Brief summary
This study evaluates behavioral interventions to increase adolescent's motivation for self performed periodontal infection control, by means of adequate oral hygiene. Study subjects will be allocated to test and control group where the test will be subjected to an individually tailored oral health education program, based on cognitive- behavioral theory and principles, and the control to standard educational intervention.
Detailed description
The prevalence of chronic periodontitis is about 40% among the Swedish adult population. The key-factor for the prevention of periodontal disease progression is the establishment of periodontal infection control, by means of adequate daily oral hygiene. Hence, a main task for dental professionals is to educate and motivate the patient to such beneficial behavior. A hypothesis for the current study is that patient centered health promotion programs based on cognitive behavioral theory and principles and with a directive communicative approach, i.e. motivational interviewing techniques, add positive and lasting effects to standard educational interventions on self-performed periodontal infection control. This randomized clinical field study involves 30 professionals (dental hygienists) and about 350 adolescent patients at 16 dental clinics in the Västra Götaland Region, Sweden. The approach in the evaluation is on patient-centered outcomes and health economics.
Interventions
BEHAVIORALPatient centered oral health education
Procedure: The theory-based educational intervention follows a specific structure. The initial phase contain 3 treatment sessions (45-60 min each) during a period of 12 weeks (baseline, 2-3 weeks and 10-12 weeks). Follow up are performed at 6- and 18-months.
BEHAVIORALStandard educational intervention
Procedure: The initial phase contain educational intervention in accordance with conventional routines (oral health information and oral hygiene instruction at one or several occasions). Follow up are performed at 6- and 18-months.

Inclusion criteria
* 16 or 17 years old at inclusion * poor oral hygiene conditions (dental plaque and/or marginal gingival bleeding at \>50% of tooth surfaces) at the time of examination and thus considered to be at increased risk for oral/periodontal disease progression.
