Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Topical Anesthetic Solution

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.

Group Type ACTIVE_COMPARATOR

topical anesthetic

Intervention Type DRUG

Comparing the two versions (the room temperature and + 4°C) of the gold standard of local anesthetics, the solution, which contains lidocaine.

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.

Group Type EXPERIMENTAL

Topical anesthetic gel

Intervention Type DRUG

Tolerable taste, containing benzocaine at gel formula.

Cryotherapy as Distilled Water

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

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

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.

Group Type PLACEBO_COMPARATOR
