Summary

Dental caries in Australian children has significantly declined, though high-risk individuals require targeted prevention. Adult caries remain prevalent, emphasizing the need for ongoing adult preventive strategies.

Area of Science:

  • Oral health epidemiology
  • Dental public health

Background:

  • The prevalence of dental caries (tooth decay) in Australian children has decreased significantly since the mid-20th century.
  • Despite overall decline, a small but significant proportion of children remain at high risk for caries.
  • Caries experience in adults, however, remains widespread and extensive, affecting the majority of teeth in dentate adults.

Purpose of the Study:

  • To analyze trends in dental caries prevalence and experience in Australian children and adults.
  • To identify shifts in caries management strategies and their impact on tooth retention.
  • To underscore the ongoing need for caries prevention and management programs.

Main Methods:

  • Analysis of historical and current data on caries prevalence and experience in Australian populations.
  • Examination of changes in dental treatment patterns, including fillings and extractions.
  • Assessment of tooth retention rates and edentulism trends.

Main Results:

  • Over half of Australian children now have no caries experience, but approximately 6% are high-risk.
  • Adult caries experience is extensive, with most teeth in dentate adults affected.
  • While overall caries prevalence in adults hasn't changed substantially, there's an increase in filled teeth and a decrease in missing teeth, indicating better tooth retention.

Conclusions:

  • Targeted high-risk strategies are needed for children with significant caries experience.
  • Increased tooth retention in adults highlights a growing pool of teeth at risk, necessitating continued preventive measures.
  • The focus of adult caries management has shifted towards maintenance and repair, underscoring the importance of lifelong prevention.
