Terumi Ayuse,1 Shinji Kurata,2 Takao Ayuse1,2 1Nagasaki University Hospital, Department of Special Care Dentistry, Nagasaki, Japan; 2Nagasaki University Hospital, Department of Dental Anesthesiology, Nagasaki, JapanCorrespondence: Takao AyuseNagasaki University Graduate School of Biomedical Science, Department of Translational Medical Sciences, Division of Clinical Physiology, Nagasaki, JapanTel +81-95-849-7714Fax +81-95-849-7715Email [email protected]: We report a case in which effective dental anesthetic management was achieved using procaine hydrochloride for a patient who had an unknown history of allergic reactions to lidocaine.Case Presentation: Because the patient refused to undergo screening tests using any of the amide-type local anesthetics because of her extreme fear against local anesthetics that she had been administered previously, procaine hydrochloride, which is an ester-form local anesthetic, was the only agent to be tested on this patient at the department of dermatology. Consequent to a negative allergy test, we performed complete dental treatment using procaine hydrochloride after additional chairside drug challenge tests using minimum test dose under vital sign monitoring.Conclusion: The success of dental treatment using procaine hydrochloride may have relieved the patient’s fear of local anesthesia. We discuss an important aspect of treatment planning for patients with a history of complications during local anesthesia.Keywords: allergic reaction, amide-type local anesthesia, procaine hydrochloride, dental fear, dental anxiety, local anesthesia, complication
