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.
