✅ Introduction
Antibiotic therapy in pediatric dentistry plays a crucial role in the management of acute odontogenic infections, including pulpitis, abscesses, and cellulitis. These conditions often involve rapid bacterial proliferation, tissue inflammation, and pain, demanding timely and targeted pharmacological intervention. However, indiscriminate use of antibiotics contributes to microbial resistance and adverse effects, highlighting the importance of updated, evidence-based prescription guidelines.

✅ Definition of Acute Infections
Acute dental infections are characterized by sudden onset, rapid progression, and short duration, typically involving bacterial invasion of dental or periodontal tissues. They are usually caused by polymicrobial flora dominated by Streptococcus spp., Prevotella, and Fusobacterium species. Clinically, they manifest as pain, swelling, erythema, and occasionally systemic symptoms such as fever or lymphadenopathy.

✅ Mechanisms of Action of Antibiotics in Dentistry
Antibiotics used in pediatric dental practice act via specific mechanisms targeting bacterial survival and replication:

▪️ β-lactams (e.g., amoxicillin, penicillin V): Inhibit bacterial cell wall synthesis, leading to lysis.
▪️ Macrolides (e.g., azithromycin, erythromycin): Inhibit protein synthesis by binding to the 50S ribosomal subunit.
▪️ Clindamycin: Blocks peptide bond formation at the 50S ribosomal site; effective against anaerobes.
▪️ Metronidazole: Disrupts bacterial DNA synthesis in anaerobic organisms.

Understanding these mechanisms is key to selecting the appropriate antibiotic based on infection type and microbial profile.

✅ Common Acute Infections in Pediatric Dentistry

1. Acute Apical Abscess: Localized pus accumulation due to pulp necrosis and bacterial invasion of periapical tissues.
2. Cellulitis: Diffuse bacterial infection extending through soft tissues; requires immediate antibiotic therapy.
3. Pericoronitis: Inflammation of soft tissue around erupting teeth, especially mandibular molars.
4. Periodontal Abscess: Rapid destruction of periodontal ligament and alveolar bone caused by anaerobic bacteria.
5. Postoperative Infections: Following dental extraction or trauma, often involving mixed aerobic-anaerobic flora.

Prompt identification and antibiotic therapy prevent complications such as facial swelling, osteomyelitis, and systemic spread.

✅ Updated Protocols for Antibiotic Therapy
Current guidelines from the American Academy of Pediatric Dentistry (AAPD, 2024) and British National Formulary for Children (BNFc) recommend:

▪️ Use antibiotics only when infection has systemic involvement or spread beyond local tissue.
▪️ Avoid prophylactic or empirical antibiotic use without clinical indication.
▪️ Prefer narrow-spectrum antibiotics such as amoxicillin for first-line therapy.
▪️ Consider allergy alternatives like clindamycin or azithromycin.
▪️ Adjust dosing by weight and infection severity.

💬 Discussion
Recent studies emphasize the importance of precision antibiotic prescribing to mitigate resistance. For instance, substituting amoxicillin-clavulanate for simple amoxicillin is not always justified unless β-lactamase-producing organisms are suspected. Furthermore, combining local drainage and antibiotic therapy yields superior outcomes compared to antibiotics alone. Pediatric dentists must balance clinical urgency and microbial stewardship when treating acute infections.

✍️ Conclusion
Updated antibiotic protocols in pediatric dentistry aim to ensure efficacy, minimize bacterial resistance, and safeguard child health. Judicious selection, proper dosage, and adherence to evidence-based guidelines are essential. Continuous professional education remains vital to promote rational antibiotic use.

🔎 Recommendations

▪️ Prescribe antibiotics only after clinical and radiographic evaluation.
▪️ Amoxicillin remains first-line for most odontogenic infections.
▪️ Clindamycin or azithromycin are preferred in penicillin-allergic patients.
▪️ Combine antibiotic therapy with drainage or debridement when indicated.
▪️ Educate parents on completing prescribed courses to avoid resistance.

📊 Comparative Table: Common Antibiotics in Acute Dental Infections

Antibiotic	Mechanism / Route	Adult Dose	Pediatric Dose
