Summary
Dens invaginatus, a dental anomaly, can affect tooth development and may be associated with impacted mesiodens. Cone-Beam Computed Tomography (CBCT) is crucial for detailed morphological assessment of these complex dental anomalies.
Area of Science:
- Dentistry
- Oral and Maxillofacial Radiology
- Developmental Biology
Background:
- Dens invaginatus (DI) is a developmental anomaly resulting from enamel organ invagination into the dental papilla.
- DI can present with other dental abnormalities, like dysmorphic mesiodens, often incidentally found on conventional radiography.
- Conventional radiography has limitations in visualizing the complex 3D morphology of DI.
Observation:
- A 9-year-old girl presented with an impacted mesiodens.
- Pre-surgical examination using Cone-Beam Computed Tomography (CBCT) revealed three coronal invaginations within the mesiodens.
- These intricate invaginations were not discernible through conventional radiographic methods.
Findings:
- CBCT imaging provided a detailed three-dimensional morphological analysis of the impacted mesiodens with dens invaginatus.
- The study highlights the superior diagnostic capability of CBCT for complex dental anomalies.
- Microscopic reproductions and radiographic images facilitate collaborative research and educational purposes.
Implications:
- CBCT is essential for accurate diagnosis and pre-surgical planning of complex dental anomalies like DI.
- Understanding the morphology of DI through advanced imaging aids in better patient management.
- This case underscores the importance of advanced imaging techniques in pediatric dentistry and orthodontics.
