Hypodermis

Hypodermis

The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

Teeth

Teeth

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 and...

Oral Cavity

Oral 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...

Assessment of the Mouth

Assessment 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.

Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...

The Oral Microbiota

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Summary

This summary is machine-generated.

Reduced chewing efficiency may increase body fat. This study found lower masticatory efficiency is linked to higher body mass index (BMI), suggesting a potential risk factor for obesity.

Area of Science:

Oral Health Science
Nutritional Science
Human Physiology

Background:

Body fat accumulation is a significant public health concern.
Masticatory function plays a role in nutrient intake and digestion.
Understanding the interplay between oral health and body composition is crucial.

Purpose of the Study:

To investigate the relationship between body fat and masticatory function.
To determine if masticatory parameters predict increased body fat.

Main Methods:

Cross-sectional study of 100 dentate/partially edentulous participants.
Body fat assessed via Body Mass Index (BMI).
Masticatory function evaluated using occlusal pairs, sieving method for efficiency and swallowing threshold, and a self-reported questionnaire.

Main Results:

Masticatory efficiency, ability, and swallowing threshold were significantly related to BMI.
Lower masticatory efficiency (OR=4.792) and older age (OR=1.048) predicted increased body fat.
Gender and chewing rate did not show a significant relationship with BMI.

Conclusions:

Individuals with reduced masticatory efficiency may be at higher risk of developing increased body fat.
Masticatory function is a potential factor influencing body weight regulation.
Further research into the mechanisms linking chewing ability and body fat is warranted.
