Objectives: This study aimed to analyze the correlation between oral function, oral environment, and brain cognitive function in the elderly. Methods: The subjects were 60 users of senior community center and elderly day care center. The survey was conducted from November to December 2018. Subjects were assessed by oral examination and myofunction test. Oral myofunction was measured using $IOPI^R$ and Lip de $Cum^R$. Survey data were analyzed using the statistical programs of PASW Statistics ver. 18.0. Results: Tongue muscle strength and lips muscle strength was higher in males than in females. The tongue and lip strengths were higher in the <81 years old group than the ${\geq}81$ years old group. Functional tooth analysis showed that there was a ${\geq}15$ teeth group ($40.91{\pm}7.36$) and a <15 teeth group ($32.52{\pm}7.14$). Lip muscle strength analysis showed that the ${\geq}15$ teeth group ($10.54{\pm}3.40$) was higher than the <15 teeth group ($8.20{\pm}2.41$, p<0.05). Tongue muscle strength, lumbar muscle strength, and functional tooth number were lower in the elderly subjects with mild cognitive impairment. Cognitive function was significantly correlated with functional tooth number (r=0.386, p<0.001), tongue strength (r=0.478, p<0.001), and lip strength (r=0.281, p<0.05). Tongue strength was significantly correlated with lip strength (r=0.360, p<0.001) and functional tooth number (r=0.633, p<0.001). Lip strength was significantly correlated with functional tooth number (r=0.376, p<0.001). Conclusions: These results showed that age and functional tooth number influenced oral muscle strength and that the number of functional teeth and oral muscle strength were low in the elderly with mild cognitive impairment. Oral myofunction training and oral care program are suggested to improve the quality of life of the elderly.

본 연구는 전신질환 노인을 대상으로 구강근기능과 구강환경을 조사하고 노인 구강건강 증진안을 제언하고자 하였다. 2019년 4-6월 동안 65세 이상 전신질환 노인 64명을 대상으로 구강근력, 구강건강관련 삶의 질, 구강세균에 대해 조사하고, PASW Statistics ver 18.0을 이용하여 분석하였다. 전신질환 유병은 1개 43.8%, 2개 40.6%, 기능치아수는 18.6개였다. 나이는 기능치아수(r=-.384, p<.01), 혀근력(r=-.104, p<.001)과 부적 상관관계가 있었고, 혀근력과 구순근력은(r=.279, p<.05)과 정적 상관관계가 있었으며, 연령과 총세균수는(r=-.336, p<.01) 부적 상관관계, 기능치아수와 총세균수는(r=.551, p<.001) 정적 상관관계 그리고 전신질환 수와 총세균수는(r=.327, p<.01) 정적 상관관계로 나타났다. 노인 전신질환자의 구강근기능과 구강환경의 문제점을 토대로 노인 구강건강 증진안을 제언하는데 의미가 있었고 초고령 시대를 앞두고 있는 지금 구강건강 관련 삶의 질을 증진시키기 위한 실제적인 정책안이 요구되었다.

Background: Factors affecting oral function include tooth number, oral muscle strength, and oral diseases. This study aimed to investigate the relationship among oral environment, muscle, and microbiology. Methods: Fifty-six elderly individuals in a day care center were included in the study. The survey regarding tongue and lip muscle strength and oral microorganisms was conducted from November to December 2018. Results: Tongue and lip muscle strength were greater in men than women (p>0.05). Tongue muscle strength was greater in the ${\leq}80-year-old$ group ($34.94{\pm}9.85$) than the ${\geq}90-year-old$ group ($25.57{\pm}7.54$) (p<0.05). Tongue muscle strength and lip muscle strength were greater in the ${\geq}15$ functional teeth group ($34.08{\pm}9.31$ and $9.25{\pm}1.63$, respectively) than in the <15 functional teeth group ($28.08{\pm}7.53$ and $7.76{\pm}1.51$, respectively) (p<0.05). Age was significantly correlated with functional tooth number, denture use, and tongue muscle strength. The number of functional teeth was positively correlated with tongue muscle strength, lip muscle strength, and oral microorganisms. Denture use was negatively correlated with tongue and lip muscle strength. Tongue muscle strength was significantly correlated with lip muscle strength. The number of Eubacterium nodatum was higher in men than women. The number of Parvimonas micra and Enterococcus faecalis was higher in the groups with ${\geq}15$ functional teeth, denture use, and greater tongue and lip muscle strength. The number of Lactobacillus casei was higher in the group that uses dentures and with greater tongue strength. Conclusion: Oral microbiology is more important in oral environment and management than oral muscle function. The correlation between oral muscle and oral microorganism requires further study. Therefore, oral care training should be conducted to improve the oral care practice of elderly individuals, maintain oral health through oral care, and prevent the decrease in saliva secretion by aging.
