Conventional endodontic dogma held that once the dental pulp exhibited severe symptomatic inflammation, the entire coronal and radicular tissue was inevitably doomed to necrosis.
However, advances in pulp biology, immunology, and bioceramic materials are spearheading a monumental paradigm shift.
Histopathological research demonstrates that pulp inflammation in response to deep carious lesions is compartmentalized: superficial infection and micro-abscesses can be removed, leaving underlying healthy, immunocompetent radicular pulp tissue capable of full recovery and dentin bridge formation.
The comprehensive review published in the Australian Dental Journal (Wiley), titled “Vital pulp therapy for permanent teeth with diagnosis of irreversible pulpitis: biological basis and outcome,” provides a critical, evidence-based roadmap examining how Vital Pulp Therapy (VPT)—particularly coronal and partial pulpotomy—has emerged as a predictable, biologically conservative alternative to conventional RCT.

Key clinical insights detailed in this landmark paper include
✔ Infection vs. Inflammation: Understanding that bacterial infection, rather than inflammation per se, is the true barrier to healing; eliminating superficial infected tissue allows the remaining pulp to mount a reparative response.
✔ The Role of Hydraulic Calcium Silicates: Evaluating the biological superiority of modern hydraulic calcium silicate-based cements (MTA, Biodentine) over traditional calcium hydroxide in releasing bioactive growth factors and inducing mineralized dentin bridges without cell toxicity.
✔ Hemostasis as a Diagnostic Marker: Utilizing time-to-hemostasis following sodium hypochlorite application to directly assess the vascular vitality and reversible inflammatory state of the remaining pulp tissue.
✔ Predictable Long-Term Outcomes: Analyzing high success rates recognized by both the European Society of Endodontology (ESE) and the American Association of Endodontists (AAE), demonstrating that pulpotomy provides rapid pain relief, structural preservation, and long-term vitality.
✔ The Mandate for Coronal Seal: Emphasizing that strict rubber dam isolation and an immediate, impermeable coronal restoration are non-negotiable prerequisites to prevent secondary microleakage and bacterial re-infection.
By integrating these biological concepts and minimally invasive protocols into everyday practice, clinicians can safely preserve structural dentin, maintain tooth vitality, and deliver more cost-effective, biologically driven outcomes for their patients.
