We present a case of tooth extraction for a 25-year-old patient with a history of secondary methemoglobinemia at 6 months of age caused by Acetaminophen.
The tooth extraction was performed under local anesthesia using 2% lidocaine with 1：80,000 epinephrine in an operating room equipped with respiratory support.
As a result, the treatment was successfully completed and we found no significant signs of secondary methemoglobinemia such as cyanosis, dyspnea and rise in blood methemoglobin concentration.
