Qmix’in Farklı Uygulama Süreleri Sonrası Kök Kanal Dentini Üzerine Etkisi: SEM ve EDS Analizi

Amaç: İrrigasyon solüsyonları ve şelasyon ajanları dentinin kimyasal kompozisyonunu değiştirebilmektedir. Bu çalışmanın amacı, farklı uygulama süreleri sonrası QMix’in smear tabakasını uzaklaştırma etkinliği ve kök kanal dentininde Ca/P oranına etkisini değerlendirmektir.Gereç ve Yöntem: Atmış adet çekilmiş diş şekillendirildi ve solüsyonun uyguşama sürelerine göre 5 gruba ayrıldı n=12 . Grup 1’de irrigasyon uygulanmadı kontrol . Diğer gruplar sırasıyla şu şekilde tanımlandı; QMix solüsyonu 1, 3, 5 ve 10 dakika süre ile uygulandı. Smear tabakası skorları, erozyon skorları ve Ca/P oranı SEM ve EDS ile değerlendirildi. bulgular: Apikal ve orta bölgede smear tabakası skorları 10 dakika grubunda 1 dakika grubuna göre anlamlı derecede düşük çıktı P0.05 .Sonuç: QMix dentin tübüllerinde herhangi bir erozyona yol açmadan ve Ca/P oranınada değişikliğe neden olmadan 10 dakika içerisinde smear tabakayı uzaklaştırabilmektedir

The Efficacy of QMix on the Root Canal Dentin After Different Exposure Time Periods: A SEM and an EDS Analysis

Aim: The irrigation solutions and chelating agents are able to change the chemical composition of dentin. This study aimed to evaluate the efficacy of QMix on the removal of smear layer and the Ca/P ratio of root canal dentine after different exposure time periods.Material and Method: Sixty extracted teeth were prepared and divided into 5 groups according to the application time of the solution n=12 . In group 1, no irrigation was performed control . The other groups were defined as follows consecutively; QMix solution were used for 1, 3, 5 and 10 minutes. Smear layer scores, erosion scores and Ca/P ratios of each group were evaluated by SEM and EDS. Results: In apical and middle regions, smear layer scores of 10 minute group, was significantly lower than 1 minute group P0.05 . Conclusion: QMix is able to remove smear layer effectively in 10 minutes without causing any erosion in dentinal tubules or alteration in the Ca/P ratio
