Dentist.ro | 05.11.2010



Toti se intreaba daca este nevoie sa se administreze fluorul suplimentar si de ce? Fluorul formeaza fluoropolita care, in comparatie cu hidroxiopolita (in compozitia caruia intra calciu), este mai rezistenta la acizi. Prin aceasta se si explica de ce fluorul este benefic dintilor.


Beneficiile fluorului


La randul sau, fluorul participa la asimiliarea fierului, asigura cresterea unghiilor si a parului, participa la metabolizarea calciului si a fosforului, determina eliminarea metalelor grele si a radionuclizilor din organism, participa in procesele de hemostaza etc. Ca sursa de baza, fluorul il luam din apa in proportie de 60-70%,  iar restul din alimente. Cel mai bogat continut de fluor il are pestele, cu precadere cel din ocean, spre ex : in 100 gr de scrumbie se gasesc 1,7 mg de fluor, ceaiul negru la randul sau contine foarte mult fluor (ceasca de ceai contine in jur de 0,1-0, 2 mg).


Excesul de flour


Doza zilnica de fluor intr-un organism al unui om matur este de 2-3 mg. Desi face parte din dieta noastra zilnica, fluorul este unul dintre cele mai toxice elemente chimice. El intra in compozitia multor arme letale toxice. Este indispensabil in industria metalurgica, chimica, fara el nu s-ar putea realiza arma nucleara. Excesul de fluor duce la aparitia fluorozei dentare cu discromii (formarea de pete albe pana la pete maronii inchise), in cazuri mai grave ducand la distrofii grave cu pierderi de smalt. La excesul de fluor in momentul dezvoltarii, acesta duce la dereglarea formarii matricii proteice care se inlocuieste in mod normal cu cristale de hidroxid si se formeaza cristal de fluorid de calciu, care are o culoare mai inchisa.


Problemele cauzate de fluor


Intoxicarea cionica cu fluor duce la dereglarea structurii aparatului locomotor (oase, articulatii), eliminarea din organism a magneziului ce participa in asimilarea calciului, deformarea scheletului osos, exostoze osoase, dereglarea procesului metabolic al glucidelor si a lipidelor afecteaza functia glandei tiroidale si paratiroidale.

Doza optima de fluor difera de la persoana la persoana. Ea este determinata de varsta, masa corporala, sex, zona in care locuieste persoana in cauza, continutul de fluor din apa potabila si cantitatea de apa utilizata (determinata uneori de factori precum : canicula, unele patologii asociate ale pacientului etc), activitatea profesionala (daca lucreaza intr-o intreprindere metalurgica, chimica), prezenta in zona in care locuieste a uzinelor de prelucrare a metalului, alimentatia preponderent cu produse din ocean (fructe de mare, scrumbie, alte specii de peste oceanic).

Concluzionand, fluorul in doze mici este un element de protectie pentru organism, in doze mari el putand fi considerat un dusman de temut (otrava). De aceea este absolut indispensabila o consultatie in prealabil la un medic specialist.
