My research comprise several areas in Oral health:
- Stress and depression in relation to gingival inflammation/periodontitis
- A new treatment method for peri-implantitis
- Smoking and inflammation
- Oral health among persons with Crohns disease
- Toothbrush with incorporated blue LED light on gingival inflammation
- Oral health among adolescents, adults, and elderly
- Systematic reviews
- Dental Hygienist profession
To achieve good oral health is one of the most significant tasks in order to maintain a good quality of life and well-being. My line of research emphasizes this goal and therefore it is very important.
My research include both quantitative, qualitative, and pedagogical studies.

Projects
Peri-implantits
The project compare treatment of peri-implantitis with either 970 nm laser or conventional mucosal flap surgery, to measure clinical parameters, inflammatory and microbial response. The project includes an in-vitro study with the aim to investigate the effects of laser on e.g., the surface structure of dental implants. Deep interviews will clarify the patients' experiences about these different treatment methods. We will also compare the immune cell profile in peri-implantitis with the immune cell profile in periodontitis and health lesions.
Theory-based behavioural interventions – A pedagogic and patient centered project
Comprehensive dental care should include effective, evidence-based behavioural methods (such as qualified counselling and/or theory-based counselling) for the patient education, intended to achieve long-term lifestyle changes and behaviours or importance to oral health. The overall aim is to explore the existing teaching regarding the use of behavioural intervention methods, identify and obstacles and design a separate syllabus within this topic, to achieve better oral health and quality of life among the patients. To identify prerequisites and limitations for using theory-based behavioural interventions among the dental hygienist by questionnaires and in-depth interviews. And explore the patients’ perspectives regarding these methods to see if it can affect oral health and quality of life.

Systematic reviews
In another ongoing systematic literature dental erosions is studied based on different issues such as diagnosis, treatment, and prevention. Collaboration with SBU and Eastman Institute.
Dental Hygienist profession today and a future perspective
The purpose is to identify the stakeholders view of the dental hygienist profession regarding tasks and skills today and from a future perspective. The project will identify important aspects regarding the dental hygienist's competence and the content of dental hygiene education and also the continuing education to be able to meet the future social need. Both a web-based survey and depth interviews with stakeholders will be carried out. Collaboration with co-workers at KI.
