title: Fluid absorbency of retraction cords after soaking in aluminum chloride solution.
abstract: Soaking retraction cord in an aluminum chloride solution before placing into gingival sulci does not lessen the cord's ability to absorb fluid. Black silk suture is clinically ineffective and should be replaced with a dark, size 0 impregnated retraction cord.
