Artificial G-load and chemical changes of saliva
Acta Astronautica, 1994Effectiveness of artificial G load is expected when it is used as a countermeasure against various bio-medical mishaps which are taking place in the micro-gravity environment, and probably more importantly, to prepare re-entry to the earth 1-G environment.

Wettability of 3 different artificial saliva substitutes on heat‐polymerized acrylic resin
The Journal of prosthetic dentistry (Print), 2019Statement of problem. The prosthodontic problems faced by a patient with xerostomia are of great concern. To aid in retention, artificial saliva substitutes should exhibit good wettability on the denture base. Purpose.

Lubrication of selected salivary molecules and artificial salivas
Dysphagia, 1989The lubrication regime displayed by human salivas (parotid and submandibular-sublingual), purified salivary molecules (the mucins MG1 and MG2 and alpha-amylases), and selected artificial salivas (Oracare D, Saliva Substitute, and Orthana) was assessed in vitro using a friction-testing device. Thin-film (boundary) lubrication was observed for all of the

Stress corrosion cracking of NiTi in artificial saliva
Dental Materials, 2007This paper aimed to study the mechanism of the cracking of orthodontic NiTi wire.Two orthodontic NiTi wires were subjected: (1) optical and scanning electron microscopy (SEM) to observe the fracture surface; (2) energy dispersive X-ray spectroscopy to determine the composition of the surface product; (3) anodic polarization to remove the surface ...

Leachability of denture-base acrylic resins in artificial saliva
Dental Materials, 1990We studied the influence of salivary acidity on leachability of denture-base acrylic resins with etiological interest in denture stomatitis because denture surfaces are frequently exposed to acidic conditions in the oral cavities. Auto-, heat-, and microwave-polymerized resins were immersed in artificial saliva with pH ranging from 4.0 to 6.8 at 37 ...

Corrosion of gold alloys and titanium in artificial saliva
European Journal of Oral Sciences, 1982Abstract – Two types of gold alloys and one type of pure titanium have been submitted to corrosion in artificial saliva for periods of up to about 2 months. The release of copper, gold or silver from the golod alloys as well as titanium from the titanium matrix was measured with nuclear tracer technique.

Dissolution of stainless steel in artificial saliva.
The International journal of oral & maxillofacial implants, 1997Dissolution of stainless steel type 304 in artificial saliva was studied by electrochemical methods, electron spectroscopy for chemical analysis, and atom absorption spectroscopy. The samples were polarized in the -400 mV (saturated calomel electrode) to -50 mV (saturated calomel electrode) range. The total thickness of the passive film was found to be
