Is endocarditis prophylaxis for dental procedures necessary?

Dentists' practice and compliance with current guidelines of infective endocarditis prophylaxis- National survey study

Background

The objective of this study was to assess the attitude, practice, and knowledge of Croatian dentists regarding infective endocarditis (IE) prophylaxis.

Material and Methods

A cross-sectional, self-reporting questionnaire survey was conducted with the participation of 348 Croatian dentists. The questionnaire was designed to collect information on participants’ work experience, place of work, their attitudes related to the treatment of IE-risk patients, knowledge and adherence to IE antibiotic prophylaxis guidelines.

Results

Knowledge and adherence to the current guidelines decreased with the higher years of experience. Compliance with the current guidelines varied, mostly because of respondents’ insecurity regarding which guidelines to follow. AHA guidelines have been most frequently the first choice (25% participants). Surprisingly, 23% of dentists didn’t follow any of the official guidelines. The majority of participants (68%) have declared a lack of preparedness or willingness to treat the patients at risk of IE. Dentists with specialty or working at university/hospital have shown a higher level of knowledge and preparedness to treat IE-risk patients.

Conclusions

The lack of knowledge of guidelines and consequent inconsistencies in IE antibiotic prophylaxis in Croatian dental practice indicates the need for urgent improvement.

Infective endocarditis - An update for dental surgeons

Infective endocarditis (IE) is associated with significant morbidity and mortality. The prevention of infective endocarditis, for many years, has involved the identification of at risk patients undergoing medical or dental procedures and the use of pre-procedural antibiotic prophylaxis. However, evidence regarding the effectiveness of such measures is lacking while evidence is mounting for the adverse effects of inappropriate antibiotic use. International guidelines for antibiotic prophylaxis were amended, radically in some cases to reflect this. Subsequent epidemiological observations of IE have shown mixed results, strengthening calls for well conducted randomised control trials, now that there is genuine clinical equipoise among clinicians about this question.

Dental treatment and recommended management in patients at risk of infective endocarditis

Infective endocarditis (IF) is found in high-risk groups with congenital or acquired cardiac defects. It is caused by episodes of short bacteraemia. The magnitude and duration of bacteraemia caused by dental procedures are decreased by using antibiotic prophylaxis (AP). The aim of this study is to describe and discuss all clinical implications related to IF and dental procedures, and AP before invasive dental procedures. Maintenance of optimal oral health and hygiene is more important than AP in decreasing the risk of IF. Routine daily activities are associated with a similar risk of bacteraemia. It is estimated that antibiotics use in dentistry may represent up to 10% of total antibiotics use, and the risk of developing bacterial resistance should be taken into account.

Improving medical care and prevention in adults with congenital heart disease-reflections on a global problem-part II: infective endocarditis, pulmonary hypertension, pulmonary arterial hypertension and aortopathy

Despite relevant residua and sequels, follow-up care of adults with congenital heart disease (ACHD) is too often not performed by/in specialized and/or certified physicians or centers although major problems in the long-term course may develop. The most relevant encompass heart failure, cardiac arrhythmias, heart valve disorders, pulmonary vascular disease, infective endocarditis (IE), aortopathy and non-cardiac comorbidities. The present publication emphasizes current data on IE, pulmonary and pulmonary arterial hypertension and aortopathy in ACHD and underlines the deep need of an experienced follow-up care by specialized and/or certified physicians or centers, as treatment regimens from acquired heart disease can not be necessarily transmitted to CHD. Moreover, the need of primary and secondary medical prevention becomes increasingly important in order to reduce the burden of disease as well as the socioeconomic burden and costs in this particular patient group.

Controversies in Dentoalveolar and Preprosthetic Surgery

Dentoalveolar surgeries are among the more common procedures performed by oral maxillofacial surgeons. It is only natural that there are several controversies associated with many aspects of this type of surgery. Although good scientific evidence is the basis of most oral maxillofacial procedures, some of what is accepted as common wisdom may not meet strict guidelines of evidence-based practice. This article explores some controversies that are relevant to the current practice of dentoalveolar surgery.
