Comparative clinical study of the effect of LLLT in the immediate and late treatments of hypoesthesia due to surgical procedures

We evaluated the effect of LLLT in 68 patients who presented hypoegthesia due to odontological surgery procedures: dental implant surgeries (N=51); extraction of impacted lower third molars (N=10); endodontics in lower first molars (N=7).Lesions treated within 30 days after the nerve injury had occurred were part of the immediate group, and lesions with more than 30 days from the occurrence of the injury were part of the late group. mm(2),Treatments were carried out with an infrared diode laser of 40 mW - 830nm, continuous wave emission, spot size 3 and a total dosage of 18 joules per session in a contact mode application, 20 sessions altogether.The efficacy of laser therapy in peripheral nerve regeneration is also related to the degree of the peripheral nerve lesion, and not only to the lesion duration.LLLT resulted in neurosensory functional improvement in both immediate and late treatments of hypoesthesia.Universidade Federal de São Paulo, EPM, São Paulo, BrazilUniversidade Federal de São Paulo, EPM, São Paulo, BrazilWeb of Scienc
