✅ Indications for Antibiotic Use in Pediatric Dentistry
According to the American Academy of Pediatric Dentistry (AAPD) and other professional bodies, antibiotics should be prescribed in pediatric patients only when there is clear evidence of systemic involvement or the risk of spread of odontogenic infections. The primary indications include:

° Acute facial swelling or cellulitis with systemic symptoms (fever, malaise)
° Rapidly progressing infections such as Ludwig’s angina or deep space infections
° Persistent infections not resolved by local measures alone
° Prophylaxis in patients at risk of infective endocarditis or with immunocompromising conditions

Local dental infections like localized abscesses or pulpitis do not typically require systemic antibiotics and are best managed by definitive dental treatment such as extraction or pulpectomy.

✅ Commonly Recommended Antibiotics and Dosage
For pediatric patients, the most frequently recommended antibiotics are:

° Amoxicillin: 20–40 mg/kg/day divided every 8 hours, or 25–45 mg/kg/day if given twice daily
° Amoxicillin with Clavulanic Acid: Used when beta-lactamase resistance is suspected
° Clindamycin: 8–20 mg/kg/day in three divided doses (for penicillin-allergic patients)
° Azithromycin: 5–12 mg/kg on the first day followed by lower doses over 4 days

Prescribers must adjust dosages based on weight and age and consider the patient’s medical history, including allergies and hepatic or renal function.

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

✅ Antibiotic Prophylaxis
The AAPD, following the American Heart Association (AHA) guidelines, recommends antibiotic prophylaxis for pediatric patients at high risk of infective endocarditis, especially before procedures likely to cause bleeding (e.g., tooth extractions, periodontal surgery). This includes:

° Children with prosthetic heart valves
° Previous infective endocarditis
° Certain congenital heart conditions
° Cardiac transplant recipients with valvulopathy

The standard prophylactic regimen is amoxicillin 50 mg/kg orally one hour before the procedure.

💬 Discussion
Despite clear guidelines, studies reveal frequent antibiotic overprescription in pediatric dentistry. A cross-sectional study by Al-Jundi et al. (2022) indicated that many dentists prescribe antibiotics for non-indicated conditions such as reversible pulpitis, primarily due to parental expectations or time constraints. This inappropriate practice fosters resistance and increases adverse drug reactions, including gastrointestinal issues, allergic reactions, and alterations in the child’s developing microbiome.
Moreover, the COVID-19 pandemic initially led to increased remote consultations and a spike in empirical antibiotic prescriptions, further underscoring the need for robust antimicrobial stewardship programs in dental settings.
Educational interventions, integration of prescribing guidelines into electronic health systems, and continuing professional development can help reduce inappropriate prescribing practices. Collaborative efforts between pediatricians, pharmacists, and pediatric dentists are also essential.

💡 Conclusion
Antibiotic use in pediatric dentistry should be reserved for cases with systemic involvement or significant risk of progression. Adherence to updated, evidence-based guidelines is critical to minimizing resistance and ensuring patient safety. Dental professionals must prioritize definitive treatment over pharmacologic management when possible and engage in continuous education to refine prescribing practices.

Updated Criteria for the Selection of Antibiotic Dosage and Regimen in Dentistry

Antibiotic therapy in dentistry is essential for preventing and treating infections resulting from dental procedures.

📌 Recommended Article :

PDF 🔽 Antibiotics and its use in pediatric dentistry: A review ... Antibiotics are commonly used in dentistry for prophylactic as well as for therapeutic purposes. Very often antibiotics are used in unwarranted situations, which may give rise to resistant bacterial strains

Correct selection of antibiotic dosage and regimen not only ensures therapeutic efficacy but also minimizes the risk of developing bacterial resistance and adverse effects.

✅ A. Determining Factors in Antibiotic Selection

1. Identification of the Etiological Agent
Odontogenic infections are often polymicrobial, predominantly involving anaerobic and gram-positive aerobic bacteria. Precise identification of the causative agent allows for the selection of an antibiotic with an appropriate spectrum. However, due to the difficulty in isolating and culturing these microorganisms in daily practice, empirical selection based on local epidemiology and the nature of the infection is common.

2. Antibiotic Spectrum
The chosen antibiotic should be effective against the most common pathogens in odontogenic infections. For example, amoxicillin is effective against a wide range of gram-positive bacteria and some gram-negative ones, while clindamycin is preferred in patients allergic to penicillins due to its activity against anaerobes and gram-positive aerobes.

