Süt Dişlerinde Farklı EDTA Konsantrasyonlarının Smear Tabakasını Uzaklaştırma Etkinliği: Bir SEM Çalışması

Öz

Amaç: Bu çalışma farklı konsantrasyonlardaki etilendiamin tetraasetik asitin (EDTA), süt dişlerinde smear tabakasının uzaklaştırılmasına olan etkilerini tarama elektron mikroskopu (TEM) ile değerlendirmeyi amaçlamaktadır. Gereç ve Yöntemler: Bu çalışma 28 adet çekilmiş üst süt kesici diş ile gerçekleştirilmiş ve bu dişler %5, %10, %17 EDTA ve %1 sodyum hipoklorit (NaOCl) olacak şekilde dört ana gruba (n=7) atanmıştır. Kök kanal irrigasyon prosedürlerinin ardından, kök kanal yüzeyleri (koronal, orta ve apikal) SEM ile taranmış ve smear tabakası uzaklaştırma skorları kaydedilmiş ve karşılaştırılmıştır. Sonuçlar Kruskal–Wallis, Friedman ve Dunn testleri kullanılarak analiz edilmiştir. Bulgular: Tüm kök bölümlerinde, EDTA gruplarının smear tabakasını NaOCl’den daha efektif uzaklaştırmasına rağmen, sadece orta üçlüde %17 EDTA ile %1 NaOCl arasında istatistiksel anlamlı fark gözlenmiştir (p<0.05). Smear tabakası, birçok grupta (%10 EDTA, %17 EDTA ve %1 NaOCl) koronalde apikale göre daha efektif uzaklaştırılmıştır (p<0.05). Eroziv defektler en çok %17 EDTA, daha az olarak da %10 EDTA grubunda görülmüş ve bu bulgulara %5 EDTA ve %1 NaOCl gruplarında saptanmamıştır. Sonuç: Smear tabakası uzaklaştırılmasında, NaOCl ve yüksek konsantrasyondaki EDTA grupları ile benzer etkinlik sunması, düşük eroziv potansiyeli ve periapikal güvenlik için düşük konsantrasyonu nedeniyle süt dişi kanal tedavilerinde irrigasyon solüsyonu olarak %5 EDTA kullanımını önermek mümkündür.

The Smear Layer Removal Efficiency of Different Concentrations of EDTA in primary teeth: A SEM Study

Abstract

Objectives: The present study aims to evaluate the effects of different concentrations of ethylenediamine tetraacetic acid (EDTA) on smear layer removal in primary teeth by using scanning electron microscopy (SEM). Materials and Methods: The present study was performed with 28 extracted upper primary incisors assigned into four main groups (n=7) as 5%, 10% and 17% EDTA, and 1% sodium hypochlorite (NaOCl). The root canal surfaces (coronal, middle and apical) were scanned by SEM and scores of smear layer removal were recorded and compared after the root canal irrigation procedures. The results were analyzed using Kruskal–Wallis, Friedman and Dunn tests. Results: In all the root portions, although EDTA groups removed the smear layer more effectively than NaOCl, a statistically significant difference was observed between 17% EDTA and 1% NaOCl only in middle third (p <0.05). Also, smear layer was removed more effectively in coronal than apical in most of the groups (10% EDTA, 17% EDTA and 1% NaOCl) (p <0.05). Erosive defects were mostly seen in 17% EDTA and less than 10% EDTA group. These findings were not detected in 5% EDTA and 1% NaOCl group. Conclusions: It is possible to recommend the use of 5% EDTA irrigation solution in root canal treatment of primary teeth due to its similar smear layer removal efficacy with NaOCl and high concentration EDTA groups, low erosive potential and low concentration for periapical safety.
