Effects of age and dentition status on measures of food acceptability

The current cross-sectional investigation was undertaken to determine whether observed losses in masticatory function due to missing teeth impair perceptual estimates of food acceptability. To quantify the effect of impaired masticatory ability, 566 male participants from the Veterans Administration Dental Longitudinal Study were subdivided into three age groups (less than 40 years, 40 to 49 years, and 50 or more years) and three dentition categories (intact, partially compromised, and compromised). Bivariate analysis revealed that dentition status significantly influenced the acceptance modalities of taste, texture, perceived ease of chewing, and frequency of ingestion. Age, per se, had little effect. Significant changes in the acceptance variables were noted only in persons with compromised dentition. These findings suggested that a moderate degree of unreplaced tooth loss had no significant effect on perceptual estimates of food acceptability, and unilateral intact dentition can provide sufficient masticatory performance for maintaining food acceptance.
