ABSTRACT Objective: The aim of this study was to evaluate the effect of LPRF, placed in extraction sockets, on orthodontic tooth movement (OTM). Materials and Methods: Thirty extraction sockets from eight patients (five males, three females, with a mean age of 17.37 years; range 12–25 years) requiring extraction of first premolars based on their orthodontic treatment plan participated in this split-mouth clinical trial. In one randomly selected quadrant of each jaw, the extraction socket was preserved as the experimental group by immediate placement of LPRF in the extraction socket. The other quadrant served as the control group for secondary healing. Immediately, the teeth adjacent to the defects were pulled together by a NiTi closed-coil spring with constant force. A piece of 0.016 × 0.022-inch stainless steel wire was used as the main arch wire. The amount of OTM was measured on the study casts at eight time points with 2-week intervals for 3 months. Analysis of random effect model was performed for the purpose of comparison between the experimental and control groups. Results: According to the random effect model, a statistically significant difference was found between the experimental and control group in rate of OTM (P = 0.006). Conclusion: According to the results, application of LPRF, as an interdisciplinary approach combining orthodontics and surgery, may accelerate OTM, particularly in extraction cases.

Introduction: The objective of the study was to assess the rate of canine retraction and secondary outcomes associated with conventional fixed orthodontic treatment (CFO) and CFO with micro-osteoperforation (CFO + MOP), that is, anchorage loss, root resorption, vitality of tooth, pain and discomfort level during the procedure. Methods: A total of 16 patients with Class II Division 1 malocclusion who required upper first premolar extraction with lower non-extraction/single incisor extraction were divided into the test group (MOP) and positive control group (CFO + MOP) for a split-mouth study. Both maxillary canines were retracted with nickel–titanium (NiTi) closed coil springs. Patients were reviewed after 24 hours, 7 days, 28 days, and 4, 8, and 16 weeks to assess the rate of tooth movement, anchorage loss, root resorption, vitality of tooth, pain and discomfort level. Results: There was a statistically significant difference in the rate of tooth movement between the CFO and CFO + MOP groups after the first 4 weeks ( P-value = .026), whereas no statistically significant difference was observed at 8, 12, and 16 weeks ( P-value = .33, .99, and .08, respectively). In the CFO group, there was no statistically significant difference in tooth movement between different time intervals ( P-value > .05). There was no significant difference in root resorption between the groups. The pain level was higher in the MOP group in the first 24 hours ( P-value < .05) after the procedure. Later on, the difference in pain level between the groups was not significant ( P-value > .05). The vitality of retracted canines in both groups was healthy. Conclusion: The study recommends that the CFO + MOP procedure has substantial potential to be used as an adjunct to the routine mechanotherapy for faster tooth movement, as it may reduce the treatment time by half in the first 4 weeks after the MOP procedure. There are no potential differences in anchorage loss, tipping, vitality, and apical and lateral root resorption between the CFO and CFO + MOP groups. This trial was registered at Clinical Trial Registry, India.

ABSTRACT Objectives: To investigate the canine retraction rate and anchorage loss during canine retraction using self-ligating (SL) brackets and conventional (CV) brackets. Differences between maxillary and mandibular rates were computed. Materials and Methods: Twenty-five subjects requiring four first premolar extractions were enrolled in this split-mouth, randomized clinical trial. Each patient had one upper canine and one lower canine bonded randomly with SL brackets and the other canines with CV brackets but never on the same side. NiTi retraction springs were used to retract canines (100 g force). Maxillary and mandibular superimpositions, using cephalometric 45° oblique radiographs at the beginning and at the end of canine retraction, were used to calculate the changes and rates during canine retraction. Paired t-tests were used to compare side and jaw effects. Results: The SL and CV brackets did not show differences related to monthly canine movement in the maxilla (0.71 mm and 0.72 mm, respectively) or in the mandible (0.54 mm and 0.60 mm, respectively). Rates of anchorage loss in the maxilla and in the mandible also did not show differences between the SL and CV brackets. Maxillary canines showed greater amount of tooth movement per month than mandibular canines (0.71 mm and 0.57 mm, respectively). Conclusions: SL brackets did not show faster canine retraction compared with CV brackets nor less anchorage loss. The maxillary canines showed a greater rate of tooth movement than the mandibular canines; however, no difference in anchorage loss between the maxillary and mandibular posterior segments during canine retraction was found.

