Aerosol has been considered one of the main concerns in the dental community because of possible risk of infection transmission. Antiseptics used in the form of pre-procedural rinses can reduce aerosol contamination during dental procedures. The aim of this study is to evaluate and compare the efficacy of 0.05% cetylpyridinium chloride and 0.2% chlorhexidine pre-procedural rinses at 47ºC and 18ºC in reducing aerosol contamination during ultrasonic scaling procedures. Forty subjects were divided randomly and equally into four groups: A1 and A2 to receive cetylpyridinium chloride and B1 and B2 to receive chlorhexidine as pre-procedural rinses. Aerosol produced during the ultrasonic scaling procedure was collected on blood agar plates at three different locations, which were incubated at 37ºC for 48 hours and analysed for bacterial colony forming units (CFU). Cetylpyridinium chloride (0.05%) as a pre-procedural rinse was found to be equally effective in reducing aerosol contamination when compared with 0.2% chlorhexidine rinse (p > 0.05). Also, greater reduction of CFU was found with the use of tempered rinses at 47ºC with a highly statistically significant difference (p < 0.001). Cetylpyridinium chloride (0.05%) can be considered as a promising alternative to the gold standard 0.2% chlorhexidine, with tempering the rinse showing the definite edge.
由于存在感染传播的潜在风险，气溶胶一直是牙科领域主要关注的问题之一。术前含漱形式使用的防腐剂可减少牙科手术过程中的气溶胶污染。本研究的目的是评估和比较47℃和18℃下0.05%西吡氯铵和0.2%氯己定术前含漱在超声洁治过程中减少气溶胶污染的效果。40名受试者被随机且平均分为四组：A1组和A2组接受西吡氯铵，B1组和B2组接受氯己定作为术前含漱。超声洁治过程中产生的气溶胶在三个不同位置收集到血琼脂平板上，在37℃孵育48小时并分析细菌菌落形成单位（CFU）。与0.2%氯己定含漱相比，0.05%西吡氯铵作为术前含漱在减少气溶胶污染方面同样有效（p>0.05）。此外，47℃温热含漱时CFU减少更多，具有高度统计学意义（p<0.001）。0.05%西吡氯铵可被视为金标准0.2%氯己定的一种有前景的替代物，温热含漱显示出明显优势。
