Final answer:
Type I and Type II diabetics are indeed more prone to caries, but attributing this solely to increased saliva glucose is an oversimplification. There are multiple factors that contribute to the risk of caries in diabetic individuals.
Step-by-step explanation:
Type I and Type II diabetics are at higher risk for caries; this is a true statement. The risk is often associated with higher blood glucose levels, which can result in increased levels of glucose in saliva and a higher acidic environment in the mouth. However, attributing this risk primarily to the amount of glucose in their saliva is not entirely accurate as there are multiple factors involved in the development of caries such as oral hygiene practices, frequency of sugar consumption and saliva flow rate.
Conditions with high blood glucose levels, including diabetes, may lead to increased glucose in saliva and potential secondary complications such as gum disease which can also contribute to an increased risk for caries. Both Type 1 diabetes, which is an autoimmune disease resulting in insulin deficiency, and Type 2 diabetes commonly associated with insulin resistance can result in high blood sugar levels if not properly managed. These elevated blood sugar levels in the body can have various health implications, including dental health issues like caries. Therefore while the first statement is correct, the second statement is an oversimplification of the mechanism leading to increased caries risk. The answer to the given question is C. The first statement is true; the second statement is false.
