Summary
Good occlusal function, including larger contact areas and higher bite force, is linked to better body composition and health in premenopausal Japanese women. Maintaining natural teeth without dentures may support this association.
Area of Science:
- Oral health and nutrition science
- Biomedical research
- Human physiology
Background:
- Occlusal function, the way teeth fit together and function during chewing, plays a role in nutrient intake.
- Body composition, including lean mass and fat mass, is a key indicator of overall health.
- Previous research has not extensively explored the link between occlusal function and body composition in healthy premenopausal women.
Purpose of the Study:
- To investigate the relationship between occlusal function and body composition in 108 healthy premenopausal Japanese women.
- To determine if factors like occlusal contact area, occlusal force, and denture use are associated with body composition metrics.
Main Methods:
- Occlusal function was assessed using pressure-sensitive sheets.
- Body composition, including fat mass, lean mass, and bone mineral content, was measured using dual-energy X-ray absorptiometry (DXA).
- Statistical analyses were performed, adjusting for age and height, and a 1-year follow-up was conducted.
Main Results:
- Women with larger occlusal contact areas had significantly higher lean mass and grip strength.
- A 1-year follow-up revealed greater weight changes in individuals with smaller occlusal contact areas or lower occlusal forces.
- Subjects with partial dentures exhibited significantly smaller occlusal contact areas and lower occlusal forces compared to those without dentures.
Conclusions:
- A larger occlusal contact area and higher occlusal force are associated with favorable body composition, including greater lean mass and grip strength.
- Maintaining natural dentition without dentures may be linked to better health indicators in premenopausal Japanese women.
- These findings suggest that optimizing occlusal function could be a factor in maintaining good health and body composition.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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.

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

01:30Assessment of Airway, Skin Color, and Use of Accessory Muscles
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
