A comparison of three delivery methods of chlorhexidine in handicapped children. I. Effects on plaque, gingivitis, and toothstaining.

In handicapped groups, the maintenance of oral hygiene can be a major problem, and chemical plaque control offers many advantages. This study compared the effectiveness of chlorhexidine gluconate, delivered as a 0.2% mouthrinse, a 0.2% spray, and a 1% gel in trays, in controlling dental plaque and gingival bleeding in a group of 49 spastic children. All three delivery methods produced an improvement in plaque and gingival bleeding scores. However, the gel was significantly more effective than either the mouthwash or the spray. There was no significant difference between delivery methods in the amount of tooth staining.
