Supporting Oral Self-care of Patients With Periodontitis Through Motivational Interview

Supporting Oral Self-care of Patients With Periodontitis Through Brief Motivational Interview

The aim of this study was to evaluate the potential additive effect of Motivational Interviewing (MI) on gingival health and self-care. Our hypothesis was that the Motivational Interviewing would result in improved gingival health and self-care compared to prevailing patient education.

The study is designed as a randomized, double-blinded, controlled clinical trial of 6-month duration involving patients with diagnosed periodontitis. The subjects are randomized to intervention or control group using the randomizing list.

For both groups, necessary non-surgical periodontal treatments will be done. In the intervention group The MI-intervention is used as a part of normal dental hygienist appointment and if patient need more than one visit, MI was used in every visit.

In control group prevailing, more professional-centered education is used. Dental hygienist define patients educational needs and give direct instructions how to change behaviour and self-care.
