Patient Pain Perception Primary · 5 minutes after receiving the injection

Pain perception during local anesthesia injection on a standard 100mm visual analogue scale (VAS) where zero indicates no pain at all and 100 indicates intolerable pain/ worst imagined pain (scale attached in the protocol section). The average scores were calculated for each group and compared. Higher values indicated higher pain/ discomfort experienced during the injection procedure.

Group	Value	95% CI
Open-mouth	32.6	± 15.8
Closed-mouth	25	± 14

Dentist Perception of Visibility During Anesthesia Injection Secondary · 30-60 days

Participating dentists were asked to rate the visibility of injection site and ease of cheek retraction during injection on a standard 100mm visual analogue scale where 100 indicates the best possible visibility/ easiest cheek retraction and 0 means no visibility at all/ most difficult cheek retraction. The mean scores were compared between the 2 groups using independent t-test.

Visibility during injection

Group	Value	95% CI
Open-mouth	68.1	± 17.1
Closed-mouth	82.6	± 14.3

Ease of cheek retraction

Group	Value	95% CI
Open-mouth	64.9	± 20.1
Closed-mouth	83.2	± 12.7

Dentist Preference of Performing One of the Two Techniques of Maxillary Buccal Infiltration; Open-mouth or Closed-mouth Secondary · 3-60 days

Number of dentists preferring each technique

Group	Value	95% CI
Open-mouth	3
Closed-mouth	38
