Nanotechnology-Enabled Non-Invasive Teeth Whitening: Safety, Efficacy, and Regulatory Perspectives with a Focus on India, Asia, and Developed Countries
Abstract: Demand for tooth whitening is growing worldwide, but conventional peroxide-based bleaching is associated with dentin hypersensitivity, enamel softening, and soft tissue irritation, especially under repeated or high-concentration use. Nanotechnology offers a new class of non-invasive whitening strategies that aim to combine esthetic improvement with enamel protection and remineralization. Among these, nanohydroxyapatite (nanoHAP) toothpastes and gels have the most advanced evidence base; in vitro and in situ studies indicate that nanoHAP …

Effect of Bacillus Subtilis on Corrosion of Steel in Reinforced Cement Concrete
Abstract: Abstract Concrete is one of the most used building materials due to its cost- effectiveness, ease of availability, and versatility. It is the backbone of modern construction, being widely applied in infrastructure, residential, and commercial projects. However, it is particularly vulnerable to crack formation, which significantly reduces its service life. These cracks compromise structural integrity by allowing water ingress, which leads to the corrosion of reinforcing steel, eventually making the …
