A conceptual regeneration-maintenance decision aid for class II furcation involvement.
Review in Clinical oral investigations, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo introduce a practical, evidence-based and prognosis-oriented conceptual decision aid for the management of Class II furcation involvement, integrating defect-specific regenerative potential with long-term maintenance feasibility. MATERIALS AND
methodsA structured narrative review of the literature on Class II furcation involvement regeneration, prognostic factors, and long-term maintenance outcomes was conducted using PubMed, EBSCO, and Scopus databases. Variables with documented influence on regenerative outcomes or long-term tooth survival were extracted and grouped into two conceptual axes: a Morphological Regenerability Score, capturing defect anatomy, and a Maintenance Accessibility Score, capturing site-related and patient-related factors. Scoring ranges and thresholds were derived from the magnitude and consistency of reported effect sizes.
resultsThe Morphological Regenerability Score integrates five defect-related variables (vertical furcation involvement component, root divergence at crestal bone, furcation entrance width, defect location and root trunk length) with modifiers for mobility, cervical enamel projections, exposed furcation entrance, and enamel pearls, spanning - 5 to 9 points. The Maintenance Accessibility Score integrates seven maintenance-related variables (plaque control, supportive periodontal treatment compliance, smoking, diabetes control, site/operator accessibility, endodontic status and tissue phenotype), spanning 0 to 13 points. Midpoint thresholds (MRS ≥ 5; MAS ≥ 7) define four clinical quadrants guiding case selection between regeneration, staged treatment strategy, non-surgical or resective approaches, and extraction.
conclusionsThe proposed framework consolidates heterogeneous evidence on Class II furcation involvement prognosis and proposed treatment strategies into a single transparent decision aid. Prospective validation is required before routine clinical adoption. CLINICAL RELEVANCE: This framework supports evidence-based, individualised decision-making for Class II furcation involvement based on defect regenerability and long-term maintenance, and highlights modifiable risk factors that should be addressed before attempting regenerative surgery.
