2. Inflammatory reactions in the gingiva and the periimplant mucosa
Abstract : The purpose of the present series of investigations was to study the tissue response to plaque formation at teeth and implants as well as local mechanisms involved in the regulation of the inflammatory process. The reaction of the periimplant mucosa (PiM) to long-standing plaque accumulation on implant abutments with different surface roughness was analysed in the dog model (Study I). READ MORE

5. The Role of gingivitis in the loss of periodontal attachment and teeth
Abstract : In randomized parallel longitudinal studies conducted in Norway between 1969 and 1995, and Sri Lanka between 1970 and 1990 the initiation and progression of periodontal disease was investigated. The two groups showed geographical, racial, cultural, socioeconomic and educational differences, and they represented extremes as to perceived severity of periodontal disease, general health care delivery systems and to dental care.
