Amoxicillin–clavulanic acid remains one of the most frequently prescribed antibiotics in pediatric dentistry, particularly for odontogenic infections with suspected beta-lactamase–producing bacteria.

✅ Pharmacological Differences Between Pediatric and Adult Patients

Pharmacokinetics
Children differ from adults in drug absorption, distribution, metabolism, and elimination. Factors such as higher total body water, lower plasma protein binding, and immature hepatic and renal function directly influence antibiotic dosing and frequency.

Pharmacodynamics
Pediatric patients may demonstrate altered therapeutic and toxic responses to antibiotics. Consequently, weight-based dosing and strict adherence to maximum recommended doses are mandatory to avoid toxicity or subtherapeutic exposure.

📊 Comparative Table: Pharmacokinetic and Pharmacodynamic Differences in Antibiotic Prophylaxis

Pharmacological Parameter	Pediatric Patients	Adult Patients
Drug Absorption	Variable gastrointestinal absorption due to immature digestive function	Predictable and stable absorption patterns
Drug Distribution	Higher total body water and lower plasma protein binding	More consistent volume of distribution
Metabolism	Immature hepatic enzyme systems	Fully developed hepatic metabolism
Renal Elimination	Reduced glomerular filtration rate in younger children	Stable renal clearance in healthy adults
Dose Calculation	Strict weight-based dosing required	Standard fixed dosing

💬 Discussion
The overuse of antibiotic prophylaxis in dentistry has been identified as a contributing factor to antimicrobial resistance, adverse drug reactions, and unnecessary healthcare costs. Pediatric patients are particularly vulnerable due to developing physiological systems and a higher risk of dosing errors.
In adults, systemic comorbidities often influence prophylactic decisions, whereas in children, cardiac status and immune maturity play a central role. Evidence-based guidelines consistently emphasize risk stratification over routine prescription, regardless of age group.

▪️ Prioritize definitive dental treatment (pulp therapy, extraction, incision and drainage) whenever possible.
▪️ Prescribe antibiotics only when systemic involvement or facial cellulitis is present.
▪️ Choose amoxicillin as the first-line agent; use clindamycin for penicillin-allergic patients.
▪️ Avoid antibiotics for pulpitis, localized abscess, or routine procedures.
▪️ Follow weight-based pediatric dosing strictly:
° Amoxicillin: 20–40 mg/kg/day divided every 8 hours
° Amoxicillin–clavulanate: 25–45 mg/kg/day divided every 12 hours
° Clindamycin: 10–25 mg/kg/day divided every 8 hours
▪️ Educate parents on correct administration and the importance of completing the course.
▪️ Reassess cases within 24–48 hours when antibiotics are prescribed.

✍️ Conclusion
Antibiotics are not routinely needed in pediatric dentistry, and local treatment is sufficient in most cases. Their use should be reserved for systemic infection, facial cellulitis, medically complex patients, or situations where dental treatment cannot be immediately performed. Adopting evidence-based prescribing practices reduces antimicrobial resistance and ensures high-quality pediatric dental care.

° Macrolides (azithromycin, clarithromycin): concentration-time dependent (AUC/MIC); azithromycin has a long half-life, clarithromycin is metabolized via CYP3A4.
° Doxycycline: broad distribution, concentration-dependent; short-course use does not cause permanent tooth staining.

✅ Practical considerations and stewardship

° Avoid clindamycin due to C. difficile risk.
° Avoid cephalosporins if prior anaphylaxis to penicillin.
° Do not prescribe AP for routine dental care or orthodontics.
° Delay elective procedures if the patient is already on antibiotics.
° Promote antibiotic stewardship: limit use, educate parents, and prioritize oral hygiene.

Choosing between amoxicillin and clindamycin in pediatric dentistry requires a clear understanding of their mechanisms of action, clinical indications, weight-based dosing formulas, and safety profiles.

💬 Discussion
Evidence shows that AP prevents very few cases of IE, while maintaining good oral hygiene and controlling plaque reduce bacteremia more effectively. Current guidelines restrict AP to high-risk children undergoing invasive dental procedures. This approach reduces unnecessary antibiotic exposure and the risk of adverse effects.

