Abstract:
This study evaluated dental caries according to the presence of natural teeth and sociodemographic conditions of an elderly population in the state of São Paulo, Brazil. Examinations were performed according to the World Health Organization's guidelines. The sample of 1,192 elderly individuals aged 65 to 74 years was stratified according to the presence of teeth and the following variables: gender, race, age, city size and Human Development Index (HDI). The Mann Whitney and Kruskal Wallis tests were applied at a confidence level of 95% for analysis of results. In the total sample, 68.9% (n=822) were edentulous; the mean of present teeth was 3.5 and the DMFT was 30.2, being 28.5 of missing teeth. Among dentate individuals (n=370), the mean of present teeth was 11.3, the DMFT was 26.2 and the missing component accounted for 20.7 teeth. The differences observed in the evaluated conditions should be highlighted: the mean number of present teeth was higher among younger individuals (from 65 to 69 years) [12.1] and among those living in cities with high HDI [12.9]; the DMFT was lower among men [24.9] and non-Caucasians [25.1]. Based on these findings, it may be concluded that specific dental programs should be established, with emphasis on oral health promotion and dental caries control, as well as public health policies that may enhance the access to the services provided.

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.

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

Bone Disorders
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...
Oral Cavity
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...
