| Loth & Henneberg (1996) described a simple morphological feature for sex determination by observing the flexure of the posterior margin of the mandibular ramus, at the level of the plane occlusal. The purpose of this study is to analyze the level of agreement for determining the sex by observing the parameters described by Loth and Henneberg, in ortopantomography of totally dentate Chilean young adults. This study is based on 188 files of ortopantomography acquired from the Department of Radiology of the Dental School of Universidad de Talca, Chile. In brief, our studies indicated that in the ortopantomography of females 63.25% (62-64.5%) was correctly sexed, whereas the prediction accuracy was only 48.25% (46.550%) for men. The success... |

| 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<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 <0.01, the relevant pieces were to 4.4 and 4.7. With regard to mesiodistal dimensions, the only significant difference p <0.05 was found in piece 1.2. These results show that sexual dimorphism can be found in all group teeth. |

| 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... |

| La proporción áurea es una relación matemática que se establece entre dos estructuras, representada numéricamente como 1 es a 1,618. Esta proporción se encuentra presente en la naturaleza y en la arquitectura de la región cráneofacial. En el presente estudio se analizaron las relaciones de proporcionalidad entre rectas formadas por la unión de puntos anatómicos reproducibles y otros antropométricos, identificándose aquellas que se relacionaban de manera áurea. Para ello, se identificaron 20 puntos anatómicos reproducibles medianos y paramedianos, en 10 cráneos humanos con características antropológicas homogéneas. Las rectas obtenidas por la unión de los puntos fueron relacionadas matemáticamente, para identificar las que establecían relaciones áureas. Se... |

| La determinación de los estilos de aprendizaje (EA) ha sido una preocupación pedagógica permanente, indicando la forma en que cada estudiante estudia y aprende, permitiendo modificar el diseño y la implementación de los procesos de aprendizaje, haciéndolos más eficaces en la formación de un profesional de la salud. En el presente estudio se analizaron las diferencias de los EA en un grupo de alumnos de Kinesiología, medidos en el primer y último años de su Carrera profesional. Se diseñó un estudio exploratorio descriptivo longitudinal cuantitativo mediante la aplicación del Cuestionario de EA Honey-Alonso (CHAEA) en estudiantes de Kinesiología, Universidad de Talca. Un primer análisis de los estilos de aprendizaje fue realizado en 48 estudiantes, el primer... |

| El término efecto Mozart comienza a utilizarse a partir de los trabajos de Rauscher et al. (1993), quienes observaron mejores resultados en tareas que requerían orientación temporo-espacial en estudiantes universitarios. El objetivo de este estudio es analizar el efecto que tiene en el aprendizaje práctico de la anatomía la aplicación de estímulos musicales relacionados con el denominado efecto Mozart. Participaron 254 estudiantes de las carreras de Odontología, Fonoaudiología y Tecnología Médica. Los grupos de estudio fueron sometidos durante toda una Unidad temática a estimulación auditiva utilizando el primer movimiento de la Sonata para dos Pianos en D Mayor (K. 448) de Mozart, los grupos controles desarrollaron su actividad práctica sin estimulación... |

| Melatonin secretion from mammalian pineal glands is regulated by light stimulation by means of a complex neuroanatomical pathway that includes the retina, hypothalamic suprachiasmatic nucleus, intermediolateral nucleus of the thoracic spinal cord, and finally, the superior cervical ganglia. The purpose of this study was to analyze the changes in the pinealocytes and the blood vessel density of the pineal gland after eliminating photic stimulation in rats. Thirteen adult Sprague-Dawley rats were divided into 2 groups, Group I acted as control, and Group II was subjected to a retinal lesión, by means of alcohol injected bilaterally to both ocular bulbs. After 3 weeks, the glands of both groups were processed with hematoxilin-eosin (HE) and observed with an... |

| 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.... |

| The nasal form is one of the most important aspects in assessing the facial aesthetics. Several authors have described changes in the form and nasal dimensions attributable to race and gender. The purpose of this study was to analyze the presence of sexual dimorphism in various morphometric parameters of the nose in a group of Chilean adults. This study involved 180 adults Chilean volunteers, 90 males and 90 females, between the age of 18 and 30 years which were conducted measurements of 12 parameters using indirect anthropometry, based on photographs from the front, profile and the nasal base, standardized, prosecuted through the program Corel Draw Graphics SuiteX3. Of the 12 dimensions nasal analyzed, significant differences were found between males and... |

| 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... |

| La terapia con láser de baj a potencia ha demostrado tener propiedades analgésicas antiinflamatorias, bioestimulantes y promotoras de la respuesta tisular al daño. El propósito de este estudio fue determinar el efecto que el láser de baja potencia tiene sobre el hueso alveolar dañado. Se utilizaros 13 ratas Sprage Dawley, en las cuales se realizó una lesión estandarizada del hueso alveolar, posterior a lo cual una muestra aleatoria de 7 ratas fue sometida a un protocolo de irradiación de 6 J/cm2, tres veces por semana durante cuatro semanas. Las muestras obtenidas del sitio lesionado en ratas expuestas y no expuestas a la terapia fueron procesadas para hematoxilina eosina, contabilizándose el número de osteonas al microscopio óptico con aumento de 40x. Los... |
