• Interventions: Drug: topical anesthetic; Drug: Topical anesthetic gel; Drug: Cryotherapy; Drug: Placebo

• Registration Number: NCT07198022
• Lead Sponsor: Ondokuz Mayıs University

Brief Summary

In this study, we aimed to compare the effects of topical anesthetic materials and cold application on pain perception. The main questions it aims to answer are:

* Is cold application is effective as a topical anesthetic replacement?

* Is there a difference on pain perception between cold and room temperature topical anesthetic?

The treatment contains of participants selected from a group of patients who requires dental treatment. Their mission is to answer the questionnaires correctly and cooperate the treatment. Participanst will be divided into 5 groups containing 25 child per group:

* First group: topical anesthetic solution.

* Second group: topical anesthetic gel

* Third group: Cryotherapy as distilled water

* Fourth group: Cryotherapy as topical anesthetic solution.

* Fifth group: Placebo group All participants will answer questionnaire of pain, anxiety and taste. Their oxygen saturation and pulses will be measured with a pulse-oxymeter device to be recorded.

Arm && Interventions

Group	Intervention	Description
Topical Anesthetic Solution	topical anesthetic	In spray group, as a topical anaesthetic solution containing 10% lidocaine will be applied to the injection site with the help of a pressel for 20 seconds after the application area is dried by squeezing a cotton pellet. The taste/odour evaluation of the applied topical anaesthetic material will be measured with the 3 Category Hedonic Scale. After sufficient numbness is achieved, local infiltrative injection will be performed. Anxiety levels will be evaluated by measuring with the same parameters before topical anaesthesia application, during topical anaesthesia application and injection.
Topical Anesthetic Gel	Topical anesthetic gel	In topical anesthetic gel group, a gel containing %20 benzocain with strawberry aroma, will be applied to the injection site with the help of a pressel for 20 seconds after the application area is dried by squeezing a cotton pellet. The taste/odour evaluation of the applied topical anaesthetic material will be measured with the 3 Category Hedonic Scale. After sufficient numbness is achieved, local infiltrative injection will be performed. Anxiety levels will be evaluated by measuring with the same parameters before topical anaesthesia application, during topical anaesthesia application and injection.
Cryotherapy as Distilled Water	Cryotherapy	As cryotherapy material, distilled water solution will be cooled in the refrigerator at +4 degrees, removed from the refrigerator just before the application and a cotton swab will be wetted with this solution and applied to the area. The taste/odour evaluation of the applied topical anaesthetic material will be measured with 3 Category Hedonic Scale. After sufficient numbness is achieved, local infiltrative injection will be performed. Anxiety levels will be evaluated by measuring with the same parameters before, during and after topical anaesthesia application and injection.
Cryotherapy as Anesthetic Solution	Cryotherapy	The topical anaesthetic solution will be stored in the refrigerator at +4 degrees Celsius, removed from the refrigerator just before the application and a cotton swab will be wetted with this solution and applied to the area. The taste/odour evaluation of the applied topical anaesthetic material will be measured with 3 Category Hedonic Scale. After sufficient numbness is achieved, local infiltrative injection will be performed. Anxiety levels will be evaluated by measuring with the same parameters before, during and after topical anaesthesia application and injection.
Cryotherapy as Anesthetic Solution	topical anesthetic	The topical anaesthetic solution will be stored in the refrigerator at +4 degrees Celsius, removed from the refrigerator just before the application and a cotton swab will be wetted with this solution and applied to the area. The taste/odour evaluation of the applied topical anaesthetic material will be measured with 3 Category Hedonic Scale. After sufficient numbness is achieved, local infiltrative injection will be performed. Anxiety levels will be evaluated by measuring with the same parameters before, during and after topical anaesthesia application and injection.
Placebo	Placebo	The group who chooses the number 5 which implies placebo, will be informed to have the standard topical anesthetic spray. The procedure will be conducted with only dry cotton pellet implementation for 20 seconds, then waiting after waiting for a while, injecting the local anesthetic to the related area. Pulse and oxygen saturation will be recorded identically as the other groups.

Primary Outcome Measures

Name	Time	Method
Number of Participants with Eased Injection Pain	From the beginning of the topical anesthetic implementation to the injection	During the procedure, all of the data of the participants containing oxygen saturation, pulse and questionnaire about their experience will be collected to assess the statistical differences between groups.
