RESUMO
BACKGROUND: The relationships between periodontitis and non-communicable diseases (NCDs) have been investigated through several different case-definitions. The differences in methodology may have hindered the basis of comparison between these studies. The classification from the 2017 World Workshop on the Classification of Periodontal and Peri-implant Diseases and Conditions offers a unison platform that may facilitate future comparison of such research. The present study aimed to reproduce associations between periodontitis and other NCDs using the 2017 Classification, in the Trøndelag Health Study (HUNT). MATERIAL AND METHODS: The fourth HUNT-survey was carried out between 2017 and 2019. Clinical variables, blood samples and answers to questionnaires were collected from 4933 participants. Periodontal status was assessed based on the latest staging system, and its associations with NCDs were estimated by logistic regression models adjusted for potential confounders. RESULTS: Compared to no or Stage I periodontitis, participants with Stage III/IV periodontitis (radiographic bone loss exceeding 33%) were associated with cardiovascular disease, hyperglycemia in participants with diabetes and chronic obstructive pulmonary disease (COPD)/emphysema. Associations with hyperglycemia in participants with diabetes and COPD/emphysema were also observed in participants with Stage II periodontitis. The only observed association when considering never-smokers alone, was with COPD/emphysema. CONCLUSION: Periodontitis Stage II and III/IV were associated with major NCDs. Effect sizes increased with increasing periodontitis stages, which implies greater occurrence of coincident comorbidities in patients with severe periodontitis.

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 (orthopantomogram [OPG] and bitewing [BW]) and by clinical examination. MATERIALS AND METHODS: As part of a large population health study (The HUNT Study), 7347 participants aged 19 years and older were invited to the HUNT4 Oral Health Study. Radiographic bone loss (RBL) and periodontal stage and grade were assessed in 4863 participants. RESULTS: Periodontal examination was performed in 4863 participants. RBL and clinical registrations corresponding to periodontitis as defined were 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 in 41.1%, Stage III in 15.3%, and Stage IV in 2.3% of the population. Grade A, B, and C was observed in 5.7%, 60.2%, and 6.2%, respectively. 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.
