Final answer:
Zinc oxide eugenol cement is recommended to temporarily seat a fixed bridge to decrease abutment tooth sensitivity, due to its soothing effect on the pulp.
Step-by-step explanation:
To decrease abutment tooth sensitivity, a fixed bridge may be temporarily seated using zinc oxide eugenol cement. This type of cement has a soothing effect on the pulp and is known for its palliative effect on sensitive teeth. Other materials, such as strontium chloride or potassium nitrate, can be included in toothpaste formulations to target sensitivity. Additionally, toothpastes containing arginine and calcium sodium phosphosilicate (CSPS) have been proven effective for alleviating dentinal hypersensitivity. Periodontitis is a serious gum condition that could exacerbate tooth sensitivity. To treat this, cleaning, dental hygiene, and potentially antibiotics such as tetracycline, doxycycline, macrolides, or ß-lactams may be necessary.
