对100名身体正常的爱荷华州西北欧血统的9岁儿童的Carabelli's结节的发生、大小和双侧性进行了研究。基本数据是对牙结石的对照观察，即，上颌第一恒磨牙近中舌侧牙尖舌面的观察。200颗第一磨牙中84%有amt。的补充性突起。约60%有中度至重度隆起，而16%没有任何可观察到的辅助隆起。13%的受试者在牙弓一侧没有出现辅助抬高，而在另一侧出现轻微至中度抬高。70%的受试者左右两侧的结节大小存在差异。
Study was made of the occurrence, size, and bilateralism of Carabelli''s tubercle in 100 physically normal 9-yr-old Iowa children of Northwest European ancestry. Basic data were controlled observations on dental ecasts, e.i., observations of the lingual surfaces of the mesiolingual cusps of the permanent maxillary 1st molars. Eighty-four % of the 200 1st molars examined showed some amt. of supplemental protuberance. Approx. 60% had moderate to large prominences, while 16% lacked any observable accessory elevation. Thirteen % of the subjects exhibited no accessory elevation on one side of the arch and a slight to moderate elevation on the other. There was a difference in the size of the tubercle on the right and left sides for 70% of the subjects.
