Detailed Description

Pulpotomy is the most widely accepted technique for treating primary teeth with deep carious lesion, pulp exposure during the operatory process or after a traumatic pulp exposure. Mineral trioxide aggregate (MTA) is one such material that has shown tremendous potential for regeneration. Biodentine™ (hydraulic silicate cement) is a novel dental material with high mechanical characteristics as well as superior biocompatibility and bioactive behaviour. Nowadays, chicken eggshell powder (CESP) (a natural calcium-rich source) is achieving wide acceptance in the medical and dental fields. To date, there is insufficient evidence to properly evaluate Eggshell Powder as a pulpotomy agent in primary teeth; thus, the current study aimed to assess and compare clinical and radiographical success of Eggshell Powder, Biodentine and MTA as pulpotomy agents in primary teeth.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: group II: biodentine
30 primary molars will be treated with biodentine to cover pulp stumps
Procedure: pulpotomy
Teeth will be anesthetized then Rubber dam and high suction will be used in pulpotomy procedure. Cavity outline was performed by sterile #330 high speed bur using water spray. Caries was removed by large spoon excavator. When pulpal exposure occurred, the roof of pulp chamber removed by low speed round bur. Haemostasis was obtained by applying pressure with moist cotton pellet with saline. Then the test materials was applied. after that, pulp stumps of all molars in each group will be dressed using Intermediate restorative material then the tooth will be restored with a preformed stainless steel crown
Radiation: cone beam computed tomography (CBCT) assessment
a post-operative CBCT image will be taken immediately after completing the procedure with fixed exposure parameters (120 Kv, 5mA, and 0.125mm voxel size) using the smallest field of view (8D, 8Hcm) also, after 12 months follow-up periods.
Active Comparator: group III: mineral tri-oxide aggregate (MTA)
30 primary molars will be treated with MTA to cover pulp stumps
Procedure: pulpotomy
Teeth will be anesthetized then Rubber dam and high suction will be used in pulpotomy procedure. Cavity outline was performed by sterile #330 high speed bur using water spray. Caries was removed by large spoon excavator. When pulpal exposure occurred, the roof of pulp chamber removed by low speed round bur.

Experimental: group 1: Eggshell Powder
30 primary molars will be treated with Eggshell Powder freshly mixed with distilled water till it reaches a suitable consistency (1:1 ratio by volume) to cover pulp stumps
Procedure: pulpotomy
Teeth will be anesthetized then Rubber dam and high suction will be used in pulpotomy procedure. Cavity outline was performed by sterile #330 high speed bur using water spray. Caries was removed by large spoon excavator. When pulpal exposure occurred, the roof of pulp chamber removed by low speed round bur.
