Taurodontism leads to constriction of the cementoenamel junction, which results in vertically elongated pulp chambers, apical displacement of the pulpal floor, and bifurcation or trifurcation of the root. This trait can be seen in permanent and primary teeth, in a single tooth or in several molars in the same quadrant, and can be unilateral or bilateral. We report a rare case of a 26-year-old male patient presening with taurodontism involving all the developed molars of all four quadrants, which was not associated with any other anomalies or syndromes.
牛牙样牙症会导致牙骨质牙釉质界狭窄,进而造成牙髓腔垂直拉长、髓室底向根尖移位以及牙根分叉或三叉化。这种特征在恒牙和乳牙中都可见,可出现在单颗牙齿或同一象限的多颗磨牙中,并且可以是单侧或双侧的。我们报告了一例罕见病例,一名26岁男性患者,其所有四个象限已萌出的磨牙均患有牛牙样牙症,且未伴有任何其他异常或综合征。
