Use of LLLT to accelerate orthodontic tooth movement in animals.

Author name	Sample	Laser type	Energy	Results	Movement in experimental group (mm)	Movement in control group (mm)
Shirazi et al. [39]	30 rats divided into 2 groups, 15 each	GaAlP diode; 660 nm; Continuous wave mode; 25 mW; 660 nm	7.5 J/session; 5 min/session after every 48 hrs; for a total of 6 sessions	2.3-fold acceleration in tooth movement in laser irradiated group	0.39 ± 0.07	0.11 ± 0.04
Altan et al. [40]	38 male Wistar rats divided into 4 groups: 3 experimental groups = 11 rats each, 1 control group = 5 rats	GaAlAs; 820 nm; Continuous mode 100 mW	One group received; 54 J/session; The other group received 15 J/session applied daily for 8 days	No statistically significant result	Not mentioned	Not mentioned
Kim et al. [42]; (combination with corticision)	12 beagle dogs; Maxillary 2nd premolars () divided into 4 groups (); Split mouth design	GaAlAs; 808 nm; Pulsed mode; 763 mW	75 mJ per pulse 41.7 J/cm^2/point 333.6 J/cm^2/session; Applied every 3rd day for 8 weeks	LLLT accelerated tooth movement 3.75-fold; Corticision accelerated tooth movement 3.76-fold; No significant difference in tooth movement in LLLT + corticision group	4.62 ± 0.25; 4.61 ± 0.30; 0.88 ± 0.19	0.23 ± 0.18
