Fluorine,PSM,COMMUNITY MEDICINE,DR NARENDRA KUMAR YADAV

Fluorine is a micronutrient mineral found in bones and teeth that is essential for bone and dental enamel formation. It is obtained mainly from drinking water as well as foods like seafood, cheese, and tea. Fluorine intake is beneficial up to certain levels but can cause dental or skeletal fluorosis in excess. The recommended level of fluoride in drinking water is 0.5-0.8 mg/L and over 1.5 mg/L can cause dental fluorosis visible on front teeth. Intake of 3.0-6.0 mg/L may lead to skeletal fluorosis while over 10 mg/L can result in crippling fluorosis.

Systemic fluoride dr.huda

huda1234567890

Systemic fluoride was used as early as 1874 to prevent dental caries. Fluoride ions are absorbed in the gut and nearly all retained fluoride is incorporated into developing bones and teeth, making enamel crystals larger and more stable. This affects crown morphology by making pits and fissures shallower, less likely to cause decay. Systemic fluoride intake can cause dental fluorosis if intake is too high during tooth development between ages 1-4. Topical fluoride is now recognized as more important for caries prevention than systemic fluoride.

Fluorosis in India - Prevention and Control

Akash Dass

Fluorosis is a disease caused by the consumption of excessive amounts of mineral fluorine for long periods. In India, approximately 25 million people are presently affected by fluorosis and 66 million are at risk of developing fluorosis, including children of age 14 years. India is situated in the geographical fluoride belt and in areas where fluoride content is high in rocks or soil, leaching of fluoride occurs, causing excess fluoride levels in groundwater.

D.p.h. 09

This document provides information on the prevention of dental caries through the use of fluoride. It discusses that fluoride can be used systemically by ingesting it or topically by direct application. Fluoride works to prevent dental caries by strengthening enamel, inhibiting bacteria, and enhancing remineralization. Sources of fluoride include water, foods, dental products, and professional treatments. Both optimal levels and methods of delivery are covered.

Fluoride

Dr.Rahul Tiwari

Fluorides are minerals that help strengthen tooth enamel and prevent cavities. Fluoride works by changing the crystalline structure of enamel to make it less soluble and by inhibiting cariogenic bacteria. It is incorporated into tooth mineral during development and remineralization to make the enamel less soluble. Sources of fluoride include drinking water, dental products like toothpaste and mouthwashes, and dietary supplements. Excessive fluoride intake can lead to dental or skeletal fluorosis. Maintaining proper nutrition supports oral health by promoting integrity of oral tissues, maintaining calcified tissues, and supporting the immune response.

Fluoride is a trace element found naturally in water sources and soils. It is beneficial for dental health when consumed in optimal amounts. Fluoride strengthens tooth enamel and promotes remineralization. It is most effectively delivered through community water fluoridation but can also be obtained through foods, supplements, and topical treatments like toothpaste. Both low and high fluoride intake can pose health risks like dental fluorosis. Careful monitoring of intake levels is important, especially for young children, to maximize dental benefits and avoid risks.

Fluorides

pallavi1211

Fluoride helps prevent tooth decay through several mechanisms. It inhibits demineralization, promotes remineralization, alters the action of plaque bacteria, and improves enamel crystallinity and reduces solubility. Both pre-eruptive and post-eruptive exposure to fluoride provides caries prevention benefits, with maximal effects seen from high exposure both before and after tooth eruption. Community water fluoridation was first introduced in the 1940s and has been shown to reduce tooth decay rates by 40-59% in both primary and permanent teeth.

Salt fortification involves adding micronutrients like iodine and iron to common salt to prevent deficiencies. Iodized salt contains added iodine to prevent goiter, with production levels at 30 ppm and consumer levels at 15 ppm. Double fortified salt contains both iodine and iron to prevent goiter and iron deficiency anemia. It provides 40 mcg of iodine and 1 mg of iron per gram of salt. While salt fortification helps prevent deficiencies, iodization can potentially cause issues like thyrotoxicosis and Hashimoto's disease.
