Pulpotomy Procedure and Techniques

This video tutorial demonstrates a reliable method for performing a pulpotomy on a deciduous molar, followed by restoration with a preformed stainless steel crown. It covers the necessary materials, the importance of using a rubber dam, and the step-by-step process of accessing and removing caries, accessing the pulp chamber, achieving haemostasis, and filling the pulp chamber with zinc oxide eugenol material.

What is the primary purpose of using a rubber dam during a pulpotomy?

• To enhance the aesthetic appearance of the tooth

• To reduce the cost of materials

• To protect the airway and increase patient comfort

• To speed up the procedure

What should be done if the clamp fits well on the tooth?

• Fit the rubber dam

• Proceed with the pulpotomy

• Apply local anaesthetic

• Start the restoration process

Which tool is used to gain access to the caries?

• Slow handpiece with a rose head burr

• High-speed handpiece with a diamond fissure burr

• Rubber dam punch

• Excavator

What should be done if overhanging dentin is observed?

• Remove it to ensure access to the pulp chamber

• Leave it as it is

• Use it to support the restoration

• Cover it with a rubber dam

What indicates that the pulp is non-vital during the procedure?

• Overhanging dentin

• Difficulty in accessing the pulp chamber

• Absence of bleeding and necrotic appearance

• Presence of excessive bleeding

What is used to remove the coronal pulp?

• Rubber dam clamp

• Diamond fissure burr

• Large rose head burr or excavator

• Zinc oxide eugenol

What is the risk of overzealous preparation of the cavity floor?

• Inadequate haemostasis

• Longer procedure time

• Iatrogenic perforation

• Increased patient discomfort

What is the purpose of using ferric sulfate during the procedure?

• To remove caries

• To fill the pulp chamber

• To achieve haemostasis

• To disinfect the cavity

How long should ferric sulfate be left in contact with the pulpal tissue?

• 10 minutes

• 5 minutes

• 1 to 2 minutes

• 30 seconds

What material is used to fill the pulp chamber after haemostasis is achieved?

• Composite resin

• Amalgam

• Zinc oxide eugenol

• Glass ionomer
