Caries experience in rural Victorian adolescents

Area of Science:

• Dental Public Health
• Pediatric Dentistry
• Epidemiology

Background:

• Adolescent oral health is crucial for overall well-being.
• Dental caries remains a significant public health issue globally.
• Understanding caries patterns in non-fluoridated rural areas is essential for targeted interventions.

Purpose of the Study:

• To assess the oral health status of adolescents in a non-fluoridated rural area.
• To identify factors influencing dental caries experience and unmet dental needs.
• To inform future public health strategies for adolescent oral care.

Main Methods:

• Cross-sectional survey of 818 adolescents aged 12-16 years.
• Data collection on dental caries experience (DMFS index), fissure sealant prevalence, and access to dental services.
• Statistical analysis to compare caries experience and unmet needs based on age and access to public dental services.

Main Results:

• Caries prevalence and severity increased with age, with occlusal surfaces most affected.
• Filled surfaces constituted the largest component of DMFS, indicating past caries experience.
• Fewer fissure sealants were observed with increasing age, and second molars were less frequently sealed than first molars.
• No significant difference in total caries experience between those with and without public dental service access.
• A statistically significant difference in unmet dental needs was found, with higher untreated caries in health card holders.

Conclusions:

• Age is a significant factor in the progression of dental caries among adolescents in this population.
• The high proportion of filled surfaces suggests a history of untreated caries.
• Targeted preventive and treatment services are a priority for vulnerable groups, including health card holders, to address unmet dental needs.
