在牙科治疗过程中的疾病传播和屏障技术是近年来牙科界关注的领域。众所周知，超声波清洗机会产生气溶胶，这些气溶胶通常来自包括出血在内的重大疾病活动区域。这项研究是为了确定这些气溶胶是否含有牙龈沟的血液。由两个相邻的牙周受损伤牙齿组成的40个区域（每颗牙齿的探探深度至少为5毫米）用超声刮尺在龈下刮尺30秒。一个高容量疏散器（HVE）尖端被放置在距离操作地点3至5厘米的地方，用于捕获产生的气溶胶。用桂皮树脂法对HVE管内及管外残留的水进行潜血检测。记录牙龈指数、平均探诊深度、有无结垢出血以及HVE尖端有无可见血液。尽管测量参数差异很大，但所有40个测试点都显示捕获的气溶胶中血液呈阳性。由此可以得出结论，在牙周病牙齿的牙龈下用超声刮垢器刮垢可能会产生含有血液的气溶胶。
DISEASE TRANSMISSION AND BARRIER TECHNIQUES during dental treatment have been areas of recent concern in dentistry. Ultrasonic scalers are known to produce aerosols, and these aerosols are often produced from areas of significant disease activity, including bleeding. This study was performed to determine if these aerosols contain blood from the gingival sulcus. Forty areas consisting of two contiguous periodontally involved teeth (probing depth of at least 5 mm on one site of each tooth) were scaled subgingivally with an ultrasonic scaler for 30 seconds. A high volume evacuator (HVE) tip was positioned 3 to 5 cm away from the operating site and utilized to capture the aerosols produced. The water remaining in and on the HVE tube was tested for occult blood by the guiac resin method. Gingival index, mean probing depth, presence of bleeding with scaling, and presence of visible blood in the HVE tip were recorded. All 40 test sites showed a positive result for blood in the captured aerosols despite the wide variation in the measured parameters. It may be concluded that subgingival scaling on periodontally involved teeth with ultrasonic scalers would be expected to produce aerosols containing blood.
