About this study

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.

Read the 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.

Being tested
Fluoride varnish, Oral health education, Dental services delivered by the Indian Health Service.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluation of Decayed, Missing, and Filled Tooth Surfaces (Dmfs) at Baseline

    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.

    Measured: Baseline

  2. Evaluation of Decayed, Missing, and Filled Tooth Surfaces (Dmfs) at Year 1

    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.

    Measured: 1 Year

  3. Evaluation of Decayed, Missing, and Filled Tooth Surfaces (Dmfs) at Year 2

    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.

    Measured: 2 Years

  4. Evaluation of Decayed, Missing, and Filled Tooth Surfaces (Dmfs) at Year 3

    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.

    Measured: 3 Years

Secondary outcomes (4)
  1. Acquisition of Dental Attitudes and Behaviors of the Caregivers of the Children

    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. The survey assessing attitudes and behaviors is comprised of 12 items. Scores are calculated as a percentage of appropriate responses. Therefore, possible scores range from 0-100.

    Measured: Over 3 years

  2. Evaluation of Caries Patterns

    Caries patterns will be studied in terms of the specific teeth and tooth surfaces that are affected. Caries prevalence is defined as the presence of more than 0 dmfs (decayed, missing, or filled surfaces) in the child participant. The percentage of child participants with caries prevalence is reported.

    Measured: Over 3 years

  3. Comparison of Utilization and Costs of Dental Care

    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.

    Measured: Up to 3 years after randomization

  4. Acquisition of Dental Knowledge of the Caregivers of the Children

    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. The survey assessing knowledge is comprised of 14 items. Scores are calculated as a percentage of correct answers. Therefore, possible scores range from 0-100.

    Measured: Over 3 years
