| dc.description.abstract | Background : Root canal treatment aims to eliminate bacterial infections within the
root canal system and prevent reinfection. The ideal filling material should have
antimicrobial properties, good dentinal tubule penetration, and prevent microleakage.
Chitosan and propolis are natural materials with high potential in medical
applications, including as endodontic sealers, due to their antimicrobial,
biocompatibility, and adhesion properties. The combination of chitosan-propolis
nanoparticles in endodontic sealers can enhance sealing ability and mechanical
properties.Objective : This study aims to compare the chemical and mechanical
characteristics of nanoparticle-based chitosan-propolis sealers (nCOS-P) with
commercial bioceramic sealers.Methods : This experimental laboratory study tested
the material characteristics using X-Ray Diffraction (XRD), Scanning Electron
Microscope – Energy Dispersive X-ray (SEM-EDX), and mechanical properties tests
such as setting time, flow, and film thickness. Samples used were nanoparticle chitosanpropolis-
based sealers and commercial bioceramic sealers.Results : The results
showed that the nCOS-P sealers had diffraction peaks and element compositions
comparable to bioceramic sealers, as well as faster setting times, better flowability,
and thinner film thickness compared to commercial bioceramic sealers. Conclusion :
The nCOS-P sealers demonstrated good potential as an alternative root canal sealer
with superior physical and chemical properties compared to commercial bioceramic
sealers. The combination of chitosan and propolis offers advantages in terms of
penetration, sealing ability, and biocompatibility. | en_US |
