Abstract



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 (p<0.01). High viscosity
glass ionomer (GC EQUIA Fil) showed the least
microleakage
in both occlusal and gingival regions (p<0.001). However,
no statistically significant difference was found between the other restorative
glass ionomer cements (p>0.05). When the average microleakage values of each
restorative glass ionomer according to heat application are compared, there was
no statistically significant difference in both occlusal and gingival regions
(p>0.05). 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<0.05).



Conclusion: Heat
application in restorative glass ionomer cements used in the study reduced
microleakage even though there was no statistically significant difference.



Keywords: Glass ionomer
cement, heat application, microleakage.

Abstract



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 s
tereomikroskop görüntüleri
alınmıştır. Mikrosızıntı bir görüntü analiz programı ile (ImageJ) milimetrik
olarak ölçülmüştür. İstatistiksel analizler Kruskal-Wallis, Kolmogorov-Smirnov
ve Mann-Whitney U testleri ile yapılmıştır.



Bulgular:
Tüm restoratif cam iyonomerlerde gingival bölgede
okluzal bölgeden daha yüksek mikrosızıntı tespit edilmiştir (p<0,01).
Hem
okluzal hem de gingival bölgede en az mikrosızıntı yüksek viskoziteli cam
iyonomer simanda (GC EQUIA Fil) elde edilmiştir (p<0,001). Bununla birlikte,
diğer restoratif cam iyonomer simanlar arasında istatistiksel olarak anlamlı
bir farklılık bulunmamıştır (p>0,05).
Her
restoratif cam iyonomerin ısı uygulamasna göre ortalama mikrosızıntı değerleri
karşılaştırıldığında; hem okluzal hem de gingival bölgede ısı uygulaması
mikrosızıntıda istatistiksel olarak anlamlı bir farklılık yaratmamıştır (p>0,05).
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<0,05).



Sonuçlar: Çalışmada kullanılan
restoratif cam iyonomer simanlarda ısı uygulaması mikrosızıntı üzerinde istatistiksel
olarak anlamlı bir farklılık yaratmasa bile mikrosızıntıyı azaltmıştır.
