Summary
Removable dentures may negatively impact swallowing function, particularly oral transit time (OTT) and oropharyngeal swallow efficiency (OPSE). Removing dentures improved these measures, suggesting a link to oral sensation and chewing ability.
Area of Science:
- Gerontology
- Speech and Hearing Science
- Biomedical Engineering
Background:
- Removable dentures are common among elderly populations.
- Swallowing difficulties (dysphagia) can lead to serious health complications.
- The impact of removable dentures on swallowing function requires further investigation.
Purpose of the Study:
- To investigate the relationship between removable dentures and swallowing function.
- To identify potential risks associated with removable denture use.
- To evaluate changes in swallowing parameters before and after denture removal.
Main Methods:
- Videofluoroscopic swallowing study (VFSS) was used to assess swallowing in 24 patients with removable dentures.
- Swallowing function was evaluated with and without dentures.
- Masticatory performance, oral sensation, and neurological status were also assessed.
Main Results:
- Significant reduction in oral transit time (OTT) after denture removal (8.87s vs. 4.38s).
- Oropharyngeal swallow efficiency (OPSE) showed a trend of improvement post-denture removal (18.24%/sec vs. 25.26%/sec).
- OTT and OPSE correlated with masticatory performance and oral sensation when wearing dentures.
Conclusions:
- Removable dentures may negatively affect swallowing, specifically OTT and OPSE.
- Impaired oral sensation and masticatory performance induced by dentures could be contributing factors.
- Denture use may pose risks for individuals with swallowing impairments.

01:11Oral Cavity
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

01:25Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

01:26Enteral Nutrition I: Orogastric and Nasogastric Feeding
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:23Salivary Glands and Saliva
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...
