The Influence of Age and Oral Health on Taste Perception in Older Adults: A Case-Control Study

Declining gustatory function, nutrition, and oral health are important elements of health in older adults that can affect the aging process. The aim of the present work was to investigate the effect of age and oral status on taste discrimination in two different groups of elderly subjects living eit...

The aim of the present work was to investigate the effect of age and oral status on taste discrimination in two different groups of elderly subjects living either in an Italian residential institution (TG) or in the community (CG). A total of 90 subjects were enrolled in the study (58 CG vs. 32 TG). Masticatory performance (MP) was assessed using the two-color mixing ability test. Taste function was evaluated using cotton pads soaked with six taste stimuli (salty, acid, sweet, bitter, fat and water). A positive correlation between age and missing teeth (r = 0.51, C.I. [0.33; 0.65], <i>p</i> < 0.0001), and a negative correlation between age and MP (r = −0.39, C.I. [−0.56; −0.20], <i>p</i> < 0.001) were found. Moreover, significant differences for salty taste, between TG and CG were detected (<i>p</i> < 0.05). Significant differences in bitter taste sensitivity between subjects wearing removable and non-removable prosthesis were also determined (<i>p</i> < 0.05). In addition, significant gender differences and between males in TG and CG were identified (<i>p</i> < 0.05). The best understanding of the relationship between MP, taste sensitivity, and nutritional factors is a necessary criterion for the development of new therapeutic strategies to address more effectively the problems associated with malnutrition in elderly subjects.Sonila AliaLuca AquilantiSofia PugnaloniAlice Di PaoloGiorgio RappelliArianna VigniniMDPI AGarticlenutritional statustaste perceptionoral healthmasticatory performanceNutrition.
