Uses of fluorides

hi venus this is dr srikanth from team mds conquer now i'll be talking about the advantages of fluoride reacting with dental structures so most of the dental structures they contain a molecule which is called as hydroxyapatite when this hydroxyapatite reacts with the fluoride it forms two molecules one is fluoro hydroxyapatite and fluorepetite when you compare the critical ph of these two i hope you know what is the meaning of critical ph critical ph is a ph around which demineralization and remineralization takes place whenever the critical ph is below this 5.2 to 5.5 there will be demineralization whenever it is above it will be remineralized i hope you know this concept so when you compare the critical ph of normal teeth it is 5.2 to point five whereas fluorapatite or hydroxyl fluoride is four point two to four point five which clearly gives the meaning that more acid is required for dissolution of a teeth when it reacts with the fluoride so it is more acid resistance when compared with the normal depth and it is more in size you can see there is increasing in size here when i compare with the normal t there will be increasing in size and there will be decreasing in the critical page so taking these advantages into consideration okay fluoro hydroxyapatite or fluoropathetic requires more acid to dissolution are increasing in size and all these are advantages which make tough for the bacteria to dissolve or tough for the acid to dissolve okay i'm done with this particular concept signing off dr srikanth from team mds conquer take care
