The effect of using a total-etch adhesive in combination resin-based root canal fillings on the apical leakage

Rezin esasl kök kanal dolgular ile birlikte total-etch adeziv kullanmnn apikal szntya etkisi

Özet

Amaç: Bu çalmann amac total-etch adeziv uygulanm ve uygulanmam kök kanallarnn rezin esasl patlarla doldurulduktan sonra apikal szntlarnn deerlendirilmesidir. Gereç ve Yöntemler: 40 adet tek kanall insan dii sement- mine birleimi hizasndan kronlar kesilerek ayrld. Kanal preparasyonlar için standart 04 koniklikte Ni-Ti döner eeler (Profile, Dentsply- Maillefer, Switzerland) kullanld. Hazrlanan kökler dört gruba ayrld. Grup1: AH Plus ve gutta perka ile dolduruldu. Grup 2: EndoREZ ve gutta perka ile dolduruldu. Grup 3: Total-etch adeziv (Bond it, Pentron CT, USA) uygulandktan sonra AH Plus ve gutta perka ile dolduruldu. Grup 4: Bond it adeziv uygulanp EndoREZ ve gutta perka ile dolduruldu. Örnekler 37 C° ve % 100 nemli ortamda bekletildikten sonra sv filtrasyon yöntemiyle szntlar ölçüldü. Tek yönlü ANOVA ve TUKEY testleri ile istatistiksel deerlendirmeler yapld. Dentin-kanal dolgusu adaptasyonu ise SEM ile incelendi. Bulgular: Gruplar arasnda istatistiksel fark olduu tespit edildi (p<0.05). AH Plus grubu, AH Plus+Bond-it ve EndoREZ+Bond-it gruplarna göre daha fazla sznt gösterdi (p<0.05). Ek olarak, AH Plus+Bond it grubunun EndoREZ grubundan istatistiksel olarak anlaml derecede farkl olduu belirlendi (p<0.05). Sonuç: Bu çalma koullarnda total etch adeziv kullanmnn sznty azaltt ancak tam bir szdrmazlk oluturamad görüldü.

Abstract

Purpose: This study was performed to evaluate the apical leakage of the canals obturated with resin based sealers with and without a total-etch adhesive. Materials and Methods: The crowns of forty extracted human teeth with single canals were removed at the CEJ allowing access to the canals. The canals were instrumented with 04 tapered Profiles and specimens divided into four groups. Grup1: AH Plus and gutta percha was used for obturation Grup 2: EndoREZ and gutta percha was used for obturation. Grup 3: Bond it was applied to canal walls, AH Plus and gutta percha was used for obturation. Grup 4: Bond it was applied to canal walls, EndoREZ and gutta percha was used for obturation. After storing the samples in 100% humidity at 37°C for one week, apical leakage was measured using a fluid filtration testing method. Dentin-Filling adaptation was analysed with SEM. One way ANOVA and TUKEY tests were used for the statistical analysis. Results: Statistically a significant difference was found among the mean leakage values of the groups. AH Plus group demonstrated much more leakage than AH Plus+Bond-it and EndoREZ+Bondit groups (p<0.05). Additionally, AH Plus+Bond-it group was statistically different from EndoREZ group (p<0.05). Conclusion: In the conditions of this study, using a total-etch adhesive in root canal obturation with resin based sealers reduced apical microleakage but did not completely prevent leakage.
