Patient Education, Periodontal Diseases, Self-Care
Conditions
Brief summary
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.
Detailed description
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.
Interventions
BEHAVIORALMotivational interview vs. prevailing education
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bleeding on probing (BoP) | Up to 6 month | 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. |
| Pocket probing depth (PD) | Up to 6 month | 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. |
| Clinical Attachment Level (CAL) | Up to 6 month | 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. |
