Evaluation of Different Irrigation Solutions on the Bond Strength of Calcium Silicate-Based Materials

Abstract

Objective: This study aimed to investigate the effect of using 17% glycolic acid and 17% EDTA as final irrigation solutions on the bond strength of calcium silicate-based root canal sealers (CeraSeal and MTA Bio Seal). Materials and Methods: A total of 68 extracted human mandibular premolars were used in this study. The coronal portions of the teeth were removed to obtain a standardized working length of 13 mm. Following chemomechanical preparation of the root canals, the teeth were randomly divided into four groups based on the final irrigation solution and sealer used: Group 1: 17% EDTA and MTA Bio Seal sealer, Group 2: 17% EDTA and CeraSeal sealer, Group 3: 17% glycolic acid and MTA Bio Seal sealer, Group 4: 17% glycolic acid and CeraSeal sealer. Thin slices were obtained from each sample at 4 mm and 9 mm from the apical constriction. Push-out bond strength testing was performed to assess the adhesion of the root canal filling material. The bond strength data of all groups were analyzed using the Kruskal-Wallis test. The Mann-Whitney U test was used to compare differences between the two sections (4 mm and 9 mm) obtained from the same sample. Statistical significance was set at p<0.05. Results: Comparative analysis revealed that in both sections, the bond strength values in Groups 3 and 4 (17% glycolic acid) were significantly higher than those in Groups 1 and 2 (17% EDTA) (p<0.05). Additionally, in all groups, bond strength values at the 9 mm level were significantly higher than those at the 4 mm level (p<0.05). Conclusions: The use of 17% glycolic acid as a final irrigation solution resulted in higher bond strength values of calcium silicate-based sealers compared to 17% EDTA.

Farklı İrrigasyon Solüsyonu Kullanımının Kalsiyum Silikat İçerikli Materyallerin Bağlanma Dayanımına Etkisinin Değerlendirilmesi

Abstract

Amaç: Bu çalışmada, kök kanallarının final irrigasyonunda %17’lik glikolik asit ve %17’lik EDTA kullanımının kalsiyum silikat esaslı kanal dolgu patları (CeraSeal ve MTA Bio Seal) üzerindeki bağlanma dayanımına etkisi araştırılmıştır. Gereç ve Yöntemler: Çalışmada, toplam 68 adet insan alt premolar dişi kullanılmıştır. Dişlerin koronal kısımları, çalışma uzunlukları 13 mm olacak şekilde uzaklaştırılmıştır. Kök kanallarının kemomekanik preparasyonunun ardından dişler, farklı final irrigasyon prosedürleri ve kanal dolgu patları uygulanmak üzere rastgele dört gruba ayrılmıştır: Grup 1: %17’lik EDTA ve MTA Bio Seal patı, Grup 2: %17’lik EDTA ve CeraSeal patı, Grup 3: %17’lik glikolik asit ve MTA Bio Seal patı, Grup 4: %17’lik glikolik asit ve CeraSeal patı. Örneklerden, apikal konstriksiyondan itibaren 4. ve 9. mm seviyelerinden hassas kesitler alınmıştır. Push-out testi ile kesitlerdeki kök kanal dolgusunun bağlanma dayanımı değerleri hesaplanmıştır. Tüm gruplardaki bağlanma dayanımı verileri Kruskal-Wallis testi ile analiz edilmiştir. Aynı örnekten alınan iki kesit (4. mm ve 9. mm) arasındaki farkın belirlenmesi için ise Mann-Whitney U testi kullanılmıştır. İstatistiksel anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. Bulgular: Gruplar arasındaki karşılaştırmada, her iki kesitte de %17’lik glikolik asit kullanılan 3. ve 4. gruplarda bağlanma dayanımı değerleri, %17’lik EDTA kullanılan 1. ve 2. gruplara kıyasla istatistiksel olarak anlamlı derecede yüksek bulunmuştur (p<0,05). Ayrıca, tüm gruplarda 9. mm seviyesinden alınan kesitlerdeki bağlanma dayanımı, 4. mm seviyesinden alınan kesitlere kıyasla istatistiksel olarak anlamlı derecede yüksek bulunmuştur (p<0,05). Sonuç: %17’lik glikolik asitin kullanımı, %17’lik EDTA ile karşılaştırıldığında kalsiyum silikat içerikli patların bağlanma dayanımını arttırmıştır.
