Local anesthesia has been reliably used to control pain during dental procedures and is important in pediatric dentistry. However, children occasionally complain of prolonged numbness after treatment, leading several problems. Studies conducted reverse the effect local using phentolamine mesylate photobiomodulation therapy (PBM) are encouraging but limited. PBM a type light that utilizes visible near-infrared non-ionizing electromagnetic spectral sources. Hence, this study modality compare reversal at two different wavelengths. This compared 660 810 nm wavelengths on soft tissue diode LASER dentistry.Informed consent assent were obtained, participants then divided randomly into three groups 20 each: group-without irradiation, irradiation nm, nm. Sixty aged 4-8 years with deciduous mandibular molars indicated for pulp administered an inferior alveolar nerve block. After 45 min injection, duration was similar approximate they exposed 660- 810-nm according their until achieved. The group did not undergo irradiation. anesthetic evaluated palpation pin prick tests every 15 min, cycle continued achieved.A significant reduction 55.5 (27.6%) mean time observed application wavelength 69 (34.7%) irradiation.PBM more effective reducing duration, thus can be as agent
