Plain English summary of protocol
Background and study aims
A pulpectomy is a procedure that removes infected or diseased pulp (the inside material in a tooth) in order to save the tooth from being pulled. After the pulp is removed, the area inside the tooth is disinfected and then filled with a material. When doing this in young children with their primary (also known as baby) teeth, it is important to do this as quickly as possible in order to not interfere with the child’s development. The pulpectomy treatment could be done in one or two sessions. In a two session procedure, the filling amterial is put in the tooth later. The aim of this study is to see is the procedure will have good results when done in one session as it does in two sessions.
Who can participate?
Children aged two to six years old who require dental treatment in the upper front teeth.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive the treatment in only one session. Those in the second group receive the treatment over two sessions, as they return 30 days after the initial treatment for it to be finalised. Participants are followed up one, two, three, six and 12 months after their treatment to measure the success rates of their treatments.
What are the possible benefits and risks of participating?
Participants may benefit from having their primary teeth treated which allows them to stay in the mouth longer until they naturally fall out. In addition, participants may benefit from free assistance at the pediatric dentistry clinic, with periodic oral health guidelines, which will contribute to the quality of life of their entire family. There may be some risks such as some discomforts related to endodontic techniques may occur, such as sensitivity at the time of anesthesia, discomfort due to anesthetic sensation, adverse reaction causing crying according to the patient, not knowing the procedures used, relative fatigue as a result of the procedure being complex and of greater duration.
Where is the study run from?
Federal University of Santa Maria (Brazil)
When is the study starting and how long is it expected to run for?
August 2016 to May 2017
Who is funding the study?
Brazilian Federal Agency for the Support and Evaluation of Graduate Education, Coordination for the Improvement of Higher Education Personnel, CAPES (Brazil)

| Health condition(s) or problem(s) studied | Endodontic treatment of anterior primary teeth. |
| Intervention | Participants are allocated to one of two groups after opening of brown envelopes, previously organized within a randomised sequence. The intervention group receive local anesthesia (Lidocaine 2%), absolute isolation, chemical-mechanical preparation of the root canals with Milton's solution, second-series endodontic files, final irrigation with saline solution 0.9%, paste filling (Calcium Hydroxide PA + zinc oxide powder and propylene glycol), gutta percha blade and final restoration with composite resin. The control group also receive local anesthesia (Lidocaine 2%), absolute isolation, chemical-mechanical preparation of the root canals with Milton's solution, second-series endodontic files, final irrigation with saline solution 0.9% and paste filling (Calcium Hydroxide PA + zinc oxide powder and propylene glycol), but the restoration is temporary with glass ionomer cement. After 30 days, there is a reintervention in the control group with the exchange of the obturator material, and then the final restoration is done with composite resin. The operator performs blindly during the procedure, since only the group becomes aware of the final moment of use of the sealing paste. The cases have their performances evaluated at 30, 60, 90 days, six months and one year through clinical and radiographic exams. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | Radiographic lesions are measured using the periapical radiography at the beginning and the end of the study. |
| Secondary outcome measures | Fistula is measured using visual scale at the beginning and the end of the study. |
