Bacterial growth and plaque formation are enhanced by a diet with frequent intake of retentive carbohydrates. Gingivitis is an irreversible change in the interdental papillary tissues.

Correct Answer: C

Rationale: The correct answer is C. The first statement is true; retentive carbohydrates promote bacterial growth and plaque formation. However, the second statement is false; gingivitis is not irreversible and is often reversible with proper care. Gingivitis is the inflammation of the gums due to plaque buildup and poor oral hygiene. With good oral hygiene practices and professional dental care, gingivitis can be reversed. The other choices are incorrect because gingivitis is not irreversible, making statement two false.

Correct Answer: A

Rationale: Both statements are true. Patients who wear dentures typically experience reduced masticatory efficiency. Mandibular implant-supported dentures are known to have positive effects on the clinical aspects of mastication and swallowing, significantly improving chewing function. Option A is correct because both statements align with these facts. Option B is incorrect as both statements are true. Option C is incorrect as the second statement is also true. Option D is incorrect as the first statement is true.

Correct Answer: D

Rationale: During nutritional counseling, the most important step is to include the patient in the formulation of the dietary plan. This ensures their active involvement, understanding, and commitment to the plan, leading to better compliance and success in achieving nutritional goals. Consulting the patient's family (Choice A) may be helpful but should not replace involving the patient directly. Formulating a sample diet plan before presenting it to the patient (Choice B) may not align with the patient's preferences or needs. Including members of the dental team in the dietary formulation (Choice C) may not be necessary unless specific dental concerns need to be addressed.

Correct Answer: A

Rationale: The correct answer is A: Hypertension. The DASH diet is specifically designed to control hypertension by reducing sodium intake, managing blood pressure, and promoting overall cardiovascular health. Choice B, Diabetes mellitus, is managed through monitoring blood sugar levels and a balanced diet rich in whole grains, fruits, and vegetables. Choice C, Parkinson's disease, is a neurological disorder that is not primarily managed through diet modifications. Choice D, Anemia, is a condition characterized by a lack of healthy red blood cells and is typically managed by addressing the underlying cause and sometimes iron supplementation, not by the methods mentioned in the question.

Correct Answer: D

Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.
