1 · What the graph read from it

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.

2 · The registry

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

backgroundApical periodontitis in the anterior region is often accompanied by aesthetic defects, and its clinical management requires concurrent consideration of functional recovery and aesthetic rehabilitation. This report presents a rarely reported procedure combining endodontic microsurgery (EMS) and crown lengthening surgery (CLS) for anterior teeth with coronal defects and apical lesions. CASE PRESENTATION: This report presents two cases of residual crowns with apical periodontitis in the anterior region, for which a well-organized and coordinated multidisciplinary treatment protocol was implemented. Following detailed clinical assessment and meticulous treatment planning, a combination of EMS and CLS was performed simultaneously. EMS effectively controlled infection and promoted osseous healing, while CLS optimized the gingival contour and clinical crown length. More than six months after the combined surgery, the final prosthesis was delivered. The follow-up results for over one year confirmed that the affected teeth were clinically asymptomatic and exhibited incomplete healing radiographically in both cases, and also confirmed the stability of the crown lengthening surgery and restorative results.

conclusionsThese cases demonstrate the advantages of EMS combined with CLS in treating complex affected teeth in the anterior aesthetic zone, eradicating infection, and facilitating rapid osseous healing. This approach may serve as a clinical reference for the preservation of similar complex anterior teeth in aesthetic zones.
