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.

Conditions

Periodontal Diseases; Patient Education; Self-Care

Outcome Measures

Primary Outcomes (3)

• 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.

  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.

  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.

  Up to 6 month

Study Arms (2)

Motivational interview

ACTIVE COMPARATOR

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.

Behavioral: Motivational interview vs. prevailing education

Prevailing education

ACTIVE COMPARATOR

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

Motivational interview vs. prevailing education BEHAVIORAL

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.
