Cemento-ossifying fibroma: A South American multicenter study.
Article in Medicina oral, patologia oral y cirugia bucal, 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
backgroundCemento-ossifying fibroma (COF) is a benign odontogenic fibro-osseous neoplasm with the proliferation of a cellular fibrous stroma. This study aimed to characterize the clinicodemographic, radiographic, and therapeutic profile of COF in Brazil, Colombia and Venezuela. MATERIALS AND
methodsEight oral pathology and oral medicine services participated. Clinical, radiographic and treatment-related data were retrieved from patient records. Diagnoses were established according to the 5th edition of the WHO classification of odontogenic and maxillofacial bone tumors. Data were analyzed descriptively.
resultsA total of 112 cases were included; 44.6% were from Brazil and 27.7% each from Venezuela and Colombia. Most individuals were female (n=97; 86.6%), with a mean age of 35.6±12.6 years. Posterior mandibular involvement predominated (n=47; 65.3%). Mixed radiographic patterns were most frequent (n=46; 50.0%), and cortical expansion was observed in 52.7% (n=48). Complete surgical removal of the lesion without prior incisional diagnosis and enucleation/curettage were the most common management approaches (n=69; 61.6%). Recurrence occurred in 8.3% of individuals with the available follow-up.
conclusionsThe study offers the first multicenter documentation of COF in South America, corroborating prior literature regarding its predilection for women in the third to fourth decades of life and for posterior mandibular sites. Subtle clinicodemographic variants were noted across the three countries.
