Abstract
AIM: This cross-sectional study assesses the prevalence of periodontitis in a large Norwegian population, based on the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions. The prevalence of periodontitis was determined by bone loss recorded on radiographs (OPG and BW) and by clinical examination. METHODS: As part of a large population health study (The HUNT Study) 7347 participants above the age of 19 were invited to the HUNT4 Oral Health Study. Radiographic bone loss and periodontal assessment of stage and grade, were determined in 4863 participants. RESULTS: Periodontal examination was performed in 4863 participants. Radiographic bone loss and clinical registrations corresponding to periodontitis as defined was observed in 72.4%. The prevalence of periodontitis increased after 40 years of age, with severe forms occurring primarily after 60 years of age. Stage I was observed in 13.8%, Stage II was observed in 41.1%, Stage III was observed in 15.3% and Stage IV was observed in 2.3% of the population. Grade A, B and C was observed in 5.7%, 60.2% and 6.2%. CONCLUSION: Periodontitis was frequently observed in the investigated population. The prevalence of periodontitis Stage III and Stage IV combined, was observed in 17.6% of the study population. This article is protected by copyright. All rights reserved.
