Paper points inserted into the canal for drying the canal(s) should be left in the canal for ____ seconds.

Explanation:
Drying the canal with paper points relies on capillary action to remove moisture. Holding a point in the canal for about five seconds gives enough time for moisture to be drawn into the paper, leaving the canal sufficiently dry for obturation. If the point is left only for three or four seconds, moisture may remain; if you go longer than about six seconds, the point can become over-saturated or fibers may residualize in the canal. Use clean points and repeat as needed until the point comes out dry.
