Incorporation of nanoparticles into the thermal behavior of polycarbonate resin: A systematic review

Background: Nanoparticles are used for preventing oral diseases, fabricating prostheses, and for dental implantation. They are also used for delivering drugs for oral application, preventing and treating oral diseases, includeing oral cancer, and maintaining the health of oral tissues to a greater extent.

Purpose: To systemically analyze the thermal behavior of nanoparticles-incorporated polycarbonate resin.

Materials and Methods. Online databases like Google Scholar, PubMed, PubMed Central, Scopus, Cochrane, and Science Direct were searched using the key terms polycarbonate resin OR nanoparticles, polycarbonate resin AND nanoparticles, and polycarbonate resin NOT nanoparticles from 1^st January 2010 to 31 ^st December 2024. The inclusion criteria were in vitro studies with full-text articles in the English language, and the exclusion criteria were clinical research, randomized clinical trials, animal studies, articles with only abstracts available, and literature reviews.

Results. After applying the inclusion and exclusion criteria, 22 original articles were thoroughly analyzed, and 11 studies were selected for a systematic review. Thermal properties like glass transition temperature and decomposition of polycarbonate and nanoparticle composites were affected by nanoparticles such as Silica, Titanium, Zinc, and Zirconium at various percentages.

Conclusion. Thermal properties like glass transition temperature, light transmission, and decomposition rate decreased, while the storage modulus and flame retardancy increased with the increasing percentage of Silica, Titanium, Zinc, and Zirconium nanoparticles.
