Primary Outcome Measures:
  • Clinical and radiographical success rates (%) of each treatment group [ Time Frame: 1 year ]

    The outcome of clinical success/failure is determined by subjective symptoms and objective observation of inflammation/infection.

    The outcome of radiographic success is classified by using a modification of the Strindberg criteria.



Secondary Outcome Measures:
  • Patient Assessment of Pain with questionnaire [ Time Frame: 6-months ]
    Pain assessment is carried out using the pain Numerical Rating Scale (NRS) with ratings between 0 to 9. Pain assessment is made up to 7 days. One NRS form is given to each patient to complete.


Enrollment: 302
Study Start Date: March 2012
Study Completion Date: December 2016
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Indirect pulp capping (IPC)
Indirect pulp capping
Procedure: Indirect pulp capping (IPC)

Procedure: IPC

The IPC will be performed as follow:

  • Anesthesia
  • isolation the tooth
  • access to the lesion
  • incomplete removal of carious tissue from the cavity walls
  • indirect pulp capping with ≈2 mm layer calcium enriched mixture cement
  • permanent filling with sandwich technique
Other Name: Indirect pulp capping
Experimental: Direct pulp capping (DPC)
Direct pulp capping
Procedure: Direct pulp capping (DPC)

Procedure: DPC

The DPC will be performed as follow:

  • Anesthesia
  • isolation the tooth
  • access to the lesion
  • complete removal of carious tissue from the cavity walls result in pulp exposure
  • preparation of clot-free pulpal mound
  • direct pulp capping with ≈2 mm layer calcium enriched mixture cement
  • permanent filling with sandwich technique
Other Name: Direct pulp capping
Experimental: Miniature pulpotomy (MP)
Miniature pulpotomy
Procedure: Miniature pulpotomy (MP)

Procedure: MP

The MP will be performed as follow:

  • Anesthesia
  • isolation the tooth
  • access to the lesion
  • complete removal of carious tissue from the cavity walls result in pulp exposure
  • intentionally removal of pulp horn (≈1 mm)
  • preparation of clot-free pulpal mound
  • direct pulp capping with ≈2 mm layer calcium enriched mixture cement
  • permanent filling with sandwich technique
Other Name: Miniature pulpotomy
Experimental: Full pulpotomy (FP)
Full pulpotomy
Procedure: Full pulpotomy (FP)

Procedure: FP

The FP will be performed as follow:

  • Anesthesia
  • isolation the tooth
  • access to the lesion
  • complete removal of carious tissue from the cavity walls result in pulp exposure
  • pulpotomy
  • preparation of clot-free pulpal mound
  • direct pulp capping with ≈2 mm layer calcium enriched mixture cement
  • permanent filling with sandwich technique
Other Name: Full pulpotomy

Detailed Description:
The purpose of this randomized clinical trial is to demonstrate the effect of four methods of Vital Pulp Therapy (VPT) using a new endodontic bio-material [calcium enriched mixture (CEM) cement] in pain relief as well as clinical/radiographic success, for management of irreversible pulpitis of human permanent teeth.
