Small RCT comparing mouthwashing with PVP-I, Chlorhexidine, and water, showing significant efficacy for both PVP-I and Chlorhexidine, with PVP-I increasing Ct by a mean of 4.45 (p < 0.0001) and Chlorhexidine by a mean of 5.69 (p < 0.0001), compared to no significant difference for water.
inverse relative improvement in Ct value, 88.8% lower, RR 0.11, p < 0.05, treatment 25, control 9.
