Özet:

 Aim: The aim of this study is to investigate changes in the gonial angles of impacted lower third molars and associated parameters in individuals with impacted lower third molars aged twenty years and below. Material and Methods: A retrospective study included 963 patients with impacted third molars. Impaction classification was done according to Pell-Gregory criteria. The teeth were divided into eight main groups based on their relationship with the ramus and second molar 1, 2, 3 and the depth within the bone A, B, C. Teeth classified as erupted in 1A were excluded from the study. Gonial angle, mesiodistal distance MDM, retromolar eruption distance RED, retromolar eruption ratio RER, A angle between the Gonion-symphysis plane and the long axis of the third molar, and B angle between the Gonion-symphysis plane and the long axis of the second molar were evaluated. Panoramic radiographs were analyzed using specialized software to measure angles and distances. The angles and measurements were compared among impacted groups and genders. Statistical analyses including Pearson correlation and ANOVA tests were used to assess relationships between measurements and impact parameters. A significance level of p0.05 was considered statistically significant. Results: In females, the A was found to be significantly larger than in males p0.05. In males, however, RSM and RSO were found to be significantly larger than in females p0.05. There was no significant variation in gonial angle among the impaction groups. A angle was the narrowest in group 3B and the largest in group 2A. Conclusion: While gonial angle are not a definitive indicator of impacted third molars, the study emphasizes the importance of A and RED in predicting impaction.

 Amaç: Bu çalışmanın amacı, alt yirmi yaş dişlerine sahip bireylerde gömülülük gösteren dişlerin gonial açıları ve bu durumla ilişkili parametrelerdeki değişiklikleri araştırmaktır. Gereç ve Yöntemler: Retrospektif olarak yapılan araştırmada gömülü üçüncü molar dişleri olan 963 hasta çalışmaya dahil edildi. Gömülülük sınıflaması Pell-Gregory kriterlerine göre yapıldı. Dişin ramus ve 2. molar ile olan ilişkisine göre 1,2,3 ve dişin kemik içerisindeki derinliğine A, B, C göre sekiz ana gruba ayrılmıştır.1A sınıflamasındaki dişler sürmüş kabul edilerek çalışma dışı bırakılmıştır. Gonial açı, meziodistal mesafe MDM, retromolar sürme mesafesi RSM, retromolar sürme oranı RSO, AGonion-simfiz noktaları arasına çizilen düzlem ile 3. molar diş uzun ekseni arasındaki açı ve BGonion-simfiz arasına çizilen düzlem ile 2. molar dişin uzun ekseni arasındaki açı değişkenleri değerlendirilmiştir. Panoramik radyografiler özel bir yazılım kullanılarak açılar ve mesafeler ölçülerek analiz edildi. Açı ve ölçümler gömülü grupları ve cinsiyetler arasında karşılaştırıldı. Ölçümler ve etki parametreleri arasındaki ilişkileri değerlendirmek için Pearson korelasyonu ve ANOVA testlerini içeren istatistiksel analizler kullanıldı. İstatistiksel anlamlılık değeri p0,05 olarak kabul edilmiştir. Bulgular: Kadınlarda A açısı, erkeklere göre anlamlı olarak daha büyük bulunmuştur p0.05. Erkeklerde ise RSM ve RSO, kadınlara göre anlamlı olarak daha büyük bulunmuştur p0.05. Gömülülük grupları arasında gonial açı bakımından anlamlı değişim bulunamamıştır. A açısı 3B grubunda en dar açı iken 2A grubunda en büyük açıya sahiptir. Sonuç: Gonial açı üçüncü molar dişlerin gömülü kalmasının kesin bir göstergesi olmasa da, çalışma A ve RSMnin gömülü kalmayı öngörmedeki öneminin altını çizmektedir.
