Evaluation of adjunctive effect of low-level laser Therapy on pain, swelling and trismus after surgical removal of impacted lower third molar: A double blind randomized clinical trial

Abstract

Under limitations of this study, using low-power laser with mentioned parameters, clinically reduces pain, swelling and trismus after surgical removal of impacted mandibular wisdom, but not statistically significant.

Photobiomodulation in Oral Surgery: A Review

“…[13][14][15][16][17][18][19]31,[41][42][43] Twenty studies assessed the impact of PBM on postoperative trismus. 5,13,14,16,17,19,[24][25][26][28][29][30][31]33,34,[37][38][39]42,43 The wavelengths between 660 and 980 nm with power between 4 and 300 mW and 4-106 J/cm 2 energy density were reported as significant in reducing postoperative trismus in comparison with placebo. 13,14,16,19,31,42,43 In general, extraoral irradiation offered better results, especially for edema.…”

“…Nonsignificant impact of PBM on pain relief in comparison with placebo was observed in 10 articles. 23,[32][33][34][35][36][37][38][39][40] Eight of these latter studies applied *810 nm diode lasers 23,[34][35][36][37][38][39][40] with various powers (30-500 mW) and energy densities (2-60 J/cm 2 ). Facial swelling was assessed in 24 clinical trials.…”

“…Facial swelling was assessed in 24 clinical trials. 5,[13][14][15][16][17][18][19][24][25][26][28][29][30][31]33,34,[37][38][39][40][41][42][43] Among these studies, 10 articles represented significant decrease in facial swelling after PBM application (wavelength: 660-910 nm; power: 4-500 mW; energy density: 2-480 J/cm 2 ) compared with placebo. [13][14][15][16][17][18][19]31,[41][42][43] Twenty studies assessed the impact of PBM on postoperative trismus.…”

“…Farhadi et al 33 reported that 550 nm PBM adjuvant treatment is not clinically helpful for decreasing pain, swelling, and trismus. The authors concluded that administration of analgesics and antibiotics may play the most imperative role and camouflage the impact of PBM in these cases.…”

Terapia de fotobiomodulação após extração de terceiros molares inclusos. Estudo clinico randomizado duplo cego

“…Este mecanismo básico inicia uma cascata de sinalização celular, levando a uma otimização das funções corporais (26) No presente estudo, não foram observadas diferenças estatisticamente 5J/cm 2 ). (50) López-Ramírez et al (51) reportaram que a irradiação intra-oral com laser de baixa potência (810nm, 0.5W, 5J/cm 2 ) não produziu efeitos benéficos na diminuição de dor, edema e trismo após cirurgias de terceiros molares inclusos. Outros estudos como o Amarillas Escobar et al (58) Encontrar o ponto gonion é complicado, porque as características anatômicas do ângulo da mandíbula são arredondadas e é difícil identificá-lo através dos músculos, tecido celular subcutâneo e pele.…”
