Purpose: The purposes of this study were to assess the trend of use of statistical methods including parametric and nonparametric methods and to evaluate the use of complex statistical methodology in recent periodontal studies. Methods: This study analyzed 123 articles published in the Journal of Periodontal & Implant Science (JPIS) between 2010 and 2014. Frequencies and percentages were calculated according to the number of statistical methods used, the type of statistical method applied, and the type of statistical software used. Results: Most of the published articles considered (64.4%) used statistical methods. Since 2011, the percentage of JPIS articles using statistics has increased. On the basis of multiple counting, we found that the percentage of studies in JPIS using parametric methods was 61.1%. Further, complex statistical methods were applied in only 6 of the published studies (5.0%), and nonparametric statistical methods were applied in 77 of the published studies (38.9% of a total of 198 studies considered). Conclusions: We found an increasing trend towards the application of statistical methods and nonparametric methods in recent periodontal studies and thus, concluded that increased use of complex statistical methodology might be preferred by the researchers in the fields of study covered by JPIS.

Objectives: This study aimed to investigate the relationship between sleep quality and periodontal disease-related symptoms among Korean adolescents. Methods: This cross-sectional study was based on the 16th Korea Youth Risk Behavior Web-Based Survey (2020). A complex sample logistic regression was performed to identify the relationship between sleep quality and periodontal disease-related symptoms after adjusting for all covariates. Results: In model II, to estimate the adjusted odds ratio (AOR) for all covariates, students who answered "not at all sufficient", indicating sleep quality, were at higher risk of experiencing periodontal disease-related symptoms than those who answered "completely sufficient" (AOR=1.58). As a result of subgroup analysis, for estimating the AOR adjusted for all covariates in boys, students who answered "not at all sufficient", indicating sleep quality, were at a higher risk of experiencing periodontal disease-related symptoms than those who answered "completely sufficient" (AOR=1.68). In girls, students who answered "not at all sufficient", indicating sleep quality, were at a higher risk of experiencing periodontal disease-related symptoms than those who answered "completely sufficient" (AOR=1.43). Conclusions: It is necessary to formulate health policies that can promote optimal sleeping habits and oral health behaviors among Korean adolescents.

Objectives: This study aimed to examine the effects of dietary protein intake and quality on periodontal disease in Korean adults. Methods: The data used for analysis were obtained from the 7th Korean National Health and Nutrition Examination Survey (2016-2018). Data were analyzed using chi-square and t-test. Additionally, multiple logistic regression analysis was performed to assess the association between dietary protein intake and quality and periodontal disease. Statistical significance level was set at <0.05. Results: Multiple logistic regression analysis of dietary protein intake and periodontal disease in the model adjusted for socioeconomic factors showed that were significantly related to the Q1 (odds ratio [OR]: 1.18, 95% confidence interval [CI]: 1.01-1.39). However, this correlation was not significant in the model in which all variables were corrected. Moreover, analysis of the dietary protein quality and periodontal disease in model 4, which was adjusted for socioeconomic variables, showed that were significantly related to the low score (OR: 1.13, 95% CI: 1.00-1.27). Conclusions: The results showed a significant association between periodontal disease and poor intake and quality of dietary protein in the Korean adult population.

This study was conducted on industrial workers to develop an integrated health promotion program on chronic disease and oral health, and to provide basic data for an effective management plan by conducting comparison analysis of periodontal health status based on the findings of hypertension and diabetes disease, and by understanding of influencing factors on periodontal health status. And the study was conducted on 4,600 workers in certain areas from March 22, 2010 to June 18, 2010. The results of the study indicates significant difference by having high plaque and gingivitis ratio in the people who had the findings of hypertension and having high plaque ratio in the people who had the findings of diabetes disease. Regarding the influences on periodontal health status, gender, age, whether the subject visited a dental hospital, whether the subject had scaling treatment, smoking, and hypertension had influenced gingivitis. And gender, age, whether the subject visited a dental hospital, whether the subject had scaling treatment, smoking, and hypertension had influenced plaque. And the aforementioned 2 groups had statistically significant difference, and the conclusion is established that metabolic syndrome which is measured during the health exam of workers is an important disease potentially threatening the health of workers and also highly related to oral health.

본 연구는 중년의 건강실천행위가 치주상태를 매개하여 우울을 예측할 수 있는지를 알아보기 위해 시행하였다. 2015년도 국민건강영양조사 데이터를 활용하여 만 45세에서 64세 총 2,064명의 중년을 연구대상으로 하였으며, SPSS 24.0와 SPSS PROCESS macro를 이용하여 자료 분석을 하였다. 그 결과, 중년의 성별에 따른 조사결과 우울은 여성(0.15)이 남성(0.10)보다 높게 나타났다. 동거유형에 따른 조사에서는 1인가구주의 건강실천행위(3.92)가 가장 낮았으며 우울(0.25) 및 치주상태(1.76)는 가장 높은 것으로 조사되었다. PROCESS macro에 의한 매개효과 검증결과, 치주상태는 건강실천행위와 우울의 관계에서 매개효과가 있는 것으로 나타났다(${\beta}=-0.0180$, BCCI [-0.0353~-0.0042]). 이러한 결과는 치주상태가 중년의 우울증에 밀접하게 연관되어 있으며, 향후 중년층을 대상으로 하는 정신건강증진프로그램 개발을 위한 기초자료로 활용될 수 있으리라 생각된다.

본 연구의 목적은 건강 생활양식과 치주치료필요와의 관련성을 알아보기 제5기(2010, 2012년) 국민건강영양조사자료 중 만 19세 이상의 성인 11,488명을 분석자료로 사용하였다. 조사대상자의 일반적 특성과 건강 생활양식에 따른 치주치료필요자를 비교하기 위하여 카이제곱 검정을 실시하였고, 치주치료필요에 영향을 미치는 변수를 확인하기 위하여 로지스틱 회귀분석을 실시하였다. 연구결과 조사대상자의 일반적 특성 중 구강검진을 안 한 사람이 77.2%로 높은 비중을 차지하였으며, 치실, 치간칫솔 등의 구강위생용품 사용은 24.9%에 불과하였다. 일반적 특성 및 건강관련 생활양식에 따른 치주치료필요 여부 차이를 검증한 결과 읍/면에 거주하는 경우 치주요양필요가 높은 것으로 조사되었으며(p<0.01), 여성보다 남성에서 치주치료필요가 높게 나타났다. 연령 증가에 따라서 치주치료 필요가 증가하는 경향을 보였으며(p<0.01), 소득수준과 교육수준이 높은 경우, 비흡연자의 경우, 칫솔질 횟수가 증가하는 경우, 구강위생용품을 사용하는 경우, 구강검진을 안 하는 경우 치주치료필요가 감소하는 것으로 나타났다(p<0.01). 치주치료필요에 영향을 미치는 변수로는 거주지, 성별, 교육수준, 비만 여부, 구강검진 유무 등으로 조사되었다(p<0.01). 이와 같은 결과를 토대로 볼 때 건강관련 생활양식은 구강건강상태에 영향을 미치는 중요 변수로 생각되며, 전문 치과위생사는 국민의 구강건강을 증진시키기 위해서는 건강한 생활양식을 습관화할 수 있는 실천프로그램을 체계적으로 제공해 줄 필요성이 있다. 또한 몇 가지 건강행위와 인구사회학적 변수로는 설명력이 낮기 때문에 보다 건강과 관련된 위험요인들을 포함한 구강건강생활양식을 측정할 수 있는 도구개발이 필요하다고 생각된다.
