Correct answer: B — Neutral-pH artificial saliva spray

The correct answer is B. Artificial saliva substitutes are topical preparations used to provide temporary symptomatic relief by lubricating and moistening the oral tissues; they do not restore salivary gland function. A neutral-pH preparation is preferred in a dentate patient because acidic products may promote demineralisation. Hydrocortisone is used for appropriate inflammatory or ulcerative oral lesions, while miconazole treats oral candidosis; neither is indicated here. Chlorhexidine is an antiseptic rather than a saliva substitute. Fluoride varnish may help manage the increased caries risk associated with xerostomia, but it does not directly relieve the sensation of oral dryness.
