In Vitro Evaluation of Temperature of Pulp Chamber During Composite Resins Polymerization

Year 2005, Volume: 32 Issue: 3 - Volume: 32 Issue: 3, 163 - 169, 01.08.2005

Abstract

The purpose of this in vitro study was to evaluate temperature changes into pulp chamber during composite resin polymerization. 40 extracted human maxillary central teeth were used. Standardized cavities 5mm diameter and 2 mm height were prepared to vestibul surface of each tooth, and the teeth were randomly divided into 4 groups each containing 10 teeth. Apexes of all of the teeth were cut approximately 4 mm apical of the cemento-enamel junction and pulp tissue was removed with hedström files. Thermocouple of a digital thermometer was placed into the pulp chamber of each tooth and controlled with radiography. A flowable Tetric-Flow , a packable Surefil , a hybrid Charisma and an organic modified ceramic based Admira composite resins were applied to these cavities and polymerized with a light-cure devices for 40 s. The increase of temperature was recorded during polymerization. Results were statistically evaluated with Analysis of Variance and Duncan test. The highest increase of temperature was observed in flowable composite group. Statistically significant differences were not found among the other composite groups p

Dişlerin kökleri mine-sement birleşiminden yaklaş›k olarak 4 mm aşağ›da olacak şekilde kesildi, pulpa dokusu headström eğeler ile uzaklaşt›r›ld›. Her dişin pulpa odas›na digital termometrenin termocouple’› yerleştirildi ve radyografi ile kontrol edildi. Daha sonra bir ak›şkan Tetric-Flow , bir kondanse edilebilir Surefil ,bir hybrid Charisma ve bir ormoser esasl› Admira kompozit rezinler kavitelere yerleştirilerek 40 s ›ş›k cihaz› ile polimerize edildiler. Polimerizasyon esnas›ndaki ›s› art›şlar› kaydedildi. Sonuçlar istatistiksel olarak Varyans Analizi ve Duncan testi ile değerlendirildi. En yüksek ›s› art›ş› ak›şkan kompozit grubunda gözlendi. Diğer kompozit rezinler aras›nda istatistiksel olarak önemli farkl›l›k bulunmad›. p
