Fluoridation in Canberra. III. Dental caries after ten years
Australian Dental Journal
|October 1, 1976
Abstract:
The water supply of Canberra was fluoridated in eptember 1964. This report covers the period 1965 to 1974 during which children aged five to twelve years were examined. These children had lived in Canberra since fluoridation commenced. In comparison with base-line data the results showed a progressive improvement in the DMF and defindices. The reduction in the DMF index for children aged six years who were examined in 1974 was 81.0 per cent, and for children aged twelve years it was 48.5 per cent. The reduction was greatest for incisor teeth.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
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...

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.
