Effectiveness of Er:YAG laser-aided fiberotomy and low-level laser therapy in alleviating relapse of rotated incisors

The Effect of Low Level Laser Therapy on Direct Pulp Capping in Dogs

“…These energy densities were within the therapeutic window (between 0.01 and 10 J/cm 2 ) where biostimulatory effects of low power lasers are presented, whereas the inhibitory effects on physiologic activity can occur at higher dosages (greater than 12 J/cm 2 ). 31,32 The results of a meta-analysis study indicate that the use of 632 nm wavelength and energy density in the range of 0.5 to 4.0 J/cm 2 provided the most effective outcomes in cellular proliferation and thus caused a significant improvement in tissue repair. 33 Generally, contact mode is recommended for almost all laser applications with one exception: treating an open wound requires a 2 to 4 mm distance between the laser and the target tissue, providing a condition called non-contact mode.…”

Laser Surgery of Soft Tissue in Orthodontics: Review of the Clinical Trials

“…32 One of the studies compared laser with conventional scalpel technique for fiberotomy and the result showed efficacy of laser-aided fiberotomy in reducing rotational relapse. 30 In another study, laser operculectomy was done for one patient. 32 Six studies used diode laser.…”

“…19 Jahanbin et al used Er:YAG laser for fiberotomy. 30 Aras et al compared the effect of Er:YAG laser with diode laser in lingual frenectomy. 33 Although most articles applied diode laser in their procedures, there are differences among characteristics of irradiated diode laser exclusively in wavelengths and input power of lasers.…”

“…9, 19 Jahanbin et al used infiltration in target area. 30 Aras et al applied laser without any local anesthetic initially and compared diode laser with Er:YAG laser in treatment of tongue-tie. Sixteen patients were enrolled to this study in order to evaluate the acceptability of performing lingual frenectomy without the use of local anesthesia.…”

“…Another advantage of laser was sutures avoidance. In a study conducted by Jahanbin et al, 30 the efficacy of laser-aided circumferential supracrestal fiberotomy (CSF) was compared with conventional method of CSF in reducing relapse of corrected orthodontic rotation. Twenty-four patients who were at the finishing stage of orthodontic treatment were included in this study.…”
