Answer to Question 1

ANS: C
Plaque is the primary cause of most tooth, gum (gingiva), and periodontal disease. Plaque, the whitish yellow substance that builds up on teeth and gum lines, is thought to originate from saliva. Plaque forms a sticky meshwork that traps bacteria and food particles. If not removed regularly, it thickens, and bacteria proliferate. Sugar is not a cause of dental disease as such but becomes a problem when poor oral hygiene allows it to collect in the oral cavity. Halitosis is a symptom of poor oral hygiene but is not a cause of dental disease. Although smoking can contribute to periodontal disease through vasoconstriction, it is not a cause of dental disease.

Answer to Question 2

ANS: B
Candidiasis is a fungal infection caused by Candida albicans, the most common organism associated with oral infections. It is often called the disease of the diseased because it appears in debilitated patients and patients taking a variety of medicines. Aspergillosis is caused by the fungus Aspergillus, which is commonly found growing on dead leaves, stored grain, or compost piles, or in other decaying vegetation. Although it is similar to candidiasis in its occurrence in debilitated patients, it is not as common. Trichomoniasis is a common parasitic sexually transmitted disease. Brucellosis is a zoonotic infection transmitted from animals to humans by the ingestion of infected food products, direct contact with an infected animal, or inhalation of aerosols.