✍️ Conclusion
Antibiotic prophylaxis in pediatric dentistry is not routine. It is indicated only for children with high cardiac risk undergoing invasive dental procedures. Amoxicillin 50 mg/kg (max 2 g) remains the first-line drug. Alternatives include oral cephalosporins, macrolides, or doxycycline (selected cases), with clindamycin excluded. Integration of antibiotic stewardship principles and collaboration with pediatricians and cardiologists is essential.

Antibiotic Prophylaxis in Pediatric Dentistry: When and How to Use It Safely in 2025

Antibiotic prophylaxis in pediatric dentistry is a preventive measure used to avoid serious systemic infections, such as infective endocarditis, in children undergoing dental procedures.

In comparison, the metabolism of a drug in a child is different from that of an adult, so the administration of an antibiotic should be taking into account the diagnosis, age and weight of the pediatric patient

The practice is guided by evidence-based protocols from organizations such as the American Heart Association (AHA) and the American Academy of Pediatric Dentistry (AAPD). Its use must be justified, as improper administration increases the risk of adverse effects and antibiotic resistance.

✅ What Is Antibiotic Prophylaxis in Pediatric Dentistry?
This involves the preventive administration of antibiotics before invasive dental procedures in children who are at high risk for systemic infections. The aim is to minimize transient bacteremia that could colonize vulnerable tissues, such as the heart valves, particularly in immunocompromised or medically complex pediatric patients.

✅ Mechanism of Action
Antibiotics used for prophylaxis work by eliminating or reducing oral bacteria that can enter the bloodstream during dental procedures. The antibiotic is given 30–60 minutes before treatment to achieve optimal blood levels.

° Amoxicillin inhibits bacterial cell wall synthesis (bactericidal).
° Clindamycin inhibits bacterial protein synthesis (bacteriostatic or bactericidal depending on concentration).
° Macrolides (azithromycin, clarithromycin) also inhibit protein synthesis and are used in penicillin-allergic patients.

✅ Clinical Indications

1. High-Risk Cardiac Conditions (Per AHA Guidelines)
Antibiotic prophylaxis is recommended for children with:
° Prosthetic heart valves or materials
° History of infective endocarditis
° Certain congenital heart defects (unrepaired, recently repaired with residual defects, or cyanotic CHD)
° Cardiac transplant recipients with valve disease

2. Immunocompromised Patients
Including those with:
° Cancer undergoing chemotherapy
° Neutropenia
° Organ transplants
° Long-term corticosteroid therapy
° IV bisphosphonate therapy

3. High-Risk Dental Procedures
Prophylaxis is recommended only for invasive procedures such as:
° Tooth extractions
° Periodontal surgery
° Deep scaling and root planing
° Any procedure causing mucosal or gingival bleeding

✅ Recommended Antibiotics and Pediatric Dosing

💬 Discussion
Current research and AHA/AAPD guidelines stress that antibiotic prophylaxis should only be used when clinically indicated. Studies have shown that eliminating routine prophylaxis in low-risk patients did not increase the incidence of infective endocarditis. Misuse or overuse contributes to antibiotic resistance, Clostridioides difficile infection, and other complications.
Dentists must evaluate each child’s medical history and assess whether the risk justifies prophylactic use. Furthermore, educating caregivers on the responsible use of antibiotics is essential to support safe dental practices.

💡 Conclusion
Antibiotic prophylaxis in pediatric dentistry is a valuable tool for preventing severe infections but should be limited to patients with specific high-risk conditions. Updated guidelines from the AHA and AAPD emphasize evidence-based decision-making and individual risk assessment. Dental professionals must stay informed and adhere to standardized protocols to ensure the best outcomes for pediatric patients.

Update on antibiotic prophylaxis in pediatric patients

Antibiotic prophylaxis aims to prevent the presence of a new infection from a therapeutic procedure. This preventive action is more important if the patient is immunocompromised.

In pediatric dentistry or general dentistry, the general health status of the child must be known, as well as his or her history and the severity of the infection, in order to determine the correct administration of antibiotics.
