Arrested Mesiodens Within the Nasopalatine Canal on Pre-Orthodontic Evaluation

9-year-old male

01

The Finding

A 9-year-old male was referred for routine pre-orthodontic CBCT assessment. The radiologist identified an arrested mesiodens located within the nasopalatine canal, causing enlargement of the incisive foramen, a very rare anatomic presentation. The radiologist noted that this finding is clinically significant as it would likely be overlooked or misinterpreted on two-dimensional imaging, yet has important implications for orthodontic planning, surgical procedures, and risk of neurovascular involvement. Three-dimensional imaging was essential for accurate localization and characterization of this uncommon finding.
