Evaluation of some factors affecting taste perception

The sense of taste is one of the most important human senses. Alteration in taste perception is crucial because it influences dietary habits and general health. In this study, we evaluated the influences of some physiological and external factors on taste perception such as gender, smoking, dietary habits and role of saliva in a group of young people. Twenty young subjects (mean age 25.2) were enrolled for the study. A whole-mouth, above threshold test and a spatial taste test were performed using four basic tastes (sweet, salty, sour, bitter). There was no significant difference in taste threshold concerning gender (p > 0.10), but a significant relation was found between the number of cigarettes per day and an increase in threshold for sweet taste (p<0.10). There was a significant relation between the frequency of salty food consumption and increase in threshold for bitter taste (p < 0.10). No significant difference was found between wet and dry mouth in spatial test (p > 0.10). This study suggests further researches, investigating various factors influencing taste perception
