The activity of periodontal disease was determined through the collection of the gingival bleeding index (IS) Ainamo & Bay and the visible plaque index (IPV) Silness and Löe and performed the beginning of the research (T0), with 15 days (T15), 30 days (T30) and 60 days (T60). Results: G1 was more efficient in the period of 15 days and 30 days than G2 and G3. Conclusion: The use of a single dose of chlorhexidine included in beta-cyclodextrin Cx: β-Cd gel is effective in reducing clinical signs of gingivitis in patients with orthodontic appliances.
