El tratamiento de conductos radiculares de dientes deciduos es una práctica fundamental de la odontopediatría que apunta a la conservación funcional de las piezas dentales, siendo un desafío importante la instrumentación correcta en el mínimo de tiempo evitando el estrés en el paciente, acompañantes y operador. Uno de los pasos más complejos al tratar los conductos de las raíces de molares deciduos quienes están programados para su reabsorción fisiológica radica en la instrumentación de su sistema de conductos. Diversas investigaciones in vivo e in vitro, se han ejecutado para demostrar la eficacia y efectividad de la nueva gama de sistema de limas rotatorias para realizar una adecuada instrumentación del canal radicular con resultados clínicos favorables. Estos elementos contemporáneos se ubican a la vanguardia del tratamiento endodóntico especializado por tanto esta r...

En el presente estudio se analizó la discrepancia dimensional entre los conos de gutapercha y las limas tipo k file, los cuales fueron medidos según el calibre, la longitud y la forma de cada instrumento odontológico. El objetivo de la presente investigación fue de determinar la diferencia significativa entre la discrepancia dimensional de los conos de gutapercha y las limas tipo K File en la clínica odontológica San Miguel de Huancayo-2017. El tipo de investigación fue transversal, observacional, de nivel descriptivo comparativo; se tuvo como muestra a 336 conos de gutapercha de cuatro marcas comerciales, teniendo así los siguientes resultados: Si existe discrepancia dimensional de las medidas de los conos de gutapercha con la medida de las limas tipo K- file. (p=0.000); las medias promedios según el calibre de ingreso de los conos de gutapercha es de 17.8 mm, mientras que de l...

La remoción del material de obturación es un paso importante para el éxito de un retratamiento endodóntico. El propósito de este estudio fue comparar la eficiencia de dos diferentes técnicas de instrumentación rotatoria: Protaper Retratarniento y Mtwo retratamiento en la desobturación de conductos radiculares. Se utilizaron 48 primeras molares inferiores de dientes humanos en este estudio, la muestra fue seleccionada aleatoriamente y los especímenes fueron almacenados en solución de agua destilada. La presencia de canales y no obstruidos fueron verificados usando radiovisiografia.

acceptable, then detect the pollution source. It was performed a microbiologicalanalysis of the water of 21 Lima’s beaches and the detections of contamination sources with human feces. The results qualify the water of 33.33% (07) beaches as unacceptable if it is used as indicators of fecal pollution, the total coliforms and fecal coliforms; if it is included Escherichia coli, it reaches to 47.62% (10); and if also it is included Enterococcus it reaches to 66.66%(14). It was demonstrated the existence of domestic sewage discharge in all the beaches considered as unacceptable; in 35.75% (05) with visual inspection; in 14.29% (02) was observed water running with fecal pollution and in 50% (07) by the relation between E. coli and Enterococcus.

Objective: To determine both the prevalence and risk factors of cervical cancer and squamous intraepithelial lesions, with special attention on the preinvasive cervical disease treatment. Design: Prospective, descriptive, non randomized study. Materials and Methods: Study of 120 non randomly selected cases of cervical cytology during 2003, in women attended at Piedra Liza Health Center (San Juan de Lurigancho). In 49 cases, biopsy was performed to confirm both clinical and colposcopic findings. Results: From the 120 cytology cases, 14 (11,5%) were ASC, 67 (56%) L-SIL, 34 (29%) H-SIL, 3 (2,5%) squamous carcinoma, 2 (2%) adenocarcinoma. In the 49 biopsies, 12 cases were L-SIL, 32 H-SIL, 3 invasive squamous carcinoma, and 2 cervical adenocarcinoma, one in situ. Conclusions: Cytology results suggest that squamous intraepithelial lesions and cervical carcinoma have higher prevalence in this s...

The Convictorio of San Carlos from Lima, was an institution founded for the viceregal State in 1769 in substitution of the noted Jesuit noted school that closed after its expulsion in 1767. The time bigger celebrity and duration corresponded to the rectorado of Toribio Rodríguez of Mendoza who directed its cloisters during almost 30 years, until it presented its renouncement before the viceroy Joaquín of Pezuela, due mainly to the economic anguishing situation that happened to this educational institution before the Emancipation. The present article is focused in the «Statute for Convictorio» proposed by Jerónimo of Agüero, document that governed from 1829 to 1839. In this year it coincides with the arrival to the government of this House of Studies of Bartolomé Herrera who observed an ideological concrete address, giving new airs to the political conservative positions, group of ...

Presidential elections are a space of broad public debate, a vent of ideological passions, confrontation of ideas, among other aspects that we can find thanks to the press diffusing role, responsible for describing occurred events. It is important to point out that newspapers played a central role, especially during pre-electoral contexts or in actual elections, either to forge the image for or against a candidate. On this matter, information contrast from various newspapers and even the memories of prefects, witnesses of the time among other sources, allowed us to approach reality objectively and thus demystify the so-called Aristocratic Republic (1899-1919) labeled by some historians as a space of social and political stability. On the contrary, what is exposed in the press shows us a time of great tension and confrontation at the dawn of the 20th century. An example is 1899 presidenti...

In recent years, intercultural popular fusion music in Lima has grown into a representative «national» genre where intersocial and interethnic interactions take place challenging the established segregation of Peruvian society. This music seems to provide a space where youths contest their historical antagonistic role in Lima looking for cultural transcendence and spiritual meaning, searching for their own popular tradition, their own sacred, themselves.Based on diverse case studies, this article explores the sometimes contradictory discourses of fusion musicians when describing their music, as well as the issues they highlight as important to address through their intercultural projects. Moreover, it will examine the potential of fusion music as a means to enable interclass and interethnic interactions, in which the young white upper classes seek to recreate «the self» and...

This study examines the adoption of administrative and technological innovations in Lima’s optical sector through a descriptive qualitative approach, based on semi-structured interviews and analysis using ATLAS.ti. The findings reveal progress in organizational management, driven by strategic planning, clear structures, and participatory leadership, as well as the use of technologies to monitor productivity. On the technological front, continuous training, personalization and diagnostic tools, process automation, and the integration of ICTs stand out as means to enhance customer service. However, economic and technical barriers—such as high investment costs and uncertainty about results—continue to hinder full digital transformation. In summary, the study provides evidence of how optical businesses in Lima are incorporating innovations to strengthen their competitiveness, operation...

Combining part of the extensive literature on the literary production of Clorinda Matto de Turner with a feminist ideological framework, this article examines the ideology of gender constructed in relation tomodernity, gender policies and national imaginary in two of his short stories, “Pálida!... pero es ella...! Novela homeopática con pretensiones espiritistas” and “Amor de redondel. Cuento a modo de novela”. This ideology, superficially, presents instabilities and contradictions. However, it is through these apparent contradictions that Matto de Turner could manage her reformist program around gender and national reform without apparently altering the hegemonic rule.
