A prospective observational study of the impact of wearing dentures on swallowing function - A prospective observational study of the impact of wearing dentures on swallowing function

The mean age of the 27 participants was 86.1 (6.8) years. The vallecular residue was more in those without dentures (with dentures: 0.01 [0 - 0.02], without dentures: 0.03 [0 - 0.08]; P = 0.003). The pyriform sinus residue showed no significant difference. Denture removal significantly increased the pharyngeal area. The distance between the maxilla and mandible decreased in the absence of dentures. Oral/pharyngeal transit time was prolonged without dentures.
