This study used 284 skulls of adult Brazilians, of which 187 were male and 97 female. A study of the cross-evaluation of the diagnostic test was performed; it was a qualitative approach based on visual examination of 16 traditional indicators of morphological sexual dimorphism, where each indicator determined the level of accuracy, sensitivity, predictive values, likelihood ratios, and odds ratio. All indicators studied had high levels of accuracy (84.75­72.89%). The best indicators were found in traits whose formation is related to the insertion and action of major...

The aim of the present study is to analyze the differences in the soft facial tissue thicknesses measured in corpses without fixing, with recent death, and in embalmed corpses. 30 male human corpses were used; they were divided into two groups according to the presence or absence of a conservation method. Fifteen bodies, without any method of conservation, with an average age of 38.6 years (SD 8.37) and Fifteen preserved bodies by means of the intravascular injection technique of fixing conservative solution on the basis of formaldehyde, with an average age of 38.4 years (SD 7.67). In each one of them the thickness was measured in eight medium and six bilateral paramedium landmarks, using the needle-punction method. The descriptive statistical ones were...

Autores: Suazo Galdames,Iván Claudio; Zavando Matamala,Daniela Alejandra; Smith,Ricardo Luiz.
In forensic medicine, diagnosis of sex is the first step in the identification of human skulls. A first approximation is carried out via the qualitative analysis of a series of morphological indicators of sexual dimorphism. Classical studies (Krogman &amp;amp; Iscan, 1986) described 14 indicators for the diagnosis of sex with an accuracy of 90%, and one of these indicators is the shape of the palate. This study analyzed the effect of the loss of teeth on the accuracy of the diagnosis of sex in Brazilians adult skulls, using the shape of the palate as an indicator. We used 98 skulls of adult Brazilians, comprising 35 females and 63 males with an average age of 39.3 years (SD 7.8). The skulls were classified into two groups, namely the fully edentulous...

El canal mandibular recorre este hueso longitudinalmente, relacionándose en su segmento medio con las piezas dentarias molares y premolares. El conocimiento de la relación del canal mandibular con las piezas dentarias y con las corticales mandibulares es de gran importancia para la práctica de la implantología. En el presente estudio se analizan las relaciones de la porción media del canal mandibular con las corticales mandibulares pertenecientes a individuos de sexo femenino, de entre 50 y 65 años, con caracterización antropométrica coincidente con el registro. Se realizaron mediciones en tres niveles del segmento medio (A-B-C). Los resultados muestran que el canal mandibular presenta una forma ovoidea y que sus diámetros disminuyen a medida que desciende...

The changes in the university curriculum have made necessary the vertical and horizontal integration of contents that are taught in morphology sciences. In this study, students of the Morphology and Human Development Module of the cohorts 2006 and 2007 participated. In 2006 the students (n=83) developed the thematic unit of locomotive apparatus in a chronologicaly and sequentially integrated way. In 2007 (n=102) this same unit was developed in a totally integrated way, in form of learning object from the macroscopic, microscopic and embryology perspectives. A theoretical instrument was designed to evaluate the content of the unit, the approaches of validity and reliability were determined (a=0.79), and then, it was applied to the 2006 and 2007 students....
