Nanosilver from Mangosteen Peel Extract (Garcinia mangostana L.) for Antibacterial Dental Preventive Agents

Teeth are vital structures prone to issues such as caries and plaque formation, often caused by Streptococcus mutans (S. mutans). This issue can be mitigated using natural ingredients like mangosteen fruit (Garcinia mangostana L.), especially its peel, is known for its medicinal benefits. However, its extract may take time to show effects, so it is being combined with nanosilver for improved drug distribution. To observe the antibacterial and antibiofilm potential of Mangosteen Peel Extract (MPE) in nanosilver form as a preventive agent in dentistry.

The extraction was succeeded by a phytochemical assay and biosynthesis of MPE into Mangosteen Peel Extract Nanosilver (MPNs). Particle Size Analysis (PSA) and Transmission Electron Microscopy (TEM) were used to study this procedure. Disc diffusion tests were used to evaluate the antibacterial properties, and the Minimum Inhibition Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were also determined. Furthermore, the antibiofilm activity against S. mutans was investigated.

the phytochemical contents in MPE were flavonoids, tannins, saponins, phenols, alkaloids, triterpenoids, and terpenoids. Particle size of MPNs was 126.1 nm and the Polydispersity Index (PDI) was 0.419. The highest antibacterial concentration as inhibition zone against S. mutans was 16.37±0.38 mm and 119.37±2.16% inhibitory activity, at the highest concentration (100%) p<0.05. The percentage of biofilm inhibition against S. mutans was 27.64-105.94% which was concentration dependent.

MPNs has potential as an antibacterial and antibiofilm agent that can be used as a preventive agent in medicine.
