Final answer:

Cutting dentinal tubules and using zinc oxide-eugenol can cause postoperative pain.


Explanation:

Cutting dentinal tubules during a class II cavity preparation and restoration can lead to postoperative pain and sensitivity. Dentinal tubules contain nerve endings that, when exposed, can cause discomfort. Additionally, the use of zinc oxide-eugenol as a dental base can also contribute to postoperative pain due to its potential irritant effects on the pulp.
