In restorative dentistry, nanomaterials are widely used in constructing nanocomposite resins, bonding agents, endodontic sealants, coating materials, and bioceramics. They are also used for making daily dental hygiene products such as mouth rinses. The present article classifies nanostructures and nanocarriers in addition to reviewing their design and applications for bone and dental regeneration.The recent emergence of novel, pathogenic COVID-19 disease associated with SARS-CoV-2 virus in China and its rapid national and international spread pose a global health emergency. The development of a new drug is tedious and may take decades to develop and involves multiple steps like development of prototypes and phase I to III human trials which involve the study on small to large populations to examine the safety and side effects associated with drug under trials. Due to continue increasing the confirmed cases and deaths, there is an urgent need to develop a drug that is effective to kill SARS-CoV-2 virus with fewer side effects to human body. Therefore, this review focus on the latest advances in the development for the treatment of COVID-19 disease associated with SARS-CoV-2 with repositioning of already marketed drug with small molecules, as well as Chinese traditional medicines with established safety and efficacy which are being used for different therapeutic uses.A amyloid-β (Aβ) plaque formation in the brain is known to be the root cause of Alzheimer's disease (AD), which affects the behavior, memory, and cognitive ability in humans. The brain starts undergoing changes several years before the actual appearance of the symptoms. Nanotechnology could prove to be an alternative strategy for treating the disease effectively. It encompasses the diagnosis as well as the ther
