What should you do if there is a sign of infected pulp in a case that has had avulsion with an open apex?

Apexification
Extraction
Filling
Root canal treatment

The correct answer is: Apexification

If there is a sign of infected pulp in a case that has had avulsion with an open apex, apexification is the preferred treatment option. This is because apexification helps in the formation of a barrier at the apex, promoting the growth of healthy tissue and preventing bacterial from entering the root canal. Extraction is not recommended as it would result in the loss of the tooth. Filling and root canal treatment are not the ideal options in this case because there is a risk of the infection spreading to the apex of the tooth.
