Brief summary
Tooth loss impacts taste abilities and food intake. Present study aims at pertaining the impact of teeth loss and the replacement by means of complete denture on taste and trigeminal abilities, and on food preferences, and taste appetence.
Detailed description
Two groups of participants will be included. Participants wearing complete denture for at least one year (n=20) and their matched controls for age, sex, tobacco, and saliva secretion (n=20). Their oral sensory abilities of participants will be assessed including taste (electrogustometric thresholds, chemical taste identification ability) and trigeminal quantitative sensory testing. Food preferences and selectivity (Maitre et al., 2014) and taste appetence (Deglaire et al., 2012) will also be assessed.
