COVID-19 mainly spreads through cough or sneeze droplets produced by an infected person. The viral particles are mostly present in the oral cavity. The risk of contracting COVID-19 is high in the dental profession due to the nature of procedures involved that produce aerosols. Along with other measures to limit the risk of infection, pre-procedural mouth rinses are beneficial in reducing the viral particles in the oral cavity. In this study, the antiviral efficacy of essential oil components has been determined specifically against SARS-CoV-2 by molecular docking and conceptual DFT approach. Based on the binding affinities of the components against the receptor binding domain of the S1 glycoprotein, cuminal, carvacrol, myrtanol, and pinocarveol were found to be highly active. The molecular descriptor values obtained through conceptual DFT also indicated the above-mentioned components to be active based on the correlation between the structure and the activity of the compounds. Therefore, pre-procedural mouth rinses with these components included may be specifically suitable for dental procedures during the COVID-19 period.
Nanotechnology is of intense interest to researchers due to the basic fact that the properties of the material can be effectively manipulated when the size is transformed to nanoscopic. New opportunities arise out of the unique features which have been effectually utilized in the development of nano pharmaceuticals. This has revolutionized the health care system extensively by its diverse applications in modern medicine and dental science. Material science and periodontics have jointly adopted this technology to produce nanoparticles for targeted drug delivery, which find considerable significance in the management of periodontal diseases. Periodontitis is principally polymicrobial in nature, affecting the supporting structures of the tooth. In addition to the conventional mechanical debridement, adjunctive chemical therapy is, at most times, required to resolve the chronic inflammation. Hence, targeted drug delivery using nanoparticles with improved pharmacological and therapeutic properties may form better treatment strategies for managing this chronic inflammation. As nanoscale technology finds a scope in varied applications in periodontics, this current review highlights the various nanoscale drug delivery systems for managing periodontal diseases.
Periodontal diseases are highly prevalent oral conditions associated with severe complications in the oral cavity. These inflammatory diseases are caused by the oral microbiome and are influenced by several factors, such as aging, tobacco usage, systemic illness and inadequate oral hygiene. Plant-derived phytochemicals are extensively utilized in managing various periodontal diseases due to the presence of antioxidant, anti-inflammatory and antibacterial activities. Plant materials have shifted attention from conventional medicine to indigenous medicine. Solanum xanthocarpum is a medicinal herb found in India. It exhibits various pharmacological properties essential for periodontal disease prevention and management. The current work analyzes various pharmacological properties of S. xanthocarpum aqueous extract. The S. xanthocarpum extracts’ antioxidant, anti-inflammatory and anti-microbial properties were ascertained by DPPH assay, HRBC membrane stabilization assay and disk diffusion assay, respectively. S. xanthocarpum’s active phytochemical components were detected using gas chromatography–mass spectrometry (GC-MS) estimation. Furthermore, molecular docking and simulation analysis were conducted to determine the interaction between phytocompounds and the RgpB protein of Porphyromonas gingivalis. Phytocompounds possessing anti-microbial, antioxidant and anti-inflammatory properties were detected through GC-MS estimation. The molecular docking and simulation analysis revealed the inhibitory mechanisms of the phytocompounds Solasodine, Lupeol and Quercetin against arginine-specific gingipain RgpB protein. Insilico analysis revealed that Lupeol had the highest binding energy of −263.879 Kcal/mol among the phytocompounds studied, followed by Solasodine with a binding energy of −102.457 Kcal/mol and Quercetin with a binding energy of 33.6821 Kcal/mol. The study revealed that S. xanthocarpum has significant potential as an herbal remedy for preventing and treating periodontal diseases. This may facilitate drug development in the future.
