Talk:Hydroxylapatite
From Wikipedia, the free encyclopedia
the international association of mineralogy strongly recommends the word hydroxylapatite rather than hydroxyapatite. I suggest this article is renamed to hydroxylapatite.

Should Hydroxyapatite be listed as an alternate name? Is it an older spelling? RJFJR 18:42, 22 September 2005 (UTC)
- I don't know about it being older but the alternate spelling is certainly in use in solid-state chemistry and quite a few of the medical articles I've read also call it Hydroxyapatite. If anyone can get a source for that recommendation then it's worth mentioning in the article IMHO --Edith The Hutt 16:10, 9 February 2006 (UTC)

- I think that this is a case of two different sciences using two different names for the same thing. The medical profession seems to se hydroxyapatite. On the other hand the offical name of the mineral is Hydroxylapatite per the dictate of the International Mineralogical Association, the governing body of Mineralogy. Kevmin 04:06, 10 June 2007 (UTC)
[edit] Tooth enamel use
The tooth enamel page says it's made of hydroxylapatite. Can someone add to this article why this substance isn't used for dental fillings? It would seem like a natural choice if the substance is identical. (I also asked this over at the dental fillings talk page, and that article would benefit from the answer to this question, if anyone knows.) Tempshill 06:30, 20 January 2006 (UTC)
- IIRC it's about 90% hydroxylapatite yes, I'd speculate it's got something to do with the difficulty of forming it and that HAp in tooth enamel has a pretty distinctive microstructure which is very difficult to reproduce. That and maybe the fact you want to replace dentin too, I'm not a dentist or a bio-materials engineer so I couldn't really comment on that aspect. --Edith The Hutt 16:10, 9 February 2006 (UTC)
