1. Which of the following is not objectives of endodontic access cavity preparation? a. In the course of access cavity preparation, the coronal caries should be fully removed before getting into the pulp. b.

Roof of the pulp chamber should be entirely removed.

Answer 1

The correct answer is:e. Roof of the pulp chamber should be entirely removed.Explanation:The objectives of endodontic access cavity preparation are:a. In the course of access cavity preparation, the coronal caries should be fully removed before getting into the pulp. - This is an objective, as removing coronal caries is necessary to access the pulp.b. Any harm to the intact dental tissues should be avoided to the greatest extent possible. - This is also an objective, as preserving as much of the intact dental tissue as possible is important.c. Only necrotic pulp tissue should be removed. - This is an objective, as removing only the necrotic (dead) pulp tissue is typically the goal.d. All canal orifices should be localized. - This is an objective, as locating all the canal orifices is crucial for proper treatment.e. Roof of the pulp chamber should be entirely removed. - This is not an objective. Removing the roof of the pulp chamber entirely is not necessary and could lead to excessive removal of healthy pulp tissue.Therefore, the correct answer is e.
