“…The water uptake of the experimental formulations with and without EgMA showed values that were in agreement with previous data on commercial composite core formulations [33,34] and fulfilled the requirements for dental applications in accordance to ISO 4090 standard requirements that limit the values of water sorption and solubility to a maximum of 40 µg/mm 3 and 7.5 µg/mm 3 respectively. The reduction in water sorption and diffusion coefficients values with increasing content of EgMA monomer was due to monomer hydrophobicity and ability to form slightly cross linked structures [35] which reduced the water permeability of the polymer by decreasing the free space and thereby the swelling of the polymer.…”

AbstractObjectives: Eugenol has been used in dentistry due to its ability to inhibit the growth of a range of microorganisms, including facultative anaerobes commonly isolated from infected root canals. The aim of this study was to evaluate the antibacterial activity of the experimental composites containing eugenyl methacrylate monomer (EgMA), a polymeric derivative of eugenol, against a range of oral bacteria, commonly associated with failure of coronal and endodontic restorations. In vitro composite behaviour and wettability were also studied in conjunction with their antibacterial activity.

Introduction: Due to its chemical, mechanical and biological properties, the glass ionomer cements (GIC) consist in one of the most versatile direct restorative materials, with many potential clinical indications, especially in the context of minimally invasive dentistry. Nevertheless, they have some limitations and require the knowledge of their characteristics and procedures of application in order to achieve their maximum potential. Objective: To demonstrate through literature review the main characteristics, indications, limitations and future perspectives for the use of GIC. Literature review: The database, such as Pubmed and Lilacs were used. Additionally, books were also evaluated and included. Conclusion: The GIC is in constant evolution and is one of the materials that are best suited in the context of preventive and conservative dentistry. It has satisfactory properties and versatility. On the other hand, presents inferior properties when compared to other direct restorative materials, requiring caution during its handling.

“…The interaction of composite resin with water leads to water uptake into the composite resin through a diffusion process. Water permeates the resin network due to its porosity and intermolecular spaces and this is intensified by the hydrophilicity of the resin matrix and the composition of the resin and the contents of the fillers 1 . The water sorption followed by the solubility of resin components from the restorative material are precursors to a variety of chemical and physical degradation processes 2 .…”

AbstractIntroduction: Composite resins are subject to challenges in the oral cavity that are related to patients' habits, which can compromise the restorations' integrity and longevity. Therefore, it is necessary to study how consuming beverages and smoking cigarettes affects professional prophylaxis. Objective: The aim of this study was to evaluate how the sodium bicarbonate air-polishing affects the mass change (sorption and solubility) of a composite resin exposed to cigarette smoke, red wine, or coffee solution. Material and method: Eighty composite resin samples (FiltekZ350 XT -3M/ESPE) were prepared and distributed into 8 groups (n=10): G1 (air-polishing + distilled water), G2 (air-polishing + coffee), G3 (air-polishing + red wine), G4 (air-polishing + cigarette smoke), G5 (distilled water), G6 (coffee), G7 (red wine), or G8 (cigarette smoke). The composite resin samples were weighed in triplicate to obtain M1 (initial mass), M2 (mass after 30 days of storage in the tested solutions), and M3 (after desiccation) values. The sorption and solubility values were calculated and analyzed using 2-way ANOVA and Tukey's test (5%). Result: The experimental groups had higher sorption and solubility values than the control groups, regardless of whether air-polishing was used. There was no statistically significant difference in the sorption between the air-polished and non-air-polished groups; however, the solubility was higher in the air-polished groups. Conclusion: Air-polishing using sodium bicarbonate powder was able to intensify the solubility process of the tested resins but did not significantly increase the sorption values.
