    황수연 , 박정은 | 2022, 22(2) | pp.107~115 | number of Cited : 0
    Abstract PDF
    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.

    Factors associated with dental service utilization among older adults

    최혜숙 | 2022, 22(2) | pp.117~124 | number of Cited : 0
    Abstract PDF
    Objectives: It is crucial to detect and prevent oral problems early. Older adults, in particular, should go for regular dental checkups to maintain a healthy oral environment. This study identified the factors affecting regular dental examinations and unmet dental needs in older adults. Methods: This study analyzed 3,362 older adults aged 65 or over using the data from the 7th Korean National Health and Nutrition Examination Survey (KNHANES). Frequency analysis was performed on general characteristics. In addition, chi-square tests were done to determine differences in regular dental checkups and unmet dental needs according to general characteristics. Logistic regression analysis was performed on factors influencing regular dental checkups and unmet dental needs. Results: Factors influencing regular dental checkups were statistically significant according to residential areas, level of education, household income, and levels of physical activity ( <0.05). Factors influencing unmet dental needs were statistically significant according to residential areas, level of education, private medical insurance, and levels of dental pain ( <0.05). Conclusions: National level policy strategies should be implemented to improve the oral health of older adults. These strategies should encourage regular dental checkups to effectively lower the rate of unmet dental needs.

    Relationship between stress and halitosis in Korean adolescents

    이은선 , Kyung-Yi Do | 2022, 22(2) | pp.125~132 | number of Cited : 0
    Abstract PDF
    Objectives: The purpose of this study was to examine the relationship between stress and halitosis in a representative sample of Korean adolescents. Methods: This study was based on the 15th Korea Youth Risk Behavior Survey (2019). The final participation rate in the survey was 95.3%; 57,303 out of 60,100 (95.3%) adolescents aged 13–18 years were selected. Multiple logistic regression with complex samples was performed to identify the correlation between stress and halitosis. Stress level was classified as ‘very much’, ‘a little’, and ‘not much’ and halitosis was defined as the presence of an unpleasant odor in the oral cavity. Results: The prevalence of halitosis among students was 21.3%. As a result of multiple regression analysis, the ‘a little’ [odds ratio (OR); 1.39, 95% confidence interval (CI); 1.29-1.49] and ‘very much’ stress group (OR; 1.78, 95% CI; 1.66-1.90) exhibited significantly higher risk of halitosis than the ‘not much’ stress group. Conclusions: A significant correlation between stress and halitosis exists among Korean adolescents. Therefore, psychological factors such as stress should be considered in managing halitosis in adolescents.

    윤용하 , 이정화 , Hie-Jin Noh and 2 other persons | 2022, 22(2) | pp.133~142 | number of Cited : 0
    Abstract PDF
    Objectives: This study was conducted by clinical dentistry hygienists to develop knowledge measurement tools and evaluate knowledge necessary to cope with emergencies related to systemic diseases occurring in dentistry. Methods: Basic questions were developed on the six most frequently occurring diseases in the dental office: diabetes, syncope, respiratory disease, coronary artery disease, cerebrovascular disease, and epilepsy. Fifty-eight preliminary questions were composed in a survey format through expert validation. The survey was then conducted on 290 dental hygienists to verify the composition validity and reliability. Factor and reliability analyses were performed using the SPSS 23.0 program, and the correct answer rate for each question was calculated. Results: 49 items of a total of 13 factors were adopted as the final items for signs, symptoms, prevention and treatment of five diseases. The question with the highest percentage of correct answers for each question was “Slowly set up the unit chair when raising the patient”(97.9%) during the prevention of unconsciousness and question with the lowest correct answer rate was “soft substances such as cloth should be put in the mouth to prevent trauma while the seizure persists” (16.6%). Conclusions: A total of 49 questions have been developed as tools to measure the knowledge of dental hygienists’ first aid related to systemic diseases and it is expected that related curriculum can be operated or evaluated by using them.

    김창희 , 김정희 , 김형미 | 2022, 22(2) | pp.143~151 | number of Cited : 0
    Abstract PDF
    Objectives: This study investigates dropout intention and the structural relationship between the dental hygienist role and satisfaction with the study major perceived by dental hygiene students. Methods: A survey was conducted on 269 dental hygiene students. The survey items covered general characteristics, department choice motivation, the desirability of dental hygienist career, practice clinical experience, perception of dental hygienist role, satisfaction with study major, and dropout intention. Independent sample t-test, one-way ANOVA, Mann-Whitney U test, multiple linear regression analysis, and structural equation modeling were used for statistical analysis. Results: The dropout intention level of dental hygiene students was 2.4 out of 5.0. Satisfaction with study major partially mediates perception of dental hygienist role and dropout intention (direct effect=0.182, =0.024, indirect effect=-0.437, =0.010). Perception of dental hygienist role (β=-0.255, =0.010) and satisfaction with study major (β=-0.661, =0.010) showed a negative relationship with dropout intention. The factor most affecting dropout intention was satisfaction with study major. Dropout intention was high when selecting a major based on external motivations (β=-0.448, <0.001). Conclusions: Perception of dental hygienist role and satisfaction with study major directly or indirectly affect dropout intention. Therefore, improving satisfaction with study major and improving the perception of dental hygienists will help reduce dropout intention.
