Epidemiological and Clinical Features of Regional Odontodysplasia in South Korean Pediatric Patients: A Multicenter Case Series Study.
Article in International journal of paediatric dentistry, 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
backgroundRegional odontodysplasia (RO) is a rare developmental dental anomaly with unknown prevalence. Current knowledge is largely limited to individual case reports.
aimThis study aims to present epidemiological data, clinical features, and radiographic characteristics of pediatric and adolescent patients with RO in South Korea.
designIn this multicenter cohort study, we prospectively and retrospectively recruited participants from 11 university dental hospitals. Patients aged < 19 years diagnosed with RO were included in this study. In prospective cases, epidemiological information, family history, and clinical and radiographic data were collected after obtaining parental consent. All data were anonymized and stored using a study-specific data management system.
resultsAge at diagnosis ranged from 2 to 12 years, with a higher incidence in males. RO was more commonly observed in the maxilla, and all patients exhibited delayed eruption and development. The treatment approaches vary widely and include observation, extraction, pulp therapy, crown restoration, prosthetic rehabilitation, and orthodontic treatment.
conclusionThis multicenter study provides the first comprehensive dataset on RO in Korean children and adolescents. These findings will contribute to the development of clinical guidelines and inform future healthcare policies for the management of rare dental anomalies.
