“…Several authors (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16) showed that the tested elastomeric chains were incapable of generating continuous force over time. According to their research, the greatest amount of force degradation (20 50% depending on the study and chain type) happened on day one (particularly the first hour), followed by a considerably slower rate of degradation over the next four weeks, providing an average degradation of 50 to 85% (5,7,(9)(10)(11)(12)(13)(14)(15)(16) . Andreasen and Bishara (4) advocated additional chain extension to produce a higher initial force to compensate for this rapid force degradation.…”

Background: Elastomeric chains are used to generate force in many orthodontic procedures, but this force decays over time, which could affect tooth movement. This study aimed to study the force degradation of elastomeric chains. Data and Sources: An electronic search on Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, LILACS, and PubMed was made, only articles written in English were included, up to January 2022.Study selection: Fifty original articles, systematic reviews, and RCTs were selected. Conclusion: Tooth movement, salivary enzymes, alcohol-containing mouthwash, whitening mouthwash, and alkaline and strong acidic (pH <5.4) solutions all have a significant impact on elastomeric chain force degradation. The force level of elastomeric chains degrades rapidly over time; however, the force degradation rate is slower in thermoset chains than in thermoplastic ones. An efficient tooth movement could be achieved by using a thermoset chain type with monthly replacement. Ethylene oxide and gamma sterilization methods are preferred to avoid the risk of cytotoxicity.

“…Ramazanzadeh et al [28] investigated the effects of sodium fluoride mouth rinse on the elastic characteristics of several elastomeric chains and determined that daily usage of sodium fluoride mouth rinse had no influence on the force degradation required to attain orthodontic pressures. Another studies found that the use of 0.2% chlorhexidine, 0.2% persica, 0.2% sodium fluoride, and 0.2% chlorhexidine and sodium fluoride mouthwashes had no negative effect on the force degradation of elastomeric chains [29], [30].…”

With the surge of COVID-19 pandemic, orthodontists have recommended the use of mouthwashes. However, this product frequently contains ingredients that can modify the mouth's pH and elastic force. This study examined the influence of mouthwashes on latex elastic force deterioration. One hundred orthodontic latex elastics (1/4”) were separated into five groups: control, zinc sulfate 0.2%, chlorhexidine 0.2%, sodium fluoride 0.2%, and povidone–iodine 1%. The samples were stretched to 19.05 mm, stored in artificial saliva solutions, and incubated. Groups 2–5 tested mouthwashes for 60 seconds every 12 hours and then reverted to artificial saliva. Force was measured using a five-times-activated tension gauge. Elastic force was tested at five-time intervals: baseline, 1, 6, 12 and 24 hours. The statistical analysis included two-way ANOVA and the Tukey post–hoc test. Results showed statistical differences for the time intervals and force degradation of orthodontic latex elastics (p<0.05). The majority of force loss occurred within six hours of extension and immersion. Mouthwashes had no influence on the reduction in elastic force (p>0.05). The force degradation of orthodontic latex elastics was unaffected by mouthwashes. The lowest force degradation was generated by povidone–iodine, followed by zinc sulfate, sodium fluoride, and chlorhexidine.

“…Fewer data are available in the literature about their effect on elastic chains used during fixed bracket treatment. Mouthwashes were proved to be able to change the pH of the oral cavity due to their chemical composition, and thereby influence orthodontic appliances and devices [ 42 ]. It was shown that ethanol attaches to polyurethane polymers, therefore a power chain coming into contact with alcohol-containing mouthwash suffers a greater force degradation than those coming into contact with only saliva or alcohol-free mouthwashes [ 25 ].…”

The Effect of Extrinsic Factors on the Mechanical Behavior and Structure of Elastic Dental Ligatures and Chains

Force provided by elastomers used in orthodontics can be affected by several factors present in the oral cavity. The aim of our study was to investigate the role of mouthwashes, toothbrushing, and smoking in the force decay of such elastomers. Tensile strength, changes in the force continuously exerted, and force decay of elastic chains (Ortho Organizer and Masel Short Power Chain) and elastic ligatures (Dentaurum and Masel) by two separate manufacturers were measured. Measurements were initially made on untreated elastics, followed by exposure to different environmental factors including cigarette smoke, toothbrushing (mechanical plaque control), and two different mouthwashes (chemical plaque control). Changes on the surface of the elastics were studied with scanning electron microscopy (SEM). Untreated Masel elastic ligature showed lower tensile strength than Dentaurum elastic ligature (2339 cN vs. 3660 cN), while significantly higher tensile strength was measured for Ortho Organizer elastic chains than Masel chains (2639 cN vs. 1324 cN). The decrease in the elastic force of Masel ligature was greater in response to all external factors compared to Dentaurum. Although brushing with toothpaste and toothbrush impacted the force of both Masel and Ortho organizer ligatures negatively, force degradation was more apparent in the case of the Ortho organizer. Surface changes were more visible when applying Curasept mouthrinse, however force decay was higher in the Corsodyl group. Mechanical and chemical plaque control can influence the tensile strength and force decay of orthodontic elastomers, which should be considered by selecting the elastomers or determining their changing interval for the practice.
