The effect of light-emitting diode and laser on mandibular growth in rats

Abstract

The LED-treated groups showed more mandibular growth stimulation compared with the laser groups.

Adjunctive techniques for enhancing mandibular growth in Class II malocclusion

“…According to our knowledge, only one study, already referenced [34], has been performed so far. The results of this research indicated that LED has proved to effectively enhance mandibular growth in rats; and histologic data indicated that it significantly increased all condylar surface layers.…”

“…Further, on recent study comparing the effects between LED and LLL methods on mandibular growth of rats, LEDtreated animals demonstrated more mandibular growth than LLL groups [34].…”

“…Therefore, many experimental studies on animal models have been carried out in order to investigate alternative methods of stimulating mandibular growth, such as pulsed electromagnetic field [25,26], low-intensity pulsed ultrasound (LIPUS) [27][28][29][30][31][32][33], light emitting diode (LED) [34], low-level laser (LLL) [34], growth hormone [32], and gene therapy [33,35,36].…”

Histomorphometric Evaluation of the Effects of Mandibular Advancement Appliance and Low Level Laser Therapy (LLLT) with Different Doses on Condylar Cartilage and Subchondral Bone in Rats

“…Many studies have shown that biomechanical stimulus are important for development and growth process of secondary cartilages like mandibular condyle cartilage (Tingey & Shapiro, 1982;Peltomäki et al, 1997). Through the development of new methods and technologies some researchers studied to increase the chondroblastic and osteoblastic activity in mandibular condylar cartilage with laser and ultrasound for mandibular condyle growth stimulation and acceleration with, or without functional appliances in experimental animals (Oyonarte et al, 2009;Seifi et al, 2010;El-Bialy et al, 2015). Low level laser therapy (LLLT) is gaining popularity in medical and dental fields in last years.…”

“…Low level laser therapy (LLLT) is gaining popularity in medical and dental fields in last years. In recent experimental animal studies, LLLT has become a foremost way to accelerate and stimulate the condylar cartilage growth and mandibular advancement with or without functional appliance (Seifi et al;Abtahi et al, 2012;El-Bialy et al, 2015).…”
