Microsurgical Intervention for Dens Invaginatus in an Immature Tooth: A Case Report With Long-Term Follow-Up.
Article in Case reports in dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Dens invaginatus (DI) is a rare dental anomaly characterized by the infolding of enamel and dentin into the pulp cavity during tooth development. This condition often leads to complex endodontic challenges, predisposing affected teeth to caries, pulp necrosis, and chronic periapical abscesses. This case report describes the successful management of a maxillary lateral incisor with Type II DI complicated by a chronic periapical abscess, using an endodontic microsurgical approach. A 10-year-old girl presented with a chief complaint of recurrent swelling in the maxillary left incisor area. Clinical examination revealed a malformed maxillary left lateral incisor with Grade II mobility and a fluctuant gingival swelling. Periapical radiography and cone-beam computed tomography (CBCT) confirmed DI with an immature apex, significant periapical rarefaction, and fenestration of the labial cortical bone. Endodontic microsurgery treatment was performed, involving flap reflection, lesion excision, root canal irrigation with 1% sodium hypochlorite (NaOCl), and retrofilling using a calcium-silicate-based sealer (CeraSeal) and bioceramic putty (CeraPutty). The surgical site was sutured, and postoperative care instructions were provided. Histological examination confirmed a periapical cyst. Follow-up examinations revealed favorable soft tissue healing, mucosal sinus tract closure, and complete bone regeneration at the surgical site. CBCT evaluation at 3 years confirmed full buccal bone regeneration. This case demonstrates that endodontic microsurgery can be a successful treatment option for managing complex DI cases with chronic periapical abscesses when orthograde endodontic treatment is not feasible. CBCT imaging plays a pivotal role in diagnosis, treatment planning, and postoperative assessment. Further clinical research is warranted to evaluate the long-term outcomes of microsurgical management in similar developmental anomalies.
