Insights
Children at high risk for infective endocarditis (IE) showed similar dental health to healthy peers, despite high caries rates. Parental awareness of oral health
Area of Science:
- Pediatric Cardiology
- Oral Health
- Infective Endocarditis
Background:
- Children with prior infective endocarditis (IE) or prosthetic heart valves face very high IE risk.
- Oral health is a critical factor in managing IE risk in high-risk pediatric populations.
Purpose of the Study:
- To compare dental health between high-risk children and healthy controls.
- To assess parental awareness of oral health's importance in preventing IE.
Main Methods:
- Dental examinations were conducted on 28 high-risk children and 28 healthy controls.
- Parental awareness of oral health was evaluated using questionnaires.
Main Results:
- No significant differences in DMFT scores were found between the high-risk and control groups.
- 36% of the high-risk group had untreated caries, despite excellent parental knowledge.
- Parental awareness regarding the link between oral health and IE was notably high.
Conclusions:
- Oral health status did not significantly differ between high-risk cardiac children and healthy controls.
- High rates of untreated caries in the study group are concerning, even with good dental awareness and attendance.
- Further investigation into maintaining oral hygiene in high-risk pediatric populations is warranted.
Background:
Children with previous experience of infective endocarditis or with prosthetic heart valve are considered at very high risk for infective endocarditis.
Aim:
The aim of this study was to compare the dental health of a group of these children with a group of healthy controls and to determine parental awareness of the importance of good oral health.
Design:
Oral examination was carried out in 28 children with previous infective endocarditis or a prosthetic heart valve to assess oral health. Findings were compared to a healthy control group of 28. Questionnaires were distributed to the parents to assess awareness of oral health.
Results:
There was no significant difference in DMFT scores of study and control group (2.43 +/- 3.72 and 1.36 +/- 2.5 respectively) or in DMFT scores of study and control group (1.5 +/- 1.73 and 1.15 +/- 1.42 respectively), 36% of the study group had untreated caries. Parental knowledge of the link between oral health and infective endocarditis was excellent.
Conclusions:
There were no significant differences between the oral health of cardiac children and healthy children although the dmft and DMFT scores of the study group were high. Of concern was the proportion of children with untreated caries in spite of good dental awareness and attendance.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
