RESUMEN
The aim of the present study was to determine the concentration of total fluoride (TF) and total soluble fluoride (TSF) in children's dentifrices marketed in the city of Lima, Peru. Three samples of 23 dentifrices (4 without fluoride and 19 with fluoride) were purchased in different pharmacies in Lima, Peru. The TF and TSF concentrations found in the dentifrices were determined by ion-selective electrode, expressed in ppm F (µg F/g of dentifrice). The TF concentration in the majority of the fluoride toothpastes matched that shown on the label, except for one declared as 1450 ppm F by the manufacturer, whereas only 515.1 ppm F was found. The concentration of TSF found in the fluoride toothpastes ranged from 457.5 to 1134.8 ppm F. All the dentifrices were formulated with silica, but one also presented calcium carbonate. In conclusion, 83% of the children's dentifrices marketed in Lima, Peru, were fluoridated, but only 53% contained a TSF concentration greater than 1000 ppm F, the minimum concentration required to provide an anticaries effect.

La pasta pulidora kleener no requiere de preparación previa aplicándosela directamente del envase - La técnica no requiere aparatologia especial para la obtención del pulido de cualquier restauración dental, pudiendo realizarse en forma manual.Resulta, en concecuencia de facil manipulación - No tiene acción nociva sobre las mucosas de la boca. Asi mismo los fluidos bucales no acatan superficies pulidas con la pasta Kleener, permaneciendo éstas inalterables - Es el material más indicado para aquellos lugares donde se carece de corriente eléctrica por no precisarce en dicha fuente y ser posible un trabajo puramente manual
