Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The main question it aims to answer are:
1. Does topical cooling reduce pain as effectively as topical benzocaine during greater palatine nerve block injections?
2. Is there any adverse reactions during and after application of topical ice and 20 % benzocaine gel?
3. Is there any difference in patient acceptability to the use of either methods during the administration of greater palatine nerve block.
A split mouth design was used where an anesthetic injection was administered in the left and right posterior palatal area. The same operator administered the injections so as to standardize the flow rate and delivery style. The method of intervention i.e topical ice or topical 20% benzocaine anesthetic gel was randomly allocated to the patient by lottery method. The participants received two palatal injections with an interval of two weeks between the appointments. The subjective pain response of the patients during greater palatine nerve block injection with pre-injection use of topical ice and topical anesthetic gel (20% benzocaine) was recorded using VAS scale. The objective pain response of the patients were recorded by a blinded single observer using SEM scale on the same day of the appointment.
Technique of application of topical ice: A new pack of sterile cotton swabstick that was injected with 0.5ml commercially available bottled water and then freezed the day before the appointment. At the time of intervention the injection site was dried with gauge piece and the frozen cotton swab stick was held by its wooden part and the frozen cotton end was placed on the proposed anesthetic site (palatal mucosa just anterior to the greater palatine foramen) for 1 minute. With the frozen cotton swabstick in place, an injection of 0.5 mL of 2 percent Lidocaine with 1:200,000 epinephrine was administered into the injection site via a 27-gauge short needle.
Technique of application of topical anesthetic gel: After the oral mucosa was dried with a gauze piece, application of 0.2 mL Benzocaine 20% gel was done with a sterile swab stick on the proposed anesthetic site (palatal mucosa just anterior to the greater palatine foramen) for a period of two minutes as shown in figure. With the cotton swabstick in place an injection of 0.5 mL of 2 percent Lidocaine with 1:200,000 epinephrine was administered into the injection site via a 27-gauge short needle.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Drug Arm :Topical benzocaine
since its a split mouth study one half of the hard palate will receive topical benzocaine i.e Group A
Topical Benzocaine
Benzocaine topical anesthetic gel will be used a pre-injection anesthetic on one half of the palate before giving greater palatine nerve block
Topical ice
Other half of the palate will receive topical ice i.e Group B
Topical ice
For the other half of the palate topical ice would be used before greater palatine nerve block
Interventions

Topical Benzocaine
Benzocaine topical anesthetic gel will be used a pre-injection anesthetic on one half of the palate before giving greater palatine nerve block
