Research was carried out to measure the changes of L-C-S (Labial-Closure-Strength) due to aging. Numbers of subjects were: 761 adults (20 to 59 yrs old) and 170 elderly (60 to 89 yrs old), total of 931 subjects. L-C-S is fully developed at the age of about 18-20yrs for both males and females. L-C-S was 14-16N for males and 10-12N for females. These numbers showed only slight change until 60, but after this age the strength declined gradually due to age. L-C-S of healthy adults, both males and females in every age group were 3-4N higher than adults with diseases.
