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

Not Applicable

• Conditions: Periodontal Diseases; Self-Care; Patient Education
• Interventions: Behavioral: Motivational interview vs. prevailing 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.

Arm && Interventions

Group	Intervention	Description
Prevailing education	Motivational interview vs. prevailing education	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.
Motivational interview	Motivational interview vs. prevailing education	The MI-intervention is used as a part of normal dental hygienist appointment. 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. Dental hygienist support patients in decision making although patients were addressed as an active agent.

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.
