Student-to-student administration of local anesthesia (LA) has been widely used as the teaching modality to train preclinical dental students. However, studies assessing students' outlook towards their first injection were limited. Therefore, this study aims to evaluate students' perception and anxiety levels towards their first LA injection.
Sixty three pre-clinical dental students swapped their roles as both operator and respondents in relation to their first supraperiosteal injection. After being injected, the students conferred their opinion and experiences to the questionnaire based on the five point Likert's scale and indicated their anxiety levels based on the Interval Scale of Anxiety response (ISAR). Their perception was described using frequencies and percentages and anxiety levels were statistically analysed using one way analysis variance and paired t test.
Students learning LA techniques directly on human subjects depicted not only greater confidence in them but also increased anxiety levels. The anxiety levels were found to be high before and during injection in both operator and respondent.
The students' preferred the use of preclinical models rather than student to student administration for their first LA injection exercise. Based on the results obtained, we recommend the need of preclinical simulation model in LA training program.
学生间局部麻醉（LA）给药已被广泛用作培训临床前牙科学生的教学方式。然而，评估学生对首次注射看法的研究有限。因此，本研究旨在评估学生对首次LA注射的认知和焦虑水平。
63名临床前牙科学生在首次骨膜上注射中交换了操作者和被试者的角色。注射后，学生根据五点李克特量表在问卷中表达他们的意见和经历，并根据焦虑反应间隔量表（ISAR）表明他们的焦虑水平。他们的认知用频率和百分比描述，焦虑水平用单因素方差分析和配对t检验进行统计分析。
直接在人体受试者上学习LA技术的学生不仅对其更有信心，而且焦虑水平也有所增加。在注射前和注射过程中，操作者和被试者的焦虑水平都很高。
学生在首次LA注射练习中更喜欢使用临床前模型而不是学生间给药。基于所得结果，我们建议在LA培训项目中需要临床前模拟模型。
