Özet
Amaç: Periodontal tedavi, kırık, restoratif uygulamalar, çürük gibi nedenlerle koruyucu tabakanın kalkması sonucu dentin tübülleri açığa çıkıp dişte hassasiyet oluşunca hassasiyet giderici ajanlardan yararlanılır. Çalışmamızın amacı; postoperatif diş hassasiyetini gidermek için kullanılan hassasiyet giderici ajanların, adeziv simantasyondaki bağlantıya etkisini incelemektir. Gereç ve Yöntem: 16 adet çürüksüz çekilmiş 3. büyük azı dişi rastgele iki gruba ayrıldı. Dişler PMMA bazlı soğuk akrilik içerisine yerleştirildi. Dişlerin okluzal yüzeyinde mine tabakası keskin frez ile kaldırılarak dentin tabakası açığa çıkartıldı. 1. gruptaki örneklere önce Gluma Desensitizer ve Gluma self etch bonding; sonra 4 mm çapında 3 mm yükseklikte silindir formunda SEcure adeziv siman uygulandı. 2. gruptaki örneklere ise önce Teethmate Desensitizer ve Clearfil universal bonding; sonra 4 mm çapında 3 mm yükseklikte silindir formunda SEcure adeziv siman uygulandı. Dentin örneklere termal siklus uygulandı. Hemen ardından örneklere üniversal test cihazında makaslama testi uygulandı. SEM incelenmesi ile desteklenerek elde edilen veriler istatiksel olarak değerlendirildi.Bulgular: Teethmate Desensitizer hassasiyet giderici ajanın makaslama dayanımı değeri Gluma ajanına göre daha düşük bulundu. Her iki grup arasında istatistiksel fark anlamlıdır.Sonuç: Gluma hassasiyet giderici ajan Teethmate Desensitizer'e göre daha yüksek bağlanma değeri gösterdi. Her iki grup içinde SEM analizinde koheziv kırıklar tespit edildi.
Aim: the aim of the study is to research the effect that link is in adhesive cementation of dentin desensitizing agent, which use to desensitizate prosperative dental. Materials and Methods: in this study, sixteen intact human third molar teeth were used. the teeth were randomly divided into two different groups (n: 8). Two different dentin desensitizer agents, Gluma and Teethmate Desensitizer, are used in the study. All samples were embedded into PMMA-based acrylic resin. the occlusal enamel tissues of teeth were removed to expose occlusal dentin. in the first group, firstly Gluma Desensitizer was applied to dentin surfaces according to manufacturer' instruction. Gluma self-etch was applied to dentin surfaces according to manufacturers' instructions. SEcure adhesive cement applied to dentin surface by means of cylindrical tubes. in the second group, firstly Teethmate Desensitizer was applied to dentin surfaces according to manufacturer' instruction. Clearfil universal bonding (Kuraray Medical Inc, Japan) was applied to dentin surfaces according to manufacturers' instructions. SEcure adhesive cement applied to dentin surface by means of cylindrical tubes. Shear bond strength test were performed by using Universal Tension/Compression Testing Machine (Instron 3382, USA).Results: the shear bond strength values of Teethmate Desensitizer groups were found statistically lower than the Gluma desensitizer groups (p<0.05). There was statistically significant difference between the groups.Conclusion: in this study, Gluma desensitizer shearbond strength values higher than Teethmate desensitizer. For both group, it is determined cohesive fractures in the SEM analysis.
