Abstract

Aim: Bioactive glass has a wide range of medical
and dental applications and is a potential filler component for dental
restorative materials. The aim of this study was to examine the influence of
adding bioactive glass to glass ionomer based fissure sealant on its mechanical
properties and fluoride releasing ability.

Material and Methods: Two experimental groups were
prepared with BAG added to the powder component of the material at different
ratios of %30 (BAG30) and %10 (BAG10) by weight. The glass ionomer based
fissure sealant material without the addition of BAG was determined as the
control group. Cylindrical shaped specimens (8mm x 2mm) were prepared from each
group. Fluoride release, surface roughness and surface microhardness of the
specimens were measured and the data were statistically analyzed using one way
ANOVA and Wilcoxon Signed Rank tests.

Results: There was no difference between
fluoride releases of the materials except the first two days. BAG30 showed the
highest surface microhardness and surface roughness values. There was no
significant difference between surface microhardness values of BAG30 and BAG10.

Conclusion: The results of the study
showed that adding BAG did not adversely affect the mechanical and fluoride
release properties of glass ionomer based fissure sealants.

BİYOAKTİF CAM
İLAVE EDİLMİŞ CAM İYONOMER ESASLI FİSSÜR ÖRTÜCÜNÜN MEKANİK VE FLORİD SALINIM
ÖZELLİKLERİNİN ARAŞTIRILMASI

ÖZ

 Amaç:
Biyoaktif cam, medikal ve dental
uygula- malarda geniş bir kullanım alanına sahiptir ve dental restoratif
materyaller için potansiyel bir doldurucu bile- şendir. Bu çalışmanın amacı,
cam iyonomer esaslı fis- sür örtücüye biyoaktif cam ilave edilmesinin, materya-
lin mekanik ve florid salınım özellikleri üzerine etkilerini
araştırmaktır. 

Gereç
ve Yöntem: Cam iyonomer esaslı fissür
örtü- cünün toz kısmına ağırlıkça %30 (BAC30) ve %10 (BAC10) oranlarında
biyoaktif cam ilave edilerek iki farklı deney grubu elde edildi. Biyoaktif cam
ilave edilmeyen materyal ise kontrol grubu olarak belirlendi. Her grup için
(8mm X 2mm) silindir şeklinde örnekler hazırlandı. Tüm örneklerin florid
salınım değerleri, yü- zey pürüzlülükleri ve yüzey mikrosertlikleri belirlene- rek,
veriler tek yönlü ANOVA ve Wilcoxon Signed Rank testleri kullanılarak
istatistiksel olarak analiz edildi.

Bulgular:
İlk iki gün yapılan ölçümler
haricinde, tüm günlerde yapılan ölçümlerde materyallerden yapılan florid
salınım miktarları arasında anlamlı bir fark olmadığı bulundu. En yüksek yüzey
pürüzlülüğü ve yüzey mikrosertlik değerlerinin BAC30 grubunda oldu- ğu
gözlendi. BAC30 ve BAC10 gruplarında gözlenen yüzey pürüzlülüğü ve yüzey
mikrosertlik değerleri ara- sında istatistiksel olarak anlamlı bir fark
gözlenmedi.

Sonuç:
Çalışmadan elde edilen sonuçlar,
biyoaktif cam ilave edilmesinin cam iyonomer esaslı fissür örtücü materyalin
mekanik ve florid salınım özelliklerini olumsuz yönde etkilemediğini
göstermiştir.
