Teeth will be anesthetized then Rubber dam and high suction will be used in pulpotomy procedure. Cavity outline will be performed by sterile #330 high speed bur using water spray. Caries will be removed by large spoon excavator. When pulpal exposure occurred, the roof of pulp chamber will be removed by low speed round bur. Haemostasis will be obtained by applying pressure with a moist cotton pellet with saline. Then the test materials will be 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

Radiographic evaluation will be performed immediately after teeth restoration (baseline radiograph), then after three, six, and twelve months for the furcation radiolucency area and bone radiodensity. A photo-simulated phosphorus plate sensor was used to take direct standardized digital radiographs. The parallel periapical technique was obtained by Rinn, which is attached to the X-ray tube with its arm fastened to the film holder that contained a coated PSP (photo-stimulated phosphorus plate). To ensure standardization during radiographic film retakes, condensation rubber base impression material will be positioned on the outside of the film holder, and the child is told to bite on it while the material is set. The sensor wil exposed to an X-ray machine (Planmeca ProX, Helsinki, Finland) with a central ray perpendicular to the sensor at 70 kVp, 6 mA, and 0.8 s. Radio-densitometric and radiometric analysis of the radiographs will be performed by RadiAnt software.
