🎯 Recommendations
▪️ Administer 4–8 mg dexamethasone preoperatively for optimal
▪️ Consider submucosal injection for convenience and localized effect
▪️ Combine with NSAIDs (e.g., ibuprofen) for multimodal analgesia
▪️ Avoid routine use in patients with systemic contraindications
▪️ Educate patients regarding expected outcomes and minimal risks

✍️ Conclusion
Dexamethasone is an effective and safe adjunct in third molar surgery, significantly reducing pain, swelling, and trismus. Evidence supports its preoperative administration at doses of 4–8 mg, with multiple routes offering comparable outcomes. Its integration into clinical protocols enhances patient recovery and postoperative satisfaction.

✅ Introduction
Odontogenic infections are typically polymicrobial, involving aerobic and anaerobic bacteria, predominantly Gram-positive cocci and anaerobic rods. While penicillin derivatives have long been first-line agents, contemporary guidelines favor drugs with broader coverage and improved pharmacokinetics.
Penicillin G remains pharmacologically significant, but its clinical utility in dentistry has become more selective.

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 Characteristics of Penicillin G
Penicillin G (benzylpenicillin) is a beta-lactam antibiotic that acts by inhibiting bacterial cell wall synthesis, leading to cell lysis.

Key characteristics:
▪️ Primarily effective against Gram-positive organisms
▪️ Limited activity against beta-lactamase–producing bacteria
▪️ Poor oral bioavailability (acid-labile)
▪️ Short half-life, requiring frequent dosing
▪️ Administered mainly via parenteral routes (IV/IM)
