Answer 1

The status of a tooth with a metal-ceramic crown is determined by radiographic appearance, response to percussion and palpation, and history and subjective symptoms, making the correct answer (a), (c), and (d).

Step-by-step explanation:

The status of a tooth with a metal-ceramic crown can be determined by various methods, including radiographic appearance, the tooth's response to an electric pulp tester, its response to percussion and palpation, and the patient's history and subjective symptoms. Radiographs (X-rays) are particularly useful for assessing the extent of any decay that might not be visible externally, and the integrity of the structures surrounding the pulp cavity. Electric pulp testing can indicate whether the tooth's pulp is still vital by measuring the response to an electrical stimulus. Response to percussion and palpation can help determine whether there is inflammation or infection in the periapical tissues, and the patient's history and subjective symptoms can provide indications of the tooth's condition over time. Therefore, the correct answer would be (a), (c), and (d) - radiographic appearance, response to percussion and palpation, and history and subjective symptoms.
