Abstract

Background and Aim: The aim of this in vitro study was to evaluate the effects of different hypersensitivity treatments on the shear bond strength of flowable adhesive composite resin to dentin. Materials and Methods: The whole dentin specimens were etched to remove any smear plugs and to mimic the open dentinal tubules of sensitive dentin using 0.5 M EDTA (pH 7.4) for two minutes: Forty dentin specimens were randomly divided into four groups (n=10) (1) Group C (control); (2) Group N (treated with Nd:YAG laser); (3) Group G (treated with Gluma Desensitizer); (4) Group N+G (treated with Nd:YAG laser following Gluma Desensitizer). Flowable composite resin cement was applied to dentin surface and shear bond strength tests were performed. The mean SBS values were evaluated, failure modes were determined, and data were analyzed by one-way ANOVA test and compared with Tukey HSD test. Results: There was significant difference among Group G (11.7±4.6 MPa) and Group N (18.5±2.5 MPa) (p=0.05). There were no significant differences among the other groups. SEM evaluation revealed that Group N occluded open dentinal tubules in some areas by melting and modifying of dentin tubule periphery. Group G showed prominent narrowing and reduction in the diameter of the affected tubules. Group N+G occluded dentinal tubules to varying degrees. Conclusion: Nd:YAG laser treatment following Gluma Desensitizer could be an effective treatment for dentin hypersensitivity and does not affect the bond strength of adhesive composite resin to dentin surface detrimentally.

Özet

Amaç: Bu invitro çalışmanın amacı farklı duyarlılık tedavilerinin, adeziv akışkan kompozit rezinin dentine makaslama bağlanma dayanıklılığı üzerine etkilerini değerlendirmekti. Gereç ve Yöntem: Tüm dentin örnekleri, smear tabakasını uzaklaştırmak ve hassas dentin yüzeylerini taklit edecek şekilde dentin tübüllerini açmak için 0,5 EDTA ( pH 7.4) ile iki dakika pürüzlendirildi: Kırk örnek rastgele dört gruba ayrıldı (n=10) (1) Grup C (kontrol); (2) Grup N (Nd:YAG lazer tedavisi); (3) Grup G (Gluma Hassasiyet giderici tedavisi); (4) Grup N+G (Gluma hassasiyet giderici uygulamasının ardından Nd:YAG lazer tedavisi). Dentin yüzeyine akışkan kompozit rezin uygulandı ve makaslama bağlanma dayanıklılık testi uygulandı. Ortalama MBD değerleri değerlendirildi, kırılma tipleri belirlendi ve veriler tek-yönlü ANOVA ile analiz edilip Tukey HSD testi ile karşılaştırıldı. Bulgular: Grup G (11,7±4,6 MPa) ve Grup N (18,5±2,5 MPa) arasında anlamlı fark bulundu (p=0.05). Diğer gruplar arasında anlamlı fark gözlenmedi. SEM değerlendirmesi, Grup N’nin bazı bölgelerde, dentin tübüllerinin periferini modifiye ederek ve eriterek açık dentin tübüllerini tıkadığını gösterdi. Grup G’de etkilenen tübüllerin çapında azalma ve belirgin daralma gözlendi. Grup N+G, dentin tübüllerini değişen derecelerde tıkadı. Sonuç: Gluma hassasiyet giderici ardından Nd:YAG lazer uygulaması, dentin hassasiyeti için etkili bir tedavi olabilir ve adeziv kompozit rezinin dentin yüzeyine bağlanma dayanıklılığını olumsuz yönde etkilemez.
