的发生率高于中国，两国的男性发生率明显高于女性；（２）Ｃａｒａｂｅｌｌｉ尖在上颌第一磨牙中双侧发生率极高；（３）Ｃａｒａｂｅｌｌｉ尖的发生率与身高及牙尖数目类型有一定的关系。说明Ｃａｒａｂｅｌｌｉ尖的发生与人种、个体差异、牙齿的发育状况均是有关联的。Abstract The study of teeth,dentition and occlusion is helpful to guide oral medical clinic and the study of anthropology.Our department cooperated with Oral Anatomy Department of Osaka Dental University and had many items of reserch work about teeth, dentition and occlusion between Chinese and Japanese students. This article reports the study of Carabelli cusp.The results revealed:(1)the rate of Carabelli cusp is higher in Japanese than in Chinese and is higher in male than in female. (2)the rate of Carabelli cusp of the first maxillary molar of both side is very high. (3)The rate of Carabelli cusp is related to the height and the type of cusp numbers.These all illustrated the occurence of Carabeiil cusp were influenced by race , individual and the development of teeth.
