Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

Element	Planned (methods)	Found (results)
Population	People of any age with oro-antral communications, fistulae, or both caused by dental procedures	22 adults aged 25 to 56 years with established oro-antral communications; 2 participants did not report for follow-up and were excluded (n=20 analysed)
Intervention	Any surgical or non-surgical technique or material used for the management of oro-antral communications, oro-antral fistulae, or both due to dental procedures	Pedicled buccal fat pad flap (n=10); Buccal flap (n=10)
Comparison	Surgical technique A versus B/Non-surgical technique A versus B/Surgical technique versus non-surgical technique/Surgical technique versus no treatment/Non-surgical technique versus no treatment	Buccal flap (n=10)
Outcomes	Complete closure of oro-antral communications, fistulae, or both (assessed clinically and by participant-reported outcomes, by absence of associated signs and symptoms such as nasal regurgitation, pain, inflammation); Adverse effects (such as graft necrosis and rejection, chronic sinusitis due to failure of OACs, OAFs, or both); Time required for healing	Successful (complete) closure of oro-antral communication (n=20)
Study designs	RCTs (excluding quasi-RCTs and cross-over trials)	RCT (n=1)
Timing	Not reported	Trial duration was two years; closure outcome measured at one month after surgery
