The effect of external chemical disinfection and flushing the water lines of dental handpieces with water, on bacterial contamination of these handpieces, was investigated. External chemical wiping reduced the numbers of viable organisms present on the external surfaces of handpieces, but did not eliminate them completely. Micro-organisms were still present on the internal surfaces after flushing the handpieces with water for a period of five minutes. Sterilisation and/or disinfection of both the internal and external surfaces of handpieces are essential to minimise the risk of cross-infection from this source in the dental surgery.
研究了外部化学消毒以及用水冲洗牙科手机水管对这些手机细菌污染情况的影响。外部化学擦拭减少了手机外表面存在的活菌数量，但并未将其完全消除。用水冲洗手机五分钟后，内表面仍有微生物存在。对手机的内、外表面进行灭菌和/或消毒对于将牙科手术中此来源的交叉感染风险降至最低至关重要。
