Experimental testing upon the effects of organic fluorides in the gingival inflamation prevention

U radu je prikazan mogući mehanizam dejstva fluorida u sprečavanju maturacije i toksičnog delovanja supra i subgingivalnog plaka. U toku smene zuba vršeno je četkanje sa Aminfluorid želeom na eksperimentalnoj i bez paste na kontrolnoj strani vilice kod pasa. Žljebom u gleđi je određena granica supra i subgingivalnog predela gleđi i zatim do dubine od 60 mikro m pomoću elektronske sonde ispitivan sastav Ca, P i F na udaljenost od 250 do 3000 mikro m. Utvrđeno je zadržavanje fluorida u površnim slojevim a na eksperimentalnoj strani i to supragingivalno i do 500 mikro m subgingivalno. Na kontrolnoj strani nisu zabeleženi površni depoziti fluorida. Oslobađanje jona fluora iz ovih akumulacija, najverovatnije u obliku CaF2 može da bude odgovorno za usporenu maturaciju dentalnog plaka.The possible mechanismus of Aminfluoride action in the inhibition of plaque maturation is presented in the paper. Experiment was performed on dogs during the eruption of permanente molars. Experimental side was brushed with AminflurideR gel and control without any paste during 5 weeks. The groove in the anamel representing a border between supra and subgingival surface was prepared. The enamel was investigated by means of electron probe for elements Ca, P and F. The presence of fluoride in the surface layers was determined on the experimental side supragingivali and subgingivali till the depth of 500 in the sulcus. A release of fluorides from theese deposites could be responsible for detoriation of plaque maturation and gingivitis prevention
