Outcome Measures
Primary Outcomes (2)
Intraoperative pain perception
It was assessed while giving injection and during extraction of the tooth using the visual analog scale (VAS) scores. Facial pain scale uses facial expression to evaluate the amount of pain. It has scores ranging from 0 to 10 with 0 as the least pain and 10 as the worst pain. Score of more than 4 will be labelled as positive pain perception.
Within 2hours of anesthesia administration
Need for supplemental infiltration
Use of more than 1 anesthesia cartridges during procedure will be labelled as need for supplemental infiltration.
Within 2 hour of initial anesthesia administration
Study Arms (2)
Conventional Buccal Nerve Block for anesthesia of buccal mucosa
EXPERIMENTALAdministration of anesthesia using conventional buccal nerve block technique for anesthesia of buccal mucosa.
Buccal Nerve Trunk Block
EXPERIMENTALAdministration of anesthesia at the buccal trunk 10mm above the coventional buccal nerve block for anesthesia of buccal mucosa.
Interventions
Arm Description: Administration of anesthesia at the level of occlusion lateral to last mandibular molar. Needle is inserted until bone contact is achieved. 1ml lidocaine with 1:100000 anesthesia is administered.
Arm Description: Administration of anesthesia 10 mm above occlusal plane lateral to last mandibular molar. 1ml lidocaine with 1:100000 anesthesia is administered.
