Study summary

This study assesses the impact of oral health promotion delivered by community health workers in medical clinics, Women, Infants and Children (WIC) centers, and family homes. Investigators will assess oral health behaviors in children aged 0 to 3.

Read the detailed description

Dental caries is the most common chronic disease of childhood; an estimated 28% of children nationally aged 5 years and below have untreated dental disease. Pediatric dental caries are associated with pain, more severe infections, malnutrition, speech difficulties, poor school performance, cosmetic problems, and an overall lower quality of life. Similar to other chronic diseases, oral health disparities are seen with higher caries prevalence and worse outcomes in children from low income urban families and in children of African American and Latino ethnicity. These disparities have been demonstrated locally in Chicago. Many interventions have been implemented to attempt to reverse these disparities. Some involve public policy (fluorinated water), some are educational campaigns targeting individuals, while others focus on providing increased education and services through primary healthcare providers. Many of these programs have demonstrated efficacy but the disparities in oral health persist. The investigators propose this is because the interventions to date do not target the family as a whole and also have not targeted multiple levels simultaneously.

COordinated Oral health Promotion (CO-OP) Chicago brings together a team of clinical pediatricians and dentists, health researchers, and policy experts to rigorously test the ability of multiple oral health promotion interventions, both alone and in combination, to improve child and family oral health. The primary intervention is family-focused education and support from community health workers (CHWs). CO-OP Chicago will test the impact of a family-focused CHW intervention for oral health promotion when applied in clinical, community, and home settings. The primary study objective is to evaluate the efficacy of a one-year oral health CHW intervention, compared to usual care, to improve self-reported brushing frequency and observed plaque score in low income urban children under the age of 3 years old. The study's exploratory aim is to determine if the oral health CHW intervention impact on child tooth brushing behaviors varies when the CHWs are based out of a medical clinic compared to a community WIC center.

Inclusion criteria

Caregiver:

  • The child must be an active patient/client in the clinic/center where recruited.
  • Speak English or Spanish
  • Willing to comply with all study procedures and be available for the duration of the study

Child:

  • Age 6-36 months old
  • An active patient/client in the clinic/center where recruited
  • A minimum of two fully erupted central maxillary incisors

Exclusion criteria

Exclusion Criteria:

  • Child with medical condition that limits his or her ability to conduct the study activities (such as severe developmental or cognitive delay, ventilator or oxygen dependence, oral aversion, severe facial deformities)
  • Anything that would place the individual at increased risk or preclude the individual's full compliance with or completion of the study
  • Anything that would place the research or intervention staff at increased risk
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    CHW Arm

    The intervention is community health worker (CHW) services. CHWs trained in oral health will be assigned to half of the sites. Participants in these sites will be offered four in-person visits and follow-up phone calls over 12-months. These visits can occur at the location of the family's preference (recruitment site, home, or mutually-agreed upon other location). A core curriculum of oral health topics will be covered during visits, with an emphasis on developing and sustaining healthy oral health management routines for the entire family.

    Behavioral: Community Health Worker (CHW) services

  • No intervention
    Wait-list Control Arm

    This arm will receive usual care. After completion of the final data collection at one year, participants and sites allotted to this arm will be offered CHW services.

Interventions

  • BehavioralCommunity Health Worker (CHW) services

    CHWs are non-clinical people who provide education, care coordination, and support to families.

What researchers measure

Primary outcomes

  1. Parent-reported Tooth Brushing Frequency

    parents will be asked how often the child's teeth are brushed

    Time frame: 12-months post-randomization

  2. Child Dental Plaque Score

    Disclosing solution is applied to child's teeth, images are taken, and plaque score is determined using the Oral health Index - Maxillary Incisor Score (OHI-MIS). The buccal surfaces of teeth #D, E, F, and G were scored from 0-3, with 3 being the worst (plaque on more than 2/3 of tooth surface) and 0 being the best (no plaque present). The four individual tooth scores (or less if child did not have four teeth) were then added and divided by the number of teeth for a final average score ranging from 0-3.

    Time frame: 12-months post-randomization

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 Jan 2018 to primary completion in Aug 2020, 31 months.

Results were first posted in Dec 2021, 1 year 3 months after primary completion.

Of 568 non-industry interventional studies with no phase under Health Behavior, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 33. This study's 31 months is above that.

Counting every sponsor, half of 586 studies reached it within 15 months; a quarter within 5 and three quarters within 32.

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 18, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
