Oral Health

The research in oral health focuses on treatment of peri-implantitis, the capitation contract system in Sweden, and pedagogical projects.

Principal Investigator

Project: Laser and Peri-implantitis

This project is about evaluating diode laser in the treatment of peri-implantitis. The aims are to evaluate the laser in combination with scaling and rootplaning compared to surgical treatment. An in-vitro study will investigate the effects of laser on the surface structure of dental implants. Patient’s experience will also be analysed regarding the two methods and a biopsy study will evaluate the histological differences between periodontitis and peri-implantitis patients and the presence of immune cells. It’s a PhD project.
