Evaluation of the Success Rate of Pulpotomy Versus to Root Canal Therapy in Management of Mature First Permanent Molars With Irreversible Pulpitis

The teeth were anesthetized with 4% articaine with adrenaline 1/100,000 , isolated under rubber dam , and sterilized using a cotton pellet soaked in 2.5% sodium hypochlorite (NaOCl). Then carious leisons were removed by using a fresh sterile high-speed diamond bur under copious water irrigation. Upon pulp exposed, the cavity was rinsed with 2.5% NaOCl. The other steps of the treatment proceeded accordingly:

The procedure FP involved the removal of all coronal pulp tissue to the canals orifices level through a fresh sterile high-speed diamond bur Hemostasis was accomplished by compressing a cotton pellet soaked in 2.5% NaOCl over the radicular pulp tissue for 5 min. Then, irrigation with amount of sterile 0.9% sodium chloride (NaCl) solution was gently conducted. Once hemostasis was achieved, the radicular pulp tissue was observed as uniformly reddish pink color. Subsequently, a new type of premixed pulp-capping bio c repair ) was prepared according to the manufacturer's instructions, and a 4-mm layer was directly adapted over the radicular pulp tissue, ensuring that there was not any excess materials on the pulp chamber walls. The access cavity was restored with a liner)and composite restoration all completed in a single visit. Then postoperative radiographs were taken.

RCT was conducted in single visit the pulp tissues were removed from all the root canals, identifying and enlarging canal orifices via fanta Gold rotary , determing the working length with an apex locator. The root canals preparation was conducted by rotary nickel-titanium files, irrigated by using 2.5% NaOCl and 17% ethylenediaminetetraacetic acid (EDTA), and disinfected by using Ca(OH)2.

obturation was performed with gutta-percha and biocermaic sealer, using single cone technique.The access cavity was restored with a liner and resin composite restoration during the same appointment while using rubber dam isolation.
