fa Prevalence of talon cusps in a Portuguese population: Forensic identifi cation signifi cance of a rare trait بیماری های دهان Oral Medicine پژوهشي Research <b> Background</b>: 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. <div>  <b>Materials and Methods:</b> 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.</div><div><b> Results:</b> 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). </div><div>  <b>Conclusion:</b> 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.</div><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Dental Research Journal </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://drj.mui.ac.ir/index.php/drj/article/view/1540" target="_blank"><font color="#0000ff">Full Text</font></a></p> Dental anatomy, forensic anthropology, forensic odontology, forensic science,human identifi cation, talon cusps 0 0 http://idai.ir/browse.php?a_code=A-10-32-3424&slc_lang=fa&sid=1 Ricardo Jorge Simões 100319475328460015703 100319475328460015703 No Departamento de Medicina Dentária Forense, Faculdade de Medicina Dentária da Universidade do Porto, Hugo F.V.
