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 …

Intelligent Gear Inspection: Defect Detection through Digital Image Processing Algorithms
Abstract: A significant contributor to poor reliability and a source of humiliation for businesses are gear problems. The majority of the inspection procedures used in these businesses are laborious and manually. More thorough and accurate inspection procedures are needed to improve accuracy in finding gear problems. The present work fills this gap by implementing a Gear Defect Recognizer that uses local thresholding in conjunction with computer vision methodology to spot potential …

Effectiveness of Planned Teaching Programme on Knowledge Regarding Dental Fluorosis
Abstract: Introduction: Dental fluorosis remains one of the most common disorders affecting the teeth, starting right from the early age. Hence it is important to prevent dental fluorosis from the school age level. To a certain duration (as per WHO; 0.6 ppm), fluoride ingestion is useful for teeth and bone development, but excessive ingestion causes a disease called fluorosis. The greatest matter in dental fluorosis is aesthetic modification in the permanent …

Analytical Modeling and Simulation of Helical Gear Systems for Improved Load Distribution
Abstract: An analytical modeling and simulation methodology to improving load distribution in helical gear systems is presented in this research study. Fundamental parts of many mechanical systems, helical gears provide the benefits of smooth engagement, lower noise levels, and increased weight bearing capability. However, retaining lifespan and dependability in gear systems requires establishing regular load distribution throughout the gear teeth. This work explores the parameters influencing load distribution and suggests strategies …

Fluoride Distribution and Related Health Problems
Abstract: Fluoride is one of the very few chemicals that cause significant effects in people depending upon their concentration. Although present naturally in soil, water and air, fluoride consumption occurs largely through water. Fluoride intake at low concentration is known to cause beneficial effects on teeth, however at high concentrations; it may give rise to a number of adverse effects. These range from mild dental fluorosis to crippling skeletal fluorosis as …

Dynamic Analysis of a Multi-geared Rotor Shaft System
Abstract: Gear systems are the toothed members in which the main aim is to transmit power or motion between two shafts by meshing without any slip. Motion and power transmitted between the shafts are kinematically equivalent to power or motion transmitted between frictional wheels. Vibration of gear system causes unwanted noise such as gear whirling. Noise and vibration signals from machine can contain vital information about the internal processes and provide …