We have developed a new orthodontic bracket with three slots with lubricative properties on the working surfaces and proposed a new orthodontic treatment system employing 0.012−0.014-inch Ni-Ti arch wires. We recruited 54 patients, of which 27 received treatment with the new zirconia bracket with multiple slots system (M group), and the others received treatment with standard edge-wise appliances (control group [C group]). We compared the (1) tooth movement rate at the early stage of leveling; (2) changes in the dental arch morphology before and after leveling; and (3) pain caused by orthodontic treatment. Student’st-test was used in all assessments. The tooth movement rate in the maxillomandibular dentition was higher in the M group. The basal arch width, anterior length, and the intercanine width in the maxillary dentition were not significantly different in the two groups; however, the intercanine width in the mandibular dentition was higher in the C group. In assessments of treatment-related pain, the visual analogue pain score was 56.0 mm and 22.6 mm in the C and M groups, respectively. A new zirconia bracket with multiple slots system provided better outcomes with respect to tooth movement rate, treatment period, and postoperative pain, thus indicating its effectiveness over conventional orthodontic systems.

Background:Early recognition of axial spondyloarthritis (axSpA) patients is difficult for general practitioners within the large amount of chronic low back pain (CLBP) patients1. As a result, several referral strategies have been developed to help physicians identify patients at risk for axSpA. Most referral strategies were developed in secondary care patients with no available data on their impact. The only referral strategy that was developed and validated in primary CLBP patients is the Case Finding Axial Spondyloarthritis (CaFaSpA) strategy, but required an impact analysis before implementation in daily clinical practice2-3.Objectives:The purpose of this study was to assess the impact of using the CaFaSpA referral strategy on patient reported outcome outcomes (PROs) in primary care patients with CLBP at risk for axSpA.Methods:A clustered randomized controlled trial was performed in a primary care setting in the Netherlands. (ClinicalTrials.gov Identifier:NCT01944163). Each cluster contained the general practices from a single primary care practice and their included patients. Clusters were randomized to either the intervention (use of CaFaSpA referral strategy) or the control group (usual care). Primary outcome was disability after 12 months. Secondary outcome was quality of life, pain and fatigue after 12 months. A linear mixed-effects model was used to explore the effects over time according to intention to treat analysis.Results:In total 679 patients were included within 93 GP clusters. Sixty-four percent of our study population were female and mean age was 36 (7.5) years. Overall RMDQ reduced over time both in the intervention and control group (figure 1). The difference in decrease was not statically significant between the groups (p-value 0.81).Figure 1.Estimated mean RMDQ scores over time for the overall intervention and usual care group.EQ-5D increased by 0.03 after 12 months within the intervention group and 0.01 in the control group (not significant) (table 1). The decrease in pain and fatigue did not differ significantly between the intervention and control group.Table 1.Mean change in PROs after 12 months in the intervention and control groupPROsInterventionUsual careBaseline12 monthsp-valueBaseline12 monthsp-valueEQ-5D mean (SD)0.69 (0.26)0.72 (0.27)0.140.72 (0.24)0.73 (0.25)0.53VAS-pain mean (SD)5.03 (2.42)4.68 (2.69)0.074.96 (2.42)4.55 (2.69)0.02VAS-fatigue mean (SD)5.19 (2.50)5.01 (0.21)0.355.23 (2.45)4.86 (2.73)0.04Conclusion:Although the functional disability due to pain reduces over time, there was no positive effect by referring based on the CaFaSPA model.
