The aim of this study was to compare the clinical performance root caries restorations after a six-month period using two methods, conventional technique with rotary instruments and an atraumatic restorative (ART), in institutionalized elderly population city Bogotá, Colombia. Root represents multifactorial, progressive, chronic lesion softened, irregular darkened tissue involving radicular surface; it is highly prevalent elderly, especially those who are physically or cognitively impaired....
The use of light sources during the application bleaching can reduce time and improve results, but at same this increase dental temperature. objective study was to evaluate performance two agents in temperature with emitted by diodes (LED)-unit.Forty third molars were obtained randomized: whiteness without lamp (WHN) Pola office (PON) groups, systems based on 35% hydrogen peroxide used, according manufacturer specifications. For (WHL) (POL) groups boosted. A spectrophotometer ∆WID equation...
Universal adhesives provide the possibility of simplified protocols for using ceramics; however, determining synergy these with silanes and replacing requires extensive research.To evaluate influence a universal adhesive, associated airborne-particle abrasion, acid etching, silane, on bond strength feldspathic ceramic CAD-CAM to composite resin.CAD-CAM blocks were cut into 2-mm slices randomly divided six groups (n = 10): A1, Single Bond (SBU); A2, Adper 2 (SB2); B1, silane + SBU; B2, SB2;...
A reliable adhesion between fixed devices and dental surfaces is a key factor for the clinical success of any orthodontic treatment. Adhesion preparation associated with damages related to abrasive cleaning, enamel structure defacing caused by etching, loss when removing resin remnants at treatment finishing stage or conditioning surface adhesive failure fractures bracket removal. The objective this study was compare shear bond strength metallic brackets adhered novel non-damaging...
The health emergency declaration owing to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has drawn attention toward nosocomial transmission. transmission of the disease varies depending on environmental conditions. Saliva is a recognized SARS-CoV-2 reservoir in infected individuals. Therefore, exposure fluids during dental procedures leads high risk contagion. This study aimed develop an infection prediction model for COVID-19 based analysis settlement aerosolized particles...
<ns3:p><ns3:bold>Background:</ns3:bold> Polymer infiltrated ceramic networks, or hybrid ceramics, are a combination of infiltrating polymerizable organic monomers into pre-sintered porous matrix. In addition to having good mechanical properties, the polymer network must comply with possibility adequate bonding resinous cement. The surface conditioning this material be carefully considered due its composition and network. purpose research is evaluate effect hydrofluoric acid self-etching...
Introducción: No existe un protocolo defi nitivo para la reparación de cerómeros. Los adhesivos universales debido a su composición e indicaciones pueden ser una alternativa dentro restauraciones poliméricas, pero asociación los silanos con requiere más investigación. Objetivo: Evaluar y comparar resistencia unión dos en interfase cerómero-resina, asociado o no agente silano. Material métodos: Se realizaron seis bloques cerómero se trataron según las siguientes variables: (A) sin...
Introducción y objetivo: las resinas acrílicas son los materiales idóneos para la elaboración prótesis totales, sin embargo, caídas o golpes hace susceptibles de fracturas. Conocer propiedades limitaciones acrílicos en nuestro entorno, nos permite realizar tratamientos con mejores materiales. El objetivo este estudio fue comparar resistencia al impacto dos convencionales alto bases protésicas. Materiales métodos: se realizaron 40 barras cera base ser enmufladas acuerdo especificaciones...
Abstract ObjectivesThis study aimed to develop a risk prediction scale for COVID-19, based on an analysis of the dynamic behavior aerosols generated during dental procedures.Materials and methodsThe dispersion procedures performed in six clinics was evaluated using standardized photographs. The digital images were processed analyze stained area dimensions drops. A logistic regression model built with following variables: ventilation, distance from mouth, instrument used, mouth be treated,...
