Objective: The aim of this study was to evaluate the effect of 9% etidronic acid (HEBP) and 17% ethylenediamine tetraacetic acid (EDTA) on the surface roughness of Biodentine.

Materials and Method: Biodentine (Septodont) was mixed according to the manufacturer’s instructions. Briefly, five drops of liquid were added into the capsule containing the powder. Then the capsule was placed in a triturator for 30 sec. The prepared mixture was placed into a mold (diameter: 5 mm, depth: 3 mm). The Biodentine surfaces were polished with silicon carbide abrasive papers. The surface roughness of 30 samples was measured at baseline using a portable surface roughness tester. For this purpose, a 5 mN force was applied onto three different locations of the samples with a speed of 0.8 mm/sec. The samples were divided into two groups according to the irrigation solution (n=15); first group was treated with 9% HEBP, and the second group was treated with 17% EDTA. The surface roughness of the samples was measured again after 1 and 2 min of irrigant application. Data were statistically analyzed using one-way ANOVA and independent sample t-test.

Results: For HEBP, no significant difference was found between the surface roughness values at 0., 1., and 2 min (p=0.107; ANOVA). For EDTA, the surface roughness value at 1 min was significantly greater than the baseline value (p<0.001; t-test). The surface roughness changes at the two time periods were significantly different between the EDTA and HEBP groups (p=0.003 for 0-1 min passage, p=0.021 for 1-2 min passage).

Conclusion: The use of 17% EDTA may result in deterioration of Biodentine’s surface during perforation repair and root canal treatment.

Öz

Amaç: Bu çalışmanın amacı %9 etidronik asit (HEBP) ve %17 etilendiamin tetraasetik asitin (EDTA) Biodentine yüzey pürüzlülüğü üzerine etkilerini değerlendirmektir.

Gereç ve Yöntem: Biodentine (Septodont) üretici firma talimatları doğrultusunda karıştırıldı. Kısaca, tek doz toz içeren kapsül içerisine 5 damla likit eklendi. Daha sonra kapsül, karıştırıcıda 30 sn karıştırıldı. Hazırlanan karışım 5 mm çapında, 3 mm derinliğinde çelik kalıp içine yerleştirildi. Biodentine yüzeyleri silikon karbid zımpara kağıtlarla parlatıldı. Otuz örneğin başlangıç yüzey pürüzlülüğü, portatif yüzey pürüzlük cihazı (Perthometer M2) kullanılarak ölçüldü. Bu amaçla, örneklerin üç farklı bölgesine 0.8 mm/sn hızla 5 mN kuvvet uygulandı. Örnekler kullanılan irrigasyon solüsyonuna göre iki gruba ayrıldı (n=15). Birinci gruptaki örneklere %9 HEBP, ikinci gruptaki örneklere %17 EDTA uygulandı. Örneklerin yüzey pürüzlülüğü irrigasyon uygulamasından sonra 1. ve 2. dakikalarda ölçüldü. Bütün zaman dilimlerinde, her bir örneğin üzerinde farklı bölgelerden 3 ölçüm yapıldı. Veri tek yönlü ANOVA ve bağımsız örneklem t-testi ile istatistiksel olarak analiz edildi.

Bulgular: HEBP grubunda 0., 1. ve 2. dakika değerleri arasında fark yoktu (p=0.107; ANOVA). Biodentine yüzey pürüzlülüğü değerleri,EDTA kullanımında, 1. dakika sonunda başlangıç değerlerine göre istatistiksel olarak anlamlı şekilde arttı (p<0.001; t-testi). İki zaman dilimindeki yüzey pürüzlülük değişimleri EDTA ve HEBP grupları arasında istatistiksel olarak farklıydı (0-1 dakika geçişi için p=0.003, 1-2 dakika geçişi için p=0.021).

Sonuç: Perforasyon tedavisi ve kök kanal tedavisi sırasında %17 EDTA kullanımı Biodentine yüzeyinde bozulmalara neden olabilmektedir.
