Evaluation Of Laser Versus Conventional Pulpotomies In Mature Molar Teeth With Irreversible Pulpitis

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.
