Oliveira 2013a.

Methods	RCT, parallel‐arm Teeth randomly assigned Conducted in the Paediatric Dentistry Department, University of São Paulo, Brazil. Operators not mentioned
Participants	45 children, 45 teeth, mean age not mentioned, age range 5 to 9 years
Interventions	Group 1:Pulpotomy (CH); n = 15 (1 visit) Rubber dam Caries removal prior to pulpal access with round bur Pulp access with high‐speed and round carbide burs Pulpotomy amputation with excavator For haemostasis, no precision Irrigation with saline CH placed with no precision Group 2:Pulpotomy (MTA); n = 15 (1 visit) Rubber dam Caries removal prior to pulpal access with round bur Pulp access with high‐speed and round carbide burs Pulpotomy amputation with excavator For haemostasis, no precision Irrigation with saline MTA (0.16 g powder mixed with sterile saline to obtain a homogeneous paste) Group 3:Pulpotomy (PC); n = 15 (1 visit) Rubber dam Caries removal prior to pulpal access with round bur Pulp access with high‐speed and round carbide burs Pulpotomy amputation with excavator For haemostasis, no precision Irrigation with saline PC (0.16 g powder mixed with sterile saline to obtain a homogeneous paste)
Outcomes	Clinical success (no spontaneous pain, no swelling, no fistula or no mobility), radiological success (no evidence of furcation radiolucency, no internal root resorption, dentine bridge formation), intra‐canal obliteration, inter‐radicular bone destruction, intra‐canal obliteration: evaluation at 6, 12 and 24 months (at tooth level)
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computerised random‐number generator
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	Low risk	Quote: "...each check‐up involved a clinical... examination of the pulpotomized teeth, which was performed by two blinded and previously calibrated investigators"
Blinding of radiological outcomes assessment	Low risk	Quote: "...each check‐up involved a... periapical radiographic examination of the pulpotomized teeth, which was performed by two blinded and previously calibrated investigators"
Incomplete outcome data (attrition bias) All outcomes	High risk	Proportion of missing outcomes > 10% children randomly assigned
Selective reporting (reporting bias)	Unclear risk	Insufficient information to make a clear judgement
