Outcome Measures

Primary Outcomes (8)

  • Change from Baseline in Plaque Score at 1 month

    Plaque levels will be scored for each participant based on photographs taken after the use of a plaque disclosure tablet. This will be scored as low (minimum), moderate, or high (maximum). Lower is better.

    At baseline and post-intervention (after about one month)

  • Change from Baseline in Gum Bleeding at 1 month.

    Each participant will use a toothpick to probe 14 points in the mouth (7 points in the maxillary anterior teeth and 7 points in the mandibular anterior teeth). At each point, if the participant bleeds, they are given a score of "1". Then the score is added up at the end of probing each point. Minimum score is 1 and maximum score is 14. Lower score is better and higher score is worse.

    at baseline, and post-intervention (after about one month)

  • Change from Baseline Weekly Toothbrushing at 1 month.

    Each participant will self-report frequency of toothbrushing in the past 7 days on a survey. This will be scored as a continuous count (minimum is zero, no set maximum) and whether or not they met ADA recommended guidelines for twice daily brushing. Higher frequency is better.

    at baseline, and post-intervention (after about one month)

  • Change from Baseline in Weekly Flossing at 1 month.

    Each participant will self-report frequency of flossing in the last 7 days on a survey. This will be scored as a continuous count (minimum is zero, no set maximum) and whether or not they met ADA recommended guidelines for once daily flossing. Higher frequency is better.

    at baseline, and post-intervention (after about one month)

  • Change from Baseline in Weekly Rinsing at 1 month.

    Each participant will self-report frequency of rinsing with water in the last 7 days on a survey. This will be scored as a continuous count (minimum is zero, no set maximum). Higher frequency is better.

    at baseline, and post-intervention (after about one month)

  • Change from Baseline Oral Hygiene at 1 month.

    Each participant's oral hygiene skill level will be assessed and scored as poor (minimum), fair, good, or excellent (maximum) based on execution of specific micro-behaviors for brushing and flossing. Higher is better.

    at baseline, and post-intervention (after about one month)

  • Change from Baseline Count in S. Mutans Bacteria in Saliva at 1 month.

    Saliva samples will be collected using Zymo collection kits to run qPCR analysis, which will yield information on whether or not bacteria is present (yes/no), and relative and absolute counts of S. mutans bacteria. Minimum is zero, no set maximum. Lower is better.

    at baseline, and post-intervention (after about one month)

  • Change from Baseline Count in S. sobrinus Bacteria in Saliva at 1 month.

    Saliva samples will be collected using Zymo collection kits to run qPCR analysis, which will yield information on whether or not bacteria is present (yes/no), and relative and absolute counts of S. sobrinus bacteria. Minimum is zero, no set maximum. Lower is better.

    at baseline, and post-intervention (after about one month)

Study Arms (2)

Motivational Interviewing and Assessments

EXPERIMENTAL

Two 1 hour assessments. At each assessment, participant will complete a survey, supply a saliva sample, do a toothpick test, and take a plaque photo. Three one-on-one, half hour educational and skill-building MI sessions will address: proper oral hygiene technique, bacteria and dental caries process, and nutrition. Intervention group adolescents will also receive three calls over one month reinforcing their hygiene behavior goals.

Behavioral: Motivational Interviewing

Assessments Only

NO INTERVENTION

Two 1 hour assessments. At each assessment, participant will complete a survey, supply a saliva sample, do a toothpick test, and take a plaque photo.

Interventions

Intervention will include 3 one-on-one motivational interviewing sessions and 3 follow-up calls with a trained MI health educator. These sessions aim to promote better oral hygiene and oral health.
