[Prevalence of dental caries in children in a basic health zone. 5 years later]

Objective:
To find the state of dental health among the school population five years after the first study, performed in 1991.
Design:
An epidemiological observation cross-sectional study.
Setting:
Primary Care.
Participants:
820 school-children coming from seven local schools and belonging to first (5-7 years old), fifth (9-12) and eighth (13-16) grade Primary Education in the academic year 1995-1996.
Measurements And Main Results:
A dentist checked the children, following WHO norms. The prevalence of caries was studied (95.86 at 6 years old). The CAOD Index rose from 1.22 in boys and 1.84 in girls in first grade to 13.94 in boys and 13.81 in girls in eighth grade. The CAOS rose from 1.55 in boys and 2.55 in girls in first grade to 19.98 in boys and 20.15 in girls in the eighth grade. The CEOD fell from 5.19 in boys and 5.69 in girls in first grade to 1.32 in boys and 0.97 in girls in eighth grade. The index of restoration of permanent teeth was 5.50% in boys and 9.85% in girls in the eighth grade. 40.97% of 13 or 14-year olds suffered tooth-ache. 40.32% of eighth-graders brushed their teeth occasionally.
Conclusions:
The indices of caries, which were higher than in other areas of Spain, remained the same or even increased slightly five years later, which makes it urgent to take preventive measures in the schools.

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.
