ÖZET
Amaç: Bu çalışmanın amacı, mandibular kanalın anatomik yerleşimini ve radyografik seyrini araştırmak, klinik önemini tartışmak ve ayrıca mandibular kanalın pozisyonu ile hastaların yaşı ve cinsiyeti arasındaki olası korelasyonları belirlemektir. Gereç ve Yöntemler: Bu retrospektif çalışmaya, 90 konik ışınlı bilgisayarlı tomografi (KIBT) görüntüsü (52 kadın ve 38 erkek) dâhil edilmiştir. Mandibular kanalın pozisyonu üç farklı bölgede değerlendirilmiştir. Birinci molar bölge, mental foramenin en net izlendiği kesitin 10 mm posterioru olarak belirlendi. İkinci molar bölge, birinci molar bölgenin 10 mm posterioru ve üçüncü molar bölge, ikinci molar bölgenin 10 mm posterioru olarak belirlendi. Her üç bölgede, mandibular kanalın bukkal ve lingual kortikal kemiğe olan uzaklığı ile birlikte kanalın alveolar kret tepesine ve mandibula alt kenarına kadar olan en kısa doğrusal mesafeler (mm) ölçülerek kaydedildi. Bulgular: Tüm hastalar birlikte değerlendirildiğinde mandibular kanalın en fazla üçüncü bölgede lokalize olduğu saptanmıştır. Sonuç: Mandibular kanalın pozisyonunun belirlenmesi, özellikle cerrahi prosedürler sırasında güvenli tedavi planlaması yapılmasına ve dolayısıyla inferior alveolar sinire gelebilecek hasarın önlenmesine yardımcı olacaktır.

ABSTRACT
Objective: The purpose of the present study was to investigate the anatomic location and radiographic course of the mandibular canal and to discuss its clinical significance and also to determine the possible correlations between the mandibular position and the age of the patients. Material and Methods: This retrospective study was conducted on 90 CBCT of patients (52 females and 38 males). The location of canal was evaluated in 3 different regions. The first molar region was considered as the region, 10 mm posterior to the section on which the mental foramen could clearly be observed. The second molar region considered as the region 10 mm posterior to first molar region and the third molar region considered as the region 10 mm posterior to second molar region. On these sections, the shortest linear distances (mm) from the most buccal and lingual aspects of the canal to the corresponding cortical plates of the mandible and also the minimum linear distance between the inferior aspect of canal to inferior border of mandible and the superior aspect of canal to alveolar crest in these regions were calculated. Results: Considering all patients, the location of mandibular canal was higher in the third zone. Conclusion: Determination of the position of the mandibular canal will help to ensure safe treatment planning, especially during surgical procedures, and thus prevent damage to the inferior alveolar nerve.
