The primary clinical objective has shifted from traditional apexification toward Regenerative Endodontic Procedures (REPs), which aim to promote continued root maturation, dentinal wall thickening, and apical closure.
However, achieving complete microbial control without damaging Apical Stem Cells (SCAP) or compromising the structural integrity of thin radicular dentin remains a delicate balancing act.
Selecting the appropriate intracanal medicament—whether Calcium Hydroxide Ca(OH)2, Triple Antibiotic Paste (TAP), or Double Antibiotic Paste (DAP)—is central to the long-term predictability of regenerative protocols.
The landmark systematic review and naïve indirect-comparison meta-analysis published in the International Endodontic Journal (Wiley), titled “The Efficacy of Intracanal Medicaments Within the Regenerative Endodontic Procedures on Permanent Necrotic Immature Teeth: Systematic Review and Naïve Indirect-Comparison Meta-Analysis,” provides a critical, evidence-based evaluation comparing the clinical, radiographic, and biological outcomes of these disinfection modalities.

Key clinical insights highlighted in this comprehensive analysis include:
✔ Triple Antibiotic Paste (TAP): Demonstrates potent, broad-spectrum antibacterial disinfection within the root canal system, but requires strict concentration management to avoid stem cell cytotoxicity and crown discoloration (particularly when containing minocycline).
✔ Double Antibiotic Paste (DAP): Offers a highly effective antimicrobial alternative that eliminates minocycline-induced staining risks while maintaining strong bactericidal action against resistant endodontic pathogens.
✔ Calcium Hydroxide Ca(OH)2: Serves as a biologically favorable, biocompatible medicament that supports stem cell viability and periapical healing, though prolonged application must be balanced against potential reductions in radicular dentin microhardness.
By understanding the comparative efficacy, tissue safety, and biomechanical effects of each intracanal medicament, clinicians can refine their disinfection protocols—balancing microbial elimination with stem cell preservation to achieve predictable regenerative outcomes.
