Practice Questions Flashcards

What should you do if your mast becomes wet?

Answer: Change it immediately

In a dental context, if protective equipment like a mask or gown (potentially referred to as 'mast' due to a typo) becomes wet, especially with bodily fluids, its barrier properties are compromised. Therefore, it should be changed immediately to maintain proper infection control. This action is crucial for protecting both the patient and the dental professional from potential contamination.

How often should one clean their teeth each day?

Answer: Twice

Dental professionals generally recommend cleaning teeth twice a day, typically in the morning and before bed. This frequency helps to effectively remove plaque and food debris, preventing the buildup of bacteria. Regular brushing twice daily is essential for maintaining good oral hygiene and preventing issues like cavities and gingivitis.

What proportion of water is a plague?

Answer: 80%

Dental plaque is a sticky, colorless film of bacteria that constantly forms on teeth. It is primarily composed of bacteria, their byproducts, and an extracellular matrix, with a significant water content. Approximately 80% of plaque's composition is water, which contributes to its gelatinous consistency and ability to adhere to tooth surfaces.

What is the initial indication of gingivitis?

Answer: Bleeding

The initial and most common sign of gingivitis, which is inflammation of the gums, is bleeding. Healthy gums do not bleed when brushed or flossed. Bleeding gums indicate an inflammatory response to plaque buildup along the gumline, signaling the need for improved oral hygiene.

What does the acronym CITA mean?

Answer: Council of interstate testing agencies

CITA stands for the Council of Interstate Testing Agencies. This organization is involved in developing and administering standardized examinations, particularly in fields like dental hygiene. Its purpose is to ensure competency and facilitate licensure across different states, promoting consistent professional standards.

What does it mean for the environment to be in balance?

Answer: Homeostasis

Homeostasis refers to the ability of an organism or system to maintain a stable internal environment despite external changes. In biology, it describes the dynamic equilibrium of physiological processes that keep conditions like temperature, pH, and fluid balance within optimal ranges. This balance is crucial for proper functioning and survival.

What is the supragingival source of nutrition?

Answer: Calcium

Supragingival calculus (tartar) forms above the gumline and is primarily mineralized plaque. Its mineralization is largely influenced by calcium and phosphate ions present in saliva. Therefore, calcium from saliva is considered a primary source of nutrition (minerals) for the formation of supragingival calculus, contributing to its hardened structure.
