Objective: A relationship between dentists and medical doctors should be encouraged to reduce cardiovascular risk in cardiac patients with dental infection. The aim of this study was to evaluate the attitudes of cardiologists and cardiovascular surgeons (cardiac specialists) toward managing endodontic infections and oral health in patients with cardiovascular diseases (CVDs). Methods: A survey of 16 questions assessing knowledge of endodontic infection, dental examination, timing of endodontic treatment, and antibiotic prophylaxis was sent to cardiac specialists in Turkey. The participants' responses were compared by means of the chi-square test (p <= 0.05). Results: Responses were received from 444 (44.71%) participants. Of all participants, 91.4% agreed that endodontic infections are important diseases that should be treated. Cardiac patients were referred to a dentist by 66.6% of the cardiologists and 80.3% of the cardiovascular surgeons (p = 0.002). Almost all participants (97.3%) believed that the heart health of cardiac patients with endodontic infections could be negatively affected by this infection. Conclusion: Although there is not yet any conclusive evidence on whether the presence of an endodontic infection may have an impact on CVDs, this study showed that most cardiac specialists attached importance to endodontic infections.
