Publication: sodyum hipoklorit, EDTA, propolis, borik asit ve sitrik asit yıkama solüsyonlarının kök kanal patlarındaki bağlanma dayanımları üzerine etkisinin incelenmesi
Abstract
Amaç: Bu çalışmanın amacı; farklı kök kanal yıkama solüsyonlarının AH Plus ve Bioserra kanal patlarının kök dentinine bağlanma dayanımına olan etkisini incelemektir. Gereç ve Yöntem: Bu çalışmada 100 adet tek köklü diş kullanılmıştır. Kök kanalları Protaper Next X3 (Dentsply Maillefer, Ballaigues, İsviçre) döner alet eğesi ile şekillendirildi. Dişler 2 gruba ayrıldı (AH Plus ve Bioserra) ve her grup, irrigasyon solüsyonuna göre 5 alt gruba ayrıldı (n=10). Uygulanan irrigasyon solüsyonları şunlardır: %5.25 sodyum hipoklorit (NaOCl), %17 etilendiamin tetraasetik asit (EDTA), %10 sitrik asit, %10 borik asit, %10 propolis. Her bir dişin kökünün orta hizasından 2 mm kalınlığında horizontal kesitler alındı ve kanal dolgusuna bağlantıda kopma meydana gelene kadar test cihazı (Shimadzu, Japonya) ile dikey yönde basma kuvveti uygulandı. Numuneler binoküler mikroskopla incelendi ve kanal patlarının bağlanma dayanım değerleri (POBS) hesaplandı. İstatistiksel analizler Kruskal-Wallis H ve Mann-Whitney U testleri ile yapıldı. Bulgular: Kullanılan kanal patından bağımsız olarak yıkama solüsyonuna göre gruplar karşılaştırıldığında; NaOCl gruplarında bağlanma dayanım değeri ortalamaları diğer gruplara göre istatistiksel olarak anlamlı derecede yüksek bulunmuştur (p<0,05). Bioserra kullanılan gruplar arasında NaOCl grubu, diğer gruplardan istatistiksel olarak anlamlı derecede daha yüksek bulunmuştur (p<0,05). Kanal patına göre POBS ortalamaları karşılaştırıldığında; AH Plus kullanılan grubun POBS ortalaması Bioserra kullanılan gruptan anlamlı derecede yüksektir (p<0,05). EDTA ve sitrik asit gruplarında AH Plus kullanılan örneklerin POBS ortalaması, Bioserra kullanılan örneklere göre anlamlı derecede yüksek bulunmuştur (p<0,05). Sonuç: Bağlanma dayanım gücü; “kullanılan kök kanal patı” faktöründen ve “kanal patı/ yıkama solüsyonu etkileşimi”nden önemli ölçüde etkilenmektedir. Kanal irrigasyon solüsyonu olarak %17’lik EDTA veya %10’luk sitrik asit kullanılacak ise ardından kök kanal dolumunda AH Plus kanal dolum patını tercih etmek, Bioserra kanal patını tercihe kıyasla bağlanma dayanım değerlerini artıran bir faktör olacaktır.
Objective: The aim of this study is to investigate the effect of different root canal irrigation solutions on the bonding strength of AH Plus and Bioserra root canal sealers on root dentin. Materials and Methods: In this study, 100 single root teeth were used. The root canals of these teeth were instrumented with a Protaper Next X3 (Dentsply Maillefer, Ballaigues, Switzerland) rotary file. The teeth were divided into 2 groups according to the root canal filling material (AH Plus and Bioserra) and each group was divided into 5 subgroups (n=10). The irrigation solutions applied are as follows: 5.25% NaOCl, 17% EDTA, 10% citric acid, 10% boric acid, 10% propolis. Horizontal sections with a thickness of 2 mm were taken from the middle level of the each tooth’s root and a vertical compression force was applied to the canal fillings by a testing machine (Shimadzu, Japan) until a failure occurred in the connection. After the compression test, both the samples were examined with the binocular microscope (Leica, Germany) and the POBS values of the root canal sealers were calculated. Statistical analyses were performed using Kruskal-Wallis H and Mann-Whitney U tests. Results: When the groups were compared according to the irrigation solution regardless of the root canal sealer used, the average bonding strength values were found to be statistically significantly higher in NaOCl groups compared to other solution groups (p<0.05). Among the Bioserra groups, NaOCl group had statistically significantly higher average POBS values than other irrigation solution groups (p<0.05). POBS average of the AH Plus group was significantly higher than the Bioserra group (p<0.05). POBS average of the samples using AH Plus in the 17% EDTA and 10% citric acid groups was found to be significantly higher compared to the average of the Bioserra samples (p<0.05). Conclusion: The bonding strength is significantly affected by the root canal sealer used factor and the sealer/ irrigation solution interaction. If 17% EDTA or 10% citric acid is to be used as the root canal irrigation solution, then choosing AH Plus sealer for root canal filling will be a factor that increases the bond strength values compared to choosing Bioserra sealer.
