Access preparation

What is the anatomy of the pulp chamber?

• The anatomy of the pulp chamber includes the pulp chamber and the root canals.

• The anatomy of the pulp chamber includes the nerves and muscles.

• The anatomy of the pulp chamber includes the ligaments and tendons.

• The anatomy of the pulp chamber includes the bones and skin.

What are the principles of design of the access cavity?

• Increase in healthy dental structure, preservation of carious tissue, indirect access to the pulp chamber

• Preservation of healthy dental structure, removal of carious tissue, creation of a direct access to the pulp chamber

• Restoration of healthy dental structure, removal of healthy tissue, creation of a complicated access to the pulp chamber

• Removal of healthy dental structure, preservation of carious tissue, creation of an oblique access to the pulp chamber

How is endodontic access performed in molars?

• Without anesthesia, opening of the dental crown, removal of the pulp tissue, preparation of the root canal.

• Local anesthesia, closure of the dental crown, removal of the pulp tissue, preparation of the root canal.

• Local anesthesia, opening of the dental crown, removal of the pulp tissue, preparation of the root canal.

• General anesthesia, opening of the dental crown, removal of the pulp tissue, preparation of the root canal.

What is the technique for access cavity in anterior teeth?

• Technique of U-shaped access

• Technique of L-shaped access

• Technique of C-shaped access

• Technique of T-shaped access

What considerations should be taken into account when preparing an access cavity in premolars?

• Dental anatomy, pulp location, extent of caries, and preservation of healthy structure.

• Type of restoration used

• Tooth color

• Number of roots

What is the ideal shape of the access cavity in molars?

• Square with sides towards occlusal and apical

• Triangular with the base towards occlusal and the vertex towards apical

• Trapezoidal with the base towards occlusal and the vertex towards apical

• Circular with the diameter towards occlusal and apical

Why is the localization and extension of the access cavity important?

• Why is the location and extent of the access cavity important?

• To reduce the effectiveness of endodontics

• To improve the patient's oral health

• It is important to ensure proper endodontic treatment.

• To increase the cost of treatment

What is the function of the access cavity in endodontic treatment?

• Allow access to the pulp chamber and root canals

• Help with food digestion

• Provide structural support to the tooth root

• Facilitate communication with the patient during treatment

What instruments are used to prepare an access cavity?

• Metal file

• Hammer and chisel

• Drill and wood bit

• Tungsten carbide round bur and diamond bur

What is the importance of irrigation during the preparation of the access cavity?

• The irrigation is important to clean and disinfect the area, remove remnants of pulp tissue, and facilitate the visualization of dental anatomy.

• The irrigation is only used to rinse the mouth after the preparation of the access cavity

• The irrigation can damage the dental structure during the preparation of the access cavity

• The irrigation is not necessary in the preparation of the access cavity
