Abstract

Patients with fixed orthodontic appliances frequently have increased levels of plaque accumulation leading to the possibility of gingivitis or enamel decalcification. Although many methods may be helpful in reducing dental plaque formation, optimal mechanical removal of plaque is tile most important factor during orthodontic treatment.
The porpose of this study was to evaluate the efficacy of´an electric toothbrush, with a specially designed orthodontic brush head. compared with a manual toothbrush in controlling plaque and gingivitis for patients with fixed orthodontic appliances. Oral hygiene status was measured in thirty four patients, using a plaquc index, a gingival index and a bleeding index. before and four weeks after attachment of fixed orthodontic appliances. Patients were randomly divided into two groups, the electric and the manual toothbrush groups. Oral hygiene instruction was given according to the type of toothbrush used. The Braun Oral-B D9511 with Braun Oral-B Ortho OD 15-1 brush head was used as the electric toothbrush while the Butler G.U. M 124 was given as the manual toothbrush. After 4 weeks and 8 weeks, oral hygiene status was measured again. Through the comparison berween the electric and the manual toothbrush grpups. following results were obtained.
1. All oral hygiene indices showed increasing tendency after 4weeks of fixed orthodontic appliances.
2. All indices presented decreasing tendency four and eight weeks after oral hygiene instruction.
3. In case of gingival index and bleeding index. decreasing tendency did not show a statistically significant difference between the electric and the manual toothbrush groups.
4. The decreasing tendency of plaque index presented statistically significant difference between the two groups. showing that the electric toothbrush was more effective in terms of oral hygiene.
These findings suggest that an electric toothbrush is useful to the orthodontic patients with fixed appliances.
