Comparing Pre-Anesthetic Approaches in Dentistry

The main purpose of this study is to find out which pre-treatment method works best to reduce pain from dental anesthesia injections in adult patients. Researchers will compare four different approaches: Topical numbing spray (10% lidocaine) Brief cold application (cryotherapy) A combination of both cold application and cooled numbing spray A control group Participants who need a standard local anesthesia injection for their dental treatment will be randomly assigned to one of these four groups. Right after the needle insertion, participants will rate their pain level using a simple visual scale, and their physical reactions will also be observed and scored by the researchers.
