c) High-speed handpiece
d) Low-speed handpiece

Answer 1

In a pulpotomy of a primary tooth, a spoon excavator is typically used to remove the diseased pulp tissue efficiently and with precision.

Step-by-step explanation:

When performing a pulpotomy on a primary tooth, the dentist commonly uses a spoon excavator for removing pulp tissue. A pulpotomy is a dental procedure used to remove the diseased pulp tissue within the crown portion of a tooth. After administering local anesthesia, the dentist will access the pulp chamber and use the spoon excavator or sometimes a low-speed handpiece to gently remove the affected pulp. This instrument is essential as it allows for precise removal without damaging the surrounding tissues. Once the diseased pulp is removed, the area is disinfected, and a medicament is placed to preserve the remaining healthy pulp tissue and prevent bacterial growth. This treatment helps in maintaining the primary tooth until it's naturally time for it to exfoliate and be replaced by a permanent tooth.
