To study the antifungal activity of ZnO nanoparticles synthesised from amla fruit. Nanotechnology has offered great possibilities in various fields of science and technology. It has been playing a crucial role in the development of modern materials in recent years. The antifungal activity of ZnO occurs by the deformation of fungal hyphae leading to the death of fungal hyphae, which may lead to cellular destruction. Preparation of plant extract, Synthesis of nanoparticles, Characteristics of nanoparticles, Preparation of nanoparticles powder, Antifungal activity of nanoparticles against Candida albicans.The peak found in the spectroscopy indicates the formation of ZnO nanoparticle. It is clearly seen from the graph that increase in concentration results in an increase in antifungal activity. The antifungal activity, in this case, was proved with Aspergillus niger and Aspergillus terreus. The results conclude that ZnO nanoparticle can be used to prevent any antifungal diseases.

Complete removal of the infected coronal and radicular pulp tissue along with obturation of the canal space with suitable medication is defined as pulpectomy. The most common indication for pulpectomy is a tooth with irreversible pulpitis which shows symptoms of nocturnal pain and abscess. To determine the average time in appointments for multivisit pulpectomy in patients reported to a university dental hospital. It is planned as a retrospective analysis of the case records of patients who were treated as two visit pulpectomy procedures in a university dental hospital, India. The study concluded that in the majority of the situations the average time in between appointments for multivisit pulpectomy was found to be within 1 week.

Aim: The present study aimed to analyse the cytotoxicity of zinc oxide nanoparticles (ZnO NPs) that are biosynthesized using extract of Abies webbiana Methodology: Zinc oxide nanoparticles were synthesized by green approach using A. webbiana and were characterized by UV- vis spectroscopy. The powdered A. webbiana mediated ZnO NPs were subjected to cytotoxic tests for different concentrations by brine shrimp lethality assay. Results: ZnO NPs synthesized from A. webbiana showed reduced toxicity at lower concentrations. After 48 hours, it was found that at a minimal concentration of 5 µl, 90% of the nauplii and in concentration of 10 µl and 20 µl, 80% of the nauplii were alive. At a concentration of 40 µl and 80 µl, 70% of the nauplii were alive. Whereas the control showed 100% of the nauplii to be alive. Conclusion: Various nanoformulations of A. webbiana mediated ZnO NPs can be developed at optimal concentrations for therapeutics that are safe and economical.
