Teeth as Indicators of Environmental Pollution with Lead

Human civilization and concomitant increase in industrial activity have gradually influenced in redistribution of many toxic metals form the earth’s crust to the surrounding environment resulting in exposure of human population. Among different toxic elements, heavy metals, lead in particular, have high prevalence in the environment. Understanding of lead toxicity has advanced substantially over the past three decades, and focus has shifted from high-dose effects in clinically symptomatic individuals to the consequences of exposure at lower doses that cause no symptoms, particularly in children and fetuses [1].
