Objectives : The objective of this study was to investigate the relationship between the statusand necessity of dental prosthesis and mastication function in the Korean elderly. Methods : This study investigated 4,557 elderly people aged over 65 in the 5th Korea NationalHealth and Nutrition Examination Survey(2010-2012). Frequency analysis, χ2 test, and logisticregression analysis were used. Results : Those aged over 75 complained of greater discomfort in mastication function thanthose from 65 to 74, and it was statistically significant(p<0.001). Mastication discomfort was notso significant in those with higher education and higher income(p<0.001). Those who did notuse prosthesis tended to have better mastication function(p<0.001). Denture users complainedof mastication discomfort when they used it(p<0.001). Conclusions : This study verified the relationship between the discomfort in mastication andrelated factors, and will provide the basic data for the access to dental clinic services.

Objectives : The purpose of the study is to investigate the effects of bite force by genderand physical features. Methods : A self-reported questionnaire was filled out by 212 college students in Chungnamprovince from October to December, 2013. The questionnaire consisted of oral health condition. The bite force of the first molar teeth was measured. Results : Males showed the greater bite force than females(p<0.001). Those who hadtemporomandibular joint(TMJ) disorder suffered from mouth opening difficulty and weaker biteforce than those who had not(p<0.05). Those who had malocclusion showed weaker bite force(p<0.01). Those who had a habit of chewing gums tended to have greater bite force than thosewho had not(p<0.05). The bite force was correlated with height(r=0.309), weight(r=0.345), andBMI(r=0.249)(p<0.01). Conclusions : Males showed greater bite force than females. The temporomandibular joint(TMJ) disorder, subjective malocclusion, and eating habit also affected the bite force.
