Choose such requirements for materials used for biologic pulp treatment, which are fully satisfied by products based on calcium hydroxide:
1) tissue biocompatibility;
2) antibacterial and anti-inflammatory action;
3) odontotropic action;
4) good dentin and filling material adherence;
5) resistance to chemical agents;
6) resistance to mechanical forces;
7) good RTG visibility.
Correct answer is:
2) antibacterial and anti-inflammatory action;
3) odontotropic action;
4) good dentin and filling material adherence;
5) resistance to chemical agents;
6) resistance to mechanical forces;
7) good RTG visibility.
Correct answer is:
- A. 1,2,3,6.
- B. 2,3,4.
- C. 1,2,3,7.
- D. 1,2,3,5.
- E. 1,2,5,7.
Hint
Calcium hydroxide is biologically excellent but physically weak: consider pH, dentin bridging, solubility, strength and radiopacity.
