"It is primarily the result of a finite number of bacterial species within a complex biofilm on the subgingival surface of teeth." (Eley and Cox, 2000)
I can't help but think, "No, it really isn't". I can't be bothered going into why this statement is wrong in many ways, just take my word for it. This is what happens when dentists try to convince themselves that they are scientists.
In other news, I love archaic words which no-one uses anymore, but that they really should. Like fecundity, mucilaginous, and consortium. You folk are all smart - help me make a list of words to include (somewhere) in my thesis.
