THERMAL CONDUCTIVITY OF DIFFERENT COMPOSITE RESIN MATERIALS IN DIFFERENT POLYMERIZATION TIMES AND MODES

Öz

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.

Key Words: Thermal conductivity, dental composite resin, LED curing unit, polymerization time

FARKLI KOMPOZIT REZIN MATERYALLERIN FARKLI KÜRLEME SÜRELERINDE VE MODLARINDA TERMAL ILETKENLIKLERI

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.
