AB  - ObjectivesUnderstanding the root canal morphology of mandibular first premolars (M1Ps) is critical for effective endodontic treatment. This study aimed to evaluate the frequency and morphological variations of M1Ps in a retrospective sample from a Kazakh population using cone-beam computed tomography (CBCT).Material and MethodsA total of 600 M1Ps from 300 patients were analyzed using CBCT. Root number, canal configurations according to the Vertucci and Ahmed classifications, C-shaped canal morphology, radicular grooves, taurodontism, bilateral symmetry, and demographic variables were evaluated.ResultsThe majority of M1Ps exhibited a single root (93%), with 2-rooted teeth identified in 7% of cases; no 3-rooted forms were observed. Vertucci’s Type I (1-1) configuration was the most prevalent (72-74%), followed by Type V (1-2) in approximately 20% of cases, while Types II, III, and IV were rare (

N2  - AmaçBu çalışmanın amacı, Kazak popülasyonuna ait retrospektif konik ışınlı bilgisayarlı tomografi örnekleminde mandibular birinci küçük azı dişlerinin kök ve kanal morfolojisini değerlendirmektir.Gereç ve YöntemlerÇalışmada 300 hastaya ait toplam 600 mandibular birinci küçük azı dişi incelendi. Kök sayısı, kanal konfigürasyonları, bifurkasyon düzeyi, C-şekilli kanal varlığı, radiküler oluklar ve taurodontizm değerlendirildi. Kök kanal konfigürasyonları Vertucci ve Ahmed sınıflamalarına göre analiz edildi. Ayrıca yaş ve cinsiyet dağılımları kaydedildi.BulgularMandibular birinci küçük azı dişlerinin büyük çoğunluğu tek köklüydü (%93); iki köklü dişler olguların %7’sinde saptandı ve üç köklü form gözlenmedi. En sık görülen konfigürasyon Vertucci Tip I idi (%72-74), bunu yaklaşık %20 oranında Tip V izledi. Ahmed sınıflamasına göre en sık 1MP 1-1 konfigürasyonu görüldü. C-şekilli kanallar koronal üçlüde %17-18, orta üçlüde %27-28 ve apikal üçlüde yaklaşık %20 oranında tespit edildi. Taurodontizm gözlenmedi.Sonuç Kazak popülasyonunda mandibular birinci küçük azı dişleri belirgin anatomik varyasyonlar göstermektedir. C-şekilli kanallar, iki köklü formlar, Tip V kanal konfigürasyonları ve radiküler olukların varlığı, endodontik tedavi öncesinde ayrıntılı radyografik değerlendirme ve bireyselleştirilmiş tedavi planlamasının önemini vurgulamaktadır.
