Summary
Healthy fingernail shapes vary significantly, offering potential for personal identification. This study identified seven distinct shapes in Nigeria, highlighting diversity similar to fingerprints.
Area of Science:
- Dermatology
- Forensic Science
- Anthropometry
Background:
- Limited data exists on healthy fingernail morphology in medical literature.
- Abnormal fingernail shapes are well-documented, but normal variations are understudied.
Purpose of the Study:
- To identify and classify healthy fingernail shapes.
- To determine the prevalence of these shapes in Ibadan, Nigeria.
- To assess the potential of fingernail morphology for personal identification.
Main Methods:
- A study was conducted on 496 individuals in Ibadan, Nigeria.
- Included analysis of four family units and four sets of monozygotic twins.
- Seven gross fingernail shapes were identified and categorized.
Main Results:
- Seven distinct fingernail shapes were identified in the study population.
- Variations were observed within family members; no two individuals had identical shapes.
- Identical twins exhibited no differences in fingernail shape or size on corresponding fingers.
Conclusions:
- Healthy fingernail shapes exhibit considerable diversity.
- Fingernail morphology shows potential for personal identification, comparable to fingerprints.
- Further development is recommended for using fingernail characteristics in identification systems, particularly in African nations.
