A modified retraction technique was introduced into the DDS degree preclinical anesthesia course in 2011 with the goal of reducing needlestick exposure incidents. In numerous studies of dental exposures, injuries from dental anesthetic needles account for the highest proportion of all exposures. The purpose of this study was to assess the preliminary impact of a modified retraction technique on the incidence of blood and body fluids (BBF) exposure incidents associated with needles during injection. Data from evaluations of students from 2014 and 2015 were obtained and tracked to determine whether the modified retraction technique was "excellent," "clinically acceptable," or "clinically unacceptable." Data were collected to determine if the patient perceived the modified retraction technique as "comfortable" or "correctable when addressed" to help improve student technique for future injections. Likewise, data from the blood-borne exposure database where all information related to BBF exposures is recorded were reviewed and the information separated by year and class. This study presents preliminary data only and because of the small sample size does not lend itself to validation by statistical analysis. However, the technique effectively removes the operator's hand from the field during injection, reducing the risk of accidental intraoral needlestick to the nondominant hand of the operator.
2011年，一种改良的回缩技术被引入牙医学士学位临床前麻醉课程，目的是减少针刺暴露事件。在众多关于牙科暴露的研究中，牙科麻醉针造成的伤害在所有暴露中占比最高。本研究的目的是评估改良回缩技术对注射过程中与针头相关的血液和体液（BBF）暴露事件发生率的初步影响。获取并跟踪了2014年和2015年学生评估的数据，以确定改良回缩技术是“优秀”、“临床可接受”还是“临床不可接受”。收集数据以确定患者是否将改良回缩技术视为“舒适”或“提出问题时可纠正”，以帮助提高学生未来注射的技术。同样，对记录所有与BBF暴露相关信息的血源暴露数据库的数据进行了审查，并按年份和班级对信息进行了分类。本研究仅提供初步数据，由于样本量小，无法通过统计分析进行验证。然而，该技术在注射过程中有效地将操作者的手移出操作区域，降低了操作者非优势手意外口腔内针刺的风险。
