Caries progression does NOT cause which of the following?
Show answer and explanation
Correct answer: D. Increase in serum immunoglobulin — this is NOT a direct caries effect
✓ D) Increase in serum immunoglobulin is NOT caused by caries.
Pulp responses to caries progression: (1) SCLEROTIC DENTIN: odontoblasts deposit mineral in tubules ahead of the caries front → reduced permeability = defensive response; (2) DEAD TRACTS: dentin tubules where odontoblastic processes have died → appear dark on transmitted light, empty tubules; (3) REACTIONARY (IRRITATION) DENTIN: new dentin deposited by surviving odontoblasts; (4) INFLAMMATORY PULP RESPONSE (pulpitis). Immunoglobulins increase systemically in response to systemic infection — caries is a LOCAL process. Caries does not significantly alter serum immunoglobulin levels.
