Background and Aim: Local anesthesia plays an important role in dentistry. Although hypersensitivity reactions to local anesthetic drugs are rare,but they are more common in dental cartridge components. This study reports a rare case of hypersensitivity to components of local anesthesia cartridge.
Case Report: A 61-year-old female patient referred to The Medical Council to complain the dentist about pigmentation appeared around the eyes and lips. The patient had no history of systemic disease or food and medication allergy, and a year before complaint, had referred to dentist for anterior and premolar teeth extraction. About an hour later, black macules and patches with ill-defined borders appeared in peri-orbit and peri-oral areas. By further examination, hypersensitivity reaction to the local anesthetic cartridge was reported as the most likely diagnosis.
Conclusion: This case states the importance of differentiating the lesion from other causes of pigmentation. It is also recommended to pay attention to the type of local anesthesia cartridge used and its component. |
