Introduction:

The anesthetic technique to the inferior alveolar nerve (NAI) was compared between the performance by fourthand fifth-year students of the Dentistry career at the Andrés Bello University, Santiago.

Objective:

Was to evaluate the performance and success of the technique before a simple dental extraction.

Methods:

The students invited to participate signed an informed consent. A survey was conducted that contained an informative protocol for the student with the steps to follow, then, at the end of their clinical care, had to answer a series of multiple-choice questions.

Through this survey, it was evaluated how many students could achieve a correct inferior alveolar nerve block with only 1 tube of anesthesia lidocaine 2% and how many required additional anesthesia after having injected the first tube of anesthesia, before starting the surgical procedure.

Also, the amount of anesthesia tubes that the students used to perform the extraction in a painless way was quantified and how many required an additional anesthetic reinforcement intraoperatively. Thereby, a comparative analysis between both generations of students was carried out in relation to the use of the anesthetic technique.

Results:

Of the 104 participants, it was found that 57% of the 4th year students and 65% of the 5th year students achieved a correct anesthetic technique at the NAI with a single tube of anesthesia.

Conclusion:

There were no significant differences in relation to the academic year completed and the variables studied except for the need for anesthetic reinforcement after a successful anesthetic technique, where 4th year students needed to perform more intraoperative pain control.
