El presente estudio pretende contribuir al debate sobre políticas de cuidados enfocando la mirada en las ciudades latinoamericanas, en esta ocasión específicamente en la Comuna de Santiago de Chile. A partir del diagnóstico cuantitativo de la situación socioeconómica de las y los habitantes de la Comuna de Santiago, y del análisis de las competencias de la administración local en términos de oferta de servicios de cuidado para niños y niñas, personas adultas mayores y personas con alguna discapacidad, se proporcionan recomendaciones para la planificación, la formulación e implementación de políticas urbanas a corto y mediano plazo.

ABSTRACT. Introduction: an in vitro model was used to measure the hydraulic conductance in human dentin discs treated with oxalic acid for 15, 30 or 60 s maintaining the occlusive effect and measuring 7 and 14 days after application. Methods: 45 dentin discs measuring 1 mm thick were obtained from human third molars which were free of caries and in no occlusion; the samples were obtained from patients aged 16 to 30 years. Discs were sorted out into three study groups (n = 15) depending on the time of application of a commercial solution of oxalate-based dentin desensitizer (DD) (BisBlock®) which contains ˂ 5% oxalic acid of 1.5-1.8 pH: in group A the agent was applied for 15 s, in group B it was applied for 30 s, and in group C for 60 s. The hydraulic conductance of each disc was calculated after acid etching, which corresponds to the maximum permeability of discs (100%) after immediate application of oxalic acid, as well as seven and fourteen days of storage in saline solution. The statistical analysis was done with ANOVA test and post-hoc Games-Howell test. Results: 35,46 ± 23.41% in Group A, 36.34 ± 15.88% in Group B and 24.99 ± 14.99% in Group C, showing that the use of DD for 15, 30 or 60 s decreased permeability in a statistically significant manner (p <0.05). Conclusions: DD was effective in reducing hydraulic conductance regardless of application time, but this reduction was temporary only, since after seven days permeability returns to values close to those of baseline.

[ES] El presente trabajo de investigación responde a la demanda social de revitalizar y dar a conocer a las generaciones actuales la polifacética personalidad artística de Carlos Morón. Para ello, se pensó que lo más conveniente era la realización de un trabajo monográfico sobre su peculiar biografía y heterogénea obra que abarcó el retrato, la pintura mural, la de historia, el paisaje, bodegones, costumbrista, escenografía, escultura y el grabado.
