Health Condition 1: K029- Dental caries, unspecified

Interventions

Intervention1: IANB with LLLT: In LLLT (group I) , baseline pain assessment will be done by asking patients to irate their pain with placing a mark on a 100-mm VAS line before initiating the treatment
it is between the first and second metacarpal bones, at the midpoint of the second metacarpal bone, close to its radial border. To identify the point, the clinician will ask the patient to adduct the
Hegu is located at the highest point of the first and second metacarpal muscles. In LLLT group, laser irradiation will be applied using a 980-nm diode laser (Medency Primo 10 W Diode Laser, Vicenza, I
