“…is supports the growing use of nanoparticles in dental restoration resins, where roughness is an important parameter [6,7]. Nanoparticle aggregates can be an alternative Journal of Nanotechnology option, but a chemical union needs to exist between the individual particles to improve their performance, and it is necessary to ensure a chemical bond of the aggregate to the polymeric matrix through functionalization.…”

“…Wear resistance is an important property in the performance of dental composites because lack of wear resistance will produce an excessive reduction in structure, resulting in the loss of posterior tooth support, vertical dimension of occlusion, masticatory efficiency and esthetics, as well as alterations in the functional path of masticatory movement, fatigue of masticatory muscles, and faulty tooth relationship [4]. Wear (resistance) performance of dental resin composites is affected by roughness and hardness, while roughness also influences aesthetic appearance, discoloration, plaque accumulation, the appearance of secondary caries, gum inflammation, and wear of opposing and adjacent teeth [5][6][7][8], and hardness, defined as how resistant the material is to penetration, can be used to predict wear resistance and the tendency of the material to erode the opposing tooth or material [7,9,10].…”

“…erefore, hardness is a parameter that is related to wear resistance but, due to other variables that affect it, there is not a direct relationship in all cases. In general, the literature reports that hardness increases with the quantity of filling [7,10,[14][15][16]. However, it is not necessarily the case that a larger quantity of filling causes an increase in the hardness of the material or generates an increase in wear resistance.…”

Roughness and hardness are among the most important variables in the wear (resistance) performance of dental resin composites. In this study, silica nanoparticles and nanoclusters of silica and silica-zirconia nanoparticles were evaluated for use as reinforcement agents in dental resin composites. Nanoclusters with spherical morphology were obtained from aqueous dispersions of nanoparticles by spray drying. Roughness was measured through atomic force microscopy (AFM) while nanohardness was evaluated by nanoindentation. The roughness values obtained with silica nanoparticles were lower (22.6 ± 6.6 nm) than those obtained with silica and silica-zirconia nanoclusters (138.1 ± 36.6 nm, 116.2 ± 32.2 nm, resp.), while the hardness values of all composites were similar (nanoparticles = 0.24 ± 0.01 GPa, silica nanoclusters = 0.25 ± 0.04 GPa, and silica-zirconia nanoclusters = 0.22 ± 0.02 GPa). Based on this study, it can be established that particle size is a determining factor in the roughness of the final material, while the key variable for nanohardness was the concentration of the reinforcement materials.

Toward esthetically and biomechanically reliable anterior resin composite restorations: Current clinical experiences among dental practitioners in Saudi Arabia

et al. 2023

View full text Add to dashboard Cite

Background: Esthetic anterior composite restorations are very challenging. They constitutes a main part of the clinical practice of restoring teeth with resin composites. Distinctive variations in composite material selection and technique of application in anterior teeth exist when compared to the practice of restoring posterior teeth with resin composites. In a continuation of a previous assessment of class II resin composite practice, a cross-sectional survey study was performed to determine the awareness of general dental practitioners in Saudi Arabia about resin composite restorations in anterior teeth and to provide evidence-based recommendations to improve their practice. Methods: A total of 500 dental practitioners from different provinces in Saudi Arabia were invited to participate in an online questionnaire which comprised four domains and included a total of sixteen questions addressing aspects regarding the selection of resin composites, cavity configuration, etching protocol, light-curing technique, liner application, application of poly-chromatic composite, as well as finishing and polishing procedures. Chi square testing and descriptive statistics were used to analyze the attained data. Results: From 250 respondents, the greatest participation was from the Eastern and Middle provinces of Saudi Arabia. Female dentists participated less than males. There was no general agreement between participants regarding the resin composite material or the employed technique of application in restoring anterior tooth defects. Respondents indicated that discoloration and hypersensitivity were the most common reasons for patient’s dissatisfaction with resin composites in anterior teeth. Conclusions: Dental practitioners are highly encouraged to improve their clinical practice of restoring anterior teeth using resin composites with the focus open over continuous education programs, online webinars, and workshops.
