As well as the introductory article 'Dialogical Skirmishes', Tan also interviewed Hans Ulrich Obrist
The Chemical Degradation of Denture Soft Lining Materials: A Study of The Interactions Between Denture Soft Lining Materials And Food Simulating Liquids
No full textPhDDenture soft lining materials are used as a cushion between the hard denture base and
the oral mucosa. Fluid sorption and solubility may contribute to material hardening,
roughening, cracking or tearing, loss of adhesion to the hard denture base or
contamination by extrinsic stains or yeasts. The ideal material is required to have low
fluid uptake, good wettability, retain compliance and surface integrity, and not support
fungal growth. Evaluation of behaviour in the oral environment is difficult and a
number of materials, such as artificial saliva and food simulating liquids, have been
recommended to simulate the environment. The two types of denture soft lining
materials commonly used in clinical practice are methacrylate and silicone based. These
together with an experimental elastomer were evaluated in this study.
Fluid sorption and solubility were determined by immersion of disc specimens in food
simulating fluids (distilled water, 3% acetic acid, 10% ethanol and 50% ethanol) and
artificial saliva at 37±1°C with weighing at set time intervals. Similar experiments were
carried out using liquids representing fatty food constituents with coconut oil and
1113307H. ardness was determined using a Shore A durometer. In order to determine
wettability, contact angle was measured using a computer microscope. The surface
roughness was assessed using a non-contact laser profilometer. Finally, an attempt was
made to identify leachable substances from the materials investigated using a Fourier
transform infrared spectrometer. An additional part of this study was to look at the
adhesion of one yeast species Candida albicans to commercial materials using various
protective coatings to determine their efficacy.
The resultsd emonstratedth at the type of liquid simulating foods or artificial saliva, and
immersion time significantly influenced the behaviour of the commercial denture soft
lining materials and the experimental elastomer during in vitro testing. The two groups
of materials behaviour were different. The two methacrylate-basedd enture soft lining
materials showed marked absorption and solubility which may be associated with the
loss of plasticisers. The two silicone-based denture soft lining materials showed much
less absorption and solubility under the same conditions. The experimental elastomer
showed marked swelling in oils, which was not expected, its chemical structure being
similar to a methacrylate. Shore A hardness remained unchanged during the fluid
immersion with the two silicone-based materials but showed measurable changes with
the two methacrylate-basemd aterials and the experimentale lastomer,I ncreaseds urface
roughness was also demonstrated with the two methacrylate-based materials, and
decreasedc ontact angle was found with the two silicone-basedm aterials. After various
surface treatment, coconut oil reduced Candida albicans adhesion in all cases

Free thinking - running
No full textWe've been running for two million years give or take. Shahidha Bari and Laurence Scott explore contemporary running as solitary inspiration and communal activity with the Geographer and 1999 Scottish Hill Running Champion, Hayden Lorimer, the artists Kai Syng Tan and Angus Farquhar, and the literary scholar and bare-foot artiste, Vybarr Cregan-Reid. Conversation ranges from feeling empowered on city streets to teaming up with the wind to the horrid history of the treadmill and explore whether Running deserves better representation in the arts. Guests: Vybarr Cregan-Reid - author of Footnotes How Running Makes Us Human Angus Farquhar, Creative Director of NVA Public Art, author of a blog 'The Grim Runner' Hayden Lorimer Running Geographer Kai Syng Tan, Artist and curator of a biennial festival Run Run Run Producer: Jacqueline Smith
