Farklı tipteki restoratif cam iyonomer simanların mikrosızıntı üzerine ısı uygulanmasının etkisi

Amaç: Bu in vitro çalışmanın amacı, farklı tipteki restoratif cam iyonomer simanlara ısı uygulanmasının mikrosızıntı üzerine etkisini değerlendirmektir. Gereç ve Yöntemler: Çalışma için toplam 112 adet çürüksüz süt ikinci azı dişinin hem bukkal hem de lingual/palatinal yüzeylerine standart sınıf V kaviteler (4X2X2 mm) açılmış ve dört farklı tipteki restoratif cam iyonomer siman [geleneksel cam iyonomer (GC Fuji IX), rezin modifiye cam iyonomer (GC Fuji II LC), yüksek viskoziteli cam iyonomer (GC EQUIA Fil) ve cam karbomer (GCP Glass Fill)] ile restorasyonlar yapılmıştır. Her restoratif cam iyonomer siman ısı uygulamasına göre 4 gruba (kontrol, 20 s, 40 s ve 60 s ısı uygulaması) ayrılmıştır. Dişler termal siklus uygulanmasını takiben rutin boya ve kesit alımı işlemlerine tabi tutularak stereomikroskop görüntüleri alınmıştır. Mikrosızıntı bir görüntü analiz programı ile (ImageJ) milimetrik olarak ölçülmüştür. İstatistiksel analizler Kruskal-Wallis, KolmogorovSmirnov ve Mann-Whitney U testleri ile yapılmıştır. Bulgular: Tüm restoratif cam iyonomerlerde gingival bölgede okluzal bölgeden daha yüksek mikrosızıntı tespit edilmiştir (p0,05). Bununla birlikte, okluzal bölgede cam karbomer (GCP Glass Fill), gingival bölgede ise yüksek viskoziteli cam iyonomer (GC EQUIA Fil) hariç diğer tüm restoratif cam iyonomerlerde 60 s ısı uygulaması yapıldığında mikrosızıntı değerlerinde kontrol grubuna göre anlamlı bir düşüş tespit edilmiştir (p

The effect of heat applıcatıon on the mıcroleakage of dıfferent types of glass ıonomer cements

Background: The purpose of this in vitro study is to evaluate the effect on the microleakage of heat application in different types of restorative glass ionomer cements. Methods: For the study, standard class V cavities (4X2X2 mm) were prepared on both buccal and lingual / palatal surfaces of a total of 112 non-carious decidious second molar teeth and restorations were made with four different types of restorative glass ionomer cements [conventional glass ionomer (GC Fuji IX), resin modified glass ionomer (GC Fuji II LC), high viscosity glass ionomer (GC EQUIA Fil) and glass carbomer (GCP Glass Fill)]. Each restorative glass ionomer cement was divided into 4 groups (control, 20 s, 40 s and 60 s heat application) acording to heat application. Following thermal cycling, the teeth were subjected to routine dye and cross-sectional procedures and images were taken under stereomicroscope. Microleakage assessment was measured in millimeters by an image analysis program (ImageJ). Statistical analyzes were performed with Kruskal-Wallis, Kolmogorov-Smirnov and Mann-Whitney U tests. Results: In all restorative glass ionomers, microleakage higher than the occlusal region in the gingival region was detected (p0.05). However, a significantly decrease in microleakage values compared to the control group was observed when 60s heat application in all other restorative glass ionomers except for the glass carbomer (GCP Glass Fill) glass in the occlusal region and the high viscous glass ionomer (GC EQUIA Fil) in the gingival region (p
