ÖZET
 Amaç: Üst 1. büyük azı dişlerin meziobukkal kökünün bukkalindeki alveoler kemik dehisens ve apikal fenestrasyon prevalansının konik ışınlı bilgisayarlı tomografi (KIBT) ile araştırılmasıdır. Gereç ve Yöntemler: Gazi Üniversitesi Diş Hekimliği Fakültesi Ağız, Diş ve Çene Radyolojisi ABD'de rutin klinik incelemelerde Promaks 3D® (Planmeca, Helsinki, Finlandiya) cihazı ile maksillanın tamamının görüntülendiği 200 KIBT görüntüsü üzerinde yapılan değerlendirmelerde, 316 adet birinci büyük azı dişi tespit edilerek incelendi. Görüntüler cihazın orijinal programı olan Romexis® kullanılarak incelendi. Bukkal alveol kemik bölgesindeki "V'' şekilli defektler değerlendirildi. Dehisens belirlenen dişler tekrar iki boyutlu değerlendirmeye alındı. Elde edilen bulgular kategorize edildi. Bulgular: Dişlerin %10,75'inde bukkal alveoler kemik dehisensi görüldü. Total Sınıf Ⅰ defekt oranı %6,65, Sınıf Ⅱ defekt oranı %3,48, Sınıf Ⅲ defekt oranı %0,63 olarak bulundu. Apikal fenestrasyon oranı ise %1,26 idi. Sonuç: Diş hekimleri, endodontik tedavi sonrası devam eden ağrının, başarısız olan ve periodontal sorunların eşlik ettiği endodontik tedavilerin nedeni olarak üst birinci azı dişlerde meziobukkal kökün alveol kemiğinde dehisens ve apikal fenestrasyon görülme olasılığını özenle değerlendirmelidir.

ABSTRACT
 Objective: The aim of this study was to evaluate the prevalence of dehiscence and apical fenestration on mesiobuccal root region of upper first molar teeth using cone-beam computed tomography (CBCT). Material and Methods: Two hundred CBCT images from patients who received CBCT during routine examination were obtained from the Department of Oral Diagnosis and Radiology in Gazi University Faculty of Dentistry. CBCT images were produced at using a Promaks® 3D scanner (Planmeca, Helsinki, Finland). Finally, from a total of 200 patients 316 upper first molar teeth were obtained and evaluated. Image analysis was performed using the original software of scanner, Romexis® 2.7.0.R (Planmeca, Helsinki, Finland). "V'' shaped defects were analyzed in first molar buccal alveolar bone region. After a dehiscence was diagnosed, each root was evaluated in 2D cross sectional images. Findings were categorized. Results: Alveolar bone dehiscence was associated with 10.75% of all teeth. Class Ⅰ dehiscence rate was 6.65%, Class Ⅱ dehiscence rate was 3.48%, Class Ⅲ dehiscence rate was 0.63%. Apical fenestration rate was 1.26%. Conclusion: Dental practitioners should be aware that the possibility of the occurence of dehiscence and apical fenestration on alveolar plate of mesiobuccal root of maxillary first molar teeth should be evaluated for the predisposing factor of persistant pain after endodontic treatment and unsuccessful endodontic treatments accompanied by periodontal problems.
