The goal of this clinical trial is to assess the clinical and radiographic success rate of Laser pulpotomy procedure done in immature permanent molars with symptoms indicative of irreversible pulpitis.. The main question it aims to answer is:

whether the combined use of Laser pulpotomy with MTA capping material will provide faster healing with acceleration of complete root formation in immature permanent molars compared to MTA pulpotomy alone?

Participants will:

The coronal inflammed pulp will be carefully amputated to the level of the canal orifices.

Hemostasis will be achieved by gentle placement of a saline-moistened cotton pellet and Placement of capping material will be performed in the study groups.

The post-operative clinical follow up will be done after one week for patient reassurance. Then the postoperative clinical and radiographic follow-up will be scheduled up to twelve months.

Inclusion Criteria:

• Children with an age ranging between 6 to 14 years old with no gender predilection.

  • Children free of any systemic disease or special health care needs.
  • Patients complaining from intermittent or spontaneous, sharp, localized, diffuse, or referred pain.
  • Selected teeth should give long lasting positive responses to cold testing.
  • Soft tissues around the tooth are normal.
  • Periapical radiographs show deep carious lesions.
  • Patients with immature permanent molars (stages 8 and 9) according to Nolla's classification for tooth developmental stage.
  • Periapical index score 1 or 2.
  • Following pulpal amputation, hemostasis could be easily achievable within 5 to 10 minutes with a sterile moist cotton pellet.

Exclusion Criteria:

• Child with bad experience of dental treatment (uncooperative patient).

  • Non-restorable teeth.
  • Negative response to cold testing.
  • Bleeding could not be controlled.
  • Absence of bleeding from any of the canals.
  • Pus discharge through an associated sinus tract.
  • Pulpal calcifications
  • Radiographic signs of internal or external resorption.
