The Quantitative Method for Following Radiologic Healing in Endodontic Retreatment; 1-Year Follow-up Study

Abstract

Objectives: This study aimed to quantitatively evaluate the changes in the internal bone structure at the periapical bone regions after retreatment in endodontics using fractal analysis method on periapical radiographs. Materials and Methods: 29 single-rooted, asymptomatic, single-visit retreatment teeth with apical lesion were included in the study. All teeth included in the study were selected from the maxilla anterior region. Periapical radiograph (T0) was taken for baseline diagnosis at the start of retreatment. Second periapical follow-up radiograph (T1) of the patients was taken at the end of 1 year. The first evaluation phase of the 1-year results of endodontic retreatment is based on the periapical index (PAI). Fractal dimension (FD) was calculated by box-counting method. The paired-sample t-test was used to compare T0 and T1 FDs. The independent samples t-test was employed to compare FD changes between the sexes. The significance level was set to 0.05. Results: PAI scores were found to be statistically significantly decreased in T1 radiographs compared to T0 (p<0.001). The mean FD value increased statistically significantly in T1 radiographs compared to T0 radiographs (p<0.001). No significant difference was found in the T0 and T1 radiographs of FDs in gender comparison (p>0.05). Conclusion: At the end of the 1-year follow-up, FD increased in the periapical lesion area, which is interpreted as the healing of the lesions. Fractal analysis is recommended as a method that will benefit clinicians in the follow-up of retreatment recovery.

Öz

Amaç: Bu çalışmada endodontide retreatment sonrası periapikal kemik bölgelerinde internal kemik yapısında meydana gelen değişikliklerin fraktal analiz yöntemi kullanılarak periapikal radyografiler üzerinde kantitatif olarak değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmaya apikal lezyonu olan 29 adet tek köklü, asemptomatik, tek seans retreatment yapılan dişler dahil edildi. Çalışmaya dahil edilen tüm dişler maksilla anterior bölgesinden seçilmiştir. Retreatment başlangıcında temel tanı için periapikal radyografi (T0) çekildi. Hastaların 1. yıl sonunda ikinci periapikal kontrol grafileri (T1) çekildi. Endodontik retreatmentın 1 yıllık sonuçlarının ilk değerlendirme aşaması periapikal indekse (PAI) dayalıdır. Fraktal boyut (FB), kutu sayma yöntemiyle hesaplandı. The paired-sample t-testi T0 ve T1 FB'leri karşılaştırmak için kullanıldı. Cinsiyetler arasındaki FD değişikliklerini karşılaştırmak için bağımsız örneklem t testi kullanıldı. Anlamlılık düzeyi 0.05 olarak kabul edildi. Bulgular: PAI skorları T1 grafilerde T0'a göre istatistiksel olarak anlamlı derecede düşük bulundu (p<0.001). Ortalama FB değeri T1 grafilerde T0 grafilere göre istatistiksel olarak anlamlı artış gösterdi (p<0.001). FB'lerin T0 ve T1 grafilerinde cinsiyet karşılaştırmasında anlamlı fark bulunmadı (p>0,05). Sonuç: 1 yıllık takibin sonunda periapikal lezyon bölgesinde FB artışı lezyonların iyileşmesi olarak yorumlanmaktadır. Fraktal analiz, retreatment sonrası iyileşmenin takibinde klinisyenlere fayda sağlayacak bir yöntem olarak önerilmektedir.
