- OBJECTIVES: The aim of the Tromstannen - Oral Health in Northern Norway (TOHNN) study was to investigate oral health and dental-related diseases in an adult population. This article provides an overview of the background of the study and a description of the sample characteristics and methods employed in data collection.STUDY DESIGN: Cross-sectional population-based study including a questionnaire and clinical dental examination.METHODS: A randomly selected sample of 2,909 individuals (20-79 years old) drawn from the population register was invited to participate in the study. The data were collected between October 2013 and November 2014 in Troms County in northern Norway. The questionnaire focused on oral health-related behaviours and attitudes, oral health-related quality of life, sense of coherence, dental anxiety and symptoms from the temporomandibular joint. The dental examinations, including radiographs, were conducted by 11 dental teams in 5 dental offices. The examination comprised of registration of dental caries, full mouth periodontal status, temporomandibular disorders, mucosal lesions and height and weight. The participants were grouped by age (20-34, 35-49, 50-64 and 65-79) and ethnicity (Norwegian, Sámi, other European and other world).RESULTS: From the original sample of 2,909 individuals, 1,986 (68.3%) people participated, of whom 1,019 (51.3%) were women. The highest attendance rate was among women 20-34 years old (80.3%) and the lowest in the oldest age group of women (55.4%). There was no difference in response rate between rural and urban areas. There was a positive correlation between population size and household gross income (p < 0.001) and education level (p < 0.001). The majority of Sámi resided in smaller municipalities. In larger cities, most participants used private dental health care services, whereas, in rural areas, most participants used the public dental health care service.CONCLUSION: The TOHNN study has the potential to generate new knowledge on a wide range of oral health conditions beneficial to the population in Troms County. Due to the high participation rate, generalization both nationally and to the circumpolar area ought to be possible.

- BACKGROUND: The aim of this study was to describe the prevalence, severity and extent of periodontitis in the adult population of circumpolar communities in Norway using data from the study Tromstannen - Oral Health in Northern Norway.METHODS: In this cross-sectional survey, data were collected from a randomized population sample (20-79 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 (BoP) were measured at six sites per tooth. Radiographic bone loss (BL) was examined using orthopantomograms.RESULTS: According to the CDC/AAP case definition, 49.5% of participants had periodontitis and 9.1% had severe periodontitis. Periodontitis prevalence and severity increased with age. The extent of BL and PD ≥ 4 mm also increased with age, but more rapidly and to a greater extent for BL. The 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.CONCLUSIONS: 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.

- OBJECTIVES: The aim of the study was to examine the prevalence and distribution of dental caries in an adult population and identify factors associated with being caries free.MATERIAL AND METHODS: Data were collected from a randomized population sample in Northern Norway (N = 1932; 988 women; mean age 47.0 years, SD 15.3). The study included a structured questionnaire and a clinical examination. The sum of enamel and dentine caries, DS1-5, formed the main outcome measures for caries prevalence.RESULTS: Mean DMFT was 15.1 (95% CI 14.8, 15.4), mean DFT was 12.0 (CI 11.7, 12.2), and mean DT was 1.1 (CI 1.0, 1.2). The mean value for dentine caries (DS3-5) was 0.8 (CI 0.7, 0.9), and mean DS1-5 was 3.8 (CI 3.6, 4.1). Mean DS1-5 was highest in the youngest age group (mean 6.9, 95% CI 6.3, 7.6) and in rural areas (mean 5.0, CI 4.4, 5.6). The most caries-prone 20% in the youngest age group had 52% of the total number of carious lesions compared with 80% in the two oldest age groups. Tooth brushing twice daily (p = .005), drinking sugar containing soft drink (p =.029), and attending dental services every year (p < .001), were associated with being caries free.CONCLUSION: Dental caries is still a common condition, particularly in the youngest age group. Living in a rural area, low socioeconomic status, less frequent tooth cleaning and sugar containing soft drinks were associated with a higher prevalence of dental caries. The different caries distribution among adults calls for different preventive strategies at both population and individual levels.
