“…The use of 0.12% chlorhexidine as a disinfecting agent has been proposed for base plates of removable orthodontic appliances, among other substrates 13 . A previous study suggested that chlorhexidine solutions in different concentrations have no significant influence on the force degradation of elastic chains 14 . However, the comparison of chlorhexidine and peracetic acid effects on force of elastic chains after disinfection remains not assessed.…”

Aim:To evaluate the force decay of orthodontic elastomeric chains after immersion in disinfecting solutions. Methods: One-hundred and fifty segments of elastomeric chains were divided in 3 groups: Control group -no disinfection; Chlorhexidine group -disinfection in 0.12% chlorhexidine digluconate solution; and Peracetic acid group -disinfection in 0.2% peracetic acid solution. Elastomeric chains of 14 mm were stretched up to 20 mm and the given force (kgf) was evaluated in an Instron universal testing machine at the following intervals: 1 h, 1 day, 7, 14, 21 and 28 days after the immersion in the disinfecting solutions. Data (kgf) were analyzed statistically by Analysis of Variance and Tukey's test at a 5% significance level. Results: Both groups presented similar force decay along 7 days and remained stable up to 28 days. Force degradation was observed in the first hours of activation (~50%). Conclusions: It may be concluded that there were no significant differences among the investigated groups, in most interval times, indicating that both chemical solutions can be used for previous disinfection of orthodontic elastomeric chains.

“… 2 , 6 In several studies, including one conducted by Pithon et al, a 24-hour period was chosen since it generally constituted the time for elastic users to replace their elastics, while a 12-hour period represented the median time between initial use and replacement. 14 …”

BackgroundTwo types of orthodontic elastics exist based on their material, latex and nonlatex, each of which has different properties in clinical use. Some of the differences include their initial force and force degradation over time. This study was conducted to compare the force changes in both materials.AimTo evaluate the force degradation of latex and nonlatex elastics under moderate stretching over time.MethodsMedium-force orthodontic latex and nonlatex elastics from American Orthodontics (AO) and Ortho Technology (OT) of lumen size 1/4 inches and 3/16 inches (total sample 110 elastics) were submerged in artificial saliva (pH 6.7) and incubated for 48 hours. Then, the elastic force was measured at the following time intervals: initial, 1, 3, 6, 12, 24, and 48 hours. Orthodontic latex and nonlatex elastics from AO and OT were analyzed using Fourier-Transform Infrared Spectroscopy and energy-dispersive X-ray to know the chemical bond structure and elements.ResultsThere was a statistically significant difference between latex and nonlatex force degradation over a period of 0–24 hours (P<0.05), while no significant difference existed between 24–48 hours (P>0.05). Force degradation of latex elastics was higher than that of nonlatex elastics. Energy-dispersive X-ray results on nonlatex elastic bands from OT and AO showed higher C element in the latex elastic band from OT, while the latex elastic band from AO had higher Al element.ConclusionMedium-force latex and nonlatex elastics 1/4 inches and 3/16 inches in size both showed force degradation at 1, 3, 6, 12, and 24-hour intervals under 30 mm stretching when kept in artificial saliva (pH 6.7) and incubated at 37°C for 48 hours.

“…The present study occurred in a period of 4 weeks, because this is the time interval most frequently observed in orthodontic offices, with regard to consultations 1,21 . The size of elastic chains adopted in this study was the short elastic chain, considering that there are differences in the forces exerted by the segments of long and short chains, when stretched over the same distance, so that the segment of the short chain without space between the links has shown higher values of force over the course of time 14,15 .…”

“…This equipment was used in a previous study by Pithon et al 1 , to evaluate the influence of chlorhexidine on the force released by chain elastics. It should be pointed out that while the measurements were made, the room temperature was maintain constant at 25Cº.…”

ResumoObjetivo: Avaliar os efeitos de diferentes bebidas alcoólicas sobre a força de decaimento de elásticos ortodônticos. Material e método: Em estudo laboratorial, foram testados 7 grupos de amostra, sendo: 1 grupo controle representado pela água destilada, e 6 experimentais: 2-Wisky, 3-Conhaque, 4-Vodka, 5-Cerveja, 6-Cachaça e 7-Vinho. Utilizou-se gabaritos para realizar a submersão das cadeias nas soluções de bebidas alcoólicas durante 30 segundos, uma vez ao dia nos grupos experimentais. A medição de força foi realizada com um dinamômetro digital em seis períodos diferentes 0, 1, 7, 14, 21 e 28 dias. Resultado: Não houve diferenças significativas entre os tratamentos nos momentos baseline, 7 dias, 14 dias e 28 dias. Foram observadas diferenças estatísticas entre o grupo 7 e os demais no momento 24 horas e entre o grupo 1 e os demais no período 21 dias. No período 28 dias não houve diferenças significativas no padrão de força entre todos os grupos (p<0.05) Conclusão: As bebidas alcoolicas não exercem influência na degradação da força dos elásticos em cadeia.Descritores: Ortodontia corretiva; elastômeros; bebidas alcóolicas. AbstractObjective: To evaluate the effects of different alcoholic beverages on the decline in force of orthodontic elastics. Material and method: In a laboratory study, 6 groups of alcoholic beverages were tested. Control group (Group 1) was composed of distilled water. Experimental groups were Whisky (Group 2), Brandy (Group 3), Vodka (Group 4), Beer (Group 5), Sugar Cane Spirit/Rum (Group 6), Wine (Group 7). In the experimental groups, templates were used to enable elastics to be submerged in the alcoholic beverages for 30 seconds once a day. Force was measured with a digital dynamometer in six different time intervals: baseline, 1, 7, 14, 21 and 28 days. Result: There were no significant differences between the treatments in the time intervals: baseline, 7, 14 and 28 days. There were statistical differences between Group 7 and the others in the first 24 hours, and between Group 1 and the others after 21 days. After 28 days, there were no significant differences in the force pattern among all groups (p<0.05). Conclusion: Alcoholic beverages had no influence on the decline in force of the chain elastics.
