Summary
Most dentists in Western Australia follow infective endocarditis (IE) prophylaxis guidelines for valvular heart disease (VHD). However, awareness of rheumatic heart disease (RHD) control programs remains low.
Area of Science:
- Dental Public Health
- Infectious Diseases
- Cardiology
Background:
- Limited data exists on dentists' understanding of infective endocarditis (IE) prophylaxis guidelines.
- Valvular heart disease (VHD) management in dental settings requires further investigation.
Purpose of the Study:
- To assess dentists' knowledge and application of IE prophylaxis guidelines for VHD in Western Australia.
- To evaluate awareness of rheumatic and non-rheumatic VHD management protocols.
Main Methods:
- A cross-sectional online survey was distributed to dentists in Perth, Western Australia.
- The survey utilized a Qualtrics questionnaire based on stakeholder consultations.
- Dentists were sampled across socio-economic quintiles.
Main Results:
- 90.2% of surveyed dentists adhered to the Australian Therapeutic Guidelines (ATG) for IE antibiotic prophylaxis in VHD.
- Nearly all dentists prescribed prophylaxis for invasive procedures like extractions (100%) and periodontal surgery (95.1%).
- A significant majority (92.7%) were unaware of the national rheumatic heart disease (RHD) control program.
Conclusions:
- Dentists generally follow established guidelines for IE prophylaxis in VHD.
- There is a notable gap in dentists' knowledge regarding national RHD guidelines and local control programs.

The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
