A patient presents with discoloration limited to #7 and #8. What is the most likely cause?
Show answer and explanation
Correct answer: C. Trauma
- A. Fluorosis is symmetric and generalized, affecting homologous teeth bilaterally.
- B. Amelogenesis imperfecta is a generalized, inherited defect affecting the entire dentition.
- C. Correct. Localization to two adjacent anterior teeth is the signature of trauma — pulpal hemorrhage and subsequent necrosis or pulp canal obliteration discolor only the injured teeth.
- D. Tetracycline staining is generalized and banded, affecting all teeth developing during exposure.
