NCT07307313

Brief Summary

The goal of this clinical study is to compare the effect of motivational interviewing (MI) and traditional patient education methods in improving oral hygiene (plaque score and bleeding score) among young children 8-10. It will also assess the demographic (age and sex) and socioeconomic indicators' effect on oral hygiene (plaque score and bleeding score) after intervention. The main questions this study aims to answer are:

  • Is MI significantly more effective in improving oral health (plaque score, bleeding score) among children when compared to traditional patient education methods?
  • Are there specific demographic or contextual factors (e.g., age, socioeconomic status, baseline oral health status) that influence the effectiveness of MI in promoting oral health among children when compared to traditional patient education methods? Participants will be randomly assigned to three groups to receive oral hygiene instructions: verbal and written, video, and motivational interviewing. Have their oral hygiene assessed using the plaque index and bleeding index before the intervention and after a follow-up period of 1 month.

Outcome Measures

Primary Outcomes (2)

  • Plaque index

    The primary researcher will document the plaque index for each patient prior to the intervention and after the follow-up appointment after 1 month using Plaque Control Index scoring

    From enrollment to the 4-week follow-up appointment

  • Bleeding index

    The primary researcher will document the bleeding index for each patient prior to the intervention and during every follow-up appointment using Gingival Bleeding Index (GBI)

    From enrollment to the 4-week follow-up appointment
