About this trial

This is an interventional treatment trial for Dental Plaque focused on measuring Gingivitis, toothbrushing, oral hygiene, biofilm

Eligibility Criteria

5 Years - 17 Years (Child)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Between the ages of 5-17
  • In good general health
  • Fluent in English
  • Parent or guardian willing and able to provide written informed consent
  • Have 16 scoreable teeth (non-crown/bridge/or full amalgams)

  • Mouth or teeth pain that prevents brushing in any areas
  • Intraoral piercings (tongue or lip) that cannot be removed
  • Non-controlled diabetes
  • Any autoimmune or infectious disease or any medical condition that would delay wound healing

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Automated mouthpiece-based toothbrush

Manual toothbrush

Arm Description

Under observation of study staff, participants assigned to the automated mouthpiece-based toothbrush will insert a properly fitted mouthpiece and use the automated device directly over the sink.

Under observation of study staff, participants assigned to the manual toothbrush will be timed brushing their teeth directly over the sink using a pre-dispensed quantity of toothpaste on bristles dampened with water.

Outcomes

Primary Outcome Measures

Change From Baseline in Dental Plaque Removal Efficacy Using Turesky Modification of the Quigley-Hein Plaque Index
Average Change from baseline plaque index after brushing with the automated mouthpiece-based brushing device versus a manual toothbrush. The Turesky Modification of the Quigley-Hein Plaque Index evaluates 6 areas per tooth and gives a score from 0-5 with 0 being no plaque and 5 being the highest amount of plaque and the average score for all sites was used for analysis.

Secondary Outcome Measures

Change From Baseline in Presence of Soft Tissue Abrasion After Use of Automated Mouthpiece-based Brushing Versus Manual Toothbrush
Number of participants with soft tissue abrasion after brushing with the automated mouthpiece-based.brushing device versus a manual toothbrush. An intraoral soft tissue examination will be done before and after brushing and a binary scale will be used to note any areas of abrasion (yes or no). Outcome is the presence of any soft tissue abrasion that was not present prior to brushing.

5. Study Description

Brief Summary
The purpose of this research study is to compare how a novel, automated mouthpiece-based toothbrushing device removes dental plaque compared to a manual toothbrush.
Detailed Description
Plaque is one of the main etiological factors in dental decay and the principal etiological factor for periodontal diseases. Although toothbrushes have greatly evolved, dexterity is still the key component to an efficient cleaning routine. The primary goal is to examine 60 participants to determine the efficacy of a new powered teeth cleaning device designed to bypass the variability of individual dexterity compared with manual toothbrushing. This is a single-blind, randomized controlled trial. Sixty pediatric patients will be recruited for the study and randomized into treatment and control groups, subdivided into primary (20), mixed (20), and permanent dentition (20). Participants will be asked to abstain from brushing, flossing, gum or mouthwash use for 24 hours prior to the study visit. Plaque will be assessed using the Turesky Modification of the Quigley-Hein Plaque Index before and after a one-time brushing with the assigned study device. A soft tissue assessment will be conducted and intraoral photos taken pre- and post-brushing.
