Objective: This study aimed to investigate the factors associated with masticatory performance, as measured with a chewing gum containing spherical resinous microparticles, and to evaluate the method by examining the relationship with self-reported masticatory status. Methods: The participants in this study comprised 903 industrial workers (mean age, $42.2{\pm}11.6years$). A questionnaire was administered to assess self-reported masticatory status. The masticatory performance score was calculated by counting the number of particles in the chewing gum. Clinical oral examinations were administered. Multiple linear regression analysis was conducted on the masticatory performance scores to examine the related factors. Analysis of covariance was conducted to investigate the association between the masticatory performance score and the self-reported masticatory status. Results: Significant predictors of the masticatory performance score were sex (p<0.001), age (p<0.001), decayed teeth (p=0.009), total-functional tooth units (p<0.001), periodontitis (p=0.003), and malocclusion (p=0.011). The relationship between the masticatory performance score and the self-reported masticatory status was attenuated after controlling for confounding factors. Conclusion: The masticatory performance increased with age and decreased as the oral health status worsened. Using this chewing gum method partly, but not comprehensively, reflects masticatory performance. Therefore, various masticatory performance-related indexes should be employed to measure masticatory performance accurately.

Objectives: The purpose of this study was to investigate the influencing factors of removable dentures satisfaction in the elderly. Methods: A self-reported questionnaire was filled out by 256 elderly in Jeollanam-do from September 1, 2013 to June 30, 2014. The questionnaire consisted of general characteristics of the subjects, denture related characteristics systemic health characteristics and dental health behavior. Removable dentures satisfaction was adapted from Ban. The questionnaire for Removable dentures satisfaction included general treatment satisfaction, masticatory function satisfaction, denture retention satisfaction, aesthetic satisfaction measured by Likert 5 scale. Cronbach's alpha was 0.850 in the study. Data were analyzed for a t-test, one-way ANOVA and multiple regression analysis by using SPSS(SPSS 18.0, USA) program. Results: According to subjective and systemic health condition and oral health condition, there was a statistically significant increase in general satisfaction of treatment, masticatory satisfaction of function, denture satisfaction of retention, aesthetic satisfaction. The overall satisfaction for removable denture showed a significant improvement. In the multiple regression analysis, variation of removable denture satisfaction was positively associated with oral health status{good(b=0.736, p=0.000)}, denture treatment services{dental hospital clinic(b=0.327, p=0.023)}, and systemic health status{good(b=0.241, p=0.047)}. Conclusions: Satisfaction of removable dentures may have a positive impact on oral health condition, hospital type, and associated systemic disease. It is necessary to develop incremental care programs for oral health and systemic health and to make public opinion to encourage the program.

Objectives: The purpose of the study was to investigate the association between remaining functional teeth and oral health-related quality of life using Geriatric Oral Health Assessment Index(GOHAI) in the elderly. Methods: A self-reported questionnaire was completed by 237 female elderly in Daegu from May to September, 2015. The questionnaire consisted of general characteristics of the subjects and Geriatric Oral Health Assessment Index(GOHAI). A total of 216 female elderly data were analyzed for oral health status and their GOHAI score. Data were analyzed using SPSS 23.0 version. Logistic regression analysis showed the association of functional teeth and GOHAI score. Results: Number of functional teeth can affect oral health related quality of life in the elderly. When functional teeth is small, the odds ratio(OR) was 2.119(95% CI: 1.215-3.696). After adjusting age, residence type and education, OR was 1.900(95% CI: 1.060-3.399). Policies to preserve natural tooth should be recommended for increasing quality of life in general. Conclusions: This study showed significant association between number of functional teeth and the GOHAI score of the elderly women.
