This national survey provides documentation regarding typical orthodontic practice patterns in the United States, including the prevalence of percutaneous injuries. The sample reflects a similar geographic distribution of the population as a whole, with more practitioners located in areas with higher populations. Most practitioners in this sample were in solo full-time practice, averaging 35 hours per week, and treating patients for 47 weeks per year. A 20-day prospective period was used to collect data regarding exposure to percutaneous injuries. The study identified a mean percutaneous injury rate of 0.085 during a 20-day period for practicing orthodontists, a value that can be extrapolated to slightly less than one (0.99) percutaneous injury per orthodontist per year. The majority of these injuries (84%) occurred outside the mouth. This rate is approximately one third the rate reported for dentists in general practice.
这项全国性调查提供了有关美国正畸临床实践典型模式的资料，包括经皮损伤的发生率。样本反映了与整个人口相似的地理分布情况，人口较多地区的从业者更多。该样本中的大多数从业者为独立全职执业，平均每周工作35小时，每年治疗患者47周。采用20天的前瞻性时间段来收集经皮损伤暴露的数据。该研究确定，执业正畸医生在20天期间的经皮损伤平均发生率为0.085，据此推算，每位正畸医生每年的经皮损伤略少于1次（0.99次）。这些损伤中的大多数（84%）发生在口腔外。该发生率约为普通牙科医生报告发生率的三分之一。
