Aim: The aim of the present study was to investigate the effect of a 3-month strict oral hygiene phase on key parameters of periodontitis: plaque, bleeding on probing (BOP) and probing pocket depth (PPD).
Materials and methods: Forty-four patients with severe periodontal disease were randomly allocated to a test or a control group. The test group completed a 3-month strict oral hygiene phase. The control group did not receive any instructions or motivation on oral hygiene until after the 3-month period. Plaque, BOP and PPDs were registered on four sites of each tooth at baseline and after 3 months in both groups, as well as after the postponed hygiene phase in the control group.
Results: A statistically significant and profound reduction in plaque, BOP and PPD was observed after the 3 months in the test group. No change to the better occurred in the control group.
Conclusion: A 3-month strict oral hygiene phase in patients referred for periodontal therapy reduced plaque, BOP and pocket depth to such an extent that it could affect therapy planning.
Trial registration: ClinicalTrials.gov NCT01318928.
