“…Usually, they are powdered and then mixed, in small amounts, with a dry potassium bromide (KBr) powder [18,29,45,59,90,92,[98][99][100][101][102]. In recent works attenuated total reflection (ATR) sampling technique was effectively used for the DC determination [85,91,[103][104][105][106][107][108]. The main advantage of the ATR-FTIR is simplicity in sample processing.…”

“…The dimethacrylate group provides bands in the FTIR spectra at 1637 cm −1 , referring to the C=C stretching vibrations [18,29,54,85,[90][91][92][98][99][100][103][104][105][106][107][108][109][110][111][112][113][114][115][116][117][118][119][120], 948 cm −1 -referring to the =CH 2 wagging and 816 cm −1 -referring to the =CH 2 twisting [112]. Since the peak at 1637 cm −1 is stronger [112], it is most commonly used.…”

Material characterization by the determination of relationships between structure and properties at different scales is essential for contemporary material engineering. This review article provides a summary of such studies on dimethacrylate polymer networks. These polymers serve as photocuring organic matrices in the composite dental restorative materials. The polymer network structure was discussed from the perspective of the following three aspects: the chemical structure, molecular structure (characterized by the degree of conversion and crosslink density (chemical as well as physical)), and supramolecular structure (characterized by the microgel agglomerate dimensions). Instrumental techniques and methodologies currently used for the determination of particular structural parameters were summarized. The influence of those parameters as well as the role of hydrogen bonding on basic mechanical properties of dimethacrylate polymer networks were finally demonstrated. Mechanical strength, modulus of elasticity, hardness, and impact resistance were discussed. The issue of the relationship between chemical structure and water sorption was also addressed.

“…Water Sorption and Solubility. Low interaction of dental composites with water is highly desirable to maintain physical/mechanical properties, 62 increase the chemical stability, 63 and minimize leaching of the low-molecular-weight species into the oral environment. Different procedures have been employed to evaluate the water sorption (WS) and water solubility (WSl) of dental composite materials and their resin matrix.…”

Dental composites are becoming increasingly popular in esthetic restorative dentistry and present a promising substitute for amalgam. However, the major hurdles that hinder their total adoption in restorative dentistry are limited longevity and possible health risks, leading to significant attempts for addressing these shortcomings. Besides the new materials, the evaluation methods play a critical role in the introduction and improvement of these types of materials. This review aims to cover the characterization methods in the evaluation of dental composites that are most employed nowadays. Therefore, the methods for evaluating the physical properties of the dental composites are first explained. Subsequently, the assessment methods of curing kinetics and the mechanical properties of the composites are classified and reviewed. Afterward, the article delves into the introduction and classification of the microscopic and antibacterial evaluation methods. Finally, the test methods for assessment of in vitro cytotoxicity and self-healing ability are described. It should be noted, for each test method, the most recent and interesting articles are cited. It is envisaged that this review will facilitate an understanding and provide knowledge for the section and utilizing the most effective and suitable characterization methods for future research on the development of dental composites.

With the aim of reducing human exposure to Bisphenol A (BPA) derivatives in dentistry, a fluorinated dimethacrylate monomer was synthesized to replace 2,2-bis[4-(2-hydroxy-3-methacryloy-loxypropyl)-phenyl]propane (Bis-GMA) as the base monomer of dental resin. After mixing with reactive diluent triethyleneglycol dimethacrylate (TEGDMA), fluorinated dimethacrylate (FDMA)/TEGDMA was prepared and compared with Bis-GMA/TEGDMA in physicochemical properties, such as double bond conversion (DC), volumetric shrinkage (VS), water sorption (WS) and solubility (WSL), flexural strength (FS) and modulus (FM). The results showed that, when compared with Bis-GMA based resin, FDMA-based resin had several advantages, such as higher DC, lower VS, lower WS, and higher FS after water immersion. All of these revealed that FDMA had potential to be used as a substitute for Bis-GMA. Of course, many more studies, such as biocompatibility testing, should be undertaken to prove whether FDMA could be applied in clinic.
