Abstract:
It has been carried out an inquest in a geriatric group in institutionalised regime, classifying people interviewed depending on dental health in three groups: Group I: Edentate ancients bearers of total prosthesis. Group II: Ancients with remanent pieces. Group III: Ancients with remanent pieces and bearers of prosthesis. In the present work, all findings related to oral health are detailed, referred uniquely to group II: "Ancients with permanent pieces". Obtained data let us get to some conclusions we consider must be of general diffusion for trying to understand and to solve the existing disputable in this segment of the population, so long forgotten and marginal.

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
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...
Tooth Anatomy
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.

The inspection begins with visually examining the mouth for symmetry, color, and size.
