Summary
Child dental treatment has shifted due to declining caries, with fewer complex procedures and increased use of glass ionomer cements (GIC). This trend in Western Australia
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Dental Materials Science
Background:
- Child dental caries rates have declined globally, impacting treatment needs.
- The School Dental Service (SDS) in Western Australia (WA) has collected extensive data since 1980.
- Changes in restorative techniques and materials, like glass ionomer cements (GIC), are evident.
Purpose of the Study:
- To report on trends in children's dental health and treatment provided by the SDS in WA since 1980.
- To analyze the impact of declining caries on dental treatment complexity and material selection.
- To evaluate the efficiency and viability of a dental service primarily based on auxiliaries.
Main Methods:
- Analysis of caries experience data from a random sample of children enrolled in the SDS.
- Review of treatment records, including operative procedures and material usage, collated monthly.
- Examination of data for approximately 240,000 children over several decades.
Main Results:
- Caries experience has decreased across most age groups, with a slight increase in dmft for six-year-olds in 1992-1993.
- Operative dental treatments are less frequent compared to 1980.
- Glass ionomer cements (GIC) dominate deciduous tooth restorations, while amalgam is preferred for permanent teeth. Fissure sealant use peaked in 1988 and has since declined.
Conclusions:
- The decline in caries has simplified dental treatment and reduced costs for the SDS.
- The SDS in WA demonstrates the effectiveness and efficiency of a dental care model utilizing dental auxiliaries.
- The findings support the viability of public dental services adapting to changing oral health needs.

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.
