|
Interventions | Partial wound closure versus complete wound closure Group A (n = 20 teeth): sutures on attached gum only Group B (n = 20 teeth): complete suture was performed on free and attached gums Procedures performed under local anaesthetic, both teeth extracted in same session by same surgeon. Follow‐up: days 3, 7, and 15, and 3 months |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Quote: "2 groups were established on randomised basis (by allotment)" Comment: method of sequence generation not described |
Allocation concealment (selection bias) | Unclear risk | Not mentioned |
Blinding (performance bias and detection bias) patient | Low risk | Double‐blinded |
Blinding (performance bias and detection bias) assessor | Low risk | Double‐blinded; assumed that both participants and clinical outcome assessor blinded to treatment |
Incomplete outcome data (attrition bias) All outcomes | Low risk | All randomised participants included in outcome evaluation. |
Selective reporting (reporting bias) | Unclear risk | All planned outcomes reported. |
Other bias | Unclear risk | No other sources of bias identified. |
