The surface roughness difference between microhybrid and polycrystalline composites after polishing

Comparative evaluation of three nanofilled resin-based dental composites: Cytotoxicity, surface roughness, and flexural properties

“…It is claimed that this resin composite has high flexural properties, biocompatibility, and smooth surface after polishing, resulting in excellent esthetics. 10…”

“…It is claimed that this resin composite has high flexural properties, biocompatibility, and smooth surface after polishing, resulting in excellent esthetics. 10 Since nanocomposites are widely used in anterior restoration, their surface properties, polishability, and surface roughness are always a concern. High surface roughness affects the esthetics, result in discoloration, susceptibility of the restoration to plaque accumulation, and impact the restoration longevity.…”

“…Although there have been some researches on nanohybrid and nanoceramic resin composites’ surface properties, there is a lack of information regarding these materials' performance in regard to their cytotoxicity and flexural properties which make the investigation of their mechanical and biological properties necessary. 10,14 Especially, Weibull modulus, which determines the reliability of restoration, has not been previously evaluated in nanocomposites. The novelty of our study was evaluation and comparison of these properties which is a unique and new approach in dental nanocomposites evaluation.…”

Anterior makeover on fractured teeth by simple composite resin restoration

“…This is also supported by improvements in adhesive technology through various bonding generations and equipment such as polishing instruments and LED curing units for faster polymerization. [1][2][3] In daily practice dentists usually treat tooth fractures with more invasive treatments such as crown, veneer and bridges which preparation require more tooth structure removal. While currently there is trend toward minimal invasive dentistry which conserves more tooth structure.…”
