Water sorption and solubility of six proprietary composite resin materials were assessed, monomers eluted from the organic matrix during water storage identified. tests carried out with following times: 4 h, 24 h 7, 60 180 days. After storage, determined. Eluted analysed by high performance liquid chromatography (HPLC). Correlation between retention time registered peak reference was observed, UV‐spectra confirmed identity. The results showed an increase in until equilibrium for all one...
The purpose of the present study was to analyze relationship between fracture load monolithic zirconia crowns and axial/occlusal thickness evaluate resistance with reduced in comparison that lithium disilicate regular thickness.Monolithic (Lava Plus Zirconia, 3M/ESPE) specified thicknesses (IPS e.max press, Ivoclar/Vivadent) were fabricated using a dental CAD/CAM system press technique, respectively. cemented onto dies loaded until fracture. Based on measurements crown made by micro-CT load,...
Objectives The present study investigated the effect of cements on fracture resistance monolithic zirconia crowns in relation to their compressive strength.Materials and methods Four different were tested: zinc phosphate cement (ZPC), glass-ionomer (GIC), self-adhesive resin-based (SRC) (RC). RC was used both dual cure mode (RC-D) chemical (RC-C). First, strength each tested according a standard (ISO 9917-1:2004). Second, load-to-failure test performed analyze crown resistance....
To investigate how heat development in the pulp chamber and coronal surface of natural teeth with without cusps subjected to irradiance using light-emitting diode (LED)-light-curing units (LCUs) is associated (i) irradiance, (ii) time, (iii) distance, (iv) radiant exposure.Three different LED-LCUs were used. Their was measured a calibrated spectrometer (BlueLight Analytics Inc., Halifax, Canada). An experimental rig constructed control thermal environment teeth. The LED-LCU tip position...
Hand eczema and contact allergy in Swedish dentists were studied a multidisciplinary project. The aims of the study to establish diagnoses, investigate occurrence allergy, particular (meth)acrylates, evaluate certain consequences hand eczema. A postal questionnaire on skin symptoms, atopy occupational experience was mailed 3500 aged <65 years, licensed 1965–1995. response rate 88%. Among living 3 major cities, 14.9% ( n =191) reported during previous year. They invited clinical...
The purpose of this study was to elucidate the organic composition and eluates three resin-based pulp-capping materials in relation their indications safety data sheets. Uncured samples Theracal LC, Ultra-Blend Plus, Calcimol LC were investigated using gas chromatography-mass spectrometry (GC-MS) ultra-performance liquid (UPLC-MS). Identification/quantification 7-d leachables cured performed GC-MS for 2-hydroxyethyl methacrylate (HEMA), 2-(dimethylamino)ethyl (DMAEMA), camphorquinone (CQ),...
This study aimed to determine the crystalline phase composition of 3-6 mol% yttria-stabilized zirconia (3-6YSZ), specifically investigating presence tetragonal (t), cubic (c), and/or additional yttria-rich (t') phase.
The aim of this study was to investigate whether different fabrication processes, such as the computer-aided design/computer-aided manufacturing (CAD/CAM) system or manual build-up technique, affect fracture resistance composite resin-based crowns. Lava Ultimate (LU), Estenia C&B (EC&B), and lithium disilicate glass-ceramic IPS e.max press (EMP) were used. Four types molar crowns fabricated: CAD/CAM-generated (LU crowns); manually built-up monolayer (EC&B-monolayer layered (EC&B-layered EMP...
The aim of this work was to assess the influence bis-EMA content on degree conversion (DC) and its effect water sorption solubility.In a polytetrafluorethylene (PTFE) mould, 30 samples (Ø = 5 mm, height 2 mm) four experimental dental composite resins were cured for 10 s, 20 s 40 s. DC analysed by Fourier Transform (FT)-Raman spectroscopy. To analyse solubility, six 15 mm thickness 1 each (n 72) stored in at 37°C different storage periods: 24 h, 7 days days.When or increased with increasing...
Resin‐based composite molar crowns made by computer‐aided design/computer‐aided manufacturing ( CAD / CAM ) systems have been proposed as an inexpensive alternative to metal‐ceramic or all‐ceramic crowns. However, there is a lack of scientific information regarding fatigue resistance. This study aimed analyze the behavior resin‐based compared with lithium disilicate glass‐ceramic. One‐hundred and sixty bar‐shaped specimens were fabricated using blocks [Lava Ultimate LU ); 3M/ ESPE ]...
Background Haptics-enhanced virtual reality (VR-haptics), a supplementary tool for traditional oral health training, shows promise in enhancing knowledge acquisition, manual dexterity, performance, and student well-being. Aim The aim of this study was to understand dental educators' perceptions needs regarding the acceptability application VR-haptics education, as well gather suggestions system improvements. Methods In global cross-sectional study, VR-Haptic Thinkers Consortium used 28-item...

Eur J Oral Sci 2012; 120: 249–254. © 2012 The aim present investigation was to study influence yttria‐stabilized upon exposure an additional heat treatment, mimicking veneering process. green bodies discs prepared by cold isostatic pressing were sintered at 1,425, 1,500, or 1,575°C customize size. disc‐shaped specimens highly polished then...
Abstract An antimicrobial technique based on photo-oxidation of caffeic acid (CA) has recently been developed, but its effect biofilm-forming bacteria is unknown. The present study aimed to evaluate the photo-irradiated CA against Streptococcus mutans (cariogenic bacteria) biofilm as it relates hydroxyl radical formation. S . biofilms grown hydroxyapatite disks were immersed in solution (0–2 mg/mL) and irradiated with LED light at wavelengths 365, 385, 400 nm irradiances 500, 1000, 2000...
In the present study we investigated prevalence of self-reported hand eczema as well subjective associations between skin symptoms and composite/bonding or other dental materials among Swedish dentists. A questionnaire on symptoms, atopy, occupational experience, background factors was sent to a random sample (n=3,500) all dentists licensed since 1965. This group corresponds about half country's occupationally active The response rate 88%. had previously been validated against clinical...
Due to their inertness and unsurpassed aesthetic properties, ceramic materials are increasingly used as inlay materials. Based on a questionnaire, the frequency character of complications related therapy were assessed some important pitfalls clinical relevant factors discussed. A majority dentists performed between 1 10 inlays per month using several different As many 85% had observed in connection with inlays. Most reported was hypersensitivity transient nature (15%). The material revealed...
