Objective: The aim of this study is to determine the incidence of ectopic eruption in permanent first molar teeth retrospectively with 2 different classification methods, based on radiographic findings, during the transition from primary dentition to permanent dentition. Material and Methods: This study was conducted with children aged between 6-12 years admitted to pediatric dentistry department. The orthopantomographic radiographs of 2,516 patients were examined. The patients' age and gender, teeth with ectopic eruption and the jaw were recorded. In the classification of ectopic eruption, Young and Barberia-Leache et al.'s classification was used. Data were analyzed with IBM SPSS V23. Differences between teeth were examined with Cochran's Q test. The correlation between Barberia- Leache classification and Young's classification was evaluated with the chi-square test. Significance level was taken as p<0.05. Results: A total of 2,516 patients were included in the study and ectopic eruption was seen in a total of 70 teeth in 47 (23 girls, 24 boys) patients. The prevalence of ectopic eruption was found to be 1.9%. Ectopic eruption of the permanent first molar tooth was seen more in the upper jaw than in the lower jaw. According to Young's classification, the prevalence of permanent first molar eruption in reversible type is higher, while the prevalence of Grade I permanent first molar ectopic eruption is higher according to Barberia-Leache et al.'s classification. Conclusion: Even in cases of ectopic eruption in permanent first molars that are considered severe according to Barberia-Leache et al. classification and Young's classification, spontaneous recovery can be observed with long-term follow-up.

Giriş: Bu çalışmada amacımız; süt dişlenme döneminden daimi dişlenme dönemine geçişte, daimi 1. molar dişlerde ektopik erüpsiyon görülme sıklığını radyografik bulgulara dayanarak, 2 farklı sınıflandırma yöntemi ile retrospektif olarak belirlemektir. Gereç ve Yöntemler: Bu çalışma, çocuk diş hekimliği ana bilim dalına başvuran 6-12 yaş arası çocuklarla yapıldı. İki bin beş yüz on altı hastanın ortopantomografik radyografileri incelendi. Hastaların yaş ve cinsiyeti, ektopik erüpsyon görülen dişleri ve çenesi kaydedildi. Ektopik erüpsiyon sınıflandırmasında Young ve Barberia-Leache ile ark.nın sınıflandırması kullanıldı. Veriler IBM SPSS V23 ile analiz edildi. Dişler arasındaki farklılıklar Cochran Q testi ile incelendi. Barberia-Leache sınıflaması ile Young sınıflaması arasındaki korelasyon ki-kare testi ile değerlendirildi. Anlamlılık düzeyi p<0,05 olarak alındı. Bulgular: İki bin beş yüz on hasta çalışmaya dâhil edildi ve 47 (23 kız, 24 erkek) hastada toplam 70 dişte ektopik erüpsiyon görüldü. Ektopik erüpsiyon prevalansı %1,9 olarak bulundu. Daimi 1. molar dişin ektopik erüpsiyonu alt çeneye göre üst çenede daha fazla görüldü. Young sınıflamasına göre reversible tipte ektopik erüpsiyon görülen daimi 1. molar prevalansı daha fazlayken, Barberia-Leache ve ark.nın sınıflamasına göre Derece I daimi 1. molar ektopik erüpsiyon prevalansı daha fazladır. Sonuç: Çalışmamızda, Barberia-Leache sınıflandırmasına göre Derece I'den III'e doğru gidildikçe reversible olma eğilimi artmıştır. Daimi 1. Molar dişlerde Barberia-Leache ve ark.nın sınıflamasına ve Young sınıfladırmasına göre şiddetli kabul edilen ektopik erüpsiyon vakalarında dahi uzun dönem takiple kendiliğinden düzelme görülebilir.
