Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Insufficient information to make a clear judgement of Yes or No
Allocation concealment (selection bias)	Unclear risk	Insufficient information to make a clear judgement of Yes or No
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Insufficient information to make a clear judgement of Yes or No
Blinding of clinical outcomes assessment	Low risk	Quote: "Independently, two examiners who were blinded to treatment type evaluated the teeth clinically and radiographically."
Blinding of radiological outcomes assessment	Low risk	Quote: "Independently, two examiners who were blinded to treatment type evaluated the teeth clinically and radiographically."
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
