Gingival retracting cords including propylhexedrine (e.g., propylhexedrine HCI) for providing hemostasis and retraction or displacement of gingival tissue. The retraction cords include a hemostatic and tissue stiffening and retraction effective amount of propylhexedrine which avoids the negative side effects associated with the use of epinephrine, commonly used in conventional retraction cords. Retraction cords incorporating propylhexedrine do not cause increased blood pressure or accelerated heart rate. In addition, such retraction cords may include astringents, such as iron (III) salts without causing discoloration of the retraction cord, the patient's teeth or gums, or the fingers of the dental practitioner, as would occur if one were to blend epinephrine with iron (III) salts. Water or other appropriate solvents may be used to impregnate, or otherwise treat, the retraction cord with propylhexedrine (e.g., propylhexedrine HCI).
牙龈牵引绳包括丙基羟地林(如丙基羟地林 HCI),用于止血和牵引或移位牙龈组织。牵引绳包括止血、组织增硬和牵引有效量的丙基己肾上腺素,避免了传统牵引绳中常用的肾上腺素的负面影响。含有丙氧肾上腺素的牵引绳不会导致血压升高或心率加快。此外,这种牵引带还可包括收敛剂,如铁(III)盐,而不会导致牵引带、患者的牙齿或牙龈或牙科医生的手指变色,如果将肾上腺素与铁(III)盐混合使用就会出现这种情况。可以使用水或其他适当的溶剂来浸渍或以其他方式用丙氧肾上腺素(如丙氧肾上腺素 HCI)处理牵引带。
