390 - Non-syndromic Radiculomegaly and Concurrent Anomalies: A Case-series

Introduction: Radiculomegaly (RM) is defined as an increased root-crown ratio of teeth ( >2.5X). RM is a rare finding that is associated with oculofaciocardiodental, Klinefelter, and Cockayne syndromes. Non-syndrome RM is exceptionally rare. There are very few cases on non-syndromic, generalized RM affecting primary or permanent dentition.

Case-series: This case-series (IRB approval #21-2981) discusses three pediatric cases of RM and associated developmental anomalies detected on panoramic radiographs. In these discussed cases, RM was associated with number and shape anomalies such as hypodontia and gemination, respectively. One of the surprise findings was that all the three RM cases were associated with bifid mandibular canal.

Conclusion: Panoramic radiographs are vital for detecting RM and associated anomalies in children. RM may have implications on endodontic, orthodontic, and surgical management of a patient. Hence, this case-series provides details of clinical implications of RM and appropriate anticipatory guidance for care.
