Gingival retraction or dilation is an important procedure in the fabrication of fixed prostheses. Quite often, the margins of these restorations are placed very close to the gingival margin, or even subgingivally, for aesthetic and functional reasons. Therefore, the operating surgeon must correctly record the prepared cervical finish line to enable adequate marginal integrity for the restoratio...
متن کاملDynamic Oxidoreductive Potential of Astringent Retraction Agents ( gingival margin retraction agents / cytotoxicity / human gingival fibroblasts )
The aim of this study was to evaluate the dynamics of the cytotoxicity of gingival margin retraction astringents based on aluminium chloride, aluminium sulphate, and ferric sulphate (solutions and gels) in human fibroblasts isolated from gingiva. The cytocompatibility of ten astringent-based chemical retraction agents: Gingiva Liquid, Alustin, Racestypine, Orbat sensitive, Astringedent®, Alusta...
متن کاملCytotoxic Potential of Vasoconstrictor Experimental Gingival Retraction Agents - in Vitro Study on Primary Human Gingival Fibroblasts (gingival margin retraction agents / cytotoxicity / human gingival fibroblasts)
The aim of this in vitro study was to evaluate the cytotoxic effects of the vasoconstrictor experimental gingival retraction agents (VEGRAs) in a dynamic setting. The strong cytotoxic effects of the astringent-based conventional gingival retraction agents (ACGRAs) on human gingival fibroblasts (HGFs) in vitro was our motivation to evaluate the biocompatibility of the vasoconstrictor-based exper...
متن کاملThe rabbit gingival tissue response to retraction liquids and tetrahydrozoline.
UNLABELLED BACKROUND/AIM: Retraction agents for temporary vertical and lateral suppression of gingival tissue as well as bleeding control and fluid flow in the gingival sulcus are expected to have maximal efficiency without irreversible damage of local tissue and adverse systemic effects. The research started from the assumption that tetrahydrozoline is a biologically more acceptable means of g...
متن کاملGingival Retraction - Techniques and Materials: a Review
Though the necessity to place the finish line into the gingival sulcus obviously has a negative effect on the quality of the impression,4,8-10 aspects of gingival retraction have only been sparsely investigated.3-5 The aim of gingival retraction is to allow access for the impression material beyond the abutment margins and to create space for the impression material to be sufficiently thick. Te...
