Summary
Force platforms may not reliably detect posture changes from dental occlusion. While vision significantly impacts posture, the link with mandibular position is weak, suggesting caution for gnathologists using this technology.
Area of Science:
- Biomechanical analysis
- Human posture and movement
- Dental occlusion and its systemic effects
Background:
- Force platforms are common tools for assessing posture-occlusion relationships.
- Understanding the interplay between dental occlusion and body posture is crucial for clinical practice.
Purpose of the Study:
- To determine if force platforms can detect postural modifications induced by dental occlusion.
- To investigate the influence of mandibular position and visual input on body posture.
Main Methods:
- 44 healthy volunteers participated in stabilometric tests under varying mandibular and visual conditions.
- Key parameters measured included sway area, sway velocity, and center of foot pressure displacement.
- Analysis of variance (ANOVA) was employed to assess the significance of different factors.
Main Results:
- Ocular afference significantly affected sway area and sway velocity.
- Mandibular position demonstrated only a minor influence on the sway area.
- A weak correlation was found between mandibular position and body posture in healthy individuals.
Conclusions:
- Vision plays a significant role in modulating body posture.
- Force platforms may lack the sensitivity to clearly detect the relationship between mandibular position and body posture.
- Gnathologists should exercise caution when altering therapeutic plans based solely on force platform data.
- Sway area appears to be the most sensitive parameter for assessing occlusion's impact on posture.

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.

01:21Tooth 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.
