Özet:
98 SUMMARY The purpose of this study, is to determine the effects of fluorides and trace elements applied alone or in combination at different concentrations on the solubilities of enamel and cementum surfaces of the same teeth. The study has been performed on enamel and cementum surfaces of the impacted third molars extracted by surgical operation. Aqueous solutions of sodium fluoride,aluminum potassium phosphate,strontium chloride and titanium tetrachloride at different concentrations were applied on the surfaces prepared by window technique. Following such treatments,two successive acid etchings of surfaces were made. The solubilities of enamel and cementum and depths of etchings have been calculated by using the values obtained from the determination of the inorganic phosphorus in these etching solutions. According to the results, higher concentration of fluoride and lower concentrations of strontium and titanium led to significant reduction in solubilities of enamel and cementum. As some of the combined applications of fluorides and trace elements decreased both of the enamel and cementum solubilities,it may be assumed that if such a treatment is beneficial in the adolescence of an individual,it may also be used in his elderly stage.97 mine hemde sementte çözünmeyi azaltmada başarılıdır. İz elementlerin, fluorürlerle birlikte ikili ve üçlü uygulamaları genellikle başarılı sonuçlar verdiği için,kişilerin gençlik ve yaşlılık yıllarında kulanılabileceği sonucuna varılmıştır.
