Abstract :ABSTRAC T   Aim: We evaluated the polymerization properties of mostly used three hard chairside reline materials and a self-cure acrylic resin. By polymerizing these materials in a device simulating an intraoral area, the setting time of polymerization, polymerization temperature and change in enthalpy were established. Material and Method: The denture-lining materials investigated were three hard chairside reline materials insert ignore into journalissuearticles values(Ufi Gel Hard, Elite Hard Relining, and GC Reline); and an autopolymerizing acrylic resin insert ignore into journalissuearticles values(SC Self-Cure Acrylic); at body temperature. The study was performed at Firat University, Faculty of Science. A sapphire differential scanning calorimetry device insert ignore into journalissuearticles values(Sapphire-DSC); was used to analyze the reline materials. Results: Statistically significant differences were observed among materials with respect to a change in enthalpy insert ignore into journalissuearticles values( p <0.001); and temperature insert ignore into journalissuearticles values( p <0.05); during polymerization. However, no significant difference was established for the setting time insert ignore into journalissuearticles values( p >0.05);. Conclusion: The Elite Hard Reline material showed the best results in all categories. Our results indicated that the enthalpy and temperature changes in the GC Reline sample was extremely high compared to the other hard chairside materials and self-cure acrylic sample. Keywords: Enthalpy change, hard chairside relining material, polymerization, self-cure acrylic resin DİŞHEKİMLİĞİ PRATİĞİNDE EN SIK KULLANILAN 3 FARKLI SERT BESLEME MATERYALİ VE 1 ADET OTO POLİMERİZAN AKRİLİK REZİNİN POLİMERİZASYON DEĞERLERİNİN ÖLÇÜLMESİ: BİR LABORATUVAR ÇALIŞMASI ÖZET   Amaç: Bu çalışmamızda 3 farklı sert besleme materyali ve 1 adet oto polimerizan akrilik rezin arasındaki polimerizasyon özellikleri karşılaştırıldı. Ağız içi ortamı taklit eden bir alet vasıtasıyla, polimerizasyon süresi, polimerizasyon sıcaklığı ve entalpideki değişiklik değerlendirildi.   Materyal ve Metot: Çalışmamızda 3 farklı sert besleme materyali insert ignore into journalissuearticles values(Ufi Gel Hard, Elite Hard Relining, and GC Reline); ve 1 adet oto polimerizan akrilik rezin insert ignore into journalissuearticles values(SC Self-Cure Acrylic); kullanıldı. Deney Fırat Üniver- sitesi Fen Fakültesi’nde gerçekleştirildi. Materyallerin analizinde, diferansiyel kalorimetri tarama cihazı insert ignore into journalissuearticles values(Sapphire-DSC); kullanıldı. Sonuçlar: Polimerizasyon esnasında entalpi değerin- deki insert ignore into journalissuearticles values( p<0.001 ); ve sıcaklık değerindeki insert ignore into journalissuearticles values( p<0.05 ); değişimlerde istatistiksel olarak anlamlı sonuçlar bulundu. Sertleşme süresi açısından insert ignore into journalissuearticles values( p>0.05 ); ise materyaller arasında herhangi bir istatistiksel fark bulunmamıştır. Tartışma: Elite Hard Reline sert besleme materyali bütün kategorilerde en iyi sonuçları göstermiştir. GC Reline sert besleme materyalinin entalpi ve sıcaklık değerlerinde göstermiş olduğu sonuçlar bütün diğer materyallere oranla oldukça yüksek bulunmuştur. Anahtar Kelimeler : Entalpi değişimi, sert besleme materyali, polimerizasyon, oto polimerizan akrilik rezin
