Hybrid nanoparticles (CuChNP) comprising of copper with a chitosan shell were synthesized. Antimicrobial properties CuChNP assessed against Streptococcus mutans (S. mutans), one the main bacterium that causes tooth decay. Antibacterial activity S. was comparable to oral antimicrobial agents, such as chlorhexidine, and cetylpyridinium chloride. Particularly, exhibited superior capacity prevent growth on human surface well disrupt kill bacterial cells in an established dental biofilm. Chitosan...
Objective To prepare nanocomposite cements based on the incorporation of bioactive glass nanoparticles (nBGs) into BiodentineTM (BD, Septodent, Saint-Maur-des-Fosses Cedex, France) and to assess their properties. Material Methods nBGs were synthesised by sol-gel method. BD nanocomposites (nBG/BD) prepared with 1 2% weight; unmodified GC Fuji IX (GIC, Corporation, Tokyo, Japan) used as references. The in vitro ability materials induce apatite formation was assessed SBF X-ray diffraction...
Leptospirosis is an important zoonosis with worldwide distribution caused by pathogenic bacteria of the genus Leptospira. The North American mink (Neovison vison) has role in environmental contamination Leptospira, as minks live aquatic environments and are predators rodents. Blood kidney samples were obtained from 57 Southern Chile 39° S to 45° S. Pathogenic species Leptospira detected PCR on 31/57 minks. To determine species, we sequenced 16S ribosomal RNA (rRNA) gene nine positive...
Calcium silicate cements have been used as dental materials for more than twenty years; however, their use in restorative dentistry is recent. Better mechanical properties and shorter curing times make them suitable a variety of applications which they are substitute dentin, including direct/indirect pulp capping cavity base/liner. These may also be to restore enamel temporarily. This article seeks review the available scientific evidence with focus on dentistry. The information was gathered...
To assess the effects of application an oxalic acid-based desensitizing agent before restoration noncarious cervical lesions (NCCLs) with either a silorane-based or methacrylate-based composite resin on decreasing absolute risk and intensity dentin hypersensitivity over course 1-year follow-up.NCCLs in 31 patients (age range 24-66 years) were selected randomly divided into four groups (n = all groups). In Z250 P90 groups, restorations performed (Filtek Z250) (Silorane P90), respectively. +...
The aim of the study was to evaluate chemical composition and radiopacity new calcium-silicatebased cements. Discs 10 mm x 1 ± 0.1mm were prepared BiodentineTM, TheraCal, Dycal GC Fuji IX (n=5). samples radiographed directly on an PSP occlusal plate adjacent aluminium step wedge. each specimen determined according ISO 9917/2007. Statistical analyses carried out using ANOVA Tukey's test at a significance level 5 %. constitution materials by scanning electron microscopy (SEM) energy dispersive...
Abstract Cerebral palsy (CP) is a condition caused by brain damage before, during, or shortly after birth. Communication can be challenge when treating patients with CP. Some communicate verbally, while others use augmentative alternative communication tools have individualized means of communication. Therefore, professional dental treatment in individuals CP challenging, especially if the patient affected trauma and requires emergency treatment. This report shows how skills assessment...
This study aimed to investigate the cytotoxicity and bioactivity of a novel nanocomposite containing nanoparticles bioactive glass (nBGs) on human dental pulp stem cells (hDPSCs). nBGs were synthesized by sol–gel method. Biodentine (BD) nanocomposites (nBG/BD) prepared with 2 5% wt nBG content; unmodified BD ionomer cement used as references. Cell viability attachment evaluated after 3, 7 14 days. Odontogenic differentiation was assessed alkaline phosphatase (ALP) activity days exposure....
Background: Confinement due to the COVID-19 pandemic has made dental treatments impossible in Chile and many other countries, including diabetic patients with periodontitis. The aim of present study was evaluate impact periodontal therapy terms oral health-related quality life (OHRQoL) during a cohort Material Methods: Thirty-eight stage III-IV periodontitis, enrolled for therapy, were screened. Periodontal clinical parameters attachment loss (CAL), probing pocket depth (PPD) bleeding on...
The aim of this study was to carry out a retrospective cases seen at the Child and Adult Dental Traumatology Clinic, Faculty Dentistry, Universidad de Chile, Santiago. A carried analysing records patients Chile from January 2012 March 2017. inclusion criteria that patient complaint due dental trauma. Data were tabulated indicating age sex patient, cause, day, tooth involved initial diagnosis Chi-square, Shapiro Wilk normality test Mann-Whitney used for frequency analyses. total 117 analysed,...
Objetivo: Sintetizar los resultados sobre estudios epidemiológicos de caries dental, enfermedad periodontal, desdentamiento y lesiones mucosa oral base poblacional con representatividad nacional regional en adultos chilenos (≥15 años).
El objetivo de este estudio fue determinar las consecuencias clínicas expresadas en índices COPD y ceod su relación con la presencia hipomineralización incisivo molar (HIM) una población escolares 6 a 12 años provincia Santiago. Este corte transversal realizado 851 Santiago, quienes fueron evaluados por 2 dentistas calibrados. Con consentimiento los tutores legales, examinados, se utilizaron criterios diagnósticos para HIM Academia Europea Odontopediatría (EAPD). La historia caries...

The purpose of this study was to investigate the accuracy and interobserver reliability examiners with different levels clinical experience, when diagnosing radiographic proximal caries lesions. Bitewing radiographs were selected from a patient attending Operative Dentistry Clinic, Universidad de Chile. Radiographic examination performed by three groups: A: third year dentistry students, B: fourth C: dentist recently graduated. Thirty-two surfaces scored as: 0, sound; 1: enamel caries; 2:...
Introducción A partir de Octubre del 2019 y hasta el 2020, muchas personas fueron víctimas violencia por parte agentes estado, las que sufrieron tanto trauma ocular (TO) como dentomaxilar (TDM). Dicha situación, generó un psicológico importante no solo remece al propio individuo, sino también a su entorno más inmediato, sea familia, amistades o compañeros trabajo/estudios, lo permite ver una irradiación social vivenciado Objetivos Describir impacto en percibido afectadas TO TDM ejercida...
