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.

Masking description

Outcomes assessors and the principal investigator will be blind to toothbrush device assignment. In order to maintain blinding and eliminate assessor bias, study team members instructing and observing participants in the use of the assigned toothbrushing device will not be outcomes assessors.

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.

Recruitment details

subjects were recruited via flyers posted at the Center for Pediatric Dentistry at the University of Washington. If parents were interested they contacted the study coordinator for a phone screening.

Pre-assignment details

62 parents called for a phone screening. Of those,48 subjects presented for the first appointment but 6 were not enrolled due to not meeting inclusion and exclusion criteria. 42 subjects were consented and enrolled.

Participants by arm

ArmCount
Automated Mouthpiece-based Toothbrush
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. Automated mouthpiece-based toothbrush: One-time use during study visit.
22
Manual Toothbrush
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. Manual toothbrush: One-time use during study visit.
