The Effect Of Usıng Glycolıc Acıd At Dıfferent Concentratıons On The Bond Strength Of Root Canal Fıllıng Materıals

Öz

Objective: The aim of this study was to investigate the effect of different final irrigation procedures on the bond strength of MTA Fillapex root canal sealer.

Material and Method: 98 caries-free human lower premolar teeth were used in this study. The coronal sections of the teeth were removed with a working length of 12 mm. Root canals were shaped with the ProTaper Next. Samples were randomly distributed into 7 groups and different final irrigation procedures (Group 1:EDTA, Group 2:10% glycolic acid, Group 3:17% glycolic acid, Group 4:EDTA+CHX, Group5:10% glycolic acid+CHX, Group 6:17% glycolic acid+CHX and Group 7:Distilled water) were applied. Root canals were filled with MTA Fillapex and gutta percha. Sections were taken at a distance of 4 and 9 mm from the apical constriction. The bond strength values were calculated by performing the push-out test. Data were analyzed statistically using Duncan and T tests.

Results: For both sections; the highest bond strength values were found in Group 6 and the lowest values were found in Group 7 (p<0.05). Bond strength values in both sections were: Group 6>Group 3>Group 5≥Group 2>Group 4≥Group 1>Group 7. Bond strength values of root canal filling in sections taken from the 9th mm in all groups were found to be significantly higher than 4th mm (p<0.05).

Conclusion: In terms of bond strength of MTA Fillapex root canal sealer; glycolic acid showed higher values than EDTA. Final irrigation with 17% glycolic acid and CHX showed the highest bond strength values.

Farklı Konsantrasyonlarda Glikolik Asit Kullanımının Kök Kanal Dolgu Materyallerinin Bağlanma Dayanımı Üzerine Etkisi

Öz

Amaç: Bu çalışmanın amacı farklı final irrigasyon prosedürlerinin MTA Fillapex kök kanal dolgu patının bağlanma dayanımı üzerine olan etkisini araştırmaktır.
Gereç ve Yöntem: Bu çalışmada 98 adet çürüksüz insan alt premolar dişi kullanıldı. Dişlerin koronal bölümleri çalışma uzunlukları 12 mm olacak şekilde uzaklaştırıldı. Kök kanalları ProTaper Next ile genişletildi. Örnekler rastgele 7 gruba dağıtıldı ve farklı final irrigasyon prosedürleri (Grup 1:EDTA, Grup 2:%10 glikolik asit, Grup 3:%17 glikolik asit, Grup 4:EDTA+CHX, Grup 5:%10 glikolik asit+CHX, Grup 6:%17 glikolik asit+CHX ve Grup 7:Distile su) uygulandı. Kök kanalları MTA Fillapex ve guta perka ile dolduruldu. Örneklerden, apikal konstriksiyondan itibaren 4 ve 9 mm mesafede olacak şekilde kesitler alındı. Push-out testi yapılarak kesitlerdeki kök kanal dolgusunun bağlanma dayanımı değerleri hesaplandı. Veriler Duncan ve T testleri kullanılarak istatistiksel olarak incelendi.
Bulgular: Gruplar arasında yapılan değerlendirmede 4. ve 9. mm’den alınan her iki kesitte de; kök kanal dolgusunun en yüksek bağlanma dayanımı değerleri Grup 6’da, en düşük bağlanma dayanımı değerleri ise grup 7’de tespit edildi (p<0,05). Her iki kesitte de bağlanma dayanımı Grup 6>Grup 3>Grup 5≥Grup 2>Grup 4≥Grup 1>Grup 7 şeklinde tespit edildi. Grup içi değerlendirmede ise; bütün gruplarda 9. mm’den alınan kesitlerdeki kök kanal dolgusunun bağlanma dayanımı değerleri, 4. mm’den daha yüksek bulundu (p<0,05).
Sonuç: MTA Fillapex kök kanal dolgu patının bağlanma dayanımı açısından; glikolik asit EDTA’dan daha yüksek değerler gösterdi. %17 glikolik asit ve CHX ile yapılan final irrigasyonu en yüksek bağlanma dayanımı değerlerini gösterdi.
