So the resistance of the thermistor changes with temperature.
With no information about the rest of the circuit, your question is pretty meaningless.

What I'd use to convert temperature into a usable reading (via a thermistor) is one of the most useful circuits out there: The voltage divider.
https://en.wikipedia.org/wiki/Voltage_divider

Lets say that our thermistor is Z2 and we use a reasonable sized resistor for Z1.

Then the voltage at Vout, which you could measure with a microcontroller or multimeter, would be
[eqn] V_{out} = \frac{Z2}{Z1 + Z2} V_{in} [/eqn]
The current going through the thermistor (and Z1) changes as well with temperature.

Back to your original question.
If you have a voltage source, and connected to either side of your thermistor, then yes the current going through the resistor would change with temperature (and of course your voltage source doesn't change, so the voltage across the thermistor would remain the same)
