Apical root resorptions in girls with Turner syndrome: a controlled longitudinal study
ConclusionsThere is a higher risk for ARR in girls with TS and probably the risk is therefore probably also higher during orthodontic treatment. Thus, if treated, frequent radiographic follow-ups should be taken during the treatment.ProtocolThe protocol was not published before trial commencement.

Cost-effectiveness of orthodontics: a systematic review
ConclusionThis review highlighted a lack of economic evaluations for orthodontic interventions, and limitations of existing economic evaluations. Recommendations on future research are provided.RegistrationThe protocol for the systematic review was registered on the NIHR Database (www.crd.york.ac.uk/prospero, CRD42021220419).

Physical properties of root cementum: Part 29. The effects of LED-mediated photobiomodulation on orthodontically induced root resorption and pain: a pilot split-mouth randomized controlled trial
ConclusionThis 28-day randomized split-mouth controlled trial showed that daily, LED-mediated PBM application, when applied for 5 minute/day, does not influence orthodontic root resorption. It is associated with significantly less pain 24 hours after the application of orthodontic force, but no difference thereafter. These results should be tested on patients undergoing a full course of orthodontic treatment.Trial registrationClinical Trials Registry ACTRN12616000652471.

Using artificial intelligence to determine the influence of dental aesthetics on facial attractiveness in comparison to other facial modifications
ConclusionsAlignment of teeth improves facial attractiveness to a similar extent than wearing lipstick, but has no discernable effect on perceived age. Wearing glasses reduces attractiveness considerably, but this effect vanishes with age. (Source: The European Journal of Orthodontics)

Quality-of-life improvement, psychosocial benefits, and patient satisfaction of patients undergoing orthognathic surgery: a summary of systematic reviews
Conclusions and implicationsAesthetics and function are the main motives for seeking orthognathic surgery. Patient assessment before, during, and after orthognathic surgery is necessary for a thorough evaluation of self-perception and satisfaction throughout treatment. While psychological and social domains improved after orthognathic surgery treatment, the quality of life can deteriorate transiently during the pre-surgical orthodontic phase of treatment. A standardized assessment tool needs to be developed to assess quality-of-life changes consistently and provide comparable results.RegistrationCRD42020199091. (Source: Th...

Impact of melatonin on periodontal ligament fibroblasts during mechanical strain
ConclusionsExpression of melatonin receptors by PDLF enable them to detect fluctuating melatonin concentrations in the periodontal ligament. Melatonin increased collagen synthesis and expression of inflammatory mediators, but had no effect on genes involved in bone remodelling. Therefore, we suggest that melatonin has no accelerating effect on PDLF-induced osteoclastogenesis. (Source: The European Journal of Orthodontics)

The impact of non-extraction orthodontic treatment on oral health-related quality of life: clear aligners versus fixed appliances —a randomized controlled trial
ConclusionsPatients treated with clear aligners reported higher OHRQoL and shorter treatment duration as compared to those treated with fixed appliances.Trial registrationRetrospectively registered (DRKS-ID: DRKS00023977). (Source: The European Journal of Orthodontics)

Image quality assessment of three cone beam computed tomography scanners —an analysis of the visibility of anatomical landmarks
ConclusionsCBCT scans performed for orthodontic purposes using a large FoV with reduced parameters (400 µm, 2 to 4 mA and low dose protocols) are acceptable for visualization of large anatomical structures. Further lowering these parameters will not be sufficient to view small anatomical structures. Orthodontic indications will have to define specific anatomical structures to choose adequate scanning protocols to reduce dose and ensure reliable diagnostic visibility.

Assessment of the reliability of measurements taken on digital orthodontic models obtained from scans of plaster models in laboratory scanners. A systematic review and meta-analysis
ConclusionsNo statistical significance between the direct measurements on plaster models and the digital ones taken from laboratory scanners could be identified by means of random-effects meta-analysis.RegistrationThe systematic review was registered in the PROSPERO database (ID CRD42020215411).

Craniofacial changes from 13 to 62 years of age
Conclusions/ImplicationsCraniofacial changes continue up to the sixth decade of life. These changes are consistent, albeit to a lesser extent, with the adolescent growth patterns for most of the studied parameters, with the exceptions of incisor inclination, sagittal jaw position, vertical jaw relation and inclination, and posterior face height.

Effect of irisin on the expression of osteoclast-related genes in cementoblasts
ConclusionsOCCM-30 cells were responsive to the stimulation of irisin. The expression of RANKL and IL-6 was significantly enhanced by irisin, suggesting a possible promotive effect on cementoblast-mediated osteoclastogenesis. (Source: The European Journal of Orthodontics)

Colour assessment of bleaching effect on orthodontically treated teeth
ConclusionsPrevious exposure to fixed orthodontic appliance influenced the efficacy of external tooth bleaching. The effect of bleaching was higher after orthodontic treatment and with longer period in retention. Canines changed in colour more than incisors, and the effect was reduced over time.

A non-cephalometric three-dimensional appraisal of soft tissue changes by functional appliances in orthodontics: a systematic review and meta-analysis
ConclusionsCurrent evidence suggests a positive influence of the FA therapy on the soft tissues in Class II patients. However, conclusions were drawn based on a two-dimensional analysis of 3D images, suggesting that more controlled studies using a comprehensive 3D analysis are necessary to confirm these results.RegistrationPROSPERO registration (CRD 42021224016).

Chronological age range estimation of cervical vertebral maturation using Baccetti method: a systematic review and meta-analysis
ConclusionsFor each CVM staging a chronological age range was successfully estimated. Girls presented an earlier skeletal maturation compared to boys. The skeletal maturation differs also according to continents, except for CMV stage 1, pointing to the need for personalized ranges according to each region.RegistrationRegistration number: PROSPERO: CRD42021225422 (Source: The European Journal of Orthodontics)

Evaluation of palatal bone depth, cortical bone, and mucosa thickness for optimal orthodontic miniscrew placement performed according to the third palatal ruga clinical reference
ConclusionsBoth third palatal ruga and 2 mm posteriorly to third ruga (4 mm paramedian) could be the optimal insertion site for palatal miniscrew placement, depending on individual anatomic conditions. The thickness of the cortical palatal bone showed, at 4 mm paramedian, optimal characteristics for miniscrew primary stability. Palatal mucosa thickness values suggest miniscrew neck extension of 2.0 –2.5 mm for optimal mucosa adaptation. (Source: The European Journal of Orthodontics)
