“…Similar results were observed by Alzahawi [23] who compared root resorption after the leveling phase of treatment, performed by either superelastic NiTi or conventional multi-stranded stainless steel archwires using conventional radiography. He hypothesized that the inactive intervals at force application, which may prolong treatment time, allow for the repair of resorption lacunae.…”

OBJECTIVES:The aim of the study was to clinically evaluate and compare 0.016-inch superelastic nickel-titanium (NiTi) and 0.016-inch heat-activated nickel-titanium (NiTi) archwires in terms of alignment efficiency, root resorption, and pain intensity. METHOD:A total of 20 patients requiring fixed orthodontic treatment, having Little's irregularity index of 5-8, and requiring first premolar extractions were recruited. They were randomly allocated to receive two different archwires (0.016-inch superelastic NiTi or 0.016-inch thermoelastic NiTi). Good-quality impressions were taken of the lower arch before archwire placement (T0) and at every month after that till the alignment was complete. The rate of tooth alignment was measured on casts by determining Little's irregularity index. The pain experienced by the patient was assessed 24 hours and 1 week after the placement of the archwire on a visual analogue scale. Cone beam computed tomographic radiographs of lower anterior teeth were taken before and after alignment to assess root resorption. Data obtained were subjected to statistical analysis using the SPSS software (version 20.0). The level of significance was kept at 5%. RESULTS:The repeated measures ANOVA indicated that there was no significant difference in the aligning efficiency of superelastic and heat-activated NiTi wires. (p = 0.45). The Mann Whitney U test showed that superelastic NiTi wires had statistically significant higher VAS scores than heat-activated NiTi at 24 hours and 1-week interval (p < 0.05). Student's t-test indicated greater root resorption with superelastic NiTi but the difference was not statistically significant. CONCLUSION:Both the wires showed similar aligning efficiency and resulting root resorption. Superelastic NiTi was observed to produce more pain compared to heat-activated NiTi in the aligning phase.

“…RR is a physiological or pathological process that involves breakdown of root structure, specifically mineralized cementum and dentin and nonmineralized dentin. 2,4,5 Physiological RR occurs naturally and is responsible for the RR of deciduous teeth, whereas pathological RR is usually inflammatory in nature.…”

Objective: To investigate the effect of low-frequency mechanical vibration (LFMV) on orthodontically induced root resorption. Materials and Methods: Forty male CD1, 12-week-old mice were used for the study. The mice were randomly divided into five groups: group 1 (baseline)-no spring and no mechanical vibration, group 2-orthodontic spring but no vibration, group 3-orthodontic spring and 5 Hz of vibration applied to the maxillary first molar, group 4-orthodontic spring and 10 Hz of vibration applied to maxillary first molar, and group 5-orthodontic spring and 20 Hz of vibration applied to maxillary first molar. In the different experimental groups, the first molar was moved mesially for 2 weeks using a nickel-titanium coil spring delivering 10 g of force. LFMVs were applied at 5 Hz, 10 Hz, and 20 Hz. Microfocus X-ray computed tomography imaging was used to analyze root resorption. Additionally, to understand the mechanism, we applied LFMV to MC3T3 cells, and gene expression analyses were done for receptor activator of nuclear factor kappa-B ligand (RANKL) and osteoprotegerin (OPG). Results: Orthodontic tooth movement leads to decreased root volume (increased root resorption craters). Our in vivo experiments showed a trend toward increase in root volume with different frequencies of mechanical vibration. In vitro gene expression analyses showed that with 20 Hz of mechanical vibration, there was a significant decrease in RANKL and a significant increase in OPG expression. Conclusion: There was a trend toward decreased root resorption with different LFMVs (5 Hz, 10 Hz, and 20 Hz); however, it was not more statistically significant than the orthodontic-springonly group.

“…Orthodontic treatment aims to move teeth to their desired positions, but this movement can result in some undesirable consequences, such as root resorption [31]. Root resorption occurs when the cells responsible for breaking down and rebuilding bone, known as osteoclasts and osteoblasts, respectively, become overactive and remove more tooth structure than necessary, leading to shorter roots [32][33][34][35]. Intrusion, retraction, and torque movements are common orthodontic tooth movements that have been investigated regarding their potential to cause root resorption [36][37][38][39][40].…”

A variety of metals and alloys are employed in the field of orthodontics, of which the construction of wires happens to be predominant. Through this systematic review, our primary goal was to review and assess studies focusing on complications that emerged during or directly after the completion of an orthodontic treatment plan. We then used a meta-analysis to determine how these complications affected the patients who were receiving orthodontic treatment. A total of 634 documents were discovered after a thorough search of online journals, and 416 of the papers were initially selected. In the end, 14 papers, including in vitro experiments, literature reviews, comparative analyses, observational studies, and retrospective studies, were chosen that met the requisite inclusion and exclusion criteria. There were difficulties related to orthodontic treatment in all of the studies listed in our systematic review, but their severity varied greatly. The effects of gingival mucosa and root resorption were two of the most often mentioned periodontal problems in this review. More long-term studies are required to confirm the involvement of an orthodontic component in these issues, but the majority of the complications were assessed to initially arise after the treatment plan had begun and to resolve with time.
