Özet
Bu çalışmanın amacı, klinikte sık kullanılan restorasyon materyallerinin zaman içindeki ağırlık değişimlerini belirlemektir. Bu amaçla çalışmada, üç çeşit ışıkla sertleşen kompozit esaslı rezin (3 M Valux Plus, 3 M; Admira, Voco; Tetric - Ceram, Vivadent), iki çeşit konvansiyonel cam iyonomer siman (Keta -Fil, ESPE; Ketac - Silver, ESPE), bir çeşit ışıkla sertleşen resin modifiye cam iyonomer siman (Photac - Fil, ESPE), bir çeşit ışıkla sertleşen poliasit modifiye kompozit rezin (Hytac, ESPE), birisi kapsüllü olmak üzere iki çeşit amalgam (Cavex, Cavex), bir çeşit porselen inley (Empress, Ivoclor) kullanıldı. Her bir materyalden 4 mm çapında 8 mm uzunluğunda altışar tane silindir hazırlandı. Distile su içinde saklanan örneklerin 1,7, 15,30, 90 ve 180 günlük ağırlık ver hacim ölçümleri 10~4 hassasiyetle ölçüm veren hassas terazi (Gec Avery, England) ile yapıldı. Daha sonra her bir örneğin özgül ağırlığı hesaplandı. Elde edilen veriler Wilcoxon Signed Ranks Test, Bonferroni ve Kruskall Wallis Testleri kullanılarak değerlendirildi. Çalışma grupları arasındaki farkın anlamlı olduğu (P < 0.005) ardışık zamanların farklı etkileri olduğu saptandı. Çalışmaya göre klinikte sık olarak kullanılan restorasyon materyalleri ağız ortamı ile sıvı alışverişinde bulunmaktadırlar.
The objective of this study was to assess the specific weight changes of different restorative materials used frequently in the clinic, by time. In this study ten kinds of restorative materials were studied. Three composite resins (3 M Valux Plus, 3 M; Admira, Voco; Tetric -Ceram, Vivadent), two conventional glass ionomer cements (Keta - Fil, ESPE; Ketac -Silver, ESPE), a resin modified glass ionomer cement (Photac - Fil, ESPE), a polyacid modified composite resin (Hytac, ESPE), two amalgams whose one each was in form as capsule (Cavex, Cavex), a porcelain inley material (Empress, Ivoclor) were compared. Six specimen of each material prepared as a cylinder shape in 8 mm height and 4 mm diameter. Weight and volume measurements of each specimen stored in distilled water were performed at 1 st, 7 th, 15 th, 30 th and 90 th days and marked by using 10^ paired very sensitive balance (Gec Avery, England). Specific weight of specimens were calculated at above mentioned days. Obtained data were analysed by using Wilcoxon Signed Ranks Test, Bonferroni and Kruskall Wallis Tests. We observed that differences between the study groups were statistically significant and effect of sequent times are differents. According to this study fluid transmission exists between the restorative materials which used frequently in the clinic and the oral environment.
