Brief summary

The objective is a 3-year follow-up clinical trial to evaluate longitudinal indicators of periodontal disease (plaque score, bleeding on probing (BOP), and gingival index (GI)) in 58 participants who completed NCT03571958. These participants were randomized to a brief motivational (BMI) test group or a traditional oral hygiene instruction (OHI) group for a 1-year clinical trial from 2018-2020. In addition, analysis of retrospective data to determine health topics that emerge from the behavior change strategy of BMI compared to traditional OHI by transcription of audio recordings from 2018-2020.

Interventions

OTHERBMI

Longitudinal data will be collected to determine the effectiveness of BMI compared to traditional OHI to maintain and improve periodontal health.
