USE OF OXYMETAZOLINE TO CONTROL BLEEDING IN SELECTED DENTAL PROCEDURES

牙龈内收是牙体修复的重要步骤。通常，由于龋齿、现有修复体、审美要求或需要额外的固位，嵌体、汞合金或冠的边缘在龈下延伸。大多数牙医使用肾上腺素浸渍索治疗牙龈移位和控制出血。肾上腺素的使用有潜在危险，在接受牙科手术的患者中必须谨慎使用。本研究的目的是评估羟美唑啉是否可以用于控制牙龈沟出血，以及在这种情况下对血压、脉搏率和心率的影响。

Gingival retraction is regarded as an important step in dental restorative procedures. Frequently, the margins of inlays, amalgams or crowns are extended subgingivally due to caries, existing restorations, esthetic demands, or the need for additional retention. The majority of dentists 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 are to evaluate oxymetazoline to determine if it can be used to control bleeding in the gingival sulcus and its effects on blood pressure, pulse rate and heart rate when used in this manner.
