Study population: In this study, the investigators are going to observe 320 IANB anesthesia in our clinic, which is the Oral and Maxillofacial Surgery Department of Selçuk University.

Brief summary: Inferior alveolar nerve block anesthesia is one of the most commonly used regional block anesthesia in dentistry. The factors that determine the success of this type of anesthesia which is applied so frequently, are not reported in the literature. It is to reveal and evaluate patient and dentist-based factors, especially in anesthesia applied by trainee dentists who have just learned this anesthesia block.

Detailed description: In this study, the investigators are going to observe 200 IANB anesthesia in our clinic. The investigators will evaluate the class, right/left handed, gender and experience on inferior alveolar nerve block of dental student. The criteria the investigators will evaluate for the patient are as follows; gender, body mass index, ramus height, left/right side, and maximum mouth opening amount. The criterion for the success of anesthesia are lost lip sensation within 10 minutes, no complication related to anesthesia.

Eligibility criteria: Inclusion Criteria:

* having an indication of mandibular first or second molar extraction,
* being between 18 and 50 years old,
* not having any nerve or nerve-related disease,
* having a mouth opening 35 millimeters and above,
* not having an infected or inflamed tooth for extraction,
* being cooperative,
* non-allergic to articaine
* being right-handed (for dental-students)
* being intern (for dental-students)

Exclusion Criteria:

* anesthesia-related complications,
* more than twice the needed needle insertion
* wishing to quit the study
