Generally, patients who wear dentures have reduced masticatory efficiency. Mandibular implant-supported dentures can have positive effects on the clinical aspects of mastication and swallowing.

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: 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.

Correct Answer: A

Rationale: The correct answer is A) Both statements are true. Explanation: 1. Poor nutrition can lead to delayed eruption and exfoliation of deciduous teeth: Nutritional deficiencies, especially of essential nutrients like calcium and vitamin D, can affect the development of teeth, leading to delays in the eruption and shedding of deciduous teeth. 2. Poor nutrition can increase dental caries susceptibility: Malnutrition can alter the composition of saliva, reducing its protective properties against dental caries. Saliva plays a crucial role in maintaining oral health, and changes in its composition due to malnutrition can increase the risk of dental caries. Educational context: Understanding the impact of nutrition on oral health is essential for healthcare professionals, especially those working with children. By recognizing the connection between poor nutrition and oral health issues like delayed tooth development and increased caries susceptibility, healthcare providers can emphasize the importance of a balanced diet for overall oral health. This knowledge can inform preventive strategies and interventions to promote better oral health outcomes in at-risk populations. Incorrect options: B) Both statements are false: This is incorrect as both statements are supported by evidence linking poor nutrition to oral health issues. C) The first statement is true; the second is false: This is incorrect as both statements are true and are interrelated in explaining the impact of poor nutrition on dental health. D) The first statement is false; the second is true: This is incorrect as both statements are true based on the relationship between nutrition, saliva composition, and oral health outcomes.

Correct Answer: B

Rationale: The correct answer is B. Hard fats take longer to digest than soft fats because hard fats are solid at body temperature, making them more challenging to break down. Choice A is true as the majority of ingested fats are absorbed. Choice C is correct as fats indeed contribute to the palatability and flavor of foods. Choice D is accurate as cooked fats can enhance the texture of foods.
