The document appears to be a study guide or test for a student on dental caries. It includes multiple choice and true/false questions testing knowledge of topics like the stages of caries, diagnosis of caries, treatment of caries, and pulpitis. Some sample questions ask about residual caries, inactive lesions, hyposalivation and its effects, early childhood caries, factors that slow caries progression, and characteristics of active versus arrested caries lesions.

1. The student instrument<br />DCP (dental caries) <br />For all Dr. Kauser’s lectures and the 2 lectures of Dr. Nizam.<br />Write the correct answer.<br />Dental plaque that develops over a long period of time becomes ………….

2. Fermentable carbohydrates are …………… that are easily metabolized by the bacteria present in our mouth to form acid compounds.

3. ……….. a type of complex carbohydrates are harmless because they are not digested in the mouth.

4. The plaque remains acid for some time, taking ……….. minutes to return to its normal pH.

5. ………… is most cariogenic sugar.

6. Circle the correct answer.<br /> 1-Residual caries are:<br /> a.caries that are very deep to the dentin<br /> b. demeneralized tissue that are left in place before a filling is placed<br /> c. carious enamel that does not affect the dentin<br />2- Inactive lesions are:<br /> a. progressive<br /> b. arrested<br /> c. is not considered a carious lesion<br />3- Moderate challenge :<br /> a. Involves anterior teeth which are usually caries -free<br /> b. are on the occlusal part of the teeth<br /> c. are on the proximal surface of the posterior teeth.<br />4- Hyposalivation causes:<br /> a. rampant caries<br /> b. arrested caries<br /> c. multiple caries<br />5-ECC stands for and they are another name of nursing caries :<br /> a. early childhood caries<br /> b. early corrosive caries<br /> c. early cast caries<br />This picture shows :
