Oral Health Flashcards

What is the primary goal of oral health care in dental hygiene?

Answer: To prevent oral diseases

The primary goal of oral health care in dental hygiene is proactive prevention of common oral diseases. This includes preventing dental caries (cavities), periodontal disease (gum disease), and other infections through education, regular cleanings, and targeted preventive treatments. By focusing on prevention, dental hygienists help maintain overall oral health and well-being.

Which of the following is most effective in preventing dental caries?

Answer: Regular fluoride treatments

Regular fluoride treatments are highly effective in preventing dental caries because fluoride strengthens tooth enamel. This makes the enamel more resistant to acid attacks produced by bacteria and sugars, which are the primary cause of cavities. While other practices contribute to oral health, fluoride directly enhances the tooth's ability to resist decay.

What is the role of saliva in maintaining oral health?

Answer: Neutralizing acids and protecting teeth

Saliva plays a crucial role in maintaining oral health by neutralizing acids produced by bacteria after food consumption, which helps prevent demineralization of tooth enamel. It also aids in remineralization by providing minerals like calcium and phosphate, and its flow helps cleanse the mouth of food debris and bacteria, protecting against decay.

Which dental condition is characterized by inflammation of the gingiva without bone loss?

Answer: Gingivitis

Gingivitis is specifically defined as inflammation of the gingiva (gums) that does not involve loss of the supporting bone structure around the teeth. It is a reversible condition, typically caused by plaque accumulation, and is characterized by redness, swelling, and bleeding gums without clinical attachment loss.

Which nutrient is most important for maintaining healthy gums?

Answer: Vitamin C

Vitamin C is essential for the synthesis of collagen, a vital protein that forms the connective tissue in the gums and other parts of the body. A deficiency in Vitamin C can lead to weakened connective tissues, poor wound healing, and bleeding gums, directly impacting gum health and integrity.
