Summary
Palatal vault growth in children is significant during primary and mixed dentition. Palatal surface area measurements are more reliable for assessing these growth modifications than palatal volume.
Area of Science:
- Pediatric dentistry
- Craniofacial growth
- Dental morphology
Background:
- Understanding palatal vault development is crucial for diagnosing and treating dental anomalies.
- Assessing growth modifications requires reliable measurement parameters.
Purpose of the Study:
- To evaluate changes in the palatal vault in children over time.
- To assess the reliability of palatal surface area and palatal volume in measuring growth modifications.
Main Methods:
- 26 healthy children (5.3 ± 0.3 years) were followed for 30 months.
- 3D digital models of dental casts were created using laser scanning.
- Palatal surface area and volume were measured, and effect size (ES) coefficients were calculated.
Main Results:
- Significant increases in palatal surface area and volume were observed (P < .001).
- Palatal surface area showed higher ES coefficients than palatal volume.
- Only palatal surface area at 30 months exceeded the diagnostic reliability threshold (ES ≥ 1.0).
Conclusions:
- The palatal vault shows significant growth during the primary and mixed dentition stages.
- Palatal surface area is a more reliable parameter than palatal volume for assessing individual growth modifications.
