USE OF OXYMETAZOLINE TO CONTROL BLEEDING IN SELECTED DENTAL PROCEDURES

牙龈退缩被认为是牙科治疗的重要步骤 恢复性准备。 通常，嵌体、汞合金的边缘 或牙冠由于龋齿而向龈下延伸， 修复、美学要求以及额外固位的需要。 大多数牙科医生使用肾上腺素浸渍线进行牙龈 移位和控制出血。 肾上腺素的使用 具有潜在危险，必须谨慎用于患者 正在接受牙科手术 本研究的目的是 评估几种长效肾上腺素能药物，以确定它们是否可以 用于控制龈沟出血， 血压、脉搏和心率。

Gingival retraction is regarded as an important step in dental restorative preparations. Frequently, the margins of inlays, amalgams or crowns are extended subgingivally because of caries, existing restoration, esthetic demands, and the need for additional retention. The majority of dentist use epinephrine-impregnated cords for gingival displacement and to control bleeding. The use of epinephrine is potentially hazardous and must be used with caution in patients undergoing dental procedures. The objectives of this study is to evaluate several long acting adrenergic agents to determine if they can be used to control bleeding in the gingival sulci and their effects on blood pressure, pulse rate and heart rate when used in this manner.
