Abstract: Aim To compare the efficacy of manual and oscillating-rotating electric toothbrushes in removing plaque and reducing gingivitis in patients with fixed orthodontic appliances.
Study design Randomised clinical trial.
Methods 20 subjects aged 10 to 14 years (8 males; 12 females) scheduled for fixed orthodontic treatment were enrolled, randomly divided into two groups, A and B, and later assigned electric or manual toothbrushes, respectively. Three months after orthodontic appliance bonding (T1), and again after a further 4 (T2) and 8 (T3) weeks, plaque levels (PI), gingival bleeding (GBI) and hypertrophy were assessed. Results Between the two toothbrush types, statistically significant differences in PI were detected from T2 to T3 (P value=0.010), but not from T1 to T2. In contrast, the GBI was significantly different from T1 to T2 (P value=0.025), but not from T2 to T3.
Conclusion With respect to the manual orthodontic toothbrush, the electric oscillating-rotating toothbrush was found to better improve both PI and GBI.
