For each participant, two sets of opaque, identical envelopes were prepared. In the first set, one envelope was labeled “R” (right) and the other “L” (left), indicating the side of the mouth. In the second set, one envelope was labeled “1” and the other “2”, representing the two intervention groups: Cold Ceramic and CEM cement. At the time of treatment, each participant was asked to randomly select one envelope from each set. The envelope drawn from the first set determined the tooth side (right or left) to be treated, while the envelope from the second set determined which material would be used on that side. Consequently, the opposite side received the alternative material. This method ensured that the assignment of the materials to each side was randomized and unbiased for each patient. The entire process was conducted by an independent operator not involved in the clinical procedures or outcome assessments, Blinding description: Due to the similarity of the preparation steps and the appearance of the two materials, the child participating in the study was unaware of the material used. After the study, the teeth treated with Cold Ceramic were named Group A and the teeth treated with CEM Cement were named Group B, and their results were reported to the statistician, as a result of which the statistician was unaware of the nature of each group. N/A Pulpotomy of primary teeth. Intervention 1: Intervention group: Pulpotomy with CEM Cement. Intervention 2: Intervention group: Pulpotomy with Cold Ceramic.
