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

Not Applicable

• Conditions: Periodontal Diseases; Self-Care; Patient Education

• Registration Number: NCT04023500
• Lead Sponsor: University of Turku

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.

Primary Outcome Measures

Name	Time	Method
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.
