Go easy on the Sprite
Like most parents I limit my children’s intake of fizzy drinks, not least because of the affect they can have on their teeth. This recent paper looked at how one popular make of drink affected the leaching of metal ions from gold alloys used in dentistry. Good to see that detailed research work is still being done on the longest used dental restoration material; gold.You can find out a lot more on the use of gold in dentistry in the journal Gold Bulletin here.

Dental filling safety
It appears there’s a lively debate going on in the US about the safety (or not) of amalgam-based dental fillings. You can read about it here.What caught my eye was a comment from one dentist that ‘…..Except for gold, all materials have small potential safety issues….’ The biocompatibility of gold in dental applications is certainly well documented including in these papers in the Gold Bulletin archive…….

ScienceDirect TOP25 Hottest Articles
The ScienceDirect portal’s TOP25 Hottest Articles is a useful summary of those research papers that have generated a good level of interest in the research community.
I often scan this list to identify worthwhile new research on gold and there is usually catalysis and nanotechnology papers in the Hottest list, not really surprising given that these topics have large followings. However, it wasn’t catalysis or nanotechnology that caught the eye in the most recent list. In the current list of top materials science papers I hadn’t expected to find a paper on a new gold dental alloy…… So,
even in this established industry where the metallurgy of the alloys is very well known there is scope for innovation that is highly thought of by fellow researchers.By the way, the current issue of Gold Bulletin also contains a gold-related dental alloy paper ‘The influence of the microstructure of high noble gold-platinum dental alloys on their corrosion and biocompatibility in vitro’ M. Colic, D. Stamenkovic, I. Anzel, G. Lojen, R. Rudolf, Gold Bull., 2009, 42, (1), 34-47
