Non-Syndromic Generalized Radiculomegaly: A Brief Pediatric Case Series

Abstract

Background: Radiculomegaly is an idiopathic root malformation characterized by abnormally long tooth roots and, consequently, an increased root-crown ratio of teeth. Although radiculomegaly is rare, non-syndromic radiculomegaly is highly rare. There are no reports of non-syndromic, generalized radiculomegaly affecting both primary and permanent dentition in pediatric patients. Description: This case series presents two unique pediatric cases of non-syndromic, generalized radiculomegaly affecting both primary and permanent dentition. Panoramic radiographs during mixed and permanent dentition were used to calculate root-crown ratios of all teeth to diagnose radiculomegaly. Concurrently, both cases also presented with hypodontia and gemination. These concurrent findings may point to an association of radiculomegaly with other specific tooth anomalies. This case series discusses diagnosis, management, and anticipatory guidance for individuals with radiculomegaly. Conclusion: Panoramic radiographs are vital for efficient diagnosis of radiculomegaly as such a diagnosis will impact future endodontic, orthodontic, and surgical management.
