| contents | Lead absorption in impacted third molars Rocío García Juan C. Hernández Sara Espinosa Raúl Belmont Armando Báez Ciencias de la Tierra teeth third molars impacted molars teeth lead concentrations Lead levels in 56 whole impacted third molars of 15-28 years old people living in Mexico Citywere determined by graphite furnace atomic absorption spectrophotometry. Samples were classifiedby tooth position, age, and gender. Third molar concentrations showed a nearly lognormaldistribution, therefore a non-parametric statistic was applied to estimate if there weresignificant differences among the mentioned variables and lead concentration. The geometricmean concentration ( X g) for all third molars was 4.21 ± 1.74 µg g-1, having mandibular molarshigher concentrations ( X g = 4.53 ± 1.62 µg g-1) than maxillary molars ( X g = 3.87 ± 1.86 µg g-1),however, no significant differences were found between them. The molars of the oldest donors presented the highest lead geometric mean concentration ( X g = 5.81 µg g-1). Females´ molarshad higher levels than males´ molars, with no significant differences between them. 2002 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37018203 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.2 Vol.18 |
