不同方法清洗牙周科刮治器的效果比较

Efficiency of Cleaning Curets by Different Methods and Their Comparison

目的比较不同方法清洗牙周科刮治器的效果。方法按照随机原则,将临床使用后的刮治器分为4组,A组:碱性清洁剂(预泡液)+酶清洗剂+超声;B组:刷洗+酶清洗剂+超声;C组:酶清洗剂+超声;D组:预泡液+酶清洗剂+刷洗。结果A组(82.3%)、B组(86.5%)和D组(83.7%)的清洗效率明显高于C组(75.9%),差异有统计学意义(P<0.01)。结论预泡液+酶清洗剂+超声的清洗方法更适合于结构复杂、缝隙沟槽多且污染严重的器械,同时又能减少刷洗过程给护士带来的风险,是一种高效、安全而且省力的方法,可广泛的应用于临床。

OBJECTIVE To compare the efficiency of cleaning curets by different methods. METHODS After clinical use, curets were randomly divided into 4 groups according to the different cleaning methods： groups A, immersing ＋ enzyme＋ ultrasonic ; B, brushing ＋ enzyme ＋ ultrasonic; C, enzyme ＋ ultrasonic; D, immersing ＋ enzyme ＋ brushing. RESULTS The efficiency of cleaning curets was significantly higher in groups A（82.3%）, B（86.5 %） and D（83.7%） compared with group C（75. 9%, P〈0. 01）. CONCLUSIONS Among the cleaning methods the immersing＋ enzyme＋ ultrasonic is more suitable for cleaning instruments with complex structure, more fissures and pits, and serious pollution. Meanwhile, this method can reduce the risk during brushing for nurses. It is an efficient, safe and laborsaving method, which can be extensively applied in clinic.
