Visible bleeding during a dental procedure is a reliable predictor of bacteremia. it is not clear which dental procedures are more or less likely to cause transient bacteremia or to result in a greater magnitude of bacteremia than that caused by routine daily activities as chewing food, tooth brushing, or flossing.
a. both statements are true
b. both statements are false
c. the first statement is true and the second statement is false
d. the first statement is false and the second statement is true

The answer is Option D (The first statement is false and the second statement is true)

Explanation:

Bacteremia also known as “blood poisoning,” which can be categorized as transient, intermittent, or persistent is defined as the presence of viable microorganisms in the bloodstream. It usually occurs when the blood becomes infected with bacteria that are alive and capable of reproducing.

Bacteremia can occur in the absence of wound manipulation or other identifiable risk factors. Some factors such as heart rate, blood volume makes it difficult to quantify bacteria that initially gain entrance to the circulation following dental procedures. Visible bleeding during a dental procedure is not a reliable predictor of bacteremia.

Transient bacteremia is common with manipulation of the teeth and periodontal tissues caused by viridans group streptococci and other oral microflora occurs frequently during daily routine activities such as tooth brushing, chewing food.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
