Dental Article 🔽 Zinc Oxide Eugenol in Dentistry: Is It Still Used in Modern Clinical Practice? ... Zinc oxide eugenol (ZOE) has been a cornerstone material in dentistry for over a century due to its sedative properties, ease of manipulation, and low cost.

💬 Discussion
While CTZ and TAP exhibit broad antimicrobial properties, their routine use in pediatric endodontics is increasingly questioned. Modern minimally invasive techniques combined with mechanical debridement and bioceramic materials may reduce the need for antibiotic pastes.
The balance between antimicrobial effectiveness and biological safety remains critical. Evidence suggests that high antibiotic concentrations are unnecessary and potentially harmful.
Furthermore, antimicrobial stewardship initiatives discourage the overuse of antibiotics in any clinical context, including localized intracanal therapy.

🎯 Clinical Recommendations
▪️ Avoid routine use of antibiotic pastes in primary teeth when conventional pulpectomy techniques are feasible.
▪️ Consider alternative intracanal medicaments such as calcium hydroxide when appropriate.
▪️ If antibiotic paste is used, employ minimal effective concentrations.
▪️ Avoid minocycline-containing formulations in esthetic zones.
▪️ Follow antimicrobial stewardship guidelines.

✍️ Conclusion
CTZ paste and triple antibiotic paste present significant clinical limitations, including antimicrobial resistance risk, tooth discoloration, cytotoxic effects, and safety concerns. Although they retain selective indications in specific cases, their indiscriminate use in pediatric dentistry is not supported by contemporary evidence. Safer, biologically compatible alternatives should be prioritized whenever possible.

This article analyzes the most common prescribing mistakes in pediatric dental infections, explains their clinical consequences, and provides evidence-based corrective strategies.

✅ Most Frequent Errors in Pediatric Dental Antibiotic Therapy

1. Prescribing Antibiotics Without Clear Indication
One of the most prevalent errors is prescribing antibiotics for:

▪️ Localized irreversible pulpitis
▪️ Localized apical abscess without systemic involvement
▪️ Dental pain without infection

Evidence demonstrates that definitive operative treatment (e.g., pulpotomy, pulpectomy, extraction) is sufficient in these cases. Antibiotics should be reserved for infections with:

▪️ Fever
▪️ Facial cellulitis
▪️ Lymphadenopathy
▪️ Systemic symptoms
According to the American Academy of Pediatric Dentistry, antibiotics are adjuncts, not substitutes, for dental treatment.

2. Incorrect Weight-Based Dosing
Pediatric dosing must be calculated in mg/kg/day, divided appropriately. Common errors include:

▪️ Using adult doses in adolescents without weight verification
▪️ Under-dosing, leading to subtherapeutic levels
▪️ Over-dosing, increasing toxicity risk

For example:
▪️ Amoxicillin: 20–45 mg/kg/day
▪️ Clindamycin: 10–25 mg/kg/day
