Powertoothbrushing for Treating Gingivitis

Not Applicable

Completed

• Conditions: Gingivitis
• Interventions: Device: Oscillating rotating power toothbrush

• Registration Number: NCT03381339
• Lead Sponsor: Marquette University

Brief Summary

In this three-month interventional clinical trial for the treatment of gingivitis the investigators will assess the use of an oscillating-rotating powered toothbrush in comparison to the use of a manual toothbrush over 12-weeks in the absence of interproximal hygiene.

Detailed Description

In this single-masked, parallel-armed, interventional clinical trial for treatment of gingivitis the investigators will assess the use of an oscillating-rotating powered toothbrush in comparison to the use of a manual toothbrush over 12-weeks in the absence of interproximal hygiene. The primary outcome variable is the change from baseline in the Modified Gingival Index at 2, 4 and 12-weeks from Baseline. Secondary outcome variables include change from baseline in bleeding on probing as well as change from baseline in the Turesky Modification of the Quigley-Hein Plaque index measuring overnight plaque formation. There will also be an assessment of single use efficacy in reduction of overnight plaque levels at the baseline visit t

Arm && Interventions

Group	Intervention	Description
Powered toothbrush intervention	Oscillating rotating power toothbrush	Subjects will be provided an oscillating rotating powered toothbrush as the experimental intervention, and given written instructions on its proper use. Efficacy of overnight plaque reduction will be assessed at baseline and both gingivitis and plaque reduction will be assessed as change from baseline at 2, 4 and 12 weeks. Subjects will be given a standard fluoride toothpaste and asked to refrain from daily interproximal plaque control for the duration of the study.

Primary Outcome Measures

Name	Time	Method
Change in Gingivitis	12 weeks post-baseline	Baseline and 12 weeks post-baseline measures. Proportion of bleeding sites per patient was used as Full mouth BOP Score. The score for each site was either 1 for bleeding and 0 for no bleeding.; Following is the full description of each outcome measure reported in the protocol.; The Modified Gingival Index3 (MGI) will be measured on six sites - mesio-buccal, buccal, disto-buccal, mesio-lingual, lingual and disto-lingual - of all teeth using a 0-4 scale. Lower score no inflamation and higher severe inflammation.; Dental plaque will be evaluated using the Lobene modification4 of the Turesky modification of the Quigley-Hein Plaque Index (PI)5. The score 0 to 5. Lower score means no plaque and higher score increasing plaque.Full-mouth Probing Pocket Depth (PPD) will be measured on the six locations of each tooth (mesial-buccal, buccal, distal-buccal, mesial-lingual, lingual, distal-lingual) using a periodontal probe.
