Sexual Dimorphism Determination by Piriform Aperture Morphometric Analysis in Brazilian Human Skulls
Provedor de dados: 77
Autores: Cantín López,Mario; Suazo Galdames,Iván Claudio; Zavando Matamala,Daniela Alejandra; Smith,Ricardo Luiz.
The sex determination of human skeletons is important in forensic and anthropological research. It can be carried out through qualitative or quantitative analysis of morphological parameters of dimorphism. The shape of the piriform aperture is one of the classic indicators of sexual dimorphism since it describes differences between males and females according to strong population-specific behavior. The purpose of this study was to analyze the presence of sexual dimorphism in the size of the piriform aperture and its relationship with individual skin color. We used 90 human skulls from the Collection of the Federal Universidad de Sao Paulo (UNIFESP), with registered data on sex, age and skin color (classified as white, black and brown). The dimensions...

Autores: Suazo Galdames,Iván; Cantín López,Mario; López Farías,Bernarda; Sandoval Marchant,Catherine; Torres Muñoz,Sebastián; Gajardo Rojas,Patricio; Gajardo Rojas,Marcelo.
The study investigates the presence of sexual dimorphism in the size of the permanent teeth among Chilean individuals. Mesiodistal and bucolingual diameters were measured in the teeth of 150 patients between 18 and 24 years old, 67 males and 83 females (excluded were third molars and pieces with large cavities and fillings). The largest were found in males; the differences in mean bucolingual diameters with p&lt;0.05 were observed in pieces 1.1, 1.2, 1.3, 1.6, 1.7, 2.6, 3.3, 4.1, 4.2, and 4.5; and with p &lt;0.01, the relevant pieces were to 4.4 and 4.7. With regard to mesiodistal dimensions, the only significant difference p &lt;0.05 was found in piece 1.2. These results show that sexual dimorphism can be found in all group teeth.

Autores: Hermosilla Venegas,Valeria; San Pedro Valenzuela,Jaime; Cantín López,Mario; Suazo Galdames,Iván Claudio.
Establish a person's identity can be a very complex process, one of the main objectives of the forensic sciences. The analysis of the teeth, fingerprints and DNA comparison, are probably the most used technics, allowing fast and secure identification processes. However, these techniques can not always be applied, in some cases, it is necessary to apply different and less known techniques. In this work, a systematic analysis of the shape and dimensions of the palatal rugae was performed. We analyzed 120 subjects of both sexes, between 15 to 20 years olds, fully dentated, and by calcorrugoscopy were determined the shape, size, number and position of the palatal rugae. The most prevalent palatal rugae shape was sinuous (43%) followed by curve (27%), line...
