The document discusses endodontic procedures and questions pertaining to carrying out pulpectomies, using instruments such as apex locators and endo stops, providing post-operative instructions to patients, and the roles of dental nurses during endodontic treatment. Reasons for endodontic procedures include relieving pain or pressure from diseased or injured pulp, and they allow saving a tooth rather than extracting it. Vitality tests, periapical radiographs, and irrigation solutions are used to diagnose the need for a pulpectomy and guide the endodontic treatment process.
