The effects of adding low energy laser irradiation after skin resurfacing in lowering complication. Laser Surg Med. Abstract issue, 2002, abstract 242.
Fereydson E, Samieh M. Laser therapy is a valuable supportive therapy after skin resurfacing with CO2 laser. In a study by Fereydson.
Twenty patients had full face skin resurfacing with superpulse CO2 laser, 500 mJ/cm2. Ten patients had additional 780 nm laser therapy. This additional therapy lowered complications such as pain, erythema, infection rate and itching. Bone repair of the periapical lesions treated or not with low intensity laser (wavelenght=904 nm).

Sousa G R, Ribeiro M S, Groth E B. The effect of bone repair in periapical lesions has been studied by Sousa []. 15 patients with a total of 18 periapical lesions were divided into two groups. One group received endodontic treatment and/or periapical surgery. The patients in the other group were submitted to the same procedure and in addition the lesions were irradiated by GaAs laser, 11 mW, 9 J/cm2. This therapy was performed during 10 sessions with an interval of 72 hours. Bone regeneration was evaluated through X-ray examination. The results showed a significant difference between the laser and the control group in favour of the laser group.

Silveira L B, Ribeiro M S, Garrocho A A et al. The effect of laser therapy in periodontal surgery has been reported by Silveira. 20 patients with periodontal disease were subjected to gingivectomies. Gingival biopsies were taken from a non-mineralised wall of a suprabony periodontal pocket. The first sample was taken before laser irradiation, the second after 785 nm laser irradiation and the third after 688 nm laser irradiation (50 mW, 8 J/cm2). After biopsy the samples were fixed, cut and stained. Both laser wavelengths promoted mast cell degranulation as compared to control and there was no statistical difference between the two wavelengths.

Sawazaki I, Ribeiro M S, Mizuno L T et al. A The effect of toluidine blue and laser in combination has been studied by Sawazaki. Eight patients with inflammatory fibrous hyperplasias caused by ill-fitting dentures were selected for the study. Each hyperplasia was randomly divided into three areas. One was surgically removed without any treatment; one was treated by a 670 nm laser, 15 mW, 8 J/cm2 and then removed. The third part was dyed with TBO, and laser treated in the same way as part two. Mast cell degranulation in the control specimens was average 49´%, in the laser specimens 87% and in the combined TBO/laser specimens 88%. With these parameters the TBO did not have any additional effect Clinical evaluation of the low intensity laser antialgic action of GaAlAs (wavelenght=785 nm) in the treatment of the temporomandibular disorders.

Sanseverino N T M, Sanseverino C A M, Ribeiro M S et al. The improved outcome of laser therapy, if higher doses are given, is documented in the study by Sanseverino 10 patients with pain and limitation of movements of the jaw were treated by 785 nm GaAlAs laser, dose 45 J/cm2. The joint and tender points in the masticatory and otherwise involved muscles was applied three times per week during three weeks. A control group of 10 patients was given sham laser therapy. The evaluation was performed through subjective pain assessment and measurement of the movements of the jaw. There was a significant improvement in the laser group only |
