Summary
The Corneal point (SC) is a stable reference point for cephalometric measurements, comparable to the SN plane. This study validates its use in standard and 3D photography for growth analysis.
Area of Science:
- Dentistry
- Orthodontics
- Anthropometry
Background:
- The Corneal point (SC) is a skin landmark.
- Its stability during growth is crucial for its use as a reference point.
- Measurements can be taken from standard and 3D photographs.
Purpose of the Study:
- To provide scientific evidence for using the Corneal point (SC) as a reference point in cephalometric analysis.
- To demonstrate the stability of the SC point during growth.
- To compare the SC plane with the established SN plane.
Main Methods:
- Analysis of 105 radiographs.
- Descriptive and longitudinal statistical analysis.
- Cross-sectional and longitudinal study design.
Main Results:
- The SC plane exhibits inter-subject variability in millimetric values.
- The relationship between SN and SC values was analyzed.
- No significant sex-based differences were found between SC and SN variations.
Conclusions:
- The SC plane demonstrates an overlapping trend with the SN plane in both cross-sectional and longitudinal analyses.
- The SC plane can be considered a reliable reference point for cephalometric measurements.
- This finding is important for understanding age-related changes in craniofacial growth.
