Study 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.

Read the 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.

What researchers measure

Primary outcomes

  1. Patrient-BMI index

    Ask the patrients their weight and height then note that as their bmi index.This note guides us amount of bichat and how it affects the failure of block anesthasia.

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  2. Patrient-Height of mandibular ramus

    measuring of mandibular ramus on panoromic radyography from mandibular angulus to condylar head.

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  3. Patrient-Gender

    attending patrients sex

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  4. Patrient-Maximum mouth opening

    before the anesthasia, make the patrients open their mouth maximum then measure it from lower incisors incisal edge to upper incisors incisal edge.

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  5. Gender

    attending dental studens sex

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  6. Student-Class

    attending dental students in which period for the explanation of their experiment level

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  7. Dental student-Mandibular nerve block experience

    attending dental students in which period for the explanation of their experiment level

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.

  8. which side for the mandibular block anesthasia

    Does the side of anesthesia according to the hand used affect its success?

    Time frame: after 5 minutes, patrients come to our clinic and sit on the dental unit.
