1. A 30-year-old patient complains of spontaneous pain in a tooth with a formed cavity under the tab during a repeat visit. The pain appears a few hours after the preparation of the hard tissues of the tooth under the tab.

Your diagnosis? What are your patient management tactics?

2. When the cavity was localized on the distal surface of the molar, the doctor formed an additional cavity on the chewing surface. What functions does this cavity perform?

3. The patient complained that after restoring the defect of the crown part of the tooth with a plastic tab, she saw that a strip of cement was visible between the edge of the cavity and the tab.

Who made the mistake, what is it? Your tactics?
