Early diagnosis of the caries lesion is important because the carious process can be modified by preventive treatment so that the lesion does not progress. If the caries can be diagnosed at an initial stage (e.g., white spot lesion) the balance can be tipped in favor of arrestment of the process by modifying diet, improving plaque control, and appropriate use of fluoride. Early detection and prompt treatment is the tenet of secondary prevention and it should be done whenever primary prevention is not totally effective Using non-invasive quantitative diagnostic methods, it should be possible to detect lesions at an initial stage and subsequently monitor lesion changes over time during which preventive measures could be introduced.For this reason, the search is on for more specific and sensitive tools, using new technologies, to help the practitioner diagnose initial canes lesions as precisely as possible.

Fluorine is an element, the 9th in the periodic table. Fluoride is a naturally occurring compound that can help prevent dental decay. The fluoride ion comes from the element fluorine .Fluorine is an abundant element in the earth¿s crust in the form of the fluoride ion. Systemic fluoride is ingested through water, salt, sugar and milk supplies or tablets, dietary or food supplementation Water fluoridation is defined as controlled upward adjustment of the concentration of fluoride in the community water supply so as to achieve maximum caries reduction at 1ppm of fluoride and clinically insignificance level of fluorosis. Salt fluoridation is the controlled addition of fluoride, usually sodium and potassium fluoride, during the manufacture of salt for human consumption. Fluoridation of salt is a best alternative method to community water fluoridation for prevention of dental caries in a mass scale.Milk fluoridation is the addition of a measured quantity of fluoride to bottled or packaged milk to be drunk by children. Milk is an essential compound of the human diet throughout the life, both as a source of micro-nutrients and macro-nutrients.

This book addresses the different problems, practices, challenges and opportunities in sustainable resource management with the help of decision-making techniques to showcase the relevance of computational modelling approaches in sustainable management and Industry 4.0. It aims to address the inherent complexity of managing ecosystems, particularly with respect to involvement of multi-stakeholders, lack of information and uncertainties. Critical analyses are made to point out the need for, and propose a call to, a new way of thinking about sustainable resource management. This book will be useful for academicians, researchers, and industrialists in the field of industrial and production engineering.
