Effect of toothbrushing with different concentrations of chlorhexidine on the development of dental plaque and gingivitis.

This study showed that 0.15, 0.10, and 0.05% chlorhexidine gluconate solutions used on the toothbrush subsequent to scaling were for at least 45 days able to maintain plaque and gingivitis scores lower than those obtained 14 days after scaling and oral hygiene instruction. Discoloration of teeth and fillings were the only side effects observed.
