The prevalence of taurodontism was studied radiographically in 1,200 young adult Israeli patients. In order to differentiate taurodont teeth from normal teeth, three types of taurodontism (meso-, hypo- and hypertaudodontism) were defined in biometric terms, using radiographic features of molar morphology. All three types according to Shaw's classification were seen. Taurodontism was found to occur in 5.6% of 1,200 individuals and in 1.5% of the 10,204 molar teeth examined. The mandibular second molar was found to be the most prone, being involved in two thirds of all cases found. Hypertaurodontism was found only in three cases, in the third molars. The conditions was seen to involve single and multiple teeth, both unilaterally and bilaterally, with the latter being most predominant.
对1200名以色列年轻成年患者的牙齿进行了X线摄影研究，以了解牛牙症的患病率。为了区分牛牙症牙齿与正常牙齿，利用磨牙形态的X线特征，从生物测量学角度定义了三种类型的牛牙症（中型、低型和高型牛牙症）。根据肖氏分类法的所有三种类型均有发现。在1200名个体中，发现牛牙症的发生率为5.6%；在检查的10204颗磨牙中，发生率为1.5%。发现下颌第二磨牙最易受累，在所有病例中有三分之二涉及该牙。仅在3例第三磨牙中发现了高型牛牙症。该病症可见于单颗牙和多颗牙，单侧和双侧均有，其中双侧受累最为常见。
