This research using Scanning Electron Microscopy\/ Energy Disperse X-Ray (SEM\/ EDX)and Powder X-ray Diffraction (XRD). The results of this study have demonstrated Fluor concentration were higher in fluorosis enamel and the surface increasingly roughness and porous. The a-axis on fluorosis-affected enamel 9.3786 ¿, and the c-axis 6.8836 ¿. The a-axis on normal enamel 9.4148 ¿, and the c-axis 6.8791¿. The grain size of fluorosis-affected enamel 19.59 nm and normal enamel 20.30 nm. The microstrain of fluorosis-affected enamel 31.54% and normal enamel was 20%. This study concluded that Fluor, as a mostly electronegative element, decreases the crystallinity and improves the microstrain of hydroxyapatite. These conditions will influence the strength and stability of fluorosis-affected enamel.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659244759\"\u003e\u003ch3\u003eStudy of Dental Sciences Base\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659244759","offer_id":39439912075357,"sku":"9783659244759","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6f4f48b5-9e67-4f1f-bcd5-d90ddaad2650.jpg?v=1776493492","url":"https:\/\/shop.autorenwelt.de\/products\/nanostructure-of-crystal-hydroxyapatite-from-fluorosis-affected-enamel-study-of-dental-sciences-base-von-abdillah-imron-nasution","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
