Should Maxillary Buccal Infiltration Anesthesia be Given in a Closed Mouth Technique?

University of Jordan120 enrolled

Overview

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

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.

Outcomes

Primary Outcomes

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.

Time frame: 5 minutes after receiving the injection

Secondary Outcomes

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.

Time frame: 30-60 days

Dentist Preference of Performing One of the Two Techniques of Maxillary Buccal Infiltration; Open-mouth or Closed-mouth

Number of dentists preferring each technique

Time frame: 3-60 days
