Systematic review characterizes dental caries trends in Kerman province, highlighting a need for action on oral health.

This analysis aimed to characterize the trends in dental caries measured by dmft/DMFT indices across various age groups in Kerman province.
Conducted a systematic review and meta-analysis following PRISMA guidelines.
Included cross-sectional studies and national reports on dmft/DMFT from various sources.
Performed random-effects model analysis and quality assessments using the Newcastle–Ottawa Scale.
Pooled dmft was 3.55 for ages 3-6 years and 13.80 for adults aged 35-44 years.
A significant increasing trend in caries levels was found for ages 3-6 years (+0.21 units per year; p<0.001).
High heterogeneity was observed across all age groups (I² > 94%, p < 0.001).

Pourfard et al. (2026) studied this question.
