Effect of low-level laser treatment on neurosensory deficits subsequent to saggittal split ramus osteotomy

Complications of Orthognathic Surgery

“…1,16,25 Using objective tests as detection means, the percentage of lesionaffected nerves after mandibular osteotomy ranges between 9% and 85.5%, and using subjective tests, between 9% and 100%. 13,26 Moreover, Panula et al 5 reported a 0% to 94% variability, depending on the sensibility of the tests used and on the follow-up period. 8 In a study of Colella et al,8 in which multiple related studies were taken into account, the mean percentage of the damaged nerves resulting from postoperative subjective tests performed 1 year after surgery is 23.8%.…”

Clinical and Radiographic Investigation of the Adjunctive Effects of a Low-Power He-Ne Laser in the Treatment of Moderate to Advanced Periodontal Disease: A Pilot Study

“…31 Other therapeutic low-power lasers such as diode, indium-gallium-aluminum-phosphide (InGaAlP), gallium-aluminum-arsenide (GaAlAs), and gallium-arsenide (GaAs) lasers have also demonstrated positive effects. [26][27][28][29]32 The popularity of these lasers can be explained in part by the fact that they are inexpensive, small, and sturdy. The present clinical trial showed that the adjunctive use of a He-Ne low-power laser when used as an adjunct to non-surgical periodontal therapy in patients with moderate to advanced chronic periodontitis did not enhance the healing response as assessed by both clinical and radiographic parameters, although there was a statistically significant difference in GCF volume between test and control sites at 3 mo.…”

“…15 Low-power lasers have been the focus of basic research in the past decade on their stimulatory effects on various cells in vitro [16][17][18][19][20] and in animals. 21,22 Many therapeutic claims for the use of low-power lasers in dentistry have also been reported, including management of aphthous ulcers, 23 reduction of pain and discomfort, 24,25 treatment of dentine hypersensitivity, 26 and neurosensory recovery after surgical procedures in the head and neck region, [27][28][29] where positive results have been reported. Masse et al 30 found no effect of low-power laser therapy on healing after periodontal surgery, while Neiburger 31 found a biostimulatory effect on the rate of gingival wound healing following application of helium-neon (He-Ne) diode laser energy.…”

Low level 809‐nm diode laser‐induced in vitro stimulation of the proliferation of human gingival fibroblasts

“…Considerable basic research has been undertaken since the 1970's. Latest investigations, in particular animal [4][5][6][7][8][9][10][11] and well controlled clinical studies in the field of dentistry [12][13][14][15][16][17][18], however, were often contradictory about the presumed benefits of the laser treatment. Difficulties in measuring operating variables related to pain and tissue repair in an animal model or a clinical setting emphasizes the need of basic cellular research on laser biology.…”
