Öz

Amaç: Bu
çalışmanın amacı demir sülfat ile kontamine süt dişi dentinine 3 farklı
self-etch adeziv sistemlerin asitli ve asitsiz uygulamalarını takiben
yerleştirilen kompomerin mikrogerilim bağlanma dayanımlarını değerlendirmektir.

Materyal-Metod:
45
adet çürüksüz insan süt II. azı dişinin kuronları, okluzalden dentin yüzeyi
açığa çıkacak şekilde yatay yönde uzaklaştırılmış ve eşit sayıda rastgele 3
gruba ayrılmıştır. Grup I: kontrol, Grup II: demir sülfatla kontamine, Grup III:
demir sülfatla kontamine asit uygulanan grup. 
Her bir grup kendi içinde 3 farklı adeziv ajan (Clearfil SE-Bond, 3M-ESPE
Single Bond Universal, Tokuyama Bond Force)
için 3 alt gruba ayrılmıştır. Grup II ve III’teki dişler insan kanıyla
kontamine edildikten sonra 30 sn demir sülfat uygulanmış ve 30 sn süreyle serum
fizyolojik ile yıkanmıştır. Grup III’e 
%34,5’ lik fosforik asit 15 sn uygulanmıştır. Tüm gruplara adeziv uygulaması
ve kompomer restorasyonu sonrası, dişler 1x1 mm kalınlığında kesilerek her
dişten 3’er adet test çubukları elde edilmiştir. Çubuklara mikrogerilim testi
uygulanmıştır. Oluşan kırık tipleri (adeziv, koheziv, karışık) steromikroskopta
belirlenmiştir. Verilerin değerlendirilmesinde tek yönlü varyans analizi ve
Post-hoc çoklu karşılaştırma testleri kullanılmıştır.

Bulgular: En
düşük mikrogerilim değeri Grup II’de iken (p<0,05), en başarılı adeziv Grup
I ve II de Clearfil SE-Bond bulunmuştur.

Sonuç: Demir
sülfat, süt dişi dentininde self-etch adezivlerin bağlanma performansları
üzerine negatif etkiye sahip olup, asit uygulaması bu etkiyi azaltmaktadır.

Anahtar Kelimeler: Bağlanma
dayanımı, demir sülfat, kontaminasyon.

COMPARING OF MICROTENSILE BOND STRENGTH OF THREE
DIFFERENT SELF-ETCH ADHESIVE SYSTEMS TO PRIMARY TOOTH DENTINE CONTAMINATED WITH FERRIC SULPHATE^≠

ABSTRACT

Aim: The aim of this study was to evaluate the microtensile
bond strengths of compomer placed to primary dentin contaminated with ferric
sulphate following the application of three different acidic and acid-free
self-etch adhesive systems.

Materials
and method: 45
non-carious second primary molars human teeth were cut horizontally so as to be
released the occlusal dentin surface. Teeth were randomly divided into 3 groups
with equal numbers. Group I: control, Group II: contaminated with ferric
sulphate, Group III: exposed to acid contaminated with ferric sulphate. Each
group was divided into 3 subgroups for 3 different adhesive agents (Clearfil
SE-Bond, 3M-ESPE Single Bond Universal, Tokuyama Bond ForceII). After the teeth
were contaminated with human blood in group II and III, ferric sulphate was
applied to teeth for 30 seconds and they were rinsed with physiological se- rum
for 30 seconds. 34.5% phosphoric acid was applied to teeth in group 3 for 15
seconds. After the application of adhesive and compomer restoration to all
groups, 3 test
sticks from each tooth
were obtained by cutting the teeth to 1x1mm. Microtensile test was applied to
the strips and fracture types (adhesive, cohesive, mixed) obtained were
determined at stereomicroscope. The data were analyzed by one-way ANOVA and
Post-Hoc test.

Results:
The
lowest value of microtensile has been found in Group II (p<0.05). The most
successful adhesive was Clearfil SE-Bond in Group I and Group II.

Conclusion:
Ferric
sulphate has a negative effect on bonding performance of self-etch adhesives at
primary dentine and acidic applications reduce this effect.
