title: Two unusual cases of dental (periapical) infection.
abstract: Cutaneous sinus tracts of dental origin are often a diagnostic challenge. A delay in correct diagnosis can result in inappropriate treatments. We describe two unusual cases of periapical infection. The first patient presented with a fistulized tumoral mass under the chin present for 1 year. The patient had only one tooth, and that was anatomically unrelated to the tumor. Radiological examination showed a dormant tooth that was infected periapically. The second case was a man who complained of asymmetry and change in his left nasolabial fold of 4-5 week's duration. On examination, the nasolabial folds were asymmetric without any sign of facial palsy. On intraoral examination, there was a severely decayed tooth on the same side. Radiological survey confirmed periapical infection. A few weeks after proper treatment, the nasolabial folds became symmetric.
