This Concept Map, created with IHMC CmapTools, has information related to: TISSUE RETRACTION UPDATED, Rotary Gingival Curettage shows recession of clinical magnitude, forced on teeth for varying periods of time, Loe and Silness stated that Retraction cords, Chemomechanical method invloves use of cord, Monsel's solution (ferric subsulfate) Effective in Shrinking gingival tissue, 8% racemic epinephrine Have No difference in their effectivity, into a loop place Around the prepared tooth, cord which provides mechanical retraction, Alum Types 100% Alum solution, displacement of gingival tissue for temporary finish line exposure consists of methods such as Chemomechanical method, Zinc Chloride Causes More caustic irritating effect on tissues, Other Chemicals Include Cord impregnated with 8% zinc chloride plus 8:100 racemic epinephrine, 8% Zinc chloride May be used Satisfactory without permanent tissue damage, Tetrahydrozoline HCL More effective than Alum and epinephrine, cord that is impregnated with chemicals (drugs), mechanical retraction by pressure it creates on the free gingiva, Time retraction cord in the Sulcus, capillaries which is why bleeding cannot be controlled in some cases, Current of Modality such as dessication, moderately or highly damped current causing a zone of coagulation necrosis in the surface cells contacted by the tip
