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
