Abstract

This study examined pulpal blood flow and oxygen consumption by the dental pulps of dogs. Blood flow was measured by the radioactive microsphere method and oxygen uptake was determined by the indirect Warburg approach. These variables were assessed 2 days after the canine teeth had been exposed and treated with either a cotton pellet impregnated with 1 per cent prednisolone or normal saline. The analysis indicated that the pulpal blood flow as well as the oxygen consumption did not differ between the steriod-treated tooth and the corresponding saline-treated tooth in the same jaw.

摘要

本研究检测了犬牙髓的血流量和氧消耗量。采用放射性微球法测量血流量，通过间接瓦氏法测定氧摄取量。在犬齿暴露并用含1%泼尼松龙的棉球或生理盐水处理2天后，对这些变量进行评估。分析表明，在同一颌骨中，用类固醇处理的牙齿和相应的用生理盐水处理的牙齿之间，牙髓血流量和氧消耗量没有差异。
