Objectives: This study was designed to assess the effect of age on orofacial force generation. Study Design: Forty women participated in a cross-sectional design, with 10 in each age group from 20 to 39, 40 to 59, 60 to 79, and 80 to 100 years of age. Methods: Measures of force generation were obtained for the upper lip, lower lip, tongue, and jaw. Results: There were no statistical differences among age groups, probably because of large individual variability within groups. Trends indicated a decline, particularly after age 80 years. Conclusion: Although trends in the data suggest some decline in the function of orofacial structures with age, it is unlikely that these changes would noticeably affect functional communication.
