Clinical Trial Summary

To study the patients' and dentists' perception of receiving/ administering maxillary buccal infiltration anesthesia using an open or closed mouth techniques

Description:

Background: Local anesthesia is an essential part of dentistry. The most commonly used technique to anesthetise maxillary posterior teeth is buccal infiltration with a local anesthetic agent. The technique described in the literature focuses on the location of injection, the direction of the needle insertion in relation to the root apex, the direction of needle bevel in relation to the cortical bone plate, the size of needle and the type and amount of the local anesthetic agent used. However, there is no mention to whether the patient should open their mouth or maintain their teeth in intercuspation during the injection procedure. Aims: This research aims to a) compare two techniques of injection (open and closed-mouth techniques) in terms of the discomfort experienced by patients during the injection procedure and b) evaluate the dentists' preference in performing either of the two techniques.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient Pain Perception	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.	5 minutes after receiving the injection
Secondary	Dentist Perception of Visibility During Anesthesia Injection	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.	30-60 days
Secondary	Dentist Preference of Performing One of the Two Techniques of Maxillary Buccal Infiltration; Open-mouth or Closed-mouth	Number of dentists preferring each technique	3-60 days
