OF GINGIVAL RETRACTION AGENTS

In order to obtain an adequate impression of demarcation line area of a prepared tooth located in or below the gingival edge it is necessary to perform the dilatation and drying of the gingival sulcus using retraction cord impregnated with adequate retraction agents. The aim of the study was to carry out comparative analysis of advantages and disadvantages of commercially available gingival retraction agents. Commercial retraction agents include astringents (metal salts) and vasoconstrictors on the basis of epinephrine. Further research should be aimed at examining the possibility of using sympathomimetic vasoconstrictors (tetrahydrosolin and oxymetasolin) for gingival retraction.
