ABSTRACT



 



Aim: The current study
investigated the thermal conductivity of dimethacrylate- and
silorane-based composite resins at different polymerization times and modes.



Materials and Method: Forty
dentin discs (8 mm diameter, 1.5 mm thick) were obtained from caries-free human
molar teeth. Filtek Silorane (3M ESPE, Minnesota, USA) and Filtek Z550 (3M
ESPE, Minnesota, USA) composite were polymerized with a  LED (Light-Emitting-Diode) curing device
(Valo,

Ultradent Products Inc., Utah, USA
), in two modes in different times (xtra power mode, 3200 mW/cm2;
3-, 6-, 9-, 12-, +2 s / standard mode 1000 mW/cm2, 10-, 20-, 30-,
40-, +2 s)(n=10). Temperature changes in the dentin discs were measured with a
K-type thermocouple (
E-680, Elimko Co., Ankara, Turkey) and
recorded. Data were statistically analyzed using Analysis of variance and
independent sample t test (α=0.05)



Results: Mean
temperature changes were significantly different among polymerization times and
modes (p<0.05). Temperature change of Filtek Silorane were significantly
higher than Filtek Z550 for each time interval and curing mode (p<0.05).



 Conclusion: As the polymerization time
increases, the temperature increase in the dentin may adversely affect to the
pulp health.

ÖZ



Amaç: Bu
çalışmada siloran-esaslı ve dimetakrilat-esaslı kompozitlerin farklı
polimerizasyon sürelerinde ve modlarında termal iletkenlikleri değerlendirildi



Gereç ve Yöntem:
Sağlam insan üçüncü molar dişlerinden 40 dentin disk (8 mm çap, 1.5 mm
kalınlık) hazırlandı. Filtek Silorane (3M ESPE Dental Ürünleri, Minnesota, ABD)
ve Filtek Z550 (3M ESPE Dental Ürünleri, Minnesota, ABD) kompozit örnekleri,
led ışık cihazı ile (Valo, Ultradent Products Inc., Utah, ABD) iki farklı modda
ve farklı sürelerde (xtra power mod, 3200 mW/cm2; 3, 6, 9, 12 +2 sn
/ standard mod 1000 mW/cm2, 10, 20, 30, 40, +2 sn) polimerize
edildi. Dentin örneklerindeki sıcaklık artışı, K tipi termokapıl (E-680, Elimko
Co., Ankara, Türkiye) kullanılarak ölçüldü. Her zaman aralığı arasındaki ölçüm
farkları (ΔT) kaydedildi. Veriler ANOVA ve bağımsız örneklem t-testi ile analiz
edildi. (α = 0.05)



Bulgular:
Farklı polimerizasyon süreleri ve modları arasında ortalama sıcaklık artışları
açısından anlamlı farklılıklar tespit edildi (p <0.05). Filtek Silorane
kompozitin polimerizasyonu sırasında tüm modlar ve zaman aralıklarında Filtek
Z550'ye kıyasla anlamlı derecede daha yüksek sıcaklık artışı görüldü (p
<0.05).



Sonuç: Polimerizasyon
süresi arttıkça dentindeki ısı artışı pulpa sağlığını olumsuz etkileyebilir.



Anahtar Kelimeler: Termal iletkenlik, dental komozit rezin, LED ışık
cihazı, Polimerizasyon süresi
