Sibling similarities in the tempo of human tooth mineralization.

摘要: Abstract The extent of tooth mineralization is a useful estimate child's physiological age; it reflects the rate at which child developing towards maturity. As not known to what degree dental age regulated by genotype, this investigation estimated familial resemblance in tempo mineralization. Panoramic radiographs children 185 sibships were scored for stages formation, and was calculated from sex-specific standards. Intraclass correlations computed maxillary mandibular canines, premolars, second molars, third molars. Correlations significantly different than zero all 10 teeth ranged 0.17 (SE = 0.06) molar 0.43 (SE = 0.05) premolar. increased when multiple used more comprehensively define each age. Using an unweighted average types yielded correlation 0.41 (SE = 0.05). It appears, then, that considerable proportion total variability tooth-mineralization can be attributed transmissible effects operating population under investigation.
