ÖZET
 Amaç: Bu çalışmanın amacı, 2 farklı uzmanlık alanında eğitim gören diş hekimlerinin, 3. molar diş pozisyonlarının sınıflandırılması hakkındaki bilgi düzeylerini değerlendirmektir. Gereç ve Yöntemler: Bu çalışmaya 12 ağız, diş ve çene radyolojisi (Grup 1) ile 18 ağız, diş ve cerrahisi uzmanlık alanından (Grup 2) olmak üzere toplam 30 gönüllü diş hekimi dâhil edildi. Katılımcılar, 46 soruluk anket formunu cevaplandırdı. Anket formunun 1. bölümünde bilgi soruları, 2. Bölümünde görsel sorular yer aldı. Görsel sorularda, 3. molar dişlerin Pell ve Gregory ile Winter sınıflamasına göre ait oldukları pozisyonlar soruldu. İlk aşamada görsel sorularda, sınıflamalara ait gerekli düzlem çizimleri/açı ölçümleri yoktu. İkinci aşamada aynı görüntüler üzerinde gerekli düzlem çizimleri/açı ölçümleri yapılarak karışık bir sıra ile tekrar soruldu. Anket sorularına verilen doğru cevaplar Pearson ki-kare testi ve eşleştirilmiş t-testi ile istatistiksel olarak analiz edildi. Bulgular: Alt 3. molar diş pozisyonlarının, gerekli düzlem çizimleri yapılmadan önceki ve yapıldıktan sonraki verilen doğru cevap sayısında Pell ve Gregory sınıflamasına ait ramus ilişkisine göre 2 grup arasında istatistiksel olarak anlamlı bir fark bulundu (p<0,05). Sonuç: Bu sınıflamalar en çok bilinen ve kullanılan sınıflamalar olmakla birlikte, gerekli düzlemler çizimleri ve açı ölçümleri yapılarak 3. molar diş pozisyonlarına karar verilmelidir.

ABSTRACT
 Objective: The aim of this study to evaluate the knowledge levels of dentists trained in two different specialties about the classification of third molar tooth positions. Material and Methods: Totally 30 volunteer dentists, including 12 oral and maxillofacial radiologists (Group 1), 18 oral and maxillofacial surgeon (Group 2), were included in the study. The participants were answered the 46-question survey form. Information questions were included in the first part, and visual questions in the second part of the survey form. In the visual questions, the positions of third molar teeth belonging to Pell and Gregory and Winter classification were asked. In the first stage, visual questions were asked without drawing the planes/measuring angle valid in these classifications. In the second stage, the same images were asked again in a mixed order by making the necessary plane drawings/angle measurements. The correct answers were statistically analyzed by Pearson chi-square test and paired t-test. Results: A statistically significant difference was found between two groups in the number of correct answers given before and after the required plane drawings of the lower third molar tooth positions, according to the ramus relationship of the Pell and Gregory classification (p<0.05). Conclusion: Although these classifications are the most known and used classifications, third molar tooth positions should be decided by making necessary plane drawings and angle measurements.
