Dental root surface structure as an indicator of age
The Journal of Forensic Odonto-Stomatology
|June 1, 1993
Summary
A new method assessing tooth root surface roughness (SRS) shows promise for estimating age, correlating significantly with age across various teeth. While not reliable alone, SRS can enhance multiple regression models for more accurate age determination.
Area of Science:
- Forensic Anthropology
- Dental Age Estimation
Background:
- Accurate age estimation is crucial in forensic and anthropological contexts.
- Existing methods for dental age estimation have limitations.
Purpose of the Study:
- To investigate the relationship between human tooth root surface structure and age.
- To evaluate the utility of root surface structure in age estimation models.
Main Methods:
- Analysis of 1000 human permanent teeth (excluding molars).
- Utilized Surface Roughness Scores (SRS), Gustafson's (RG), and Johanson's (RJ) scoring systems.
- Statistical analysis using SPSS, including Pearson correlation.
Main Results:
- Pearson correlations between age and RJ/RG were low, indicating limited value for age estimation.
- Correlations between age and SRS were significant for all teeth, ranging from 0.44 to 0.68.
- No influence of gender or extraction reason on root surface structure was detected.
Conclusions:
- The new Surface Roughness Scores (SRS) show potential for improving dental age estimation.
- SRS is currently too subjective and lacks reproducibility for sole use in age estimation.
- SRS can be a valuable addition to multiple regression methods for age estimation.
