Question

The biologic nature of the oral environment and the size of the oral cavity restrict the use of dental materials. One restriction is the degradation of restorations.

a. the first statement is true, the second statement is false

b. the first statement is false, the second statement is true

c. both statements are true

d. both statements are false

Answer 1

The biological nature of the oral environment and the size of the oral cavity restrict the use of dental materials due to factors such as moisture and bacteria that can lead to degradation of restorations, making both the first and second statements true.

Step-by-step explanation:

The question relates to the use of dental materials in the oral environment and the subject would fall under Health or Medicine at the college level. Answering the original question, the biologic nature of the oral environment and the size of the oral cavity indeed restrict the use of dental materials. One of the main reasons for this is the degradation of restorations due to the challenging conditions in the mouth, such as moisture, varying pH levels, and the presence of bacteria. The first statement is true because the oral environment does impose limitations on the types of materials that can be used successfully in dental restorations. The second statement is also true because one of the primary concerns with dental materials is their ability to withstand the oral environment without degrading over time. Therefore, the correct answer to the question is c. both statements are true.
