Aspectos metodológicos para el tratamiento estadístico de la infraestructura en América Latina y el Caribe

La disponibilidad de información cuantitativa sobre inversiones en infraestructura es imprescindible para realizar análisis e investigaciones sobre el tema y para que quienes adoptan decisiones de política puedan formular medidas pertinentes, oportunas y sostenibles. La existencia de una base de datos robusta y estandarizada podría facilitar respuestas para varias preguntas cruciales: ¿cuánto debe crecer la inversión en infraestructura para que el PIB crezca, por ejemplo, en un punto porcentual?, ¿cuál es el nivel de la inversión en infraestructura que maximiza el crecimiento?, ¿es sostenible en el largo plazo?, ¿se gasta lo suficiente en mantenimiento o reparaciones?, ¿en cuánto tiempo se espera que una determinada obra de infraestructura tenga el esperado impacto económico y social?, ¿el monto de inversión que se efectúa en infraestructura compensa el agotamiento de otro tipo de capitales?, ¿es apropiada para el desarrollo sostenible la estructura sectorial de la inversión en infraestructura?, en fin, ¿qué porcentaje de las inversiones en infraestructura se originan en rentas y otros beneficios de la extracción de recursos naturales?, entre otros.

Tratamiento Quirúrgico de Mesiodens en Odontopediatría

Supernumerary teeth are a relatively frequent disorder of odontogenesis that can interfere with the development of the germs teeth. This pathology is most common in the maxillary anterior area, called mesiodens, and their prevalence is generally reported to occur more frequently in male than female, in a ratio of 2:1. The aim of this article was to report the clinical procedures performed in the Clinic of Pediatric Dentistry at the Araraquara School of Dentistry when the presence of two mesiodens, radiographically shown, caused retention of permanent anterior teeth, resulting in esthetic and funcional disturb. All the surgical procedures, etiology and the importancy of the early diagnostic for the appropriate treatment was detailed described.

Tratamiento de maloclusión classe II división 1 con el aparato de Herbst tipo férula, después del pico de crecimiento puberal

Malocclusion class II-1, is represented by a high prevalence in Brazil, being something common in orthodontic practice. One of the main characteristics of this malocclusion is jaw retrusion, by what many devices of jaw advance are presented in the literature. Being one of them Herbst's device, which is a functional and fixed device created by Emil Herbst (1905) and updated by Hans Pancherz in the decade of 80s.This device is characterized by keeping the jaw advance in a continuous way, while presenting a less active treatment, leading to an immediate aesthetic impact, and the patient cooperation is not required. To improve the anchoring and prevent the collapse of the apparatus was set up last amended version of it by Dr Raveli quoted as Herbst splint. Recent research indicates the use of this device after the peak pubertal growth, creating an appropriate response condylar. The aim of this work is to show the orthodontist a choice of how to use the splint Herbst in Class malocclusions II-1.

Treatment and complications of orbito-zygomatic fractures

The aim of the present study was to analyze the etiology, type and treatment employed in the orbito-zygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.

Tratamiento de la deformidad facial causada por la hiperplasia condilar: relato de caso

The condylar hyperplasia is an acquired development anomaly, rare, characterized by an excessive and progressive growing, affecting neck, condilar head, body and the mandible bough, provoking an important facial asymmetry. In the article we present a case of male patient, 22-years-old, reclaiming of painful sintomatology in the region of temporomandibular joint and severe facial asymmetry. It was instituted an orthodontic-surgical treatment by means of orthognathic combined surgery and high condilectomy. After six years of post-surgical controlling, the patient is now in a good shape, without recurrence of facial asymmetry and condylar hyperplasia.

Estado actual del blanqueamiento: sigue siendo un tratamiento seguro? review

The demand for cosmetic dentistry, including teeth whitening, has increased in recent years. The home teeth whitening and in-office, are widely used in dental practice. The mechanism by which it works is by oxidation of the chromogenic existing tooth structure. This is an effective and minimally invasive procedure that achieves tooth lighten the color, however, may cause alterations in the enamel surface, such as a dental permeability increase. Another effect caused by this procedure is tooth sensitivity, being the most common side effect, up to 65% of individuals have had a secondary effect at least once during treatment. This sensitivity and gingival irritation caused by bleaching may vary depending on the patient and used bleaching product
