Optimal Homotopy Analysis Method (OHAM) For the Approximate Series Solution of Non-linear Partial Differential Equation
Abstract: In this article, we have used the Optimal Homotopy Analysis Method (OHAM), which is a basically semi-analytic method to solve differential equations. The ability for the user to choose the convergence control parameter, auxiliary linear operator, auxiliary function, and starting approximation is what sets apart the OHAM technique. We guaranteed the efficacy and efficiency of the procedure by fine-tuning the convergence control parameter. We solved a non-linear partial differential equation …

Oral Health wsr to Dental Fluorosis: A Review
Abstract: Dental fluorosis occurs due to the hypo mineralization of tooth enamel. This can lead to discoloration of the teeth. Mild and very mild fluorosis can cause teeth to look whiter, and therefore, it can improve esthetic perceptions of teeth, thereby leading to better OHRQoL (Oral Health related quality of Life). On the other hand, moderate and severe fluorosis can cause more noticeable tooth discoloration and, in some cases, even loss …
