The Effect of Er,Cr:YSGG Laser-assisted Topical Anesthetic on Oral Mucosal Anesthesia

This study tests whether using an Er,Cr:YSGG laser before applying numbing gel (lidocaine) can help reduce pain during dental procedures compared to traditional methods. Investigators want to know: Does the laser make the numbing gel work better and longer? Does it lower pain and keep patients calmer (measured by heart rate)? Investigators enrolled 20 adults (10 men, 10 women) and assigned them to three groups: Laser + Numbing Gel: Laser was used on the gums before applying lidocaine. Sham Laser + Numbing Gel: A fake laser was used with lidocaine. Sham Laser + Vaseline: A fake laser was used with Vaseline (no numbing effect). Participants reported pain levels on a scale (0=no pain, 10=worst pain) when a tiny needle touched their gums. Investigators also checked their heart rate.
