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

Condition or disease Intervention/treatment Phase
Anesthesia, Local Pain Control Procedure: Local anesthesia Not Applicable

Detailed 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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 120 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Providing dental local anesthesia (maxillary buccal infiltration) using two techniques; open-mouth and closed-mouth
Masking: None (Open Label)
Primary Purpose: Other
Official Title: Should Maxillary Buccal Infiltration Anesthesia be Given in a Closed Mouth Technique? - a Clinical Study
Actual Study Start Date : April 29, 2019
Actual Primary Completion Date : June 20, 2019
Actual Study Completion Date : June 23, 2019

Arm Intervention/treatment
Active Comparator: Open-mouth
Patients receiving maxillary buccal infiltration anesthesia (MBIA) with their mouth wide open
Procedure: Local anesthesia
Patients scheduled for a dental procedure that requires local anesthesia will be given the injection using two 2 techniques; an open-mouth and closed-mouth techniques

Experimental: Closed-mouth
Patients receiving MBIA using a closed-mouth technique
Procedure: Local anesthesia
Patients scheduled for a dental procedure that requires local anesthesia will be given the injection using two 2 techniques; an open-mouth and closed-mouth techniques




Primary Outcome Measures :
  1. Patient Pain Perception [ Time Frame: 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.


Secondary Outcome Measures :
  1. Dentist Perception of Visibility During Anesthesia Injection [ Time Frame: 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.

  2. Dentist Preference of Performing One of the Two Techniques of Maxillary Buccal Infiltration; Open-mouth or Closed-mouth [ Time Frame: 3-60 days ]
    Number of dentists preferring each technique
