Risk Factors of Inferior Alveolar Nerve Block Failure: a Dental Student-centered Study

Active, not recruiting

• Conditions: Anesthesia, Local

• Registration Number: NCT05681546
• Lead Sponsor: Selcuk 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.

Primary Outcome Measures

Name	Time	Method
Patrient-BMI index	after 5 minutes, patrients come to our clinic and sit on the dental unit.	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.
Patrient-Height of mandibular ramus	after 5 minutes, patrients come to our clinic and sit on the dental unit.	measuring of mandibular ramus on panoromic radyography from mandibular angulus to condylar head.
Patrient-Gender	after 5 minutes, patrients come to our clinic and sit on the dental unit.	attending patrients sex
Student-Class	after 5 minutes, patrients come to our clinic and sit on the dental unit.	attending dental students in which period for the explanation of their experiment level
Patrient-Maximum mouth opening	after 5 minutes, patrients come to our clinic and sit on the dental unit.	before the anesthasia, make the patrients open their mouth maximum then measure it from lower incisors incisal edge to upper incisors incisal edge.
Gender	after 5 minutes, patrients come to our clinic and sit on the dental unit.	attending dental studens sex
which side for the mandibular block anesthasia	after 5 minutes, patrients come to our clinic and sit on the dental unit.	Does the side of anesthesia according to the hand used affect its success?
Dental student-Mandibular nerve block experience	after 5 minutes, patrients come to our clinic and sit on the dental unit.	attending dental students in which period for the explanation of their experiment level
