Guided tissue regeneration (GTR) with barrier membrane (resorbable or non-resorbable) vs Open flap debridement (access flap surgery): Hard tissue probing at surgical re-entry (bone gain)
- Population
- Patients with chronic periodontitis (aged 21 years or older) with periodontal infra-bony defects; furcation-involved teeth and aggressive periodontitis excluded
- Intervention
- Guided tissue regeneration (GTR) with barrier membrane (resorbable or non-resorbable)
- Comparison
- Open flap debridement (access flap surgery)
- Outcome
- Hard tissue probing at surgical re-entry (bone gain)
Guided tissue regeneration (GTR) with barrier membrane (resorbable… led to higher hard tissue probing at surgical re-entry (bone gain) compared with open flap debridement (access flap surgery); GRADE not reported.

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
