External root resorptions: cone-beam computed tomography assessment and histopathological characterization.

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
backgroundExternal root resorption (ERR) represents a pathological condition of uncertain etiology and variable clinical presentation that can jeopardize the long-term prognosis of affected teeth.
aimThis study aimed to correlate radiological (cone-beam computed tomography - CBCT) and histological findings in three teeth affected by ERR with different localization (apical, middle or cervical), with a focus on the structural changes of the dental hard and soft tissues. MATERIALS AND
methodsTwo monoradicular and one pluriradicular teeth diagnosed with ERR and external cervical resorption (ECR) based on initial periapical radiography were analyzed using CBCT and lesions were measured in all three planes and described after Patel's classification; after extraction∕root amputation, samples were decalcified and processed using standard histological techniques (Hematoxylin-Eosin, van Gieson, Masson's trichrome).
resultsSeveral key features were noticed at the site of resorptive areas: osteoclasts, large multinucleated cells responsible for the resorption of mineralized tissues positioned along the root surface, resulting in the formation of resorption lacunae. Adjacent to the resorptive areas, granulation tissue, with a dense network of capillaries and inflammatory cells, including fibroblasts. Extensive destruction of dentin, cementum, and enamel, presence of fibrous repair, osteoid formation, and dystrophic calcifications were noticed.
conclusionsThe combined radiological-histological evaluation enhances diagnostic accuracy and may guide therapeutic strategies.
