Are deciduous upper molars and lower canines useful for sex estimation?
Valente, C; Teixeira, A; Oliveira, P; Caldas, IMObjective: This paper investigates whether deciduous upper molars and lower canines have sexual dimorphic features, exploring these teeth' dimensions and the presence of Zuckerkandl's tubercle and Carabelli's cusp on the first and second upper molars. Design: We analyzed 64 pairs of dental plaster casts from 34 females and 30 males aged between 3 and 12 years. We measured the first and second deciduous upper mo...
Are lip prints hereditary? A systematic review
Chaves, T; Azevedo, A; Caldas, IMHereditary lip prints have been studied by several researchers. However, the literature shows no consensus among the scientific community regarding this topic. Therefore, the aim of this study was to conduct a systematic review to gather evidence to clarify whether the surface structure of lip prints is hereditary and, consequently, if a familial relationship between individuals can be established through the a...

Rodrigo, AR; Caldas, IM; Carvalho, B; Azevedo, A; Pereira, MDFLObjetivos: Caracterizar o impacto da atual pandemia de COVID-19 na ansiedade, medo e stress nos profissionais de saude oral. Metodos: Utilizou-se um questionario autoaplicado online que foi enviado, via email, para tres associacoes na area da Medicina Dentaria. As variaveis categoricas foram descritas atraves de frequencias absolutas e relativas. As variaveis continuas foram descritas utilizando a media e o des...
Rugoscopy in human identification: a study in a sample of twins
Braga, S; Sampaio-Maia, B; Pereira, ML; Caldas, IMPalatal rugae patterns can be useful for forensic identification purposes. However, some doubts persist in concerning the pattern singularity in twins. The purpose of this study was to assess palatal rugae pattern singularity in a sample of twins. To do this, the palatal rugae patterns of 19 pairs of monozygotic twins and 47 pairs of dizygotic twins were studied. Our results showed that in monozygotic twins, no...
Sex estimation using the mandibular canine index components
Azevedo, Á; Pereira, ML; Gouveia, S; Tavares, JN; Caldas, IMThe mandibular canine index (MCI) has been described as a suitable methodology for sex estimation in forensic scenarios but there are contradictory reports about its accuracy. Moreover, the two mandibular canine teeth must be available, which is not always a viable option. The aim of this study was to strip the MCI by analyzing the MCI itself and its components, in order to optimize its use for sex estimation. ...
Orofacial Injuries in Children and Adolescents (2009-2013): A 5-Year Study In P...
Vidal, HG; Caldas, IM; Coelho Júnior, LGTM; Souza, EHA; Carvalho, MVD; Soriano, EP; Pereira, ML; Caldas, AF JrThe aim of this study was to verify the prevalence of acts of aggression to the head, face and neck towards victims of Physical Violence against Children and Adolescents (PVCA) who were examined at the National Institute of Legal Medicine and Forensic Sciences Delegation North (INMLCF-DN) in Porto, Portugal. A study was carried out on 2,148 complaints of physical aggression against children and adolescents (0 t...
Chronology of mineralization of the permanent mandibular second molar teeth and...
Fins, P; Pereira, ML; Afonso, A; Pérez-Mongiovi, D; Caldas, IMForensic age estimation frequently relies upon the chronology of mineralization of the third molar teeth. However, even when present, third molar teeth cannot always be used for estimating age in people who are classified as minors. Seconds molars develop earlier and in a more predictable way, and therefore are often more reliable for age estimation in this age group. This study aims to contribute to forensic a...
A new approach to sex estimation using the mandibular canine index
Silva, AM; Pereira, ML; Gouveia, S; Tavares, JN; Azevedo, A; Caldas, IMRao et al.'s mandibular canine index (MCI) is a simple odontometric method which uses the mandibular canine as the key to sex estimation. This index is defined as the ratio between the right canine mesiodistal dimension and the mandibular canine arch width. The aim of this study was to contribute to sex estimation using dental techniques by analysing the MCI efficiency, and to propose a new approach for its use...
Forensic age estimation using the eruption of the second permanent mandibular m...
Marques, MR; Pereira, ML; Caldas, IMLittle is known about the role of the second molar eruption in forensic age estimation; however, in countries where the legal age is 14-years-old, it can provide important information. This study aims to analyse whether the eruption stages of the second mandibular molar can be used for forensic age estimation purposes. The eruption stage of the second left mandibular molar was assessed and correlation between a...
