The age range associated with the reported DMFT and DMFS values is?

Explanation:
DMFT and DMFS measure caries experience in the permanent dentition, so they’re most informative during the period when permanent teeth have erupted and can be reliably assessed in a broad group of children. In public health dentistry, this leads to reporting these indices for school-age populations, typically 5–17 years old, which provides a standardized window for comparison across studies and populations. In younger children (0–4), primary teeth predominate and a different index (dmft) is used, while older adults are usually analyzed with age-specific adult ranges. That’s why the associated age range for DMFT/DMFS values is 5–17 years.
