Objectives: We sought to evaluate the mitigating effect of using floss and interdental brushes on periodontal health inequality. Methods: This study was based on data acquired from the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII; 2016-2018). We included 11,359 participants aged ≥19 years in the final analysis. Multivariable logistic regression analysis was performed using socioeconomic characteristics, health behavior, health status, and periodontitis status. We analyzed differences in the prevalence of periodontitis according to household income stratified by the use of floss and interdental brush. Results: In the multivariable logistic regression model, the lowest income group had 1.304 (95% confidence interval [CI] 1.08-1.58) odds ratios for periodontitis than the highest income group. In the interdental brush nonusers or floss nonusers, the lowest income group had significantly higher odds of developing periodontitis. However, we found no significant differences in the periodontitis prevalence between the income groups among the interdental brush users. In the 65-year-old or older group, the same result was observed in the interdental brush and floss users. Conclusions: The results suggest that the use of floss and interdental brushes could alleviate periodontal health inequality.

본 연구는 제6기 국민건강영양조사 자료를 이용하여 사회경제적 요인, 치주질환 및 영구치 우식경험에 따른 구강건강의 격차를 확인하고, 구강건강 관련 삶의 질에 영향을 미치는 융합적 요인을 분석하여 정책 계획의 기초자료를 제시하고자 실시하였다. 연구 대상은 본인이 인지하는 구강상태에 응답한 7,639명으로 하였고, 분석방법은 복합 표본 교차분석과 로지스틱 회귀분석으로 시행하였다. 결과는 연령이 높고, 가구 소득과 교육수준이 낮을수록 주관적 구강건강이 나쁘고, 구강검사를 한 대상자는 구강건강을 좋게, 치주질환이나 영구치우식경험자는 구강건강을 나쁘게 인식하였다. 사회경제적 취약계층, 치주질환 경험자, 영구치우식경험자 등이 구강건강에 부정적임을 확인할 수 있었다. 따라서 이러한 구강건강의 불평등을 근본적으로 해결하기 위한 정책개발이 필요할 것으로 사료된다.

본 연구의 목적은 성인 근로자의 치주질환 유병 여부와 관련하여 인구학적, 구강 행태적 위험 요인을 알아보고자 시행하였다. 연구대상 및 방법은 제5기 3차 국민건강영양조사 자료를 활용하여 20-64세 한국 성인 근로자 1650명을 대상으로 시행하였다. 연구결과, 치주조직 유병자에 대해서 성별, 연령, 소득수준, 교육수준, 전신질환, 수면시간, 구강건강수준, 씹기 문제 및 저작 불편함이 위험요인으로 나타났다. 이중 가장 많은 영향력은 씹기 문제와 저작불편에 문제가 있는 근로자에서 3.5배 이상 치주조직병에 이환될 가능성이 높게 나타났다. 본 연구 결과를 통해서 한국 근로자에 있어서 치주질환 유병의 다양한 위험요인이 존재하고 있음 알 수 있었으며, 향후 치주질환의 유병율을 줄이기 위해서는 정기적인 구강검진과 건강검진, 충분한 수면을 취하고 스트레스를 낮추어야 할 뿐만 아니라, 소득수준과 교육수준의 차이와 같은 사회경제적 불평등 해결을 위한 제도적인 노력이 필요할 것으로 보인다.

Objectives: The purpose of this study is to evaluate the relationship between socioeconomic characteristics and prevalence of periodontal disease in a representative sample of Korean adults older than age 20. Methods: Data of 3,837 adults were collected by the six Korean National Health and Nutrition Examination Survey, which was conducted in 2015. Socioeconomic, demographic, and oral health-related behavior data were collected as independent variables. We determined frequencies, percentage, and determining statistical significance using multiple regression analysis. Results: Prevalence of periodontal diseases showed statistically significant difference in accordance with sex, age, socioeconomic and demographical characteristics and oral health-related behavior. It was confirmed that the prevalence of periodontal diseases was increased in the lower educational level and income (OR, 1.478 and 1.520) after adjusting for conditions such as age, sex, recent dental check-ups, visiting dental clinic, tooth brushing frequency, use of self-care devices. Conclusions: The prevalence of periodontal disease was related with socioeconomic factors in Korean adults. Therefore, differentiated oral health service policies and dental health education among adults with lower education and income is required in order to reduce the prevalence of periodontal disease.

Objectives: In this study, both subjective and objective levels of oral health were used to identify the relationship between oral health inequalities. Methods: Korean National Health and Nutritional Examination Survey data from 2013 to 2015 were combined to create an analysis plan. Oral health questions categorized as subjective oral health conditions and oral health-related diseases used dental tissue disease status as data measured by the Community Periodical Index(CPI) and decayed, missing, filled teeth(DMFT) experience. Other data on oral health behaviors such as toothache experience, the frequency of toothbrush use, chewing problems, oral examination status, and unmet dental care needs were classified and analyzed according to the socioeconomic level. Data were analyzed using frequency and cross analyses, and the statistical significance level was set at 0.05. Results: It was found that higher the economic and educational level, better was the subjective oral health, lower the CPI, lower the experience of toothache, higher the frequency of toothbrush use, lower the number of people having chewing problems, and higher the frequency of oral checkups. Conclusions: Oral health inequality exists among social classes. It is suggested that continuous research and efforts be carried out to promote oral health while considering socioeconomic and educational levels. Further, active government efforts will be needed to address polarization by social class.

Objectives: The aim of this study was to investigate the number of existing permanent teeth and the denture usage status in elderly adults aged 65 years and above living in metropolitan cities and to confirm the degree of oral health inequality caused by the differences in oral conditions in each metropolitan city using the Lorenz curve and the Gini coefficient. Methods: The raw data for the analysis were obtained from the dataset of the sixth Korea National Health and Nutrition Examination Survey conducted between 2013 and 2015. The subjects included 1,764 people who underwent oral examination and answered questions. The complex samples general linear model was used to analyze the number of existing permanent teeth adjusted for age and monthly household income. The proportion of edentulousness and the denture status was analyzed using complex samples crosstabs. Results: The number of existing permanent teeth in the elderly adults aged 65 years and above was lowest in Ulsan (15.41) and highest in Gwangju (20.44). The proportion of edentulousness was highest in Busan (14.5%) and lowest in Daejeon (4.0%). With regard to the proportion of denture users, Busan had the highest tendency for denture usage (50.4%) and Gwangju had the lowest tendency (34.9) (p=0.172). The Gini's coefficient for the number of existing teeth was lowest in Busan (0.332). Oral health inequality was most severe in metropolitan cities. Conclusions: We found that oral health inequality exists among elderly adults living in the metropolitan cities of Korea using the Lorenz curve and Gini's coefficient.
