What is Gingivitis?
Correct Answer
C. an inflammation of the gums
Explanation
Gingivitis is an inflammation of the gums. It is a common dental condition characterized by red, swollen, and bleeding gums. It is usually caused by poor oral hygiene, which leads to the buildup of plaque on the teeth. If left untreated, gingivitis can progress to a more severe form of gum disease called periodontitis, which can result in tooth loss. Regular brushing, flossing, and professional dental cleanings can help prevent and treat gingivitis.
2.
What is Periodontitis?
Correct Answer
C. Inflammation of the supporting structures of the tooth or teeth including the gum, the periodontal ligament and the jawbone
Explanation
Periodontitis is the inflammation of the supporting structures of the tooth or teeth, which includes the gum, the periodontal ligament, and the jawbone. This condition can affect individuals of any age and is not specific to either children or the elderly. It is a common dental problem that can lead to tooth loss if left untreated.
3.
Smoking or using tobacco products accelerates the chance for tooth loss.
Correct Answer
A. True
Explanation
Smoking or using tobacco products can increase the risk of tooth loss. This is because tobacco use can lead to gum disease, which is a major cause of tooth loss. Smoking can also reduce blood flow to the gums, making it harder for them to heal and fight off infection. Additionally, tobacco use can stain teeth and contribute to bad breath, further impacting oral health. Therefore, it is true that smoking or using tobacco products accelerates the chance for tooth loss.
4.
Oral habits such as cheek and lip biting increase the chance for oral cancer.
Correct Answer
A. True
Explanation
Oral habits such as cheek and lip biting can increase the risk of oral cancer because they can cause chronic irritation and damage to the tissues in the mouth. Constant biting can lead to the formation of ulcers or sores that do not heal properly, which can potentially develop into cancerous cells over time. Additionally, the repetitive trauma from biting can weaken the immune system in the affected area, making it more susceptible to the development of cancer. Therefore, it is important to avoid these oral habits to reduce the risk of oral cancer.
5.
The best age to start take a child to the dentist is by what age?
Correct Answer
B. Between 18-24 months
Explanation
The best age to start taking a child to the dentist is between 18-24 months. This is because by this age, most children have their first set of teeth and it is important to establish good oral hygiene habits early on. Additionally, starting dental visits at a young age allows the dentist to monitor the child's dental development, identify any potential issues, and provide preventive care and education to parents on proper oral care for their child.
6.
Bad breath is usually caused by:
Correct Answer
C. Bacteria that are found on the tongue
Explanation
Bad breath is usually caused by bacteria that are found on the tongue. These bacteria can produce unpleasant odors, resulting in bad breath. While foods like onions or garlic can also cause temporary bad breath, the presence of bacteria on the tongue is a more common and persistent cause. Additionally, not flossing regularly can contribute to bad breath by allowing food particles to remain between the teeth, providing a breeding ground for bacteria. However, the primary cause of bad breath is the bacteria found on the tongue.
7.
When should one change their toothbrush?
Correct Answer
B. Once every 2 to 3 months or after a flu or cold
Explanation
It is recommended to change toothbrushes once every 2 to 3 months or after a flu or cold. This is because toothbrush bristles can become frayed and less effective in cleaning the teeth over time. Additionally, after a flu or cold, the toothbrush can harbor bacteria and viruses, which can lead to reinfection. Therefore, it is important to replace the toothbrush regularly to maintain proper oral hygiene and prevent the spread of germs.
8.
Fluoride is useful because it:
.
Correct Answer
A. Decreases the chance for cavities
Explanation
Fluoride is useful because it decreases the chance for cavities. Fluoride helps to strengthen the enamel of teeth, making them more resistant to decay caused by acids produced by bacteria in the mouth. By regularly using fluoride toothpaste or receiving fluoride treatments, individuals can reduce their risk of developing cavities and maintain good oral health.
9.
As one gets older, the chance for cavities decreases.
Correct Answer
B. False
Explanation
The statement is false because as one gets older, the chance for cavities actually increases. This is because as we age, our teeth become more prone to decay and damage. Factors such as receding gums, dry mouth, and a lifetime of wear and tear on the teeth contribute to a higher risk of cavities in older individuals. Regular dental care and good oral hygiene practices are essential to prevent cavities at any age.
10.
If one brushes three time a day instead of twice, flossing is not necessary.
Correct Answer
B. False
Explanation
Brushing three times a day does not eliminate the need for flossing. While brushing is essential for removing plaque and food particles from the surfaces of teeth, it cannot reach the spaces between teeth where plaque can accumulate. Flossing is necessary to clean these areas and prevent gum disease and tooth decay. Therefore, even if someone brushes their teeth three times a day, flossing remains an important part of maintaining good oral hygiene.
