Determination of levels of some trace elements in teeth samples in Al-Najaf Governorate, Iraq

Abstract

Essential biological elements are found in trace amounts in both the human and animal bodies. Thus, altering their levels can have serious negative effects, such as poisoning. This study evaluated 40 teeth samples from healthy men and women. Mg, Al, and Fe had significantly more trace element contents in teeth samples than did K and Zn, according to research using X-ray photoelectron spectroscopy (XRF). Teeth levels showed no statistical significance when compared with the mean and concentration of a healthy individual sample, for which a P-value (P>0.05) was found. However, a correlation was found between iron and aluminum in teeth samples. The number of teeth tools available may be an important factor in the causes of teeth decay.
