Effects of NanoAg‐ACP Microparticles as Bioactive Fillers on the Mechanical and Remineralization Properties of Dental Resin Cement

Introduction: The degree of polymerization of dental resin cement materi- als is very important for the longevity and quality of the clinical success of the restorative procedure. Insufficiently effective polymerization reaction of dental resin cement materials may result in adverse effects on the mechanical and adhesive performance of the material. It is believed that the proportion of triethylene glycol dimethacrylate (TEGDMA) mono- mers in the chemical structure of the material significantly influences the polymerization reaction. With the increase in TEGDMA, the degree of conversion of monomers into the polymer increases. Aim: The aim of this study has been to determine the degree of polymerization of dual cure dental resin cement. Material and methods: For the analysis of the degree of polymerization, Fourier transform infrared (FTIR) spectroscopy was used. 10 samples of dual cure resin based cement Variolink II were prepared in accordance with the manufacturer's instructions. Analysis was performed 24 hours after polymerization procedure. Results: Degree of polymerization of Variolink II resin based cement ranged from 69.2% to 98.7% with a mean value of 85.81%. Conclusion: Variolink II dual cure resin cement contains a significant percentage of TEGDMA which can be the cause of high degree of polymerization. The minimum accep- table percentage of the degree of polymerization of dental resin cement has not yet been established.

Ceramic Restorations

The demand from patients for aesthetic in posterior teeth restoration has been increasing in recent years. As an alternative to metal alloy restorations used in posterior tooth, aesthetical materials such as ceramics have been more often utilized. Resin cement, a derivative from dental composite, based on the combination of bis-GMA and inorganic filler is used to fixate these ceramic restorations to posterior teeth. Similar to resin composite, incorporated antibacterial agents to resin cement can be an effective way to increase the aesthetic restoration durability. Resin cements C&B® (Bisco) and Fill Magic Dual Cement® (Vigodent) were used in the present study. For experimental resin cement, Triclosan was incorporated to the base cement paste. Samples were investigated by Scanning Electron Microscopy coupled to EDX microprobe (SEM/EDX) and FTIR spectroscopy. The results have demonstrated that the incorporation of antibacterial agents to resin cement is possible through the developed procedure.
