牛牙症是一种髓腔的根尖部扩张的疾病,其结果造成在牙列中牙根相应的变短,而髓腔变大。本文报告了一例年轻男性黑人牛牙症患者,并描述了怎样发现牛牙症的,从而诊断出克莱恩费尔特氏综合症(Klinefelter's Syn-drome)。文献回顾:1931年Keith 在研究尼安德特人颅骨(Neanderthal Skull)时将牙体变大而牙根结构减少的多根牙命名为牛牙症,并认为其形式和结构上类似于反刍咀嚼的有蹄动物的磨牙。Shaw 将本症命名为低度的牛牙症、中度的牛牙症和高度的牛牙症三个亚纲。Kallay描述了一种与本症牙齿有关的单根楔状磨牙作
Stomatitis is a disease of apical dilatation of the medullary cavity, which results in a corresponding shortening of the root in the dentition and a greater medullary cavity. This article reports on a case of young male black dentin and describes how to detect bovine tooth disease to diagnose Klinefelter's Syn-drome. Literature review: In 1931, when studying the Neanderthal Skull, Keith named multiple teeth with enlarged teeth and reduced root structure as stomatitis, and considered it to be similar in form and structure to crooked chewing Molar teeth of hoofed animals. Shaw named the disease “low grade”, “standard” and “high”. Kallay describes a single wedge-shaped molars associated with the tooth
