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、银汞合金的边缘 或牙冠因龋齿而伸向龈下，存在 修复、审美需求和额外保留的需要。 大多数牙医使用肾上腺素浸渍的牙线进行牙龈治疗。 移位和控制出血。肾上腺素的使用是 有潜在危险，必须谨慎用于患者 正在接受牙科手术。这项研究的目的是 评估几种长效肾上腺素能药物，以确定它们是否可以 用于控制牙周沟出血及其对患者的影响 当以这种方式使用时，血压、脉率和心率。

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.
