Conditions

Motivational Interviewing, BMI, OHI

Brief summary

The goal of this research study is to determine if the utilization of brief motivational interviewing (BMI) during continuous care is superior compared to traditional oral hygiene instruction (OHI) to reduce patients' plaque score, bleeding on probing (BOP), and gingival index (GI) longitudinal. An additional goal is to investigate chairside time of implementing BMI.

Interventions

BEHAVIORALBMI

A derivative of motivational interviewing (MI), which is a patient-centered, collaborative counseling approach to strengthen an individual's intrinsic motivation towards a positive behavior change. BMI is intended for healthcare providers with limited time (5-10 minutes) to support a positive behavior change.
