In the present study the degree of density of three anatomic regions in 215 orthopantomographs was evaluated. The three anatomic regions which were selected were: the maxillary sinus, the hard palate and the hard tissues (enamel and dentin) of the right lower first molar. The degree of density was correlated with the age and sex of the patients and it was found to increase with the age. The difference of the density was found to be statistical significant between the decade 1-10 compared to the other decades of age. The degree of density was greater in the women in all three anatomic regions but statistical significant only in the first molar region and in the decades 1-10 and 31-40.
在本研究中，对215张曲面体层摄影片中三个解剖区域的密度程度进行了评估。所选择的三个解剖区域为：上颌窦、硬腭以及右下第一磨牙的硬组织（牙釉质和牙本质）。密度程度与患者的年龄和性别相关，并且发现其随年龄增长而增加。与其他年龄段的十年相比，1至10岁这十年间的密度差异具有统计学意义。在所有三个解剖区域中，女性的密度程度更高，但仅在第一磨牙区域以及1至10岁和31至40岁这两个年龄段具有统计学意义。
