Group I zinc oxide Neem
preperation: 1\\ A standardized access cavity procedure will be performed using a large sterile round end bur in a high-speed handpiece with copious irrigation, a sharp spoon excavator will remove coronal pulpal tissues then will remove radicular pulp by barbed broach then will be used K files for chemo mechanical preparation (size 15,20,25) with saline (2%) irrigation to remove necrotic pulp tissues then all the canals will be dried using paper points. 2\\ After complete excavation of all pulp tissue, saline irrigation is done then the canals will be obturated zinc-oxide with Neem ( Zinc oxide powder(Prime Dental Pvt. Ltd.Thane, Maharashtra, India) and 100% Neem oil with mixing ratio of 1:3 will be mixed on a glass slab with a stainless- steel spatula) and then the rest of the pulp chamber will be filled with Zinconol. (reinforced zinc oxide eugenol)3\\ Tooth will be restored with stainless steel crown.
Group II zinc oxide eugenol
preperation: 1\\ A standardized access cavity procedure will be performed using a large sterile round end bur in a high-speed handpiece with copious irrigation, a sharp spoon excavator will remove coronal pulpal tissues then will remove radicular pulp by barbed broach then will be used K files for chemo mechanical preparation (size 15,20,25) with saline (2%) irrigation to remove necrotic pulp tissues then all the canals will be dried using paper points 2\\ After complete removed of coronal and radicular pulp zinc oxide eugenol will be manipulated in the ratio of 3:1 (powder: liquid) to obtain semisolid mix.This mix will be placed in the canals. Gentle condensation of the mix will be done in the pulp chamber with a moistened cotton pellet, followed by the application of Zinconol.3\\ Tooth will be restored with stainless steel crown.
