Global dental caries (tooth decay) prevalence varies widely, with high rates in many countries. Sociodemographic factors significantly influence caries distribution across all age groups, necessitating global oral healthcare reform.
Area of Science:
- Oral Health Epidemiology
- Global Public Health
- Dental Caries Research
Background:
- Dental caries remains a significant global health issue with highly variable prevalence.
- Understanding the distribution and sociodemographic drivers of caries is crucial for effective public health interventions.
- Existing data show disparities in caries prevalence across different age groups and geographic regions.
Purpose of the Study:
- To summarize global clinical data on coronal caries distribution and its sociodemographic drivers.
- To analyze caries prevalence by age and mean number of affected teeth in children, adults, and older populations.
- To identify patterns linking sociodemographic indicators to caries data for healthcare system reform.
Main Methods:
- Review and synthesis of existing clinical data on coronal caries distribution worldwide.
- Analysis of global caries prevalence, stratified by age groups (children, adults, older persons).
- Examination of sociodemographic, ethnic, cultural, geographic, and lifestyle factors influencing caries.
Main Results:
- Global caries prevalence exhibits extreme variation, with persistently high rates in numerous countries.
- Caries prevalence shows decreasing trends in Western children and adults but remains skewed by individual/community factors.
- Older adults exhibit very high caries prevalence (up to 98%), with heterogeneous distribution; tooth loss shows a declining trend.
Conclusions:
- Significant inequalities in caries prevalence necessitate a life-course approach and reform of global oral healthcare systems.
- There is a critical need for primary oral health data to support evidence-based national oral healthcare policies.
- Addressing sociodemographic disparities is essential for reducing the global burden of dental caries.

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...

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...
