“…This was seen in the control media (artificial saliva), Sensodyne, and Listerine mouthwashes. This was in accordance with the finding of several studies of elastomeric products Singh et al [33] Leao Filho et al [34] The other result of force decay demonstrated also a sudden drop as in Chlorhexidine mouthwashes. This pattern was previously mentioned by Evangelista et al [35] and Santos et al [36].…”

Background: In several orthodontic treatments, elastomeric chains are utilised to produce force, however, this force degrades over time, which may impact tooth mobility. This study aims to investigate how different mouthwashes (Chlorhexidine 0.2%, Sensodyne, and Listerine) may affect the force degradation of two different types of elastic ligatures (Ortho Matrix and 3M Unitek) through the amount of force remaining. Materials and methods: Two control groups and six experimental groups each included 600 pieces of the elastomeric chains Ortho matrix (OM) and 3M Unitek (3M). Pieces were stretched to a 25mm thickness, placed on pins set into an acrylic block, and kept at 37°C in artificial saliva. For the duration of the study, each of the test groups spent one minute immersed in one of three distinct kinds of mouthwash. Ten continuous thermocyclers with temperatures ranging from 5 to 55 degrees Celsius were performed each day, alternating between cold and hot water baths. While calculating the forces, we considered six different time intervals: the beginning, 24 hours, 1, 2, 4, and 6 weeks. The one-way analysis of variance (ANOVA) test and the t-test were used to compare the mean force of a number of different mouthwashes, elastomeric chains, and times. A value of 0.05 was chosen as the cutoff for statistical significance. Results: Over time, both types of elastomeric chains significantly lost force at 6 weeks (p<0.05). At all times, the 3M Unitek (3M) created more force than the Ortho matrix (OM) elastomeric chain. Compared to other mouthwashes, chlorhexidine mouthwash had a substantially less impact on force degradation, with discernible very simple change when compared to control groups (Artificial saliva). Conclusion: According to findings, the 3M Unitek offered a higher force level than the other sort of elastomeric chains, and there is a difference that is clinically significant between the two types of elastomeric chains. It is possible that the pH of the mouthwashes, as opposed to other substances, contributes to the gradual loss of power over time. Mouthwashes containing chlorhexidine had the third-smallest influence on the force degradation of elastomeric chains, after Sensodyne and Listerine..

“…However, the combination of these environmental impacts, different salivary pH baseline, beverages with low pH, and cyclic stretching at the same time may enhance the force degradation significantly which needs to be evaluated in the future. In the study by Leão Filho et al .,[17] they did not report significant differences in the force decay of the interarch elastics immersed in different beverages. The duration of the investigation was almost 15 min and the intermaxillary elastic acted the same in exposure to the tested beverages.…”

“…[17] After the plateau phase of force decay between 8 and 24 h, even intraoral water can plasticize cross-linked polymers including latex rubber,[1920] which leads to the reduction in the creep compliance during the experiment that may lead to the reduction of flexibility and an increase in the force for a few hours from 24 to 36 h. The fluctuation of pH had a considerable effect on this matter.…”

Background:Latex elastics are still in common use due to their low cost and high flexibility to improve sagittal discrepancies or interdigitation of teeth. Mechanical properties of elastics are influenced by several environmental factors such as pH changes. This study evaluated similar latex elastics to define the influence of synergic effect of intermittent low pH and various baselines pH of saliva.Materials and Methods:Four groups of latex elastics (3-M Unitek, 3/16 inch) were tested (n = 15 in each group). Two groups of elastics were immersed in two tanks of artificial saliva with different pH levels of 7 and 5, and two groups were immersed in two tanks of artificial saliva with intermittent drop of pH to 4. The force was measured when the elastics were stretched to 25 mm. These measurements were taken in 0, 4, 8, 12, 24, 36, and 48 h for each group. Repeated measures analysis of variance (RMANOVA) and post-hoc Tukey's test were used to assess the findings. The level of significance was 0.05%.Results:The interaction between pH and time analyzed with RMANOVA showed no significant differences (P > 0.05) except in 36 h (P = 0.014). The Tukey's analysis showed that each comparison between any two groups did not indicate significant differences (P > 0.05) except between Groups 1 and 3 and between Groups 2 and 3 (P < 0.05).Conclusion:No significant correlation was seen between fluctuation of pH and force degradation in latex elastic band except in 36 h.

This analysis was conducted to assess the impact of Coca-Cola on orthodontic materials compared to that of other fluids. Electronical searches were carried out in PubMed, Livivo, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov, supplemented by manual searches in the reference lists of the articles selected for full text evaluation. The risk of bias was assessed on the basis of a "risk of bias summary." A total of 216 bibliographic summaries of articles were obtained, eleven of which were relevant. Nine of these papers showed a low risk, while two publications from one in vivo study exhibited a high risk of bias. The continuing influence of Coca-Cola caused significant discoloration of elastomeric materials and resulted in significantly lower shear bond strength of the brackets and higher corrosion. With regard to orthodontic appliances, additional in situ and in vivo studies are desirable. Special attention should be paid to an appropriate number of samples or patients, as most investigations lacked a sufficient number of test subjects. In addition, investigations with long observation periods and documented beverage consumption should be preferred. The intake of cola-containing beverages during orthodontic therapy and the exposure duration of these beverages to orthodontic material should be reduced to a minimum, as this can impair the adhesive strength and lead to corrosion of orthodontic brackets. The interval between orthodontic appointments should be short to avoid discoloration of orthodontic elastomeric ligatures.
