Online published on 31 March, 2020. Abstract Low level laser therapy is very promising method to treat temporomandibular joint disorders, the aim of this study was to assess the effectiveness of different energy density of 940nm diode laser, 120 Westar albino male rats (250g weight, three months old) were used in this study, divided randomly into four experimental groups; negative control group injected with saline, positive control group injected with carrageenan solution with no treatment, study group injected with carrageenan and treated with 171J/cm2 LLLT group, and study group injected with carrageenan and treated with 74J/cm2 LLLT group, animals were euthanized in day;1, 3, and 7, histological slides obtained and examined under light microscope for assess acute and chronic inflammatory infiltrations. It was concluded that LLLT using 74J/cm2 energy density had a very efficient anti-inflammatory effect. Top Keywords Anti-inflammatory, effectiveness, carrageenan, arthritis. Top |
