Conservative treatment of a horizontal root fracture at the bone margin of a mandibular central incisor: a case report.
Article in Journal of medical case reports, 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
backgroundRoot fractures occurring close to the bone margin have a poor prognosis. Although conservative treatment is preferred, it presents considerable challenges. This report describes the successful use of two types of mineral trioxide aggregate materials for conservative treatment of horizontal cervical root fractures. CASE PRESENTATION: A 25-year-old Japanese woman experienced root fractures of the mandibular central incisor due to trauma. At the initial visit, the crown of the tooth on the labial side was fractured above the gingival margin, and the root on the lingual side was fractured near the bone margin. The fractured tooth structure was bonded with methyl methacrylate-based resin cement, and the gap was filled with a mineral trioxide aggregate material, a resin-modified mineral trioxide aggregate material, and a methyl methacrylate-based adhesive resin cement. The tooth was successfully preserved through the use of multiple fiber post reinforcements, minimal periodontal surgery, bleaching, and composite resin filling.
conclusionThe treatment approach applied in this study, using appropriate materials and surgical procedures, successfully preserved the tooth with horizontal root fractures near the alveolar bone, which are considered difficult to treat. This case suggests that appropriate material selection and meticulous treatment procedures can enable successful tooth preservation.
