Efecto de represas del río Biobío, en el aporte de sílice fluvial a la costa marina adyacente (Golfo de Arauco).
(Universidad de Concepción.Facultad de Ciencias Naturales y Oceanográficas, 2010)
Ríos y estuarios influencian radicalmente las características físicas, químicas y biológicas de la costa marina adyacente, mediante la modificación e intercambio de materia orgánica y nutrientes. Entre los nutrientes ...
After bleaching enamel remineralization using a bioactive glass-ceramic (BioSilicate)
(2016-01-01)
Tooth bleaching agents may weaken the tooth structure, therefore, it is important to minimize any risks of enamel and dentine damage caused by them. In this way, different materials have been used to avoid or minimize the ...
Evaluation of Physicochemical Properties of a New Calcium Silicate–based Sealer, Bio-C Sealer
(2019-01-01)
Introduction: Calcium silicate–based materials have been proposed as root canal sealers for root canal treatment. The aim of this study was to evaluate the physicochemical properties of a new calcium silicate–based sealer ...
