Abstract

The aim of this in vitro study was to investigate the effect on the micro leakage of using cavity varnish on dentin surfaces where smear layer is removed or modified. In this study 60 extracted molar teeth without any caries were used. Black I cavities were prepared and the teeth were randomly divided into 6 groups. Every group was restored with the following restorative techniques 1- Amalgam (Control Group) 2- Cavity varnish application + amalgam 3- EDTA % 17 application to dentin + amalgam 4- EDTA. %17 application to dentin + cavity varnish application + amalgam 5- Self - etching primer application to dentin + amalgam 6- Self - etching primer application to dentin + cavity varnish application + amalgam The specimens were stored for a week in distilled water at 37° C. After thermocycling 100x between 5±2°C and 60+2 °C, the teeth were coated with double layer of nail varnish and wax except for 1 mm around the restorations. The specimens were then immersed in 0.5 % basic fuchsin solution for 24 hours and then sectioned. The specimens were examined under stereomicroscope The results concluded that using cavity varnish on dentin surfaces where smear layer was removed or modified reduced early micro leakage in amalgam restorations significantly

Özet

Bu in vitro çalışmanın amacı ; denlinde smear tabakanın kaldırılarak veya modifiye edilerek kavite verniği uygulamasının mikrosızıntı üzerindeki etkisini incelemektir. Bu çalışmada çekilmiş, çürüksüz 60 adet molar diş kullanıldı. Dişler üzerinde Black I kaviteler hazırlandı ve dişler rastgele 6 gruba ayrıldı. Her grup aşağıdaki şekilde restoratif tekniklerle restore edildi;l Amalgam, (kontrol) 2- Kavite verniği uygulaması + Amalgam 3- Denlin yüzeyine % 17'lik EDTA uygulaması + Amalgam 4- Denlin yüzeyine % 17'lik EDTA uygulaması + Kavite verniği uygulaması + Amalgam 5- Denlin yüzeyine self - etching primer uygulaması + Amalgam 6- Denlin yüzeyine self etching primer uygulaması + Kavile verniği uygulaması + Amalgam Restore edilen örnekler l hafta süre ile 37° C'de distile suda bekletildi. Daha sonra örneklere 5±2°C ve 60±2°C'de 100 kez termal siklus uygulandı ve örnekler restorasyonun l mm dışından iki kat tırnak cilası ile kaplandı ve % 0.5'lik bazik fuksin içinde 24 saat bekletildi. Kesitleri alınan örnekler stereomikroskop altında incelendi Sonuç olarak amalgam restorasyonlarda smear tabakasını uzaklaştırdıktan veya modifiye ettikten sonra kavite verniği uygulamasının erken dönemdeki mikro sızıntıyı elimine ettiği bulgulanmıştır
