INTRODUCTION
The novel COVID-19 which spread's primarily through oral and nasal passage poses a major threat of spread during dental treatments. It is important for dental practitioners to use minimal aerosol techniques. The aim of this study is to compare the time taken, efficiency and aerosol generated between modified and conventional technique (CT) of bracket bonding.
METHODS
This study includes 40 patients who required complete orthodontic treatment. In all 40 patients, one of the arches was bonded with modified technique (MT) and the opposing with CT. The time taken to prepare tooth in both the techniques were accessed. The efficiency of bond was seen over a period of 6 months. The amount of aerosol particulate matter generated during CT and MT was observed using a laser air quality monitor.
CONCLUSION
There is no significant difference in the bond failure and time taken between both the techniques. The aerosol generated in MT was minimal or almost negligible when compared to the use of CT.
引言
新型冠状病毒病主要通过口腔和鼻腔传播，在牙科治疗期间构成了主要的传播威胁。牙科从业者采用最小化气溶胶技术非常重要。本研究的目的是比较改良技术与传统技术（CT）在粘结托槽时所花费的时间、效率和气溶胶产生量。
方法
本研究纳入40例需要进行全面正畸治疗的患者。在所有40例患者中，其中一个牙弓采用改良技术（MT）粘结，相对的牙弓采用CT粘结。记录两种技术在备牙时所花费的时间。观察6个月期间的粘结效率。使用激光空气质量监测仪观察CT和MT过程中产生的气溶胶颗粒物数量。
结论
两种技术在粘结失败率和所花费时间方面无显著差异。与使用CT相比，MT产生的气溶胶极少或几乎可以忽略不计。
