Change of surface property of dental impression materials according to time and disinfection
Surface and Interface Analysis, 2008 The purpose of this study was to investigate the hydrophilicity of dental impression materials. Two ultrahydrophilic (Fusion, Genie) and four hydrophilic (Imprint II, Aquasilultra, Twinz, Perfect-F) impression materials were used.

Reactions to dental impression materials
Contact Dermatitis, 1977In the department of prosthetic dentistry at Groningen, during the past four years, approximately 2,000 persons have been treated with Scutan, an epimine plastic for temporary crowns and bridges and Impregum, a polyether impression material. A total of ten patients complained of untoward reactions. Patch tests with the basic materials were performed on

Dental Impression Materials: Reactor Response
Advances in Dental Research, 1988A review of the literature reveals an abundance of research papers which are focused on the physical properties and "simulated" clinical performance of impression materials. The three major developments during the past two decades were: (1) the introduction of the dimensionally stable addition silicones, (2) the development of dustless alginates, and ...

A rare allergy to a polyether dental impression material
Clinical Oral Investigations, 2011Polyether impression materials have been used in dentistry for more than 40 years. Allergic reactions to these materials such as reported in the 1970s ceased after replacement of a catalyst. Very recently, however, patients have started to report symptoms that suggest a new allergic reaction from polyether impression materials.

Tear and rupture of elastomeric dental impression materials
Biomaterials, 1984The curing time dependence of the tear energy, tensile strength and ultimate extension ratio of a range of characterized elastomeric impression materials was investigated. This variation of tensile strength and ultimate extension ratio was correlated with the development of the network structure.

Compatibility of alginate impression materials and dental stones
The Journal of Prosthetic Dentistry, 1971Abstract Four alginate (irreversible hydrocolloid) impression materials certified as meeting A.D.A. specification 18 for hydrocolloid impression materials were tested for compatibility with five dental stones (20 tests). Five samples of each alginate-stone combination were made and evaluated (100 casts).

Thiokol as a dental impression material
Acta Odontologica Scandinavica, 1957About two years ago a new type of elastic impression material, based on the synthetic rubber Thiokol, was placed on the market. The material is supplied in two tubes, the contents of which are mixed to a homogeneous paste before use. At or above room temperature the mix will quickly polymerize to form a rubbery mass.

The influence of dental gloves on the setting of impression materials
British Dental Journal, 1995The increased wearing of gloves during dental treatment has created new problems for general dental practitioners. One of these is the retarded set or total inhibition of addition silicones caused by natural latex gloves. This study was designed to test different gloves and impression materials in common use. Eight latex gloves, selected with different
