Relationship between the care index and mean dmft/DMFT

Area of Science:

• Pediatric Dentistry
• Dental Public Health
• Epidemiology

Background:

• The care index is a measure of dental treatment utilization.
• Mean decayed, missing, and filled teeth (dmft/DMFT) indicates dental caries prevalence.
• Understanding the relationship between care and disease is crucial for public health initiatives.

Purpose of the Study:

• To evaluate the association between the dental care index and mean dmft/DMFT in children aged 5, 12, and 14.
• To analyze this relationship across different populations.

Main Methods:

• Utilized data from studies coordinated by the British Association for the Study of Community Dentistry (BASCD).
• Calculated correlation coefficients and linear regression between the care index and mean dmft/DMFT for each age group.
• Included additional factors like dentist:population ratio for 5-year-olds in 1995/96.

Main Results:

• A significant negative correlation was observed between the care index and mean dmft/DMFT across all age groups.
• This indicates that as dental disease levels decrease, the care index tends to increase.
• The negative relationship persisted even after accounting for other demographic factors.

Conclusions:

• A strong inverse relationship exists between the dental care index and mean dmft/DMFT.
• Declining dental disease levels are associated with an increasing care index.
• Conversely, rising disease levels correlate with a falling care index.
