Protocol summary

Study aim
Comparative evaluation of of MTA and Biodentine in pulp therapy of mandibular primary molar with reversible pulpitis
Design
A parallel-group, double-blind, randomized, phase 2-3 clinical trial on 58 patients. A table of random numbers was used for randomization.
Settings and conduct
In children refer to the specialized children's office in Ilam city for pulp therapy in mandibular primary molar teeth with reversible pulpitis, after preparing the initial radiograph and pulpotomy, the remaining pulp is covered for each patient with using Mineral Trioxide Aggregate (MTA) or Biodentine. After one week, if there are no signs and symptoms of treatment failure, the final restoration is done with Stainless Steel Crown. Clinical evaluation of treatment results at 3, 6, 9, and 12 months and radiographic evaluations are performed at 6- and 12-month periods. The patient and the evaluator of the treatment results will not know what substance was used.

Intervention groups
Intervention A: The remaining pulp is covered with paste MTA. Intervention B: The remaining pulp is covered with paste Biodentine.
Main outcome variables
the percentage of occurrence of pain; sensitivity to precussion; swelling; fistula; pathological mobility; root lucency; internal or external root resorption; Widening of the Periodontal Ligament; bone loss; and lack of lamina dura integrity

General information

Reason for update
According to endodontic and pediatric professors, reversible pulpitis is the correct term.

Randomization (investigator's opinion)
Randomized
Randomization description
In this study, a simple method using random number tables will be used to select people; In this way, first, the order "AB" is considered for the odd number, and the order "BA" is considered for the even number. Then we refer to the table, choose a column randomly and if the first selected number is odd, we use the order "AB"; In this way, the first person in group A will receive MTA treatment and the next person will receive Biodentine treatment spontaneously in group B. In the same way, if the obtained number is even, the "BA" order is taken into consideration and the first person is placed in group B and receives Biodentine treatment, and the next person is automatically placed in group A and receives MTA treatment. This work is repeated for 29 times to obtain 29 samples in each group.
Blinding (investigator's opinion)
Double blinded
Blinding description
Clinical and radiographic evaluations are performed by a person who does not know the type of substance consumed in each group. The patient will not know the type of material used in each tooth.

Intervention groups

1

Description
Intervention group A: First, a periapical radiograph will be prepared from the desired tooth using the standard parallel technique with the help of Rinne XCP (DENTSPLY, USA). Film number zero is used with speed E (Kodak, Ekta speed) or speed F (Kodak, Insigne). Then first local anesthesia with lidocaine 2% and epinephrine (Daropakhsh/Iran) 1:80000 is performed. The decayed crown is removed under sterile conditions using a rubberdam and a No. 4 round slow-speed bur, and in the next step, the roof of the pulp chamber is removed with a 330 high-speed bur along with water, and access to the crown will be completed. Using process bur No. 6, the crown pulp is completely removed from the entrance of the canal and the pulp chamber is washed with normal saline. Hemostasis will be achieved at the coronal pulp excision site at the entrance of the canals using sterile cotton moistened with normal saline for 5 minutes. If hemostasis does not occur, the tooth is excluded from the study. In group A, the remaining pulp is covered with 2 mm of MTA paste (at a ratio of 3 to 1). A layer of zonalin (Golchadent company) is temporarily placed and the patient is visited again seven days later (short term follow up). Before placing the Stainless Steel Crown (SSC), the operator first checks the clinical symptoms, pain, sensitivity to precussion, swelling, mobility and fistula. In the absence of the mentioned cases, the tooth will be repaired with SSC. The patient will not know the type of material used in each tooth.
