Summary
Early radiographic evaluation for unerupted cuspids is crucial. Most maxillary incisor resorption occurs in the midroot and may not be visible on standard periapical radiographs.
Area of Science:
- Dentistry
- Radiology
- Orthodontics
Background:
- Unerupted cuspids can cause resorption of adjacent maxillary incisors.
- Early detection of incisor resorption is important for timely orthodontic intervention.
Purpose of the Study:
- To investigate the characteristics and radiographic detectability of maxillary incisor resorption caused by unerupted cuspids.
Main Methods:
- Radiographic analysis of 46 cases with unerupted cuspids and maxillary incisor resorption.
- Detailed examination of resorption location and surfaces.
Main Results:
- Maxillary incisor resorption predominantly occurred in the midroot region.
- Approximately 50% of resorption was on labial or lingual surfaces, undetectable by periapical radiography.
- Resorption was observed early in the process.
Conclusions:
- Early radiographic assessment of cuspid position (by age 10-11) is recommended to identify potential incisor resorption.
- Standard periapical radiographs may underestimate the extent of incisor resorption due to unerupted cuspids.
