Abstract
Geç Bizans Dönemine ait (13 Y.Y.) 68 yetişkin erkek mandibulası üzerinde foramen mentalenin sayısı, ekli, çapları, mandibula'nın ön, arka ve alt kenarına olan uzaklıkları saptandı. For. mentale % 92.65 oranda tek ve % 7.35 oranda çift bulundu. Şekli çoğunlukla ovaldi. Yatay plandaki çapı genellikle daha uzun olup, çap uzunlukları 1-3 mm arasındaydı. For. mentale'nin mandibula'nın alt ve üst kenarları arasında tam ortada yer almadığı ve alt kenara daha yakın yerleştiği görüldü. Sağ tarafta bulunan for. mentale sola göre daha alttaydı (p < 0.05). Bu deliğin symphysis mentalis ile ramus mandibulaenin arka kenar arasındaki uzaklığın yaklaşık 1/4'lük ön bölümü ile 3/4'lük arka bölümü arasında yer aldığı belirlendi.
The main characteristics of the mental foramen examined were: 1) number, 2) shape, 3) dimensions, 4) the distance from the most anterior position of the anterior border of the foramen to the midline (mandibular symphysis), 5) the distance from the most anterior position of the anterior border of the foramen to the point on the posterior border of the ramus and 6) the distance from the most inferior position of the foramen to the point on the inferior border of the corpus. Measurements were performed on 68 dry mandibles (in adult men) belonging to the late Byzantine period ( 13 th century). 92.65 percent of mental foramina were single and 7.35 percent of mental foramina were double. The shape of mandibles were usually oval. In most cases, the long axis of the oval fornarina is laid horizontally. The diameters of foramina were between 1-3 mm. In our study, the mental foramina were located somewhat lower than halfway between the superior and inferior borders of the mandibles. The mental foramen on the right were significantly lower than the left (p < 0.05). It was found the mental foramina were located approximately at one-fourth distance from the mandibular symplıysis to the posterior border of the ramus. When our findings were compared to the findings of the other ethnic groups, there were no significant differences between our findings and the findings of other ethnic groups.
