Forensic dentistry age estimation using apps showed high reliability for males but not for females. These digital tools can serve as a helpful auxiliary method in forensic anthropology, particularly for male identification cases.
Area of Science:
- Forensic Science
- Anthropology
Background:
- Forensic Dentistry is crucial for human identification, with age estimation aiding anthropological profiling.
- Modern technology offers new age estimation methods, including software apps utilizing algorithms to minimize subjective bias in facial recognition.
Purpose of the Study:
- To evaluate the efficacy of two distinct age estimation software applications.
- To assess the reliability of these apps in forensic age estimation.
Main Methods:
- The study analyzed a sample of 100 individuals (50 males, 50 females).
- Two specific applications, "How Old Do I Look? - Age Camera" and "How Old Am I? - Age Camera, Do You Look Like in Selfie Face Pic?", were utilized.
- Univariate and multivariate statistical analyses were performed on the collected data.
Main Results:
- The age estimation apps demonstrated high reliability when applied to male participants.
- A significant discrepancy was observed between actual and estimated ages for female participants, indicating a lack of equivalence.
Conclusions:
- The evaluated software applications show promise as supplementary tools for age estimation in forensic contexts, particularly for male individuals.
- Further research may be needed to improve accuracy for female age estimation using similar technologies.
