    Abstract:
    BACKGROUND: To evaluate the success of plaque reduction after external toothbrushing by instructed laypeople versus dental professionals using either a manual or powered toothbrush. Longitudinal, randomized, parallel-group intervention study in periodontitis patients with reduced oral hygiene quality undergoing anti-infective therapy. Patients were randomly and equally assigned to one of four groups: laypeople using a manual or powered toothbrush or dental professionals using a manual or powered toothbrush. Plaque reduction (Quigley-Hein-Index (QHI), Marginal Plaque Index (MPI)), gingivitis (papilla bleeding index), and cleaning time (seconds) were investigated. RESULTS: Thirty-nine patients participated in the study. Neither the choice of toothbrush (p = 0.399) nor the use of a dental professional (p = 0.790) had a significant influence on plaque levels achieved. However, multivariate modeling indicated statistically significant differences in the external cleaning time between brushing groups, with longer time required by laypeople (p = 0.002) and longer use of the powered toothbrush (p = 0.024). CONCLUSION: When the ability to carry out personal oral hygiene is reduced, external brushing by dental professionals or instructed laypeople who meet previously defined criteria such as sufficient personal oral hygiene at home could help to fill the emerging dental care gap. A combination of oral hygiene approaches adapted to the individual needs of the patients in need of external help is necessary for optimum oral hygiene.
