Diode laser irradiation and fluoride uptake in human teeth.
AIM To evaluate chemically the effects of diode laser on fluoride uptake before and after laser irradiation of enamel surfaces. METHODS Crowns of 20 sound human teeth were halved and a 3 x 3 mm acid-resistant varnish uncovered window left for: A) no treatment; B) fluoride (Elmex gel); C) diode (fluoride + diode laser); D) diode (diode laser + fluoride). The dental surfaces were analysed using...
متن کاملFluoride concentration in dentin of exfoliated primary teeth as a biomarker for cumulative fluoride exposure.
A biomarker for lifetime fluoride exposure would facilitate population-based research and policy making but currently does not exist. This study examined the suitability of primary tooth dentin as a biomarker by comparing dentin fluoride concentration and fluoride exposures. Ninety-nine children's exfoliated primary teeth were collected from 2 fluoridated and 2 fluoride-deficient communities in...

15 صفحه اولForensic science and the analyst.
Forensic science has been slow to develop as a recognised field of study. Over the past 30 years, analytical and forensic science have developed together; though the application of new analytical techniques in forensic work is retarded by the necessity of having methods of proven reliability. The many techniques now applied in forensic analysis—microscopy, spectroscopy of all types, x-ray analy...
