This study was performed to determine the position of the mental foramen relative to the apices of the teeth based on panoramic radiographs in a Moroccan population. We also analyzed gender differences and the symmetry of location within individuals.
Seven hundred ninety-four panoramic radiographs were evaluated with regard to the location and symmetry of the mental foramina in male and female subjects. The results were analyzed using Pearson's χ(2) and Fisher's exact test.
Of the 794 panoramic radiographs, 377 met the inclusion criteria for at least one side. The mental foramen was located just below the apex of the second premolar in 62.7% of the patients and between the first and second premolars in 30%. It was symmetrically located in 79%. No statistically significant differences were found between males and females in the position and symmetry of the mental foramen.
The most common position for the mental foramen in this sample was in line with the second premolar.
本研究旨在根据摩洛哥人群的全景X线片确定颏孔相对于牙齿根尖的位置。我们还分析了性别差异以及个体内部位置的对称性。
对794张男性和女性受试者的全景X线片进行颏孔位置和对称性评估。结果采用Pearson卡方检验和Fisher精确检验进行分析。
在794张全景X线片中，377张至少一侧符合纳入标准。62.7%的患者颏孔位于第二前磨牙根尖正下方，30%位于第一和第二前磨牙之间。79%的颏孔位置对称。颏孔的位置和对称性在男性和女性之间未发现统计学显著差异。
该样本中颏孔最常见的位置与第二前磨牙一致。
