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 …
