作者将国产CJY—1 型超声洁牙器稍加改制,用于根管预备,选用离体上颌前牙8只,分别用生理盐水、3％双氧水、5.25％次氯酸次钠液和5.25％氯酸钠及17％EDTA液冲洗后,一组经超声处理,一组未经超声处理,然后用电镜观察.结果发现国产CJY型超声洁牙器经探头改制后可有效地用于根管超声预备;使用5.25％次氯酸钠液作冲洗液效果最好,若与17％EDTA协同使用效果尤佳.
The author modified the domestic CJY-1 ultrasonic scaler slightly for root canal preparation. Eight anterior maxillary teeth were selected and treated with normal saline, 3% hydrogen peroxide solution, 5.25% sodium hypochlorite solution and 5.25% After sodium hypochlorite and 17% EDTA solution were rinsed, one group was sonicated, one group was not sonicated and then observed by electron microscope.The results showed that domestic CJY ultrasonic scaler could be effectively used for root canal ultrasound Preparation; use of 5.25% sodium hypochlorite solution as the best solution, if used in combination with 17% EDTA is particularly effective.
