Question 549 · LDEK · Resorption
Potential causes of internal resorption are:
1) biological treatment of the pulp with direct pulp capping using calcium hydroxide;
2) chronic pulp inflammations and small necrotic foci in the pulp resulting from caries;
3) subgingival scaling;
4) whitening of discolored teeth with vital pulp using 10-16% carbamide peroxide;
5) traumatic factors, such as poorly adjusted fillings, prosthetic restorations, excessive heat generated during cavity preparation and teeth grinding.
The correct answer is:
2) chronic pulp inflammations and small necrotic foci in the pulp resulting from caries;
3) subgingival scaling;
4) whitening of discolored teeth with vital pulp using 10-16% carbamide peroxide;
5) traumatic factors, such as poorly adjusted fillings, prosthetic restorations, excessive heat generated during cavity preparation and teeth grinding.
