Calcium phosphate (hydroxyapatite, Ca3[-PO4]2-xCa[OH]2)
What's with the hyphen in the middle and the 'x'? Help! Thanks very much!
If you need context, follow directions below:
1. Go to: http://www.circ.ahajournals.org/cgi/content/full/94/5/1175
2. Go to subsection labeled "Lesions of Atherosclerosis and Calcium Deposition"
3. The notation is in the beginning of the second paragraph.

That's not the forumula I'm familiar with for Hydroxyapatite.
Ca10(PO4)6(OH)2
Check out the wikipedia entry below.

HA is Ca5 (PO4)3 .OH
but due to some in-stoichiometry it's shown by x to show it in a range.... e.g. (1.8-2.3)
you can assume it as solid solution of calcium phosphate (Ca3(PO4)2) and calcium hydroxide (Ca(OH)2)

Its not a hyphen , its the minus sign.
