Background: Poor oral health is known to be a risk factor for infective endocarditis (IE) and acquired cardiovascular disease. Many patients with congenital heart disease (CHD) are at risk for developing IF,. Excellent oral health is deemed essential to prevent IE, a potentially life-threatening condition, and therefore is important in adults with congenital heart defects (ACHD). As data on oral heath in ACHD are scarce, the current study aims to assess the prevalence of caries among ACHD and the knowledge of patients about oral health as a risk factor for IE and cardiovascular disease. Methods: A cross-sectional study included ACHD who subsequently presented at the German Heart Center Munich. The participants completed a questionnaire assessing oral health and risk awareness. Additionally, as an indicator of caries prevalence, a dentist documented the DMFT index (sum of decayed, missing and filled teeth). Results: The median age of the 112 participants was 31.5 (range, 18-77) years. Forty-three patients (38%) were unaware of a correlation between oral health and heart disease. Twelve participants (11%) did not know about poor oral health being a risk factor for cardiovascular diseases. Less than half of the surveyed patients knew the term endocarditis. An additional twelve patients (11%) reported caveats against dental treatment because of their CHD. In twenty-three patients (21%), caries was found at the dentine level. The mean DMFT index, representing caries prevalence, was 7.91 (16.54). There was no correlation between the Bethesda criteria of CHD and the DMFT index (P=0.69). The DMFT index was higher in patients at high risk for IE (P<0.01). However, this difference in the caries score was mainly clue to more extracted and filled teeth in the high-risk patients for IE, whereas the number of decayed teeth did not differ significantly (P=0.09). Conclusions: The awareness of the importance of optimized oral health in ACHD needs to be improved.
