But they're clearly a large factor in tooth decay, so measuring the contents of various liquids and comparing them to each other is instructive.

What's the role of saliva? of bacteria? of genetics? Don't underestimate the power of the telephone game (http://en.wikipedia.org/wiki/Chinese_whispers http://en.wikipedia.org/wiki/Chinese_whispers). You need to go back to primary sources. It's very common for papers in software engineering, for instance, to confuse qualitative statements from earlier papers with empirical results.
