Abstract

Aim: The aim of this study was to assess the effect of topical fluoride applications on the surface microhardness of different glass ionomer based fissure sealants. Method: In this study different glass ionomer based fissure sealants were used (Fuji Triage, GCP Glass Seal, Fuji VII EP). 72 disc shaped specimens (8.0x2.5 mm) manufacturer’s instructions were photopolimerized with light source (Valo, Ultradent Products Inc, South Jordan, UT, USA), after stored in distilled water at 37°C for 24 hour initial microhardness measurements were performed with Vicker’s microhardness tester (Shimadzu Micro Hardness Tester HMV-2, Shimadzu Corporation, Kyoto, Japan). Specimens were randomly assigned to 2 experimental groups according to surface treatment regimens consisting of 2% NaF gel (Sultan Topex neutral pH gel, Sultan Dental Products, USA) and 1.23%APF gel (Sultan Topex APF gel, Sultan Dental Products, USA) and these groups were assigned to 3 experimental subgroups according to application types (1 minute gel application, 4 minute gel application, 4x4 minute gel application). After applications; specimens were rinsed with distilled water and microhardness measurements were repeated.Statistical analysis were made with repeated measures ANOVA and Bonferroni correction (=0.05).Result: It has been found that the types of applied agents, time of application and repeated applications reduce the hardness values of fissure sealant material, but the difference was not statistically significant (p > 0.05). Conclusion: Microhardness values of the different content fissure sealants used in the study were found not to be affected by topical fluoride applications

Özet

Amaç: Bu çalışmanın amacı, topikal flor uygulama- larının farklı içeriklerdeki cam iyonomer esaslı fissür örtücü materyallerin mikrosertlikleri üzerine olan etkilerinin incelenmesidir.Metot: Çalışmada farklı içeriklere sahip cam iyonomer esaslı 3 adet fissür örtücü materyal kullanıldı (Fuji Triage, GCP Glass Seal, Fuji VII EP). Üretici firmaların talimatları doğrultusunda disk şeklinde hazırlanan 72 adet örnek (8.0x2.5 mm), ışık tabancası (Valo, Ultradent Products Inc, South Jordan, UT, USA) ile polimerize edildi, 24 saat 37ºC’de, deiyonize su içerisinde bekletildikten sonra başlangıç mikrosertlik ölçümleri Vicker’s mikrosertlik test cihazı (Shimadzu Micro Hardness Tester HMV-2, Shimadzu Corporation, Kyoto, Japan) ile gerçekleştirildi. Ölçümleri tamam- lanan örnekler, rastlantısal olarak %2’lik NaF (Sultan Topex neutral pH gel, Sultan Dental Products, USA) ve %1,23’lük APF’nin (Sultan Topex APF gel, Sultan Dental Products, USA) uygulandığı 2 gruba bu gruplar da kendi içerisinde uygulama şekillerine göre 3 alt gruba ayrıldı (1dk jel uygulaması, 4 dk jel uygulaması, 4x4 dk jel uygulaması). Uygulama sonrası örnekler deiyonize su ile yıkandı ve mikrosertlik ölçümleri tek- rarlandı. İstatistiksel analizler, tekrarlanan ölçümlü ANOVA testi ve Bonferroni düzeltmesi ile gerçek- leştirildi (a = 0.05).Bulgular: Uygulanan ajanın türü, uygulama süresi ve tekrarlayan uygulamaların, fissür örtücü materyallerin mikrosertlik değerlerini düşürdüğü ancak elde edilen değerler arasında istatistiksel olarak anlamlı bir fark olmadığı bulunmuştur (p > 0.05).Sonuç: Çalışmada kullanılan farklı içeriklere sahip fissür örtücülerin yüzey sertlik değerlerinin çalışmada kullanılan topikal flor uygulamalarından etkilenmediği görülmüştür.
