Objectives

Narrative objectives1

Anesthetic area in the conventional buccal nerve block injecting local anesthetic at the mucous membrane of the anterior border of the ramus in
line with the occlusive plane never cross the
hight of parotid papilla. The aim of this study is
to examine if buccal nerve block with higher
injection position could across the the hight of
parotid papilla.

Results

The effective tactile sensory loss rate at 5 mm above the height of the papilla of the parotid duct of the premolar and molar regions were greater following BNTB (71 and 95%, respectively) than following conventional BNB (37%: p<.01 and 58%; p,.01, respectively).
The proportions of intraoperative pain perception of the BNTB group and the conventional BNB group were 10 and 42%(p=.06), respectively, and those of supplemental infiltration anesthesia ere 5 and 26% (p=.18), respectively.

Baseline Characteristics

The clinical study was performed at the Outpatient Clinic of the Division of Oral Implantology, the Nippon Dental University Hospital from September 8, 2021 to March 20, 2022.
The study population for the clinical trial included patients, aged 18 years or older, who had been scheduled for removal of a mandibular third molar.

Participant flow

Exclusion criteria were a history of hypersensitivity to lidocaine, paresthesia of the buccal gingiva and buccal mucosa, bleeding diathesis, use of anticoagulant or antiplatelet medications, and other medical history that might have affected the clinical trial (eg, uncontrolled hypertension or diabetes mellitus, heart failure, hyperthyroidism, psychiatric disorders).

Adverse events

There were no adverse events.

Outcome measures

The primary predictor variable was the approach for BNB (BNTB vs conventional BNB).
The primary outcome variable of interest was the extent of sensory loss of the buccal mucosa.
The secondary outcome variables were the anesthesia success rate of the
IANB for removal of third molars, and onset time and duration of BNBs.
The other study variables were age, sex, and injection side.
