Final answer:
Teeth that need to be removed in a patient scheduled for radiation therapy for tongue carcinoma should be extracted before the radiation therapy begins to minimize the risk of complications like osteoradionecrosis.
Step-by-step explanation:
If removal of teeth is indicated in a patient who is to receive radiation therapy for a carcinoma of the tongue, the teeth should be extracted prior to the radiation therapy. This is because the radiation can reduce blood flow to the jaw, leading to a condition known as osteoradionecrosis (ORN), which can complicate healing after extractions. Removing the teeth before radiation therapy minimizes this risk and also decreases the chance of infection, as the immune system can be compromised by the radiation.
It is important to allow enough time for healing from the extractions before beginning radiation therapy. Clinicians typically recommend a healing period of at least 14 days, but this can vary depending on the patient's overall health and other factors.
Maintaining oral health during and after radiation therapy is crucial as well. Medications and treatments, such as special mouthwashes, are available to manage radiation therapy side effects, like dry mouth or nausea, ensuring the patient's comfort and reducing the risk of complications.
