Bezgin 2016.

Methods	RCT, parallel‐arm Teeth randomly assigned Conducted in Turkey. Operator was a paediatric dentist
Participants	16 children, 20 teeth, age range 6 to 13 years, mean age 10.5 years
Interventions	Group 1:Pulpectomy (gutta‐percha/AH‐Plus); n = 10 (1 visit) rubber dam Caries removal prior to pulpal access not mentioned Pulp access with no precision Pulpotomy amputation with no precision Irrigation with 1% sodium hypochlorite and physiological saline Instrumentation with K‐files and barbed broaches Canals were completely filled with gutta‐percha points using a Size 30 master cone and Size 25, 20 and 15 accessory cones applied with finger spreaders sizes 25 and 20 and AH‐Plus Sealer using a cold lateral condensation technique. Final restorations were completed in the same session using reinforced glass ionomer cement and composite resin. Group 2:Pulpectomy (MTA); n = 10 (2 visits) rubber dam Caries removal prior to pulpal access not mentioned Pulp access with no precision Pulpotomy amputation with no precision Irrigation with 1% sodium hypochlorite and physiological saline Instrumentation with K‐files and barbed broaches White MTA was mixed according to the manufacturer’s recommendations, placed in the canal using the MTA Gun System and compacted using endodontic pluggers. The MTA was allowed to set completely by placing a cotton pellet moistened with sterile water inside the pulp chamber and temporarily sealing the access cavity with reinforced glass ionomer cement. After 2 days, the temporary restoration was removed, and the cavities were permanently restored using reinforced glass ionomer cement and composite resin as a final restoration.
Outcomes	Clinical success (no symptoms of pain, tenderness to percussion, swelling, and presence of a fistula or pathological mobility), radiographic success (no evidence of periradicular or interradicular radiolucency or internal or external root resorption): evaluation at 6, 12, 18, 24 and 36 months
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Insufficient information to make a clear judgement
Allocation concealment (selection bias)	Unclear risk	Insufficient information to make a clear judgement
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Insufficient information to make a clear judgement
Blinding of clinical outcomes assessment	Unclear risk	Insufficient information to make a clear judgement
Blinding of radiological outcomes assessment	High risk	Quote: "examiners could not be blinded to the type of the root canal filling"
Incomplete outcome data (attrition bias) All outcomes	Low risk	No missing data
Selective reporting (reporting bias)	Unclear risk	Insufficient information to make a clear judgement
