OBJECTIVES
To assess the prevalence of taurodontism in a group of Jordanian adult dental patients.
METHODS
Posterior periapical radiographs of 875 unselected dental patients were examined for the presence of taurodontism defined as the presence of an apically displaced pulp chamber without the usual constriction at the cemento-enamel junction.
RESULTS
Taurodontism was detected in 8% of subjects and 4.4% of the teeth examined. The maxillary second molar was the most commonly affected tooth. It was equally distributed between males and females (7.9% compared with 8.1% respectively, P > 0.05). 26.7% of the taurodont teeth also had pulp stones or calcifications.
CONCLUSION
Taurodontism is not uncommon in Jordan but further larger scale studies are required to assess its prevalence in the general population to compare it with other ethnic groups.
目的
评估一组约旦成年牙科患者中牛牙症的患病率。
方法
对875名未经挑选的牙科患者的根尖后位X线片进行检查，以确定是否存在牛牙症，牛牙症定义为牙髓腔向根尖移位且在牙骨质-釉质界处无通常的缩窄。
结果
在8%的受试者和4.4%的检查牙齿中检测到牛牙症。上颌第二磨牙是最常受影响的牙齿。在男性和女性中分布均等（分别为7.9%和8.1%，P>0.05）。26.7%的牛牙症牙齿还伴有髓石或钙化。
结论
牛牙症在约旦并不罕见，但需要进一步进行更大规模的研究，以评估其在普通人群中的患病率，并与其他种族群体进行比较。
