Synergistic Effect of Adsorption and Enzymatic Conversion in the Bisphenol-A Removal by Laccase Immobilized on Poly(glycidyl methacrylate-co-ethyleneglycol dimethacrylate)

open access: yesJournal of the Brazilian Chemical Society, 2017
Carriers with different functional groups (epoxy, aldehyde, ethyldiazonium, phenyldiazonium and amino) were tested for immobilization of T. versicolor laccase on GMA-co-EGDMA (glycidyl methacrylate-co-ethyleneglycol dimethacrylate) microspheres. Laccase immobilized on GMA-co-EGDMA containing the phenyldiazonium functional group showed the highest ...

Assessment of knowledge, attitude, and practice of faculty and postgraduates toward Bisphenol A (BPA) exposure in dental care

open access: yesJournal of the Pakistan Medical Association
Bisphenol A (BPA) is commonly used in resin-based dental materials and is categorised as an endocrine-disrupting compound. This study aimed to evaluate the knowledge, attitudes, and practice toward the use of BPA among faculty members and postgraduate ...

Occupational Contact Allergy to Components of Epoxy Resin Systems: Descriptive and Comparative Epidemiological Analyses Based on IVDK Data 2008–2022

open access: yesContact Dermatitis, EarlyView.
This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...

SHEAR BOND STRENGTH OF BISPHENOL A-GLYCIDYL METHACRYLATE ADHESIVE RESIN AFTER APPLICATION OF EUCALYPTUS OIL BEFORE DEBONDING METALLIC ORTHODONTIC BRACKET

open access: yesInternational Journal of Applied Pharmaceutics, 2019
Objective: Debonding of orthodontic braces could lead to enamel fracture and moderate discomfort for the patients. This study was conducted toexamine whether eucalyptus oil and eucalyptol were effective in decreasing the shear bond strength and facilitate the debonding of metallic bracketsbonded with bisphenol A-glycidyl methacrylate (bis-GMA) adhesive

Tetrahydrofurfuryl Methacrylate and Isobornyl Acrylate: Possible New Sensitisers in Hearing Aid Ear Moulds

open access: yesContact Dermatitis, EarlyView.
A case series of eight patients with allergic otitis externa from contact allergy to hearing aid ear moulds is presented. All were patch test positive to tetrahydrofurfuryl methacrylate and three to isobornyl acrylate. It is postulated that these are likely relevant allergens present in such devices. ABSTRACT Background Allergic contact dermatitis from

Fracture load and three‐dimensional internal void analysis of direct composites used to restore worn molars

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Role of adjunctive methacryloyloxydecyl dihydrogen phosphate primers on dentin bond strength of universal adhesives under saliva and artificial aging

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study evaluated whether adjunctive 10‐methacryloyloxydecyl dihydrogen phosphate (MDP) primers enhance the microtensile bond strength (µTBS) of two universal adhesives (UAs) to dentin under artificial aging and repeated salivary contamination applied at each bonding step.

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.
