Laser Induced Breakdown

In this work, the elemental constituents of smoker and nonsmokerteeth samples of human were analyzed by Laser induced breakdownspectroscopy method (LIBS). Many elements have been detected inthe healthy teeth samples, the important once are Ca, P, Mg, Fe, Pband Na. Many differences were found between (female and male)teeth in Ca, P, Mg, Na and Pb contents. The concentrations of mosttoxic elements were found significantly in the smoker group. Themaximum concentrations of toxic elements such as Pb, Cd and Cowere found in older male age above 60 year. Also, it was found thatthe minimum concentrations of trace elements such as Ca, P and Naexist in this age group. From these results it is clear that the LIBStechnique is a powerful tool for fast identification of teeth problems.
