Cardiac ischemia, such as angina pectoris or myocardial infarction, is associated with pain in the oral cavity, lower jaw, head, or neck, or spanning from the left upper arm to the shoulder. When presenting to a dentist, however, appropriate treatment for such patients is often delayed, as dental problems are usually the first to be suspected when the chief complaint is orofacial pain. This report describes a case of a 70-year-old woman who was aware of pain and a burning sensation in the oral cavity upon exertion for a year prior to presenting at our clinic. She had been examined by her family physician, an otolaryngologist, and another dentist, none of whom found any abnormalities other than suspected periodontal disease and caries, for which she was treated. An examination at our clinic revealed no abnormal dental findings that would have been consistent with the mandibular pain, however. Although no chest symptoms were reported, pain was elicited on exertion, suggesting cardiogenic toothache. An immediate referral to a cardiologist was therefore made on the same day. The patient visited the cardiology department of the University Hospital of Tokyo Dental College 6 days later. The increased frequency of symptoms on exertion suggested unstable angina, and the patient was admitted to the emergency department on the same day. Emergency coronary angiography showed that right coronary artery #1 was 99% stenosed proximally (highly calcified plaque). The diagnosis was unstable angina pectoris, with the right coronary artery #1 as the responsible lesion, and percutaneous coronary angioplasty was performed on the same day. Subsequently, all the orofacial pain disappeared, confirming unstable angina as the cause. The pain characteristics in this case were consistent with pain associated with cardiac ischemia, which led to the immediate referral to the cardiology department. In cases of toothache associated with cardia ischemia, it is essential to seek cardiological care as soon as possible. |
