Manual orthodontic vs. oscillating-rotating electric toothbrush in orthodontic patients: a randomised clinical trial

Authors:

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. MATERIALS AND

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.
