La exposición gingival excesiva es una condición conocida como sonrisa gingival. Esta alteración genera en muchos casos insatisfacción y solicitud de tratamiento por parte de los pacientes. Este exceso de exposición gingival podría obedecer a diferentes etiologías como un exceso maxilar en sentido vertical, un labio superior corto e hipermóvil, la erupción pasiva alterada, la extrusión dentoalveolar en el sector anterior o la combinación de estas causas. El enfoque de tratamiento va a depender del diagnóstico, de la complejidad del caso y de las expectativas de cada paciente. Por lo tanto, las rutas terapéuticas principales son el alargamiento de corona clínica, el reposicionamiento labial, la cirugía ortognática o la aplicación de toxina botulínica. Para ello, se debe considerar las ventajas y limitaciones de cada tratamiento estético, para garantizar predictibilidad y éxito.

The Rio Grande de Loíza basin of Puerto Rico is the largest on the island, composed of 15 sub-basins. These rivers are contaminated with pathogens related to Communities Without Sanitary Sewerage denominated ComSAS, which use defective septic tanks or direct discharges to water bodies. The Federal Environmental Protection Agency describes it as the highest priority for attention. The research raises the objective of developing a geospatial model to be incorporated into the process of compliance with the Clean Water Act. It includes the design of an ad hoc methodology, which selects the environmental factors and establishes the parameters to prioritize the areas by level and type of risk. The multi-criteria analysis incorporated the geographic information layers including structures/km2, the proximity to rivers, the classification of land use, and the presence of type D hydrologic soil group. The result generated the shapefile layer that identifies 27 % of the study area as high and very high risk. State and federal agencies will be able to incorporate this innovation tool into the decision-making process to quickly assess high-risk communities.

Evaluación crítica de las nociones de “fracaso” y “primera ola,” “descolonización” y/o “postcolonialismo” a ambos lados del Atlántico Norte. Tenemos dos maneras académicas distintas de trabajar dichos interrogantes: las propias de historiadores de postrimerías del período colonial y de principios de la época nacional con un foco en la zona andina (Mark Thurner), y la de los “culturalistas post-estructuralistas” (John Beverley) que cuestionan la incomodidad disciplinar, los fundamentos del quehacer histórico, y que siguen tirando de la literatura en algunos casos. Ambas modalidades se enmarcan en “América Latina,” dentro de los Estudios de Areas Extranjeras con sus impulsos civilizatorios o geopolíticos, tal y como los gestionan las naciones-estados más influyentes, los EE. UU. y el Reino Unido entre otras, con sus respectivas universidades. Se mencionan los temas sobresalientes y los enmarques de ambos autores. Se incluyen las problemáticas de la institución de la universidad estadounidense y británica en relacion a las “lenguas modernas” (o las “humanidades extranjeras o incluso extranjerizantes”) en unos momentos de fuertes incertidumbres y angostamientos innegables.

In the Republic of Paraguay, there is a digital gap between the elderly and the rest of the population, which makes the former suffer from a limitation in relation to access to information technologies, and within these; to Internet. The work consists of a documentary review article that studies, compiles, and reflects on doctrinal, scientific and legal information, putting them in perspective, in light of the Constitution of the Republic of Paraguay and international human rights law, also doing a comparative study between Paraguay and other Latin American countries. Although in Paraguay the Constitution guarantees the validity of the rights of the elderly, in reality it can be observed that access to these technologies is restricted. However, according to the principle of equality and non-discrimination, the State

In this article, we present and discuss the case of Isidora Gual as a way to study the relationship between psychology and society in the last decade of the XIX century. We provide an overview of the cultural and social conditions during Isidora's life and the debates about her actions in print media and the court. Gual became the object of medical, anthropological, psychological, and moral discourses after the body of her dead son was found. This tragedy sparked intense debates among those trying to explain her child's death. Isidora's case reveals how medicine, the law, and Puerto Rican culture attempted to explain the mind during the XIX century.

The article The Biological Sciences course from the College of General Studies: Notes on the first five years of the 1950's and guidelines towards the future is an essay based on research on the origins of the Department of Biological Sciences (DCIBI) of the College of General Studies of the University of Puerto Rico at the Río Piedras campus. It addresses the philosophy, curriculum and teaching-learning processes that distinguish it.  The essay is documented with a wide and diverse collection of primary and secondary references. We intend to carry out institutional research, in addition to providing the sociological critique that allows integrating the context in which the origin and development of the DCIBI takes place in confrontation with important problematic axes through which the 'General Education Movement' and the Faculty of General Studies itself go through.

Local identities have strongly resurfaced at the dawn of the 21st century, a situation that can be contradictory and paradoxical to those who have fully accepted the idea of a globalized world. However, the local identities that are being built, or have come out of their state of hibernation; they are signs of cultural resistance to global designs. This article aims to open the discussion of this topic, by showing local identities in a different way as they have been treated: as supports of national identity and spaces for citizenship in the framework of multicultural relations. Rather, local identities are presented as manifestations of cultural resistance that provide sufficient contributions in the construction of a possible scenario of interculturality. For this purpose, in this writing, it begins with a revisit to the concept of identity, cultural identity and its relationship with culture and collective memory. This article is also a call for social researchers to study local identities with a sense of belonging in an adverse context for the humanities.
