“…Moreover, orthodontic equipment diminishes the impact of brushing on plaque and salivary flow. During orthodontic attachment bonding, increased amounts of Streptococcus mutans and lactobacilli are identified in the oral cavity [2]. Nowadays, synthetic elastic modules (often referred to as plastic modules) are used in numerous fields of orthodontics [3].…”

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..

“…The initial adhesion of bacteria to an orthodontic retainer is the critical factor in forming pathological biofilms [ 18 , 19 ]. These biofilms are hard to entirely remove with a toothbrush and are the leading cause of dental caries and periodontal diseases [ 20 ]. Thus, it is essential to prevent the adhesion of pathological biofilms before it occurs.…”

This study aimed to fabricate nano-hydroxyapatite (nHA) grafted/non-grafted E-glass-fiber-based (nHA/EG) and E-glass fiber (EG) orthodontic retainers and to compare their properties with commercially available retainers. Stainless-steel (SS) retainers and everStick Ortho (EST) were used as control groups. The retainers were evaluated with Raman spectroscopy and bonded to bovine teeth. The samples were fatigued under cyclic loading (120,000 cycles) followed by static load testing. The failure behavior was evaluated under an optical microscope and scanning electron microscope. The strain growth on the orthodontic retainers was assessed (48h and 168h) by an adhesion test using Staphylococcus aureus and Candida albicans. The characteristic peaks of resin and glass fibers were observed, and the debonding force results showed a significant difference among all of the groups. SS retainers showed the highest bonding force, whereas nHA/EG retainers showed a non-significant difference from EG and EST retainers. SS retainers’ failure mode occurred mainly at the retainer–composite interface, while breakage occurred in glass-fiber-based retainers. The strains’ adhesion to EST and EG was reduced with time. However, it was increased with nHA/EG. Fabrication of nHA/EG retainers was successfully achieved and showed better debonding force compared to other glass-fiber-based groups, whereas non-linear behavior was observed for the strains’ adhesion.

“…21 It has been found that the proportion of anaerobic bacteria responsible for the generation of sulphurcontaining compounds increases in the gingival sulcus of patients undergoing orthodontic treatment using fixed or removable appliances. [21][22][23][24] There are relatively few studies that have explored the relationship between halitosis and orthodontic treatment either with fixed or removable appliances. Using organoleptic and OralChroma tests, Costacurta et al observed that children with fixed orthodontic appliances had higher levels of volatile sulphur-containing compounds, specifically, a higher level of H2S than children with removable devices and children without orthodontic treatment.…”

Halitosis is a common condition disturbing a significant number of people worldwide. 1,2 Overall, the occurrence of this problem is high and has a substantial impact on the quality of life of the affected individuals. In addition, patients suffering from halitosis may display avoidance behaviours due to social insecurities and fear of rejection. [3][4][5] The aetiology of halitosis is complex involving several oral and medical conditions. However, in the majority of cases, the oral cavity is responsible for the mouth malodour. Halitosis originating from the mouth is usually the result of microbial metabolism of the plaque biofilm. Bacterial niches such as the tongue surface,
