Summary

The aim of the present study will compare the impact of sodium hypochlorite irrigation at different concentrations with and without cryotherapy on post operative pain in permanent mandibular molar teeth.

Will cryotherapy combined with sodium hypochlorite irrigation at different concentrations reduce postoperative pain in compared to conventional sodium hypochlorite irrigation during pulpotomy of mandibular molar teeth with symptomatic irreversible pulpitis?

Conditions

  • Postoperative Pain
  • Vital Pulp Therapies

Interventions

PROCEDURE

vital pulp therapy

Endodontic procedure: The procedures will be performed under local anesthesia with Lidocaine 2% and adrenaline 1/100,000. Teeth will be isolated with rubber dam. Caries will be completely removed with a sterile diamond stone (size 2) under an operating surgical microscope. The access cavity will be prepared up to the level of pulp chamber floor using sterile round diamond bur size 2 in high-speed hand piece with coolant.Once the pulp has been reached, a sharp sterile spoon excavator should be used to remove the pulp tissue to the level of the radicular pulp. Hemostasis will be achieved by irrigating the prepared cavity with volume 3ml of irrigant for up to 6 minutes over the pulp stump. If hemostasis cannot be achieved after 6 mins, the tooth should undergo pulpectomy and Root Canal treatment as per the clinician's normal practice.
