The prevention and treatment of oral disease is based on managing the risk, and involves identifying risk factors
Correct Answer
A. Both statements are true
Explanation
The explanation for the given correct answer is that the prevention and treatment of oral disease indeed rely on managing the risk. This means that efforts are made to identify and address the risk factors that contribute to oral diseases, such as poor oral hygiene, tobacco use, unhealthy diet, and lack of regular dental check-ups. By managing these risk factors, individuals can reduce their chances of developing oral diseases and maintain good oral health. Therefore, both statements in the question are true.
2.
Risk factors do not necessarily imply cause and effect?
Correct Answer
A. True
Explanation
Risk factors are factors that increase the likelihood of a certain outcome or event occurring. However, the presence of a risk factor does not guarantee that the outcome will occur. Therefore, risk factors do not necessarily imply cause and effect. It is possible for a risk factor to be present without the outcome occurring, or for the outcome to occur without the presence of the risk factor.
3.
Tick the SYSTEMIC factors that affect the development of oral disease:

Fluoride in water is colourless, odourless and tasteless. Fluoride is only needed for young children.
Correct Answer
C. The first statement is true, the second statement is false
Explanation
The first statement is true because fluoride in water is indeed colorless, odorless, and tasteless. The second statement is false because fluoride is not only needed for young children but also for people of all ages.
11.
All of the following are true statements of fluoride, except?
Correct Answer
A. Large amounts of fluoride are needed to strengthen teeth and bones
Explanation
Fluoride-enriched areas on enamel being less acid soluble, fluoride assisting calcium and phosphate ions to latch onto the enamel surface, and fluorine being the 9th element in the periodic table are all true statements about fluoride. However, large amounts of fluoride are not needed to strengthen teeth and bones.
