Three‐year randomized study of manual and power toothbrush effects on pre‐existing gingival recession
Open accessAbstract
Aim: To compare long‐term effects of brushing with an oscillating–rotating power toothbrush or an ADA reference manual toothbrush on pre‐existing gingival recession. Materials and Methods: In this controlled, prospective, single‐blind, parallel‐group study, healthy subjects with pre‐existing recession were randomized and brushed with a power toothbrush (n = 55) or an ADA reference manual toothbrush (n = 54) for a 3‐year study period. Subjects were required to brush their teeth twice daily for 2 min. using a standard fluoride toothpaste. During the study, subjects were assessed for clinical attachment loss and probing pocket depths to the nearest mm at six sites per tooth by the same calibrated examiner. Gingival recession was calculated at pre‐existing sites as the difference between clinical attachment loss and probing pocket depths. Hard and soft oral tissues were examined to assess safety. Results: After 35 ± 2 months, mean gingival recession did not differ significantly between groups, but was significantly reduced from baseline (p < 0.001), from 2.35 ± 0.35 mm to 1.90 ± 0.58 mm in the power and from 2.26 ± 0.31 mm to 1.81 ± 0.66 mm in the manual group. Conclusions: Gingival recession in subjects with pre‐existing recession was significantly reduced after 3 years of brushing with either a power or manual toothbrush.

In patients with pre-existing gingival recessions, there are no differences between manual and power toothbrush groups in further recession when evaluated for 1-3 years.
“Even in patients with pre-existing gingival recessions, which are more susceptible to the development of further recessions, there were no differences between manual and power toothbrush groups when evaluated for 1-3 years.108,109”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
