These studies on remineralization of dental calculus matrixes indicated that above a Ca x P (mg./100 ml.)2 of 35, remineralization occurred whether or not CO2 were present under optimal conditions. Below 35 (mg./100 ml.)2, induction required CO2.
Sodium incorporation into K solutions at high ionic strengths (0.165) enhanced remineralization. A temperature of 37.5° C. was slightly more effective than 25° C. when the pH was decreased.
Remineralization at 756 mm. of Hg was nodular in and on the matrix. The nodule consisted of needle-like radiopaque crystals radiating from a center. At 190 mm. of Hg, remineralization was throughout the whole matrix with myriads of interconnected, small, round radiopaque areas.
