“…The type of mouthwash had no significant effect on decreasing the tensile strength of OLE. This finding agrees with a previous study, which stated that mouthwash does not influence the tensile strength reduction of orthodontic intermaxillary elastics [16]. Soaking OLE in mouthwashes three times a day for 60 seconds is not sufficient to reduce its force strength [17].…”

“…In this study, the elastic was immersed in liquids such as artificial saliva and mouthwashes. Microstructural damage can occur due to the filling of the spaces in the latex matrix and cause intermolecular damage to the rubber [16]. Its intermolecular bonds may also be disrupted by the chemicals in the mouthwash acting as potent plasticizers [17].…”

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.

“…27 Several in vitro studies have reported a greater strength loss in latex and non-latex intermaxillary elastics after placing them in the oral cavity. 28 Latex elastics presented superior strength than the non-latex ones. 29 Leão-Filho et al evaluated the in vitro effects of frequently ingested beverages (Coca-Cola, coffee, orange juice, beer, red wine, and AS as the control) on the force degradation in intermaxillary elastics (1/4-inch).…”

“…30 Likewise, in another study performed by Macedo et al, the authors did not find differences between the latex and non-latex elastics exposed to saliva and chlorhexidine solutions. 28 Although the initial force that the chains exert on the teeth is sufficient, the changes occurring after 21 days may render them insufficient. Hence, the clinician needs to educate the patient on scheduling regular appointments.…”

Background. Elastomeric chains promote controlled movements and are widely used in orthodontics.Objectives. The aim of the study was to evaluate the force decay and elongation of orthodontic chains exposed to low-pH saliva (pH = 4) and different beverages common in the diet.Material and methods. Force decay and elongation were determined in vitro at 6 time intervals over 21 days for 2 commercial elastomeric chains -Ormco (group A) and Borgatta (group B). The samples were immersed in artificial saliva (AS) at pH 4, Coca-Cola ® , coffee, or beer for 15 min every day, or in AS (the control group). For the remaining time, the chains were placed into AS at 37°C. In addition, microscopic qualitative changes were recorded by means of scanning electron microscopy (SEM).Results. The group B chains showed higher force decay and elongation at the end of the follow-up as compared to the group A chains. Exposure to beer had a greater impact on the force decay and elongation of the chains as compared to other liquids, but it was not statistically significant. The group A chains showed a more irregular surface than the group B chains, in particular, those exposed to coffee.Conclusions. Elastomeric chains suffer force decay and elongation as a function of time, mainly in the first 24 h. At the end of the follow-up, the group A chains exhibited less force decay in comparison with the group B chains. The qualitative observations showed that the chains in group A had a more irregular surface than the chains in group B.

Background In orthodontic treatment, closing spaces, specifically the extraction and scattered spaces of the anterior teeth, requires some auxiliary bias, such as an elastomeric chain. Many factors affect the mechanical properties of elastic chains. In this study, we investigated the relationship of the filament type, the number of loops, and the force degradation of elastomeric chains under thermal cycling conditions. Methods The orthogonal design included three filament types (i.e., close, medium, and long). Four, five, and six loops of each elastomeric chain were stretched to have an initial force of 250 g in an artificial saliva environment at 37 °C and thermocycling between 5 and 55 °C three times a day. The remaining force of the elastomeric chains was recorded at different time points (4 h, 24 h, 7 days, 14 days, 21 days, and 28 days), and the percentage of the remaining force was calculated. Results The force decreased significantly in the initial 4 h and degraded mostly within the first 24 h. In addition, the percentage of force degradation increased slightly between 1 and 28 days. Conclusions Under the same initial force, the longer the connecting body is, the fewer the number of loops and the greater the force degradation of the elastomeric chain are.
