COMPARISON OF MICROLEAKAGE OF SELF-ADHESIVE RESIN CEMENTS USED FOR FIBER POST CEMENTATION

Abstract

Aim: The aim of this study was to compare the microleakage of four self-adhesive resin cements used for fiber post cementation with fluid filtration method. Material and Method: In the study, 50 upper human canine teeth extracted for periodontal reasons were used. The root lengths of the teeth were mesured and standardized. Root canals were enlarged with rotary instruments (Protaper, Dentsply Maillefer, Ballaquies, Switzerland) and filling was achieved using lateral compaction technique. The specimens were randomly assigned to 5 groups (n=10). The fiber post (Exacto Glass Fiber posts, Angelus Industria de Produtos Odontologicos S/A, Londrina-PR-Brasil) cementations are completed with the fallowing materials: Variolink II Professional Pack (Ivoclar Vivadent, Liechtenstein) (Control), G-Cem Automix (GC, Tokyo, Japan), Panavia SA Cement (Kuraray, Okayama, Japan), Smart Cem 2 (Dentsply DeTrey GmbH, Konstanz, Germany) and Rely X U200 (3M ESPE, Neuss, Germany). The measurement of microleakage was performed at 2nd, 4th, 6th and 8th minutes. The data was analyzed by ANOVA and Tukey tests (p<0.05). Results: The best results were obtained in Rely X U200 and Panavia SA Cement groups, while the most leakage was seen in G-Cem Automix and Smart Cem 2 groups (p<0,05). There was statistically significant difference between Rely X U200 and Panavia SA Cement groups compared to the control group (p<0,05). The control group was found to have statistically less microleakage than G-Cem Automix and Smart Cem 2 groups (p<0,05). Conclusion: From the point of microleakage, some self adhesive resin cements used for fiber post cementation were found to be more reliable than the control group material

FİBER POST SİMANTASYONUNDA KULLANILAN SELF-ADEZİV REZİN SİMANLARIN MİKROSIZINTILARININ KARŞILAŞTIRILMASI

Abstract

Amaç: Bu çalışmanın amacı, fiber post simantasyonunda kullanılan dört self-adeziv rezin simanın mikrosızıntılarını sıvı filtrasyon yöntemi ile karşılaştırmaktır.

Gereç ve Yöntem: Çalışmada, periodontal nedenlerle çekilmiş 50 adet insan üst  çene kanin dişi kullanıldı. Dişlerin kök boyları ölçülerek standardize edildi. Dişler döner eğelerle (Protaper, Dentsply Maillefer, Ballaquies, İsviçre) genişletilip, lateral kompaksiyon yöntemiyle dolduruldu. Örnekler rastgele 5 gruba ayrıldı (n=10). Fiber post (Exacto Glass Fiber posts, Angelus Industria de Produtos Odontologicos S/A, Londrina-PR-Brezilya) simantasyonları şu materyallerle yapıldı:

Variolink II Professional Pack (Ivoclar Vivadent, Liechtenstein) (Kontrol), G-Cem Automix (GC, Tokyo, Japonya), Panavia SA Cement (Kuraray, Okayama, Japonya), Smart Cem 2 (Dentsply DeTrey GmbH, Konstanz, Almanya) ve Rely X U200 (3M ESPE, Neuss, Almanya). Mikrosızıntı ölçümleri 2, 4, 6 ve 8. dakikalarda gerçekleştirildi.

Veriler istatistiksel olarak ANOVA ve Tukey testleri ile değerlendirildi (p<0.05). 

Bulgular: En iyi sonuçlara Rely X U200 ve Panavia SA Cement’te rastlanırken, en fazla mikrosızıntı da G-Cem Automix ve Smart Cem 2’de gözlendi (p<0,05). Rely X U200 ve Panavia SA Cement grupları, kontrol grubuyla karşılaştırıldığında istatistiksel olarak anlamlı derecede daha sızdırmaz sonuçlar gösterdi (p<0,05). G-Cem Automix ve Smart Cem 2 grupları kontrol grubuyla karşılaştırıldığında, kontrol grubu bu gruplardan istatistiksel olarak daha sızdırmaz bulundu (p<0,05).

Sonuç: Fiber post simantasyonunda kullanılan bazı self-adeziv rezin simanlar, kontrol grubu materyaliyle karşılaştırıldığında mikrosızıntı açısından daha güvenilir bulundu.
