University of Colorado, Denver
ClinicalTrials.gov Identifier:
NCT01116739
First received: May 3, 2010
Last updated: January 18, 2017
Last verified: January 2017
  Purpose
An intensive intervention of specially trained paraprofessionals, called community oral health specialists (COHS), administering on a quarterly basis for 2 years fluoride varnish and oral health promotion education, compared to usual care, will reduce decayed, missing, and filled tooth surface measures at 2 years for children in American Indian Head Start Programs.

Condition Intervention Phase
Early Childhood Dental Caries Device: Fluoride varnish Behavioral: Oral health education Other: Dental services delivered by the Indian Health Service. Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Outcomes Assessor
Primary Purpose: Prevention

Further study details as provided by University of Colorado, Denver:

Primary Outcome Measures:
  • Evaluation of decayed, missing, and filled tooth surfaces (dmfs) [ Time Frame: Over 3 years ]
    The number of decayed, missing, and filled tooth surfaces (dmfs) for each child. The dental examiners will be trained and calibrated, and standardized criteria and instruments will be used for the detection of the dental caries.


Secondary Outcome Measures:
  • Acquisition of dental knowledge, attitudes, and behaviors of the caregivers of the children [ Time Frame: Over 3 years ]
    An automated computer assisted survey interview (ACASI)will be done of the caregivers of the children. The questions have been standardized across 6 studies from the Collaborating Research Centers to Reduce Oral Health Disparities.

  • Evaluation of caries patterns [ Time Frame: Over 3 years ]
    Caries patterns will be studied in terms of the specific teeth and tooth surfaces that are affected.

  • Comparison of utilization and costs of dental care [ Time Frame: Up to 3 years after randomization ]
    Utilization and costs of dental care received by the children in the study will be compared, as well as the costs of the intervention program.


Estimated Enrollment: 1040
Study Start Date: April 2011
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: COHS administered fluoride varnish and oral health education
Paraprofessionals, called community oral health specialists (COHS), will be trained to administer fluoride varnish and oral health education to head start children quarterly for 2 years.
Device: Fluoride varnish
Fluoride varnish will be administered by the COHS quarterly for 2 years.
Behavioral: Oral health education
Oral health education will be provided quarterly for 2 years. It will include information about how to mitigate the known risk factors for early childhood dental caries.
Active Comparator: Usual care
Usual care will include regular dental services provided by the Indian Health Service.
Other: Dental services delivered by the Indian Health Service.

Detailed Description:
The study design will be a clustered randomized design. Fifty-two head start classes in a Southwest American Indian Reservation will be randomized, 26 to the intervention program and 26 to usual care. The intervention will be comprised of specially trained paraprofessionals, called community oral health specialists (COHS), administering fluoride varnish and oral health promotion education quarterly for 2 years. Baseline and annual measures of decayed, missing, and filled tooth surfaces (dmfs) of the children, and surveys of their caregivers' dental knowledge, attitudes, and behaviors will be completed. The study will be a 5-year study, with 2 years for intake/accrual, and 3 years of follow-up.
