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

Bilateral gemination of permanent maxillary central incisors is a rare developmental dental anomaly, with a prevalence of approximately 0.04% in permanent dentition. This case report describes a 12-year-old boy presenting with enlarged central incisors, featuring incisal notches and causing palatal displacement of adjacent lateral incisors due to space encroachment. Cone-beam computed tomography (CBCT) revealed 2 distinct root canals with divergent apices in the right incisor and a single bean-shaped canal in the left, with no periapical pathology. These findings highlight CBCT's critical role in mapping complex pulpal anatomy for accurate diagnosis. The condition predisposes teeth to plaque retention, increasing risks of caries and gingival inflammation. Management requires a multidisciplinary approach, including conservative enameloplasty, restorative procedures, or orthodontic intervention to address aesthetic and functional challenges. Further research is needed to refine treatment protocols and explore the etiology of such anomalies.
