Select causes of internal resorption:
1) biologic pulp treatment by direct pulp capping using calcium hydroxide;
2) chronic pulpitis with small necrotic foci within the pulp due to the caries process;
3) periodontal procedures;
4) whitening of discoloured teeth with a viable pulp using 10-16% carbamide peroxide;
5) iatrogenic stimuli caused by high temperatures generated during cavity preparation.
The correct answer is:
2) chronic pulpitis with small necrotic foci within the pulp due to the caries process;
3) periodontal procedures;
