The present work will highlight the experimental technique, elements expected in dental powder and conclusions therein. During the past decade medical research has demonstrated that this Hg is continuously released as vapor into mouth air; then it is inhaled, absorbed into body tissues, oxidized to ionic Hg, and finally covalently bound to cell proteins. Dental powder has been analyzed using conventional XRF and hand held XRF (HHXRF).The spectrum shows a large amount of Si, K, Ca and Zr in XRF and Al in HHXRF. The HHXRF has an advantage of showing Al which is a prominent element in dental powders. To obtain Al which is present in dental powders HHXRF is the preferred technique to conventional XRF. The present work will highlight the experimental technique, elements expected in dental powder and conclusions therein. |
