A study comparing the effectiveness of three biologically compatible materials (Bio-C Repair, NeoPUTTY and Mineral Trioxide Aggregate) for the treatment of milk teeth with serious decay that is close to or affecting the nerve inside but can be saved

INTERVENTION: Intervention1: Various Biomaterials as pulpotomy agents: Three biomaterials will be Compared and evaluated for their efficacy based on their clinical and radiographic outcomes as pulpotomy agents in deciduous molars in pediatric patients. Control Intervention1: Bio‐C Repair: Bio‐C Repair is an established Biomaterial but it has not yet been used as a pulpotomy agent in primary teeth Control Intervention2: NeoPUTTY: NeoPUTTY is an established material but its studies as a pulpotomy agent in primary molars are limited. Control Intervention3: Mineral Trioxide Aggregate: Mineral Trioxide Aggregate is an established material as a pulpotomy agent and AAPD recommends its use in pediatric molar pulpotomy procedures. CONDITION: PRIMARY OUTCOME: To compare and evaluate the efficacy of Bio‐C Repair, NeoPUTTY, and Mineral Trioxide Aggregate (MTA) as pulpotomy agents in primary molars.Timepoint: at 1, 3, 6 and 9 months post opertaively. SECONDARY OUTCOME: 1. To evaluate the efficacy of Bio‐C Repair as a pulpotomy agent in primary molars. ; 2. To evaluate the efficacy of NeoPUTTY as a pulpotomy agent in primary molars. ; 3. To evaluate the efficacy of Mineral Trioxide Aggregate (MTA) as a pulpotomy agent in primary molars. ; 4. To compare the efficacy of Bio‐C Repair, NeoPUTTY, & Mineral Trioxide Aggregate (MTA) as pulpotomy agents in primary molars. ; Timepoint: at 1, 3, 6 & 9 months post opertaively. INCLUSION CRITERIA: 1. Healthy and cooperative children in the age group of 4‐8 years. 2. No history of spontaneous or persistent pain. 3. Restorable primary molars with deep carious lesions approximating or reaching the pulp. 4. No pain on percussion 5. No pathological mobility 6. No Periodontal ligament widening as seen in the radiograph 7. No pathological internal or external root resorption. 8. No apical or furcal radiolucency. 9. Hemostasis achieved within 5 minutes of coronal pulp amputation.
