Evaluation of Pulpotomy Techniques (Formocresol, Ferric Sulphate, Mineral Trioxide Aggregate) (MTA)

This interventional study will randomly allocate patients in three groups ( Formocresol, Ferric Sulphate , Mineral trioxide aggregate) based on the inclusion criteria procedure will be started by local local anesthesia with 2% lignocaine. Once anesthesia is achieved caries removal and access opening will be done with a round carbide bur number 6 or 8 and 330 respectively. Coronal pulp tissue will be removed by sharp spoon excavator. Hemostasis will be achieved with a sterile cotton pellet soaked with saline.Teeth in which hemostasis could not be achieved with in 5 minutes will be excluded from the study.these initial steps will be same for all three groups wile subsequent steps will varry according to the treatment group.

For formocresol group a sterile cotton pellet soaked with formocrsol will be placed on radicular pulp stumps for 5 minutes and then removed. Later the pulp stumps will be covered by zinoxide eugenol cement and tooth restored with glass ionomer cement.

For ferric suplahte a solution of 15.5% will be applied on sterile cotton and placed on pulp stumps for 15 seconds .later the pulp stumps will be covered by zinc oxide eugenol cement and tooth restored with glass ionomer cement.

For mineral trioxide aggregate pulpotomy pulp stumps will be covered with mineral trioxide aggregate and tooth will be restored with glass ionomer cement.

Patient will then be recalled for follow up at 2 weeks ,1 month and 6 months. Assessment will be done clinically and radiographically to determine treatment sucess and failure.
