“…An adhesive‐painted hard acrylic cover sheet (Triad VLC; Dentsply, York, PA) was placed on top of the mold to keep a uniform 3‐mm thickness of impression material. Latex gloves were avoided to rule out latex's detrimental effect on polymerization of impression materials . The setting time was predetermined to be, as per the manufacturer's instruction, multiplied by 1.5 to compensate for the intraoral environment temperature and to ensure adequate time for polymerization before the impression material was evaluated …”

“…Therefore, one requirement of impression materials is the biocompatibility of these materials with oral fluids and other dental materials; however, this requirement is not always satisfied. For example, inhibition of polymerization has been reported in relation to rubber dam material, cements, gingival displacement cords and medicaments, dentin bonding agents, flowable composite resins, and latex gloves …”

“…However, it shows some disadvantages as polymerization is inhibited by the use of latex gloves during its handling. [3033] Thus, the polyvinyl siloxane used for the matrix impression was handled without latex gloves and the same impression was used for several dies.…”

Aim:This work evaluated the mechanical and surface behavior of different die materials. The studied materials are polyurethane resin Exakto-Form (Bredent), Gypsum type IV, Fuji Rock EP (Gc), and Durone (Dentsply).Materials and Methods:Two metallic matrices molded in polyvinyl siloxane provided 30 cylindrical test specimens for the diametral compression test and 30 hemispherical test specimens for the surface rugosity test. The cylindrical test specimens were submitted to tests of diametral compression strength using a DL2000 universal assay machine, with a load cell of 2000 Kgf and constant speed of 1 mm/min connected to the software. Kruskal–Wallis and Dunn's nonparametric tests were used to analyze the results. The hemispheres were submitted to the surface rugosity assay using a SJ201-P rugosimeter with a sensitivity of 300 μm, speed of 0.5 mm/s, and cut-off of 0.8 mm, and the readings were taken on the convex surface of the test specimens and metallic matrix. Results were analyzed using with Fisher's least significant differences test (LSD) and Dunnett's test.Results:Kruskal–Wallis test showed significant difference between die materials for diametral compression strength (P = 0.002). Dunn's test showed significantly higher values for modified polyurethane resin (Exakto-Form). The gypsum type IV, which did not significantly differ regarding diametral compression strength, showed 34.0% (Durone) and 42.7% (Fuji Rock) lower values in comparison to Exakto-Form.Conclusion:Within the parameters adopted in this study, it is possible to conclude that Exakto-Form polyurethane resin showed higher resistance to compression and was closer to the metallic matrix rugosity, and, along with the gypsum type IV Durone, showed better reproducibility of details relative to the Fuji Rock.

“…The direct or indirect contact with latex gloves or rubber dams seems to increase the risk of polyvinylsiloxane polymerization inhibition 5,6,9,13,16,18-20,22,25-27 , which is an important problem because latex gloves are some of the protective gear most often worn by dental professionals 10 .…”

ObjectivesThis study investigated the possible interactions between three addition silicone materials (Express®, Aquasil Ultra® and Adsil®), three hemostatic agents (ferric sulfate, StatGel FS®; aluminum sulfate, GelCord®; and aluminum chloride, Hemostop®) and gingival retraction cords previously handled with latex gloves to determine whether direct contact with medicaments or indirect contamination by latex in conditions similar to those found in clinical practice inhibit or affect the setting of the impression materials. Material and MethodsA portable device for the simultaneous test of several specimens was specifically developed for this study. Polymerization inhibition was analyzed by examination of the impressions and the molded surface. Ten trials were performed for each addition silicone material used in the study, at a total of 240 study samples. ResultsAll the samples tested (N=240) were nonreactive regardless of the type of combination used. ConclusionsAluminum sulfate, ferric sulfate and aluminum chloride hemostatic solutions did not show any inhibitory potential on the addition silicone samples under study, and there were no changes in polymerization as a result of contact between addition silicone and retraction cords handled with latex gloves.
