Abstract

Aim: The aim of this study was to compare the fluoride uptake from four different of fluoride releasing restorative materials by bovine enamel and to determine the effect of time on this uptake. Material and Method: A glass ionomer cement (Fuji II), resin-modified glass ionomer cement(Fuji II LC), giomer (Beautifil) and compomer (Dyract AP) were elected. A total of 120 bovine enamel slabs were prepared from the buccal surfaces of the bovine teeth. The slabs were divided into 5 subgroups (n=6) representing 5 time intervals (1, 7, 14, 21 and 35 days). Fluoride-ion selective electrode method was used to determine the enamel fluoride uptake was determined. Results: Glass ionomers and giomer had significantly higher fluoride uptake than compomer (p<0.05). Glass ionomers and giomer had similar fluoride uptake in all test intervals. Conclusion: Considering the enhanced physical properties and long-term fluoride release similar to glass ionomers, giomers are found to be promising

DÖRT FARKLI FLUORİD SALINIMI YAPAN RESTORATİF MATERYALDEN FLUORİD EMİLİMİNİN SIĞIR MİNESİNDE DEĞERLENDİRİLMESİ: İN VİTRO ÇALIŞMA

Abstract

Amaç: Bu çalışmanın amacı fluorid salınımı yapan 4
farklı tip restoratif materyalin sığır dişlerinin minesinde
flourid emilimini karşılaştırmak ve bu emilime zamanın
etkisini belirlemektir.
Gereç ve Yöntem: Çalışmada cam iyonomer siman
(Fuji II), rezin modifiye cam iyonomer siman (Fuji II
LC), giomer (Beautifil) ve kompomer (Dyract AP)
materyalleri kullanıldı. Sığır dişinin minesinin bukkal
yüzeylerinden toplam120 adet örnek hazırlandı.
Örnekler her bir materyal grubu için 5 zaman aralığını
(1, 7, 14, 21 ve 35 gün) temsil eden 5 alt gruba (n
=6) ayrıldı. Fluorid emilimini belirlemek icin florür
iyonu seçici elektrot yöntemi kullanıldı.
Bulgular: Cam iyonomerler ve giomer kompomere
göre (p <0.05) anlamlı olarak daha yüksek fluorid
emilimi gösterdi. Cam iyonomerler ve giomerin tüm
test aralıklarında benzer fluorid emilimi gösterdiği
belirlendi.
Sonuç: Giomerlerin gelişmiş fiziksel özellikleri ve cam
iyonomerlere benzer uzun süreli fluorid salınımı göz
önüne alındığında çocuk diş hekimliği için uygun bir
materyal olduğu bulgulanmıştır.
