The adherence of 4 strains of oral bacteria to hydroxyapatite and to chemically modified hydroxyapatite was investigated in vitro. It was found that successive treatment of hydroxyapatite beads with potassium phytate and hexadecylamine lead to complete inhibition of the adherence of three Gram-positive strains, Streptococcus mutans, Streptococcus sanguis and Actinomyces viscosus, but not of the Gram-negative Fusobacterium strain. Coating of the hydroxyapatite surface with saliva prior to treatment with phytate and amine did not significantly change bacterial adherence. When phytate and amine-treated hydroxyapatite was post-treated with saliva, the adherence of S. mutans and A. viscosus, but not of S. sanguis, was still completely blocked.
