Background: Dental techniques are frequently used in human identifi cation some of those include
comparative analyses of dental features that, being rare or unique to an individual, can establish
a positive identifi cation. The usefulness of each feature depends on its population, frequency, and
uniqueness. The aim of this study was to determine the prevalence of talon cusps in a Portuguese
population.
Materials and Methods: A prospective study was performed. Three hundred and two patients
were studied, and talon cusps presence was assessed. Statistical tests were carried out using Statistical
Package for the Social Sciences (SPSS) 17 software (SPSS Inc., Chicago, IL, USA). Statistical analysis
relied primarily on descriptive statistics and crosstabs, with Chi-square analysis.
Results: Results showed that talon cusps were observed in only 6.3% of patients. The maxillary
lateral incisors were the most common teeth showing this feature (82.1% of all teeth).
Conclusion: It can be concluded that talon cusps are an uncommon trait in these Portuguese
population, and therefore, it is a feature that can be potentially very useful in forensic human
identifi cation, when antemortem dental records are available.
