ABSTRACT
Objective: This study aims to evaluate the prevalence of impacted 3rd molar, angulation status, the level of eruption, relationship with the occlusal plane of the 3rd molar teeth, and the rate of pathology in their own and the adjacent tooth of Turkish adult individuals who applied to Akdeniz University Faculty of Dentistry via panoramic radiographic images. Material and Methods: 700 patients were examined for this retrospective study. In addition to the localization, eruption, angulation, and occlusal level of the 3rd molars, the accompanying pathologies and the pathologies in the adjacent 2nd molars were recorded and retromolar spaces were measured. p-value of <0.05 was considered statistically significant. Results: The rate of impaction in a total of 2800 3rd molars was 29%. Impacted 3rd molars were found at a higher rate (54.4%) in the mandible. It was determined that the 3rd molar teeth were mostly in the vertical position (77.8%) and 63.1% of them were at level A. 49.9% of mandibular third molar teeth were in class I. Conclusion: Impacted 3rd molar teeth prevalence was 29 %. The most common angulation status was vertical. According to the level of impaction, it was determined that the occlusal planes of the 3rd molars and the 2nd molars were at the same level most frequently. The location of the 3rd molar completely in front of the anterior ramus was the most common position. The most common pathology in the 3rd molars was caries, and no pathology was found in the 2nd molars except caries.

ÖZET
Amaç: Bu çalışmada, Akdeniz Üniversitesi Diş Hekimliği Fakültesine başvuran Türk erişkin bireylerin gömülü 3. büyük azı dişlerinin prevalansı, açılanma durumu, sürme düzeyi, 3. büyük azı dişlerinin okluzal düzlemi ile ilişkisi ve kendi ve komşu dişteki patoloji oranlarının panoramik radyografik görüntüler ile değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Bu retrospektif çalışma için 700 hasta incelendi. Üçüncü büyük azı dişlerinin lokalizasyonu, sürme durumu, açılanma durumu ve okluzal düzeyine ek olarak eşlik eden patolojiler, komşuluğundaki 2. büyük azı dişlerinde görülen patolojiler kaydedilerek retromolar boşluklar ölçüldü. İstatistiksel anlamlılığın p<0,05 olduğu varsayıldı. Bulgular: Toplam 2800 3. molar dişte gömülü olma oranı %29 idi. Gömülü 3. molar dişler mandibulada daha yüksek oranda (%54,4) bulundu. Üçüncü molar dişlerinin en çok dikey pozisyonda olduğu (%77,8) ve %63,1'inin A düzeyinde olduğu tespit edildi. Mandibular 3. molar dişlerin %49,9'u sınıf I'deydi. Sonuç: Gömülü 3. molar diş prevalansı %29 idi. Üçüncü molarlarda en yaygın görülen açılanma durumu dikey açılanma idi. İmpaksiyon seviyesine göre en sık 3. molarların ve 2. molarların okluzal düzlemlerinin aynı seviyede olduğu tespit edildi. Mandibular 3. molar dişlerin anterior ramusun tamamen önünde yer alması en sık görülen pozisyondu. Üçüncü molarlarda en sık görülen patoloji çürüktü ve 2. molarlarda çürük dışında patolojiye rastlanılmadı.
