Abstract

In vivo plaque formation was significantly reduced when tooth surfaces were subjected to topical iodine (0.2% I1⁄2 in 2.4% KI) twice daily for three days. Similarly, in vivo plaque formation was significantly reduced on enamel surfaces that had been subjected to ultraviolet irradiation. Control experiments indicated that the plaque inhibitory action of irradiation resided with its interference with bacterial cell division. The results are interpreted to suggest that plaque grows in mass primarily by the division and multiplication in situ by plaque bacteria, not by a continued apposition of salivary microbes.
