Brief Summary

This randomised control trial will compare the efficacy of conventional buccal nerve block versus buccal trunk block using visual analogue scale to evaluate pain and additional anesthesia injection during extraction of mandibular molars.

Detailed Description

Dental extraction of mandibular posterior teeth require buccal mucosa anesthesia for pain free extraction. Conventional buccal nerve block is the commonly used technique for anesthesia of buccal mucosa but often is not effective and requires multiple injections. This study aims to compare coventional buccal nerve block with buccal nerve trunk block on the basis of Efficacy of local anesthesia which will be determined by need for supplemental infiltration: Use of more than 1 anesthesia cartridges during procedure will be labelled as need for supplemental infiltration.

Intraoperative pain perception: It was assessed while giving injection and during extraction of the tooth using the visual analog scale (VAS) scores. Score of more than 4 will be labelled as positive pain perception.

Conditions

Pain (Visceral, Somatic, or Neuropathic)

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL

Study Groups

Conventional Buccal Nerve Block for anesthesia of buccal mucosa

Administration of anesthesia using conventional buccal nerve block technique for anesthesia of buccal mucosa.

Group Type: EXPERIMENTAL

Conventional Buccal Nerve Block

Intervention Type: PROCEDURE

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.

Buccal Nerve Trunk Block

Administration of anesthesia at the buccal trunk 10mm above the coventional buccal nerve block for anesthesia of buccal mucosa.

Group Type: EXPERIMENTAL

Buccal Nerve Trunk Block

Intervention Type: PROCEDURE

Arm Description: Administration of anesthesia 10 mm above occlusal plane lateral to last mandibular molar. 1ml lidocaine with 1:100000 anesthesia is administered.
