ABSTRACT

This study was carried out to evaluate the microleakage of Class II cavities restored with various types of lining materials. Four types of composite resins (Esthet-X-Denstply, USA, FiltekTMZ350-3M ESPE, USA, Beautifil- Shofu, Japan and Solare P-GC, Japan) were used and the lining were the Fuji IXGP (GC, Japan), the Beautifil flow (Shofu, Japan), the FiltexTMZ350 flow (3M ESPE, USA) and the Esthet-X flow (Denstply, USA). All the specimens were thermocycled and immersed in 0.5% basic fuschin dye for 24 h. The microleakage was scored using the ISO microleakage scoring system. The data were entered using SPSS version 12.0 and analyzed using STATA software programme. This study showed that none of the materials used in this study was able to eliminate microleakage. However, it was shown that the glass ionomer cement was better in reducing the incident of microleakage at the cervical margin. Among the flowable composite resin, FiltexTMZ350 flow showed less microleakage at the cervical margin.

ABSTRAK

Penyelidikan ini dilakukan untuk menilai kebocoran mikro dalam pemulihan Kelas II yang ditampal dengan berbagai jenis bahan pelapik tampalan. Empat jenis resin komposit (Esthet-X-Denstply, Amerika Syarikat, FiltekTMZ350-3M ESPE, Amerika Syarikat, Beautifil-Shofu, Jepun dan Solare P-GC, Jepun) digunakan dan bahan pelapik tampalan yang digunakan adalah Fuji IXGP (GC, Jepun), Beautifil flow (Shofu , Jepun), Filtex flow TMZ350 (3M ESPE, USA) dan Esthet-X flow (Denstply, USA). Semua spesimen yang diuji melalui proses kitaran terma dan direndam dalam 0.5% pewarna asas fuschin selama 24 jam. Data kebocoran mikro bagi pemulihan ini berasaskan sistem pemarkahan ISO kebocoran mikro. Data ini dimasukkan dengan menggunakan SPSS 12.0 dan dianalisis menggunakan program perisian STATA. Kajian ini menunjukkan bahawa tidak ada bahan pelapik yang digunakan mampu menghalang kebocoran mikro tampalan. Namun begitu, kajian ini menunjukkan bahawa penggunaan bahan berasaskan kaca ionomer mampu mengurangkan kebocoran mikro bagi pemulihan Kelas II. Antara resin flowable komposit, Filtex flow TMZ350 telah menunjukkan pengurangan kebocoran mikro apabila digunakan sebagai pelapik untuk pemulihan Kelas II.

 

Kata kunci: Kaca ionomer; kebocoran mikro; komposit resin flowable; pemulihan Kelas II
