Study summary

This is a randomized clinical trial to test the efficacy of a parent-targeted text message-based intervention program on caries incidence and oral health behaviors (child and parent). Parents (n= 850) across all pediatric clinic sites (Boston Medical Center and Community Health Centers (CHCs); DotHouse CHC, South End Community Health Center, and Codman Square CHC) will be randomized to receive either text messages (TMs) regarding oral health or TMs regarding child wellness. The study will enroll English and Spanish speaking parents and their youngest child who is \< 7 years old, has at least one tooth showing, and attends the targeted pediatric clinic to receive primary care (n= 1700). Parents will complete self-report surveys at baseline, and 2, 4, 12, and 24-months after baseline; receive and respond to TM assessments during the 4-month intervention; and will also receive TMs during a 'booster' period of one month, which will occur 12-months post baseline. Parent's children will be assessed for caries by a clinical oral examination performed by licensed Clinical Examiners at baseline, 12-and-24-months post-baseline.

What researchers measure

Primary outcomes

  1. Dental Caries Increment

    Surface level caries data in children was collected by calibrated clinical examiners (blind to treatment condition), utilizing the OHDC Modified ICDAS methodology, will allow calculation of caries increment (development of a new cavitated lesion or filled surface on a previously sound tooth surface).

    Time frame: 24-month time point (oral assessment)

  2. Parent/Caregiver Confidence to Brush

    9-item self-efficacy measure to assess parent/caregiver participant confidence in their ability to brush their child's teeth under different situations. (Finlayson measure; range 1 - 4; higher scores mean better outcome)

    Time frame: 4-month time point (survey)

  3. Parent/Caregiver Motivation to Perform Oral Health Behaviors

    A oral health motivation measure to assess parent/caregiver participants motivation to engage in recommended child oral health behaviors (score range 1 - 7; higher scores mean better outcome)

    Time frame: 4-month time point (survey)

  4. Parent/Caregiver Outcome Expectations for Oral Health Behaviors

Results

Posted May 18, 2023
Limitations and caveats
Due to the COVID-19 pandemic, on March 12, 2020 Boston University Medical campus and Boston Medical Center IRB declared an immediate halt of in-person research activities. This resulted in a less than expected number of children attending the 12 and/or the 24 month oral health assessments.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2018 to primary completion in Feb 2022, 47 months.

Results were first posted in May 2023, 1 year 2 months after primary completion.

Of 469 non-industry interventional studies with no phase under Dental Caries, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 30. This study's 47 months is above that.

Counting every sponsor, half of 502 studies reached it within 15 months; a quarter within 7 and three quarters within 29.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 24, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
