“…The same finding was mentioned in other four different studies (12,15,18,19) . All of previously mentioned studies reported a higher ratio of the rate of canine retraction in the study group than in the present study; through their different study periods (4 months, 1 month, 3 months and 1 month respectively).…”

“…The results of the present study concluded that low level laser had stimulatory effect on acceleration of orthodontic tooth movement agreed with the findings which were reported by many human studies (3,11,12,13,14,15,16,17,18,19) and disagreed with other studies which showed no effect on tooth movement (20,21,22) . This controversial results in the previous studies may be due to the different energy densities they used; which mentioned in Arndt-Schulz law; who stated that low doses have stimulatory and high dosages have inhibitory effects (23) or may be due to the longer wavelengths they used (8) .…”

Objective: to evaluate the effect of low intensity laser therapy on the rate of orthodontic tooth movement in adolescent females. Materials and Methods: A sample of 10 patients with an age range of 14-18 years requiring extraction of first premolars was selected for this study. A randomized split-mouth study design was used. A nickeltitanium closed-coil spring was used for canine retraction on mini-implants. The study side received low intensity laser therapy (LILT) from a semiconductor (aluminium gallium arsenide) diode laser with a wavelength of 910 nm. The laser regimen was applied on days 0, 3, 7, and 14 in the first month, and thereafter on every 15th day until complete canine retraction was achieved on both sides. Tooth movement was measured on progress models every 60 days. Results: The rate of canine retraction showed statistical significant higher rate on study side than that on the control side. Conclusions: The results revealed that, the ratio of the rate of orthodontic tooth movement of the laser side to the control side was (1.09); throughout the study period which was 6 months.

“…Our study is in accordance with a study conducted by Genc G, Kocadereli I, Tasar F, Kilinc K, El S, Sarkarati B (2013)[ 9 ] to evaluate the effects of LLLT on (1) the velocity of orthodontic tooth movement and (2) the nitric oxide levels in gingival crevicular fluid (GCF) during orthodontic treatment. In this study sample size was 20 patients (14 girls, six boys) whose maxillary first premolars were extracted and the canines were distalized.…”

A comparison of the rate of retraction with low-level laser therapy and conventional retraction technique

Background and Objectives:A major concern of orthodontic patients is treatment time. Reducing the treatment time requires increasing the rate of orthodontic tooth movement. Research has proved that bone resorption is the rate-limiting step in tooth movement. Therefore, any procedure that potentiates osteoclastic activity is capable of increasing the rate of orthodontic tooth movement. Low-level laser has been indicated to have the capability to facilitate the differentiation of the osteoclastic and osteoblastic cells, which are responsible for the bone remodeling process. The purpose of this study was to evaluate whether the low-level laser therapy can accelerate orthodontic tooth movement during en masse retraction.Method:The study was a split-mouth design. The experimental side was exposed to biostimulation using 810 nm gallium-aluminium-arsenide diode laser. A total of 10 irradiations for 10 s per site were given 5 on the buccal side and 5 on the palatal side of the tooth. The total energy density at each application was 10 J with an interappointment gap of 3 weeks. The retraction was carried using a constant force of 150 gm. A digital vernier caliper measurement was used to measure the distance between the contact points of the maxillary canine and second premolar on 1st and 84th day.Results:The rate of orthodontic tooth movement was faster on the experimental side, and the difference between the two sides was statistically significant (P < 0.014).Interpretation and Conclusion:It was concluded that biostimulation carried out using an 810 nm diode laser is capable of increasing the rate of extraction space closure. Hence, it is capable of increasing the rate of orthodontic tooth movement.

“…One of those protocols involves laser irradiation on days 0, 3, 7, 14, and then every 2 weeks(7, 13). Consequently, protocols requiring less patient recall have been advocated, such as that suggested by Garg et al (14), and Qamruddin et al (15,16), in which LLLT irradiation has been applied every 3 weeks.…”

Objective: Low-level laser therapy (LLLT) has been found to accelerate the rate of tooth movement, which in turn may aid in preserving posterior anchorage. However, one of the drawbacks of LLLT, is the high frequency of patient recall. The aim of the study was to evaluate and compare the amount of molar anchorage loss accompanying canine retraction, by employing two LLLT protocols, involving a high and a low application frequency.Materials and Methods: Sixteen patients were enrolled, in which the therapeutic extraction of maxillary 1 st premolars was required for orthodontic treatment, with subsequent canine retraction. Patients were equally and randomly divided into 2 groups. In Group A, LLLT was randomly administered to one side of the maxillary arch on days 0, 3, 7, 14, and then every 2 weeks, while in Group B, one side of the maxillary arch was randomly selected for LLLT application every 3 weeks. The administered LLLT was a Diode laser with a 980 nm wavelength. Canine retraction was carried out using closed-coil springs, with 150 grams of force, and the amount of mesial molar movement was checked every 3 weeks, over the 12-week study period.Results: Equivalent amounts of mesial molar movements have been displayed with and without LLLT application, in both study groups. Also, no significant differences have been documented between the laser sides in groups A and B. Conclusion: Molar anchorage has not been augmented by LLLT, whether applied with a high frequency, or with less frequent applications coinciding with the follow-up visits.
