Randomized trial evaluates age estimation in cremated remains using tooth cementum analysis, suggesting promising methods.

Evaluate the methodological applicability of tooth cementum annulation counts in estimating age at death from cremated remains.
Analyzed 62 roots from eight cemeteries of the Lusatian Urnfield culture in Poland.
Prepared undecalcified transverse sections and examined incremental lines alongside complementary indicators.
Evaluated intra- and inter-observer repeatability and age-related increases in tooth cementum parameters.
ILSc showed good intra- and inter-observer repeatability (p < 0.01).
Age-related increases in AEFCt and ILSc were significant (p < 0.01).
Combined estimates from TCAc and AEFCt/ILSw produced narrower age ranges compared to morphological analysis alone.

Hałuszko et al. (2026) studied this question.
