Abstract:
This study investigated the association between oral and general health-related behaviors and socioeconomic status, and the relationship between health-related behaviors and toothbrushing among adolescents. The database used here was the National School-Based Health Survey (PeNSE), a cross-sectional population-based study in 2009 with students from 27 Brazilian State capitals. Socio-demographic and health-related behavior data were collected. The survey included 49,189 adolescents (47.5% males), the majority of whom were 14 years of age and enrolled in public schools. The associations between toothbrushing frequency and other health-related behaviors and socioeconomic status varied between boys and girls. Associations were observed between health-related habits and toothbrushing frequency in both sexes, but with variations according to socioeconomic status. Planning health promotion interventions for adolescents should take their individual characteristics and family and social context into account.

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.
