Contact Dermatitis, EarlyView.We report three cases of allergic contact dermatitis (ACD) caused by acrylic resins used in creative hobbies, rather than by epoxy resins, despite these products being incorrectly labelled as “epoxy UV” resins. ABSTRACT Background Several cases of contact allergy to epoxy resins used in creative hobbies have been reported in recent years but not to ...

Contact 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

Flexo‐printable glucomannan‐based biofilm
Coloration Technology, EarlyView.Abstract Biofilms were synthesised from glucomannan and xylan. The ratio of glucomannan: xylan varied from 90:10 (g/g) to 70:30 (g/g). Nanofibrillated cellulose was added to enhance the mechanical properties of the biofilms. In another approach, glucomannan/xylan suspensions were crosslinked with tartaric acid (TA) or citric acid (CA).

Dental Traumatology, EarlyView.ABSTRACT Background/Objectives The use of mouthguards protects teeth and the supporting tissues against impacts. Digital impressions and 3D‐printed models can reduce manufacturing steps and minimize discomfort. This study evaluated the fit, comfort, and usability of custom‐made mouthguards, obtained by conventional and digital workflow, in amateur ...

Tactile Perception of 3D‐Printed Typodont Materials in Dental Education: A Systematic Review
European Journal of Dental Education, EarlyView.ABSTRACT Background Adoption of additive manufacture of printed typodonts within dentistry for education occurs despite inadequate reproduction of desirable tactile characteristics of human tooth tissues. Variable findings regarding material properties and educational outcomes of 3D‐printed typodonts are reported.

European Journal of Oral Sciences, EarlyView.Abstract This study evaluated the effect of the number of simulated endodontic treatment visits and the type of irrigant on the surface roughness, microhardness, topography, and fracture resistance of root dentin. Bovine roots were distributed into six groups (n = 14) according to the irrigant and number of treatment visits: 0.9% saline solution ...

European Journal of Oral Sciences, EarlyView.Abstract This study determined the influence of post‐curing protocols on the color stability of provisional and long‐term 3D‐printable resin composites. Disc‐shaped specimens were fabricated from a provisional (Prov) and long‐term (Crown) 3D‐printable resin composites using a digital light processing printer.
