Activation of matrix-bound endogenous proteases by self-etch adhesives
Oğuz Ahmet, Bebek Serra; Şeşeoğulları Dirihan, Roda; Tezvergil Mutluay, Arzu (NLM (Medline), 2020)The study evaluated changes in total enzymatic activity and degradation of demineralized dentin following the application of universal or self-etch adhesives. The universal adhesives -Scotchbond Universal (SU) and All-Bond ... -
Addition of benzalkonium chloride to self-adhesive resin-cements: Some clinically relevant properties
Oğuz Ahmet, Serra; Mutluay, Mustafa Murat; Seyfioǧlu Polat, Zelal; Seseoğulları-Dirihan, Roda; Bek, Bülent; Tezvergil-Mutluay, Arzu (Informa Healthcare, 2014)OBJECTIVE: The clinical survival rates of the adhesive restorations are limited due to the deterioration of resin-dentin bonds over time, partly due to the endogenous enzymatic activity of dentin. Recently, benzalkonium ... -
Effect of acid or laser treatment on degradation of dentin matrix
Üşümez, Aslıhan; Sarı, Tuğrul; Şeşeoğulları Dirihan, Roda; Güven, Mehmet Esad; Oğuz Ahmet, Serra; Gutknecht, Norbert; Tezvergil Mutluay, Arzu (Springer, 2022)Purpose: The objective of this study was to determine the effect of dental laser (DL) irradiation on the metalloproteinases (MMP)-mediated dentin collagen degradation. Methods: Human dentin disks were prepared (0.3 × 5x6mm, ... -
Effect of combined surface treatments on surface roughness and resin bond strength to Y-TZP ceramic and nickel-chromium metal alloy
Sayın Özel, Gülsüm; Okutan, Yener; Oğuz Ahmet, Bebek Serra; Özdere, Eda (Mary Ann Liebert Inc., 2019)Objective: This study compared the effects of different surface treatments on the surface roughness (Ra), and shear bond strength (SBS) of resin cement to yttria-stabilized tetragonal zirconia (Y-TZP) ceramic and nickel-chromium ... -
Effect of gallic acid addition on some mechanical properties of self-adhesive resin cements
Oğuz Ahmet, Bebek Serra; Sayın Özel, Gülsüm; Mutluay, Mustafa Murat; Tezvergil-Mutluay, Arzu (NLM (Medline), 2019)Self-adhesive resin cements (RCs) activate matrix metalloproteinase (MMP) and cathepsin-related collagen degradation, and gallic acid (GA) inhibits the activity of both MMPs and cysteine cathepsins. The purpose of this ... -
Effect of thermocycle and bonding agents on the bond strength of titanium-resin cements
Sayın Özel, Gülsüm; Akın, Ceyda; Oğuz Ahmet, Bebek Serra (Bezmiâlem Vakıf University, 2021)Objective: This research aimed to evaluate the effect of different resin cement (RC) types, compare the effect of surface treatments and bonding applications and evaluate the effect of thermal cycling on bond strengths to ... -
Effects of glazing procedures on the color stability of conventional and CAD/CAM hybrid ceramics: A comparative study
Özyılmaz, Özgün Yusuf; Sayın Özel, Gülsüm; Oğuz Ahmet, Bebek Serra (Galenos Yayıncılık, 2019)Objective: Ceramic glazing and polishing are important for patient satisfaction and long-term clinical success. Till date, no study has compared color changes after glazing procedures between conventional and more recently ... -
Fabrication of a screw-retained hybrid prosthesis following treatment of peri-implant defects: A case report
Uslu Toygar, Hilal; Sayın Özel, Gülsüm; Oğuz Ahmet, Bebek Serra (Istanbul University Press, 2016)The etiology of marginal bone loss around osseointegrated implants is primarily based on the biomechanical and/or microbial factors. If stresses and strains around dental implants under functional loading conditions are ... -
