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

University of Turku28 enrolled

Overview

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.

In intervention group dental hygienists are trained to focus on patients view of their oral health, self-care skills and need for oral-health related behaviour change. They are supposed to use open-ended questions, reflective listening and reinforcing with patients. In control croup dental hygienist defined patients educational needs and gave direct instructions how to change behaviour and self-care.

Outcomes

Primary Outcomes

Bleeding on probing (BoP)

Change in BoP is measured three times during the study. In the baseline and in the tree- and six-months follow-up. Bop is recorded60 seconds after the pocket probing and assessed as present (1) or absent (0) on four surfaces.

Time frame: Up to 6 month

Pocket probing depth (PD)

Change in PD is measured three times during the study. In the baseline and in the tree- and six-months follow-up. PD is measured at mesial, distal, lingual and buccal surfaces.

Time frame: Up to 6 month

Clinical Attachment Level (CAL)

Change in CAL is measured three times during the study. In the baseline and in the tree- and six-months follow-up. CAL is measured if cemento-enamel junction is uncovered or if there is 6 mm deep or deeper gingival pocket.

Time frame: Up to 6 month
