Chemical composition and bioactivity potential of the new endosequence BC Sealer formulación hiflow
Aim To evaluate in a laboratory setting the effects of Endosequence BC Sealer HiFlow (Brasseler USA, Savannah, GA, USA), a novel calcium silicate-based sealer developed for use in warm canal filling techniques, on human periodontal ligament stem cells (hPDLSCs). Methodology Eluates of EndoSequence BC Sealer HiFlow (BCHiF) (Brasseler USA), EndoSequence BC Sealer (BCS) (Brasseler USA) and AH Plus (AHP) (Dentsply DeTrey GmbH, Konstanz, Germany), were placed in contact with hPDLSCs. The characterisation of the chemical elements of the root canal sealers was assessed using Scanning Electron Microscopy and Energy Dispersive X-ray analysis (SEM-EDX). Inductively Coupled Plasma Mass Spectrometry (I…
Comparative biological properties and mineralization potential of three endodontic materials for vital pulp therapy: Theracal PT, Theracal LC, and Biodentine on human dental pulp stem cells (hDPSCs)
Introduction: The aim of this study was to assess the biological properties and mineralization potential of the new Theracal PT (Bisco Inc, Schaumburg, IL) compared with its predecessor Theracal LC (Bisco Inc) and the hydraulic silicate-based cement Biodentine (Septodont, Saint-Maur-des-Fosses, France) on human dental pulp stem cells (hDPSCs) in vitro. Methods: Standardized sample discs were obtained for each material (n 5 30) together with 1:1, 1:2, and 1:4 material eluates. Previously characterized hDPSCs were cultured with the different materials in standardized conditions, and the following assays were performed: a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, a wo…
Biocompatibilidad y Bioactividad de nuevos materiales para Odontología Regenerativa
Diversas situaciones patológicas dentales pueden verse beneficiadas de un tratamiento que favorezca la regeneración tisular. Las resorciones radiculares, las perforaciones iatrogénicas, la patología infecciosa periapical y las lesiones traumáticas de los dientes se asocian a una pérdida de tejido óseo peridentario. Los tratamientos restauradores convencionales pueden eliminar las circunstancias etiológicas con materiales que no solo sean biocompatibles sino que sean bioactivos. Un aspecto especial es el de la patología que afecta al complejo dentino-pulpar, la parte vital del diente. Se trata de un tejido similar al hueso (una zona mineralizada y otra no) pero con una distribución celular d…
Sleep apnea and mandibular advancement device : revision of the literature
Sleep apnea and hypopnea syndrome (SAHS) is a disorder characterized by intermittent and repetitive obstruction of the upper airway provoking pharyngeal collapse. It is characterized clinically by a triad of daytime hypersomnia, snoring and pauses in breathing during sleep that are normally reported by the partner. Polysomnography is the chosen method for diagnosing this pathology. Patients with this disorder tend to have the following dental and orofacial signs: a retrognathic jaw, a narrow palate, a wide neck, deviation of the nasal septum and relative macroglossia, among others. Dentists should be ready to evaluate the risk-benefit of certain dental treatment options for this public heal…
