Atomic absorption spectrometric determination of cadmium and lead in human and artificial teeth by direct atomization technique.

A method of graphite furnace atomic absorption spectrometry (GFAAS) with a direct atomization technique has been developed for the determination of trace amounts of Cd and Pb in human teeth and artificial teeth. The samples were ground to a particle size of less than 10 microns and mixed with the same amount of graphite powder. One-half to 2 mg of mixed sample was weighed in a tared graphite cup and atomized in a cup-type graphite furnace according to the heating program that was established. Absorbances were determined by integration of the spectral lines in the absorbance vs time spectrum. Calibration was affected using aqueous standard solutions. The results for six human tooth samples and two artificial tooth samples were in good agreement with the values obtained by GFAAS for dissolved samples. The relative standard deviations were 3.1-12% (n = 10) for Cd (19-95 ng g-3) and 0.9-8.1% (n = 10) for Pb (1.43-6.32 micrograms g-3). The determination limits corresponding to twice the standard deviation (sigma, n = 10) for blank measurements were 13 pg for Cd and 53 pg for Pb.

Masticatory function - a review of the literature. III. Masticatory performance and efficiency.

A review and evaluation of the literature on mastication has been undertaken. Part I discusses the form of the masticatory cycle in the natural and artificial dentitions, including the controversial question of whether tooth contact occurs during function. Part II reviews the literature concerning the speed of movement of the mandible, rate of chewing, and the forces developed in chewing. Part III describes masticatory efficiency and performance, the effect of food on masticatory function, and incorporates a summary of all these three papers.
