Reduction in flow of saliva is not generally seen in______________?
Correct answer: A. Patients suffering from parkinsonism
- A. Patients suffering from parkinsonism
- B. Patient undergoing radiation therapy
- C. Elderly diabetics
- D. Patients on phenothiazine drugs
Explanation
Parkinsonism itself is not classically a direct cause of reduced salivary flow, whereas head-and-neck radiation, phenothiazines and diabetes in older patients commonly contribute to xerostomia. Antiparkinsonian medicines can still cause dry mouth, so the wording refers to the disease rather than its treatment.
