Abstract (2. Language): 
The aim of this study was to evaluate the variation of the anatomical landmarks at interforaminal region with age and dental status by examining spiral computed tomographies. Fifty young (≤40) and 50 older (>40) patients’ interforaminal regions were evaluated with spiral computed tomographic images. In both age groups, 25 of the patients were fully dentate up to mandibular bicuspids contralaterally and the rest were completely edentate at interforaminal region including mandibular bicuspids. The distances between mental foramen to alveolar crest (MF-AC), mental foramen to lower cortex (MF-LC), mental foramen to lingual external border (MF-LEB), mental foramen to contralateral mental foramen (MF-MF), and the height (HMF) and width of MF (WMF) and anterior loop of mental foramen (ML) were measured by an experienced calibrated clinician. In spiral computed tomographic images, MF-AC and MF-LC were significantly lower in edentate subjects being independent of age (p<0.001). WMF and HMF were found significantly smaller in both older and edentate subject groups (p<0.01), MF-MF was significantly longer (p<0.001) in both edentate and older patients, and MF-LEB was not affected by age or dental status (p>0.05). The anatomical landmarks at interforaminal region more likely depend on dental status rather than the age. Safety zone should be 3 mm far from MF for dental implant placement in interforaminal region as the anterior loop of mental foramen was measured as approximately 3 mm

Abstract (Original Language): 
Bu çalışmanın amacı, interforaminal bölgedeki anatomik noktaların, yaş ve dişsel durumları ile ilişkilerinin spiral bilgisayarlı tomografi ile değerlendirilmesidir. Kırk yaş altı ve 40 yaş üstü ellişer hastanın interforaminal bölgeleri spiral bilgisayarlı tomografi ile değerlendirildi. Her iki yaş grubunda da 25’er hasta mandibular azı dişlerine kadar kontralateral olarak tam dişli idi ve geri kalan 25’er hasta ise mandibular azı dişleri de dahil olmak üzere interforaminal bölgede total dişsizdi. Mental foramen-alveolar krest arası mesafe (MF-AC), mental foramen-alt korteks arası mesafe (MF-LC), mental foramen-lingual eksternal yüzey arası mesafe (MF-LEB), mental foramenler arası mesafe (MF-MF), mental foramenin dikey yüksekliği (HMF) ve yatay genişliği (WMF) ve mental foramenin öne doğru kıvrımı (ML), deneyimli bir klinisyen tarafından ölçüldü. Spiral bilgisayarlı tomografik incelememelerde MF-AC ve MF-LC, dişi olan hastalarda yaştan bağımsız olarak daha düşük değerlerde saptandı (p<0.001). WMF ve HMF hem yaşlı, hem de dişi olan gruplarda daha düşük olarak, MF-MF daha uzun olarak tespit edildi ve MF-LEB’nin yaş ve dişsel durumdan etkilenmediği saptandı (p>0.05). İnterforaminal bölgedeki anatomik oluşumlar yaştan daha çok dişsel duruma bağlıdır. Mental foramenin öne doğru kıvrımının, ortalama 3 mm olarak ölçülmesinden dolayı, bu bölgedeki implant uygulamalarının MF’den 3 mm uzakta yapılması daha güvenli olacaktır.