3. Pharmacokinetics and Pharmacodynamics
Understanding the absorption, distribution, metabolism, and excretion of the antibiotic is crucial for determining the dosage and frequency of administration. For instance, amoxicillin has good oral bioavailability and a half-life that allows for administration every 8 hours. Clindamycin, on the other hand, requires administration every 6 to 8 hours due to its shorter half-life.

4. Patient's Condition
The patient's systemic conditions, such as renal or hepatic insufficiency, can affect drug elimination, requiring dosage adjustments. Additionally, in immunocompromised patients, more aggressive or prolonged treatment may be necessary.

5. Possible Interactions and Adverse Effects
It is essential to consider drug interactions, especially in polymedicated patients. For example, erythromycin can interact with other drugs metabolized by the cytochrome P450 system, increasing the risk of toxicity. Moreover, some antibiotics can cause gastrointestinal adverse effects or allergic reactions that must be monitored.

2. Amoxicillin/Clavulanic Acid
° Indications: Resistant infections or when beta-lactamase-producing bacteria are suspected.
° Adult dosage: 875 mg/125 mg orally every 12 hours.
° Pediatric dosage: 25–45 mg/kg/day divided into two doses.
° Considerations: The combination with clavulanic acid broadens amoxicillin's spectrum but may increase the incidence of gastrointestinal effects.

3. Clindamycin
° Indications: Patients allergic to penicillins; infections by anaerobes.
° Adult dosage: 300 mg orally every 6–8 hours.
° Pediatric dosage: 8–20 mg/kg/day divided into three or four doses.
° Considerations: Monitor for gastrointestinal side effects and the risk of pseudomembranous colitis.

4. Azithromycin
° Indications: Patients allergic to penicillins; infections by susceptible bacteria.
° Adult dosage: 500 mg once daily for three days.
° Pediatric dosage: 10 mg/kg once daily for three days.
° Considerations: Has a prolonged half-life, allowing for simplified dosing regimens.

✅ C. Conclusions on the Selection of Antibiotic Dosage and Regimen in Dentistry

1. Evidence-Based Selection: The choice of antibiotics in dentistry should be based on the identification of the etiological agent, appropriate antibiotic spectrum, and updated clinical guidelines to ensure efficacy and safety in treating odontogenic infections.
2. Importance of Pharmacokinetics and Pharmacodynamics: Dosage and regimen should be adjusted considering the drug's absorption, metabolism, and excretion, as well as the patient's systemic condition, to avoid overdosing or bacterial resistance.
3. First-Line Antibiotics and Alternatives: Amoxicillin remains the antibiotic of choice for common dental infections, while clindamycin and azithromycin are safe options for patients with penicillin allergies.
4. Avoiding Antibiotic Abuse and Resistance: Empirical prescription should be prudent, considering the increasing bacterial resistance and the impact of indiscriminate antibiotic use on oral and general microbiota.
5. Individualized Treatment: Each patient should receive personalized antibiotic therapy, taking into account their clinical history, drug interactions, and potential adverse effects to optimize therapeutic response and reduce complications.

In conclusion, the rational use of antibiotics in dentistry is essential for effective infection treatment, minimizing risks, and contributing to the fight against microbial resistance.

A. What Is a Dental Infection?
A dental infection, or odontogenic infection, originates within the teeth or surrounding supporting structures and can spread to adjacent tissues if not promptly addressed. These infections typically begin when bacteria infiltrate the dental pulp—the innermost part of the tooth containing nerves and blood vessels—leading to inflammation and the formation of an abscess. Common causes include untreated dental caries (cavities), periodontal disease, or trauma to the tooth.

B. Signs and Symptoms of Dental Infection
Recognizing the early signs and symptoms of a dental infection is crucial for timely intervention. Common indicators include:
° Pain: Persistent, throbbing toothache that may radiate to the jawbone, neck, or ear.
° Sensitivity: Discomfort when consuming hot or cold foods and beverages.
° Swelling: Inflammation in the face or cheek, indicating the spread of infection.
° Fever: Elevated body temperature as the body responds to the infection.
° Swollen Lymph Nodes: Tenderness in the lymph nodes under the jaw or in the neck.
° Difficulty Swallowing or Breathing: Severe cases may lead to swelling that impinges on the throat, necessitating immediate medical attention.
If any of these symptoms are present, it is imperative to seek prompt dental care to prevent the infection from spreading and causing more severe health issues.
