“…When dentures are removed, the tip of the tongue protrudes and thus the upward movements of the hyoid and the anterior movements of the larynx occur more easily then when dentures were worn [17], and as a result of this change, the opening of the upper esophageal sphincter increases and swallowing duration shortened [18]. Decreases in swallowing durations of edentulous patients were observed when dentures were removed compared to when dentures were worn [19]. Declines in sensation of oral cavity due to denture wearing, instability due to improper denture wearing or changes in tongue movements caused delays in OTTs.…”

ObjectiveTo investigate the relationship between removable dentures and swallowing and describe risks.MethodsTwenty-four patients with removable dentures who were referred for videofluoroscopic swallowing study (VFSS) were enrolled. We evaluated the change of swallowing function using VFSS before and after the removal of the removable denture. The masticatory performance by Kazunori's method, sensation of oral cavity by Christian's method, underlying disease, and National Institutes of Health Stroke Scale for level of consciousness were collected. Functional dysphagia scales, including the oral transit time (OTT), pharyngeal transit time (PTT), percentage of oral residue, percentage of pharyngeal residue, oropharyngeal swallow efficiency (OPSE), and presence of aspiration were measured.ResultsFour patients dropped out and 20 patients were analyzed (stroke, 13 patients; pneumonia, 3 patients; and others, 4 patients). The mean age was 73.3±11.4 years. There were significant differences before and after the removal of the denture for the OTT. OTT was significantly less after the removal of the denture (8.87 vs. 4.38 seconds, p=0.01). OPSE increased remarkably after the removal of the denture, but without significance (18.24%/sec vs. 25.26%/sec, p=0.05). The OTT and OPSE, while donning a removable denture, were correlated with the masticatory performance (OTT, p=0.04; OPSE, p=0.003) and sensation of oral cavity (OTT, p=0.006; OPSE, p=0.007).ConclusionA removable denture may have negative effects on swallowing, especially OTT and OPSE. These affects may be caused by impaired sensation of the oral cavity or masticatory performance induced by the removable denture.

“…While some studies [34–36••, 38–40] have suggested that denture wearing had positive effects on swallowing function, conversely, one study [41] indicated that denture wearing may have negative effects on swallowing function, especially the oral transit time (OTT) and oropharyngeal swallow efficiency (OPSE). OTT is the time from the moment at which the major bolus in the oral cavity begins to move rearwards to the moment at which the front end of the bolus arrives at the point of crossing between the lower edge of mandibular ramus and the tongue base.…”

Oral health impacts systemic health. Therefore, oral care is an important consideration in maintaining quality of life (QOL). Previously, maintenance and improvement of oral hygiene was considered essential for achieving oral health. In addition to oral hygiene, oral care in terms of oral function is now considered to maintain QOL. Ingestion of exogenous nutrients via the oral cavity is fundamental to the function of all higher animals, not only human beings. Chewing and swallowing processes are critical for normal food intake, and adequate saliva supply and oral care to allow proper functioning of these processes are indispensable for maintaining QOL. In this review, we will summarize the relationship between chewing and swallowing and effects of saliva secretion on these functions, and discuss methods to maintain ingestion of exogenous nutrients and prevent swallowing problems, especially in elderly people.

“…The upper and lower dental arches and jawbone were thus missing, so it was difficult for the tongue to control the bolus without dentures in the oral cavity, 24 suggesting poor bolus formation and transportation during feeding. Yamamoto et al 12 also reported that the bolus was scattered in the oral cavity and pharynx, and the scattered pieces of the bolus thus reached the hypopharynx before swallowing occurred.…”

“…Furthermore, a physiological study revealed that the use of complete dentures has beneficial effects on swallowing. Wearing dentures could decrease the risk of laryngeal penetration (8), stabilise swallowing movements (9), stabilise tongue-palate contact (10), shorten or lengthen bolus transit (11,12) and improve bolus transport dynamics (13). However, most of previous studies focused on liquid swallowing, and there were few studies focused on swallowing during feeding and swallowing of solid food.…”

Wearing dentures and dysphagia are common in older individuals; however, it is still unknown how dentures affect oral and pharyngeal swallowing. The purpose of this study was to reveal the effects of wearing and removing dentures on oropharyngeal movements during pharyngeal swallowing in the feeding sequence of solid food. Participants were 25 edentulous volunteers (nine men, 16 women; mean age 76·2 years) who wore complete dentures. The test food was minced agar jelly containing barium sulphate. Subjects were instructed to feed and swallow the test food with or without dentures during observation using videofluorography. We quantitatively evaluated the range, distance and duration of oropharyngeal movements during pharyngeal swallowing. When dentures were absent, the range of mandible and hyoid movements were significantly expanded in the anterosuperior direction, and the range of laryngeal movement was significantly expanded in the anterior direction. Additionally, the posterior pharyngeal wall contraction and upper oesophageal sphincter opening significantly increased. In addition, the distances of the mandible, hyoid and laryngeal movements and the mandibular duration were significantly extended when dentures were absent. No significant differences were observed in the duration of movements of other organs between wearing and removing dentures. The hyoid bone, larynx, posterior pharyngeal wall and upper oesophageal sphincter do not change their duration of movements when dentures were removed but, rather, expand their range of movement. This might be a spatial change of oropharyngeal movement to avoid temporal changes in pharyngeal swallowing when dentures were absent in edentulous older individuals.
