Oral Cavity01:11

Oral Cavity

4.0K
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...

Teeth

2.3K
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Effect of Aging on Tissues

4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Salivary Glands and Saliva01:23

Salivary Glands and Saliva

3.3K
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,...

Assessment of the Mouth01:26

Assessment of the Mouth

1.5K
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.

Area of Science:

  • Gerontology
  • Dental Prosthetics
  • Nutrition Science

Background:

  • High prevalence of edentulism in elderly patients, often with inadequate dental prostheses.
  • Systemic diseases and polypharmacy in the elderly can negatively affect oral health.
  • A significant interaction exists between general medical condition and oral health, particularly chewing ability and nutritional status.

Purpose of the Study:

  • To highlight the impact of chewing ability on nutritional status in elderly individuals.
  • To discuss the role of improved dental prostheses and implant stabilization in enhancing oral function.
  • To emphasize the necessity of interdisciplinary collaboration for optimizing nutritional outcomes.

Main Methods:

  • Review of existing evidence on edentulism, dental prostheses, and nutritional status in the elderly.
  • Analysis of the relationship between chewing efficiency, bite force, and dietary habits.
  • Discussion of treatment strategies including functional prostheses and implant-supported restorations.

Main Results:

  • Complete denture wearers often exhibit significant oral disability, leading to poor dietary habits.
  • Improved maximum bite force and chewing efficiency are crucial for adequate nutrition.
  • Functional dental prostheses or implant-stabilized dentures can enhance chewing parameters.

Conclusions:

  • Optimizing chewing ability through advanced dental solutions is vital for elderly patients' nutritional well-being.
  • Addressing oral disability in edentulous patients requires a comprehensive approach.
  • Collaboration between dental professionals and nutritionists is essential for improving nutritional status in the elderly.
