This study quantitatively evaluated the fluorescence intensity of resin composites with different opacities and translucencies determined changes in after accelerated aging, using human enamel dentin as controls. Six microhybrid nanofilled composites, each three shades, were tested. Ten sound incisors used to obtain specimens separately. Fluorescence measurements obtained a spectrophotometer before (baseline) aging at 150 kJ energy for 120 hours. One-way analysis variance (ANOVA)...
The aim of this study was to establish the reaction kinetics 35% hydrogen peroxide and sodium ascorbate determine mass antioxidant required neutralize bleaching gel.The method used quantify based on United States Pharmacopeia (1995)(26). Oxidation-reduction titration confirm concentration between them.The results indicated a direct correlation that agent. In addition, 5 min contact sufficient used.This in vitro showed amount for reduction is directly related latter. oxidant longer...
The objective of this study was to determine the degree conversion (DC), hardness (H), and modulus elasticity (E) a dual-cured resin cement, light-cured flowable cured through opaque or translucent ceramic with different exposure times. RelyX ARC (dual), Veneer (light-cured), Filtek Z350 Flow specimens 0.5 mm thick were for 40, 80, 120 seconds 1-mm feldspathic disks (n=10). stored at 37°C 24 hours. Half each specimen used test DC other half H E. determined in Fourier transform infrared...
The semi-direct restorative technique using composite resin has gained increased popularity in clinical practice due to several advantages: reduced cost for patients, the feasibility of restorations teeth with significant structural loss, time[1]saving, improved margin adaptation, polishing, polymerization, and aesthetics restoration performed outside mouth. Objective: aim this study was present a case involving posterior substantial coronal destruction technique. Case report: tooth prepared...
The present study evaluated the effect of training on dental students' ability for matching two different shade guides.The was conducted in 2012. participants were 88 male and female undergraduate students from Brazil Portugal, with or without previous color education vision refractive errors (response rate 73.33%). They asked to match a pair set guides Vita Classical (VC) Vitapan 3D Master (3DM), 20-minutes' rest between each match. sets assembled over neutral gray background under...
Abstract The aim of this study was to evaluate the effects irradiance, light emission wavelength, and heating different curing units on Knoop Vickers hardness a hybrid composite resin. specimens were irradiated during 40 s with ten units, LEDs, halogen lights. spectral each unit assessed by spectrometer, irradiance measured two commercial radiometers, thermocouple. After 48 h storage in dark recipient under 100% humidity condition, tests carried out. results analyzed ANOVA, Tukey HSD test (...
The aim of the study was to evaluate dentinal tubule occlusion, measuring dentin permeability (Lp) and using different desensitizing agents before after abrasive/erosive challenge. Dentin discs from 42 healthy human third molars were obtained. Minimum Lp measured a smear layer simulation #600 SiC paper maximum an immersion in 0.5 M EDTA. specimens treated with desensitizers: two varnishes (Clinpro XT Varnish-CV, Fluor Protector-FP), paste (Desensibilize Nano P-NP) gel (Oxa Gel-OG). each...
The aim of this study was to evaluate in vitro the hardness and shrinkage a pre-cooled or preheated hybrid composite resin cured by quartz-tungsten-halogen light (QTH) light-emitting diode (LED) curing units. temperature on tip devices also investigated. Specimens Charisma were produced with metal mold kept under 37°C. syringes submitted 4°C, 23°C, 60°C (n=20) before light-curing, which carried out Optilux 501 VCL Elipar FreeLight 2 units for 20 seconds. specimens 37°C high humidity...
Abstract The objective is to present a clinical case of dental autotransplantation managed with surgery, orthodontics, endodontics, periodontics, and aesthetic rehabilitation. A 10-year-old boy sought treatment after avulsion the maxillary left central incisor, which was not reimplanted. Based on anamnesis, examination, complementary examinations, agenesis mandibular second premolars except right premolar observed. After multidisciplinary planning, space in incisor region opened receive...
