Evaluation of methods based on evaluation of linear and/or volumetric dental measurements. When two values are given, they correspond to the metrics obtained in males/females. TCI, tooth coronal indexes; PLR, pulp linear ratio; PTLR, pulp-to-tooth linear ratio; PTAR, pulp-to-tooth area ratio; PTVR, pulp-to-tooth volume ratio; PV, pulp volume; PCLR, pulp-to-crown linear ratio; PCVR, pulp-to-crown volume ratio; PEVR, pulp-to-enamel volume ratio; PDVR, pulp-to-dentin volume ratio
