BACKGROUND/AIM Dimensional stability and accuracy of an impression after chemical disinfection by immersion in disinfectants are crucial for the accuracy of final prosthetic restorations. The aim of this study was to assess the deformation of addition and condensation silicone impressions after disinfection in antimicrobial solutions. METHODS A total of 120 impressions were made on the model ...

Soft denture-lining materials are an important treatment option for patients who have chronic soreness associated with dental prostheses. Three distinctly different types of materials are generally used. These are plasticized polymers or copolymers, silicones, or polyphosphazene fluoroelastomer. The acceptance of these materials by patients and dentists is variable. The objective of this study ...

keloids are aesthetically disfiguring and severely disabling. the optimal treatment remains undefined. this clinical study, evaluate the efficacy and side effects of combined topical silicone and 5-fluorouracil on the prevention of keloids. in this double blind randomized clinical trial, fifty patients with keloids were randomly allocated in two groups. the control group were treated by periles...

that every single material derived from silicon chemistry seems extremely modern. Silicon occurs naturally in sand and rocks, generally in the form of silica and silicate, and is the second most abundant element on earth after oxygen. Only crystalline silicon and the silanes and organosiloxanes are truly modern products: they do not occur freely in nature, but are entirely the product of human ...

Despite the worldwide use of silicones in scar management, its exact working mechanism based on a balanced occlusion and hydration, is still not completely elucidated. Moreover, it seems peculiar that silicones with completely different occlusive and hydrating properties still could provide a similar therapeutic effect. The objective of the first part of this study was to compare the occlusive ...
