Abstract : The fluoride effect is certain to increase resistance to dental caries, therefore, researchers and policymakers have consistently dental filling materials on the development of dental filling materials have the ability to release fluoride ions to the surrounding parts of the Age in order to increase its resistance to decay. One of these materials is Erston PHC, which was marketed on the basis of its ability to release fluoride ions and hydroxide ions also when the mean is acidic, which is equivalent to the center and increases the PH of the equation of the center and make it alkaline and thus increases the resistance of the Age of Decay. This research aims to measure the rate of release of ions fluoride and hydroxide in a laboratory of the filler Erston PHC to measure the launch of fluoride was prepared ten Tuahn modern divorce gaps of the fifth class was filled with a substance Alerston then stored the samples in the saliva of plant was measured by the proportion of fluoride regularly device measuring the electrical faded until the launch of the fluoride to measure the proportion of the hydroxide has been prepared ten Tuahn recent divorce has been the work of the fifth degree of the gaps were filled with a substance Alerston was measured at the start of the hydroxide ions of different degrees of acidity of saliva using a measure of acidity of the plant. The results showed that fluoride be starting at the top level in the first (24) hours and then drops to about (50%) after one week. Thereafter decreasing gradually until the departure of nearly vanishing after (8) weeks, and on the hydroxide ions did not show any effect in any sample at any degree of acidity.
