“…Such results were also found by Liu, Wataha and Craig (1993) [16]. This difference between studies may be due to differences in methodology, as well as the brand of the elastic studied, since it is known that the manufacturing process of elastics, as well as their compositions influence the degradation of forces (Behnaz et al, 2017) [ [8]].…”

“…Another negative point related to these elastomers is that despite the important role of force transmission, they are still not considered ideal materials as they present a relevant decline in force that may cause a clinical problem, since orthodontic treatments act on the strength of these accessories (Pithon et al, 2014) [ [6]]. This gradual reduction in elastomer strength is linked to activation time, oral environment temperature, patient diet (Pithon et al, 2013)[ [7]] and use of substances for oral hygiene (Pithon et al, 2013;Behnaz et al 2017;Behnaz et al 2018)[ [7], [8], [9]].…”

The objective of this study was to evaluate the color (∆E*) and the degradation of the strength of chain elastics when submitted to different rinses. Forty segments of aesthetics chain elastics (American Orthodontics) were maintained extended in distilled water at 37°C. The elastics (n=10) were immersed twice a day for 60 seconds each in the following solutions: Chlorhexidine Gluconate; Grapefruit essential oil; Ginger and distilled water. The readings were performed in the following times: initial, 24 hours, 7, 14, 21, and 28 days using universal testing machine and spectrophotometer. The force degradation data were analyzed by mixed models for repeated measurements in time, and the data from ∆E* were evaluated by Kruskal Wallis and Dunn and Friedmann and Nemenyi (α=5%). Except for the group immersed in Ginger, there was a significant decrease in force degradation after 24 hours (p0.05); after 7 days there was force recovery for all solutions. For ∆E* it was found that there was no statistically significant difference between the solutions for most of the time. However, after 28 days Chlorhexidine showed less ∆E* than the other solutions. It is concluded that the time in which the elastic chain is stretched influences the degradation of strength; immersions in rinses with the exception of ginger solution degrade the strength after 24 hours and; there is color change for all solutions after 28 days.

“…Several works (ASH and NIKOLAI, 1978;NATTRASS et al, 1998;BEATTIE and MONAGHAN, 2004;TEIXEIRA et al, 2008;LARRABEE et al, 2012;LEÃO FILHO et al, 2013;PITHON et al, 2014;BEHNAZ et al, 2017) studied the influence of environmental factors (the environment in which the materials are found) on force degradation in different types of elastic materials in vitro, however, none of the studies found verified the action of fruits originating from the Amazon, which are currently widely consumed throughout the world. Regarding orthodontic chain elastics, no force degradation studies were found for the Ortho Classic elastic, recently developed by the industry, which, according to the manufacturer, has the advantage of being interchangeable after a longer period of use.…”

The aim was to evaluate the color changes (ΔE*) and force degradation (FD) of esthetic elastic ligatures when submitted to foods from the Amazonian diet. 150 segments of elastics (n=10) (American Orthodontics -AO Orthoclassic -OC and Orthometric -OM) were divided to be submitted 2 times a day, for 1min each immersion, for 28 days, in one of the solutions: AI-açaí, CU-cupuaçu, TU-tucumã, RW-red wine and DW-distilled water (control). FD was evaluated using a universal testing machine and ΔE* by spectrophotometer. Qualitative analyses were performed by scanning electron microscopy (SEM). The readings were taken at the following times: T0 -initial, T1 -24 hours, T2 -14 and T3 -28 days. The FD and ΔE* data were analyzed by non-parametric statistics (p<0.05). It was found that in the 3 brands, in all substances, there was a significant decrease in strength at T1 and at T2 there was an increase in strength. At T3, it is found that CU and DW promote significant differences from AI to OM and OC. For ΔE* it was verified after 28 days in OM the ΔE* was higher for the elastics submitted to TU and RW than in CU and DW. For OC, the variation was greater in DW than for TU and AI, whereas for AO there was no significant difference between the groups. for all brands there is a higher FD in the first 24 hours, with elastic recovery after this period; all solutions promote FD in the evaluated elastics and, for all brands tested, the ΔE* is clinically unacceptable after 28 days of immersion.

“…The numbers of links used to measure the strength of the elastomeric chains were quite different. Behnaz et al 17 used elastomeric chains with 6 links. Authors such as Sadeghian et al 14 , Javanmardi and Salehi 4 , Odmikhoda et al 16 and Pithon et al 7,15 used 5 links to carry out measurements, two of which placed pins in the ends, leaving 3 links in the central part.…”

“…Of the mouthwashes and agents used in the studies included in this review, the most frequently studied was Listerine® (26.9% alcohol) 11,12,13,14,15,19 . Some authors studied other types of Listerine®brand mouthwashes, such as Listerine® Zero (0% alcohol) 15 , Listerine® Total Care Zero (NaF 0.02%) 17 , Listerine® Healthy White (NaF 0.02% + hydrogen peroxide) 17 , Listerine® Whitening (hydrogen peroxide) 15 and Listerine® Green Tea 20 . Rinses containing 0.2% chlorhexidine, such as Chlorhexidine Plus® 11 , Cordosyl® 18 and Cleanform®, and 0.12% chlorhexidine, such as Periogard®, were also studied.…”

Introduction: Orthodontic elastomeric chains are used in many orthodontic treatments. However, their activation or the action of external factors such as the daily use of mouthwashes can contribute to the increase of force decay causing a loss of effectiveness. The objective of this systematic review and a meta-analysis was to analyse the influence of the most widely used mouthwashes and their mainly components on the force decay of the orthodontic elastomeric chains.Material and Methods: A systematic search of the literature was performed in the electronic databases of PubMed, Cochrane Library (CENTRAL), Scopus, EMBASE and Web of Science, as well as grey literature (Opengrey). No limit was placed on publication year and research was done up to June 2021. Controlled clinical trials, randomized clinical trials (RCTs), cohort studies, case–control studies, cross-sectional studies, multicentre studies, and in vitro studies were there was an exposure of orthodontic elastomeric chains to certain mouthwashes and their main components were included. For the quantitative analysis, studies were analysed with a mixed-effect (random effect) meta-regresion model, with beta coefficients and R2 values. I2 index and Q and Egger tests were used to find heterogeneity among studies. Results: 14 articles met the inclusion criteria and were selected for qualitative analysis. The same 14 articles were selected for the quantitative synthesis (meta-analysis). The results of the meta-analysis showed that, in general, all the mouthwashes were associated with a greater force decay than the control agents at 24 hours, at 7, 14, 21 and at 28 days. When comparing the different mouthwashes, the results showed that at 7 days (p=0.005) significant differences were found in the force decay among them. Mouthwashes containing alcohol had a significantly higher percentage of degradation than those containing chlorhexidine 0.2%, sodium fluoride (NaF) or Persica. On the contrary, in the measurements performed at 24 hours (p=0.200), 14 days (p=0.076), 21 days (p=0.120) and 28 days (p=0.778) no differences in the strength among the different mouthwashes were found.Conclusion: In general, mouthwashes tend to increase the speed of force decay and have a negative impact in the physical properties of orthodontic elastomeric chains, resulting in a loss of effectiveness. For mouthwashes such as Listerine® and those containing alcohol this difference can be higher than for mouthwashes containing chlorhexidine, NaF or bleaching agents.
