Background: Low-intensity laser therapy (LILT) can be utilized for different treatments in the field of orthodontics and dentofacial orthopedics. The aim of the present study was to evaluate the efficacy of LILT on (1) the rate of canine movement during canine retraction phase and (2) evaluate the radiographic changes occurring during LILT around the irradiated area.
Materials And Methods: A total of 10 patients of both genders were included for this study. One quadrant of the upper arch was considered control group (CG) and received mechanical activation of the canine teeth with 150 g. The opposite quadrant received the same mechanical activation and was also irradiated with a diode emitting light (gallium-arsenide laser) at 904 nm, for 10 s at 12 mW, at 4.2 J/cm(2). Laser application was done on 1(st) day, 3(rd), 7(th), 14(th), 21(th), 28(th), 35(th), 42(nd), 49(th), 56(th) day respectively during the canine retraction phase. Distance was measured on 1(st) day, 35(th) day and 63(rd) day and appliance activation was done on 1(st) and 35(th) day. Results were analyzed using t-test with the significance level set at P < 0.01.
Results: Mean value obtained from 1(st) to 63(rd) day was 3.30 ± 2.36 mm for CG and 3.53 ± 2.30 mm for laser group (LG).
Conclusion: There was no statistically significant difference in the rate of tooth movement during canine retraction between the LG and the CG. There was no evidence of any pathologic changes in the radiograph following LILT.

Background: In clear aligner therapy, tooth movement can be designed individually by computer software. However, the deformation of the aligner created by the virtual movement of one tooth may affect the actual movement of other teeth. This study aimed to evaluate the impact of the amount of canine movement on the responses of incisors and posterior teeth during maxillary anterior en-masse retraction with clear aligner.

This report describes a Belgian Malinois dog residing in metropolitan Phoenix, Arizona that was presented to a veterinary neurology center with abnormal eye movements as his only clinical sign. On examination, clinical signs were isolated to convergence-retraction nystagmus. A brain MRI was performed which identified two well-demarcated, T2-hypointense and T1-isointense, avidly contrast enhancing mass lesions with moderate to severe perilesional T2 and FLAIR hyperintensity within the left frontal lobe and left dorsal midbrain.

Objective: The trial was conducted to determine the effects of systemically delivered Vitamin D (1,25 dihydroxycholecalciferol) on the rate of maxillary canine retraction till the space closure and on the root resorption.
Materials And Methods: A two-arm parallel randomized controlled trial was conducted in patients with Angle's Class I bimaxillary protrusion requiring at least upper first premolars extraction and distal movement of canine for malocclusion correction. The enrolled patients were randomized and allocated to the experimental group (Oral Vitamin D = 0.

In order to reduce the prolonged duration of orthodontic treatment, several surgical techniques have been proposed over the years. Corticotomy and piezocision are the two most widely used techniques, and, given the lack of consensus in the literature, along with the renewed interest in these approaches in recent years, the primary objective of this study is to evaluate their effectiveness in accelerating canine retraction in patients requiring extraction of the upper first premolar and, as a secondary objective, to assess if there is a worsening of periodontal health and how the surgical approach is perceived by the patient. An electronic search was performed on PubMed, Scopus, Web of Science, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) up to 30 November 2024.

: The mechanical properties of either alveolar bone or periodontal ligaments under orthodontic loading, as well as orthodontic tooth movement, have been studied in recent years using computational approaches. In previous studies, we developed a theoretical mathematical approach that uses a weighting coefficient of the summed resistance of periodontal structures, namely the bone and periodontal ligaments, in relation to apex movement, the center of rotation, orthodontic force loading, and time in order to quantify the biological response to orthodontic biomechanics. : We analyzed the distal retraction of three maxillary canines and integrated the clinical data obtained in the previously developed mathematical programs.
