The orientation of enamel prisms in mesio-distal plane was investigated in cervical tooth area in relation to the long axis. The X-ray diffraction method from successive planes of apatite-crystal lattice, nas used. Testings were done on mesial and distal tooth surfaces in four groups of human lateral teeth: maxillar premolars and molars and mandibular premolars and molars. According to the obtained results the apical orientation was the most frequent orientation in all investigated teeth (54-84%). Horizontal orientation of enamel prisms was found in 2-18% of cases and occlusal in 4-32% of teeth.
研究了牙颈部区域釉柱在近远中平面相对于牙长轴的方向。采用了磷灰石晶格连续平面的X射线衍射方法。对四组人类侧切牙（上颌前磨牙和磨牙以及下颌前磨牙和磨牙）的近中面和远中面进行了测试。根据所得结果，在所有被研究的牙齿中，根尖方向是最常见的方向（54% - 84%）。在2% - 18%的病例中发现釉柱呈水平方向，在4% - 32%的牙齿中呈咬合方向。
