this clinical trial is evaluating the outcome of laser assisted pulpotomy compared to conventional pulpotomy in mature teeth with symptomatic irreversible pulpitis (SIP) assessed by CBCT followed by automated segmentation using Artificial intelligence (AI).

Sixty human permanent molar teeth having irreversible pulpitis will be selected. Teeth will be randomly divided into 3 groups according to the type of pulpotomy; Group A: Photobiomodulation (PBM) pulpotomy, Group B: photocoagulation pulpotomy and Group C: Conventional pulpotomy which will serve as control. All 3 groups will be capped with bioceramic putty material. Post operative pain will be assessed at 24, 48 and 72 hours then after one week using numerical rating scale (NRS). Clinical and radiographic assessment using periapical radiograph of the healing progress will be done simultaneously during the follow up at one, three, six and 12 months intervals. CBCT will be done immediate postoperative and at the end of the follow up period to assess the dentin bridge formation and for automated segmentation to assess the radicular pulp volume changes.

Inclusion Criteria:

• Permanent molar teeth with symptomatic irreversible pulpitis.
• The patient should be ≥ 16 to 50 years old.
• Teeth should give positive response to cold testing and clinical diagnosis of SIP with or without periapical rarefaction.
• Teeth will be selected only if they are restorable.
• Patient medically healthy and free from systemic diseases. ASA I, II.
• patients who agreed to participate in the study to attend the control visits.
• Teeth with periapical index score (PAI) 1 and 2 will be selected

Exclusion Criteria:

• Teeth with necrotic pulp, resorption or subgingival caries.
• Teeth with open apices.
• Medically compromised patients.
• Pregnant patients.
• Patients with uncontrollable bleeding from the radicular pulp.
• Patients with (PAI) score 3-5 will be excluded from the study
