The aim of this study is to describe the prevalence, severity, and extent of periodontitis in the adult population of circumpolar communities in Norway using data from the Tromstannen-Oral Health in Northern Norway study.
In this cross-sectional survey, data were collected from a randomized population sample (aged 20 to 79 years) in Northern Norway. Periodontal conditions were assessed for 1,911 dentate adults with a full-mouth periodontal examination. Probing depth (PD) and bleeding on probing were measured at six sites per tooth. Radiographic bone loss (BL) was examined using orthopantomograms.
According to the Centers for Disease Control and Prevention/American Academy of Periodontology case definitions, 49.5% of participants had periodontitis, and 9.1% had severe periodontitis. Periodontitis prevalence and severity increased with age. Extent of BL and PD ≥4 mm also increased with age, but more rapidly and to a greater extent for BL. Prevalence of periodontitis was higher among men and varied between urban and rural areas. Periodontitis prevalence was positively associated with smoking, lower levels of education, and income.
This study reveals a high burden of periodontitis among adults living in circumpolar communities in Norway. The results showed sociodemographic disparities regarding periodontitis and highlights the importance of further investigation of factors influencing periodontal health.
本研究旨在利用来自挪威特罗姆瑟北部口腔健康研究（ Tromstannen-Oral Health in Northern Norway study）的数据，描述挪威北极圈社区成年人群的牙周炎流行率、严重程度和范围。
在这项横断面研究中，数据来自挪威北部的随机人口样本（年龄在 20 至 79 岁之间）。对 1911 名有全口牙周检查的有牙成年人进行牙周状况评估。每颗牙齿的六个部位测量探诊深度（PD）和探诊出血。使用全景片检查放射状骨丧失（BL）。
根据疾病控制和预防中心/美国牙周病学会的病例定义，49.5%的参与者患有牙周炎，9.1%患有严重牙周炎。牙周炎的流行率和严重程度随年龄增长而增加。BL 和 PD≥4mm 的范围也随年龄增长而增加，但 BL 的增加速度更快，程度更大。男性的牙周炎患病率更高，城乡之间存在差异。牙周炎的患病率与吸烟、教育程度较低和收入有关。
本研究揭示了挪威北极圈社区成年人中牙周炎的高负担。结果显示，牙周炎存在社会人口统计学差异，并强调了进一步调查影响牙周健康因素的重要性。
