Step-by-step explanation:
The recommended procedure for a patient experiencing severe, throbbing pain in a mandibular premolar aggravated by heat, biting, and touching is to see the patient at the office and initiate endodontic treatment (Option B). Endodontic treatment involves the removal of the infected pulp inside the tooth and the sealing of the root canal to eliminate pain and prevent further infection. This procedure is typically performed by a dentist who specializes in endodontics.
In the case of severe pain, it is important to address the underlying cause of the pain rather than simply providing temporary relief with analgesics or sedatives. Prescribing an analgesic (Option D) or referring the patient to an endodontist (Option D) may be necessary in certain cases but given the severity of the patient's symptoms it is best to initiate endodontic treatment as soon as possible to provide immediate relief.
