Abstract

ABSTRACT
Objective: The goal is to find out how irrigation and chelating solutions change the average surface roughness (Ra) of resin composites when root canal treatment is done on teeth with composite restorations.
Methods: A total of 40 disc-shaped composite specimens (Tetric®-N-Ceram-Bulk-Fill-IVA) were used in the study. The specimens were randomly divided into 4 groups (n=10) and Ra values were measured before treatment. Group1 (Gr1) was then immersed in 5% sodium hypochlorite (NaOCl), group2 (Gr2) in 17% ethylenediaminetetraacetic acid (EDTA), group3 (Gr3): 10% citric acid (CA), group4 (Gr4): 0.9% saline (SS) for 15 minutes. After treatment, the Ra values of the samples were measured again. Comparison of Ra values before and after treatment was performed by paired samples t-test, and one-way ANOVA analysis was used for comparison between groups.
Results: There was a statistically-significant difference between the 4 groups in terms of post-treatment Ra measurements (p<0.05). While there was no statistically-significant difference between the pre-treatment and post-treatment Ra values in NaOCl and SS (p>0.05). There is a statistically-significant difference between the pre-treatment and post-treatment Ra values in EDTA and CA (p<0.05). There is also a statistically-significant difference between NaOCl and SS and EDTA and CA in terms of post-treatment Ra values (p<0.05).
Conclusion: Among the solutions used in our study, EDTA and CA increased the Ra values on resin composites. It is recommended to polish the surface of composite restorations after the treatment to avoid problems related to the increase in roughness after the irrigation procedure.

Endodontik İrrigasyon Solüsyonları Bulk Fill Reçine Kompozitin Yüzey Pürüzlülüğünü Nasıl Etkiler?
ÖZ
Amaç: Kompozit restorasyonlu dişlere kök kanal tedavisi yapıldığında irrigasyon ve şelasyon solüsyonlarının rezin kompozitlerin ortalama yüzey pürüzlülüğünü (Ra) nasıl değiştirdiğini bulmaktır.
Yöntemler: Çalışmada toplam 40 adet disk şeklinde kompozit numune (Tetric®-N-Ceram-Bulk-Fill-IVA) kullanıldı. Örnekler rastgele 4 gruba (n=10) ayrıldı ve tedavi öncesinde Ra değerleri ölçüldü. Daha sonra; grup 1 (Gr1): %5 sodyum hipoklorit (NaOCl), grup 2 (Gr2): %17 etilendiamintetraasetik asit (EDTA), grup 3 (Gr3): %10 sitrik asit (SA) ve grup 4 (Gr4): %0,9 salin solüsyonu (SS) içine 15 dakika boyunca daldırıldı. Tedavi sonrasında örneklerin Ra değerleri tekrar ölçüldü. Tedavi öncesi ve sonrası Ra değerlerinin karşılaştırılması için bağımlı örneklem t-testi kullanılırken, gruplar arası karşılaştırma için tek yönlü ANOVA analizi kullanıldı.
Bulgular: Tedavi sonrası Ra ölçümleri açısından 4 grup arasında istatistiksel olarak anlamlı fark vardı (p<0,05). NaOCl ve SS'de tedavi öncesi ve tedavi sonrası Ra değerleri arasında istatistiksel olarak anlamlı bir fark bulunmazken (p>0,05). EDTA ve SA'da tedavi öncesi ve tedavi sonrası Ra değerleri arasında istatistiksel olarak anlamlı fark vardır (p<0,05). Ayrıca NaOCl ve SS ile EDTA ve SA arasında tedavi sonrası Ra değerleri açısından da istatistiksel olarak anlamlı farklılık bulunmuştur (p<0,05).
Sonuç: Çalışmamızda kullanılan solüsyonlardan EDTA ve SA, rezin kompozitlerde Ra değerlerini arttırmıştır. İrrigasyon işlemi sonrasında pürüzlülük artışına bağlı problemlerin yaşanmaması için kompozit restorasyonların yüzeyinin tedavi sonrasında cilalanması tavsiye edilir.
