Maintaining dental pulp vitality is the ultimate goal in conservative restorative dentistry and endodontics.
When pulp exposure occurs due to deep caries, traumatic injuries, or mechanical preparation, clinicians face a critical decision: proceed with invasive root canal treatment or attempt a biological preservation procedure.
Direct pulp capping (DPC) leverages the intrinsic repair capacity of pulpal tissue to induce inflammation resolution and promote mineralized tissue barrier formation.
However, achieving predictable long-term clinical success requires far more than simply placing a capping agent over an exposed pulp.
In the comprehensive review "Direct pulp capping procedures – Evidence and practice" (published on PubMed Central), authors Rafiqul Islam et al. synthesize current biological evidence, material evolution, and critical clinical protocols to bridge the gap between scientific theory and daily practice.
From traditional calcium hydroxide to advanced hydraulic calcium silicate cements (bioceramics/MTA), this paper outlines an evidence-based roadmap for preserving pulpal integrity and ensuring predictable restorative outcomes.
Key Scientific & Clinical Highlights Covered
✔ Intrinsic Pulpal Healing & Defense: Understanding the cellular mechanisms of pulp repair, including stem cell recruitment, dynamic dentin bridge formation, and the imperative role of controlling pulpal inflammation before capping.
✔ Biomaterials Evolution: Comparing time-tested Calcium Hydroxide (Ca(OH)2) with modern Hydraulic Calcium Silicate Cements (MTA and Bioceramics)—evaluating bioactivity, sealing ability, marginal adaptation, and mechanical stability.
✔ Prognostic Factors for Clinical Success: Analyzing critical determinants that influence long-term outcomes, including patient age, pulpal health status, exposure site and size, hemorrhage control, and bacterial isolation.
✔ Aseptic Workflow & Microleakage Control: Emphasizing strict rubber dam isolation, magnification, antibacterial rinsing, and providing a hermetic, leak-proof permanent coronal restoration to prevent bacterial microleakage.
✔ Future Perspectives in Vital Pulp Therapy: Exploring emerging trends in tissue engineering, growth factors, and anti-inflammatory biomaterials designed to enhance pulpal healing and mineralized barrier creation.
Mastering modern direct pulp capping protocols empowers clinicians to move away from unnecessary extirpative therapies, delivering biological, tooth-preserving treatments that stand the test of time.
