“…However, comparatively few studies have investigated the effects of bonding materials used in brackets on enamel color (3,5,(8)(9)(10) and only 2 clinical studies examined the color alterations of teeth associated with FOT (3,4). According to the findings of those studies, visible enamel color changes may occur with fixed appliances, which would be detected in clinical trials (3,4). Although enamel color was changed after orthodontic treatment, the lightcured composite was associated with lower discoloration rates than chemically cured resins (4).…”

“…Orthodontists or patients may encounter unwanted changes on the enamel surface or structure, such as discoloration, white spots, microcracks, fractures, and abrasions during and after fixed orthodontic treatment (FOT) because of, e.g., diet, oral care, bonding materials and techniques, composites, appliances, debonding, and clean-up procedures (1)(2)(3). Bonding materials and composites of FOT are the most prominent factors responsible for enamel color alterations (3,4). Enamel discolorations may occur by direct absorption of food colorants and products arising from the corrosion of the orthodontic appliance into resin tags (5,6).…”

IntroductionOrthodontics is a unique science in dentistry since its workspace sets on the external surface of enamel when using fixed appliances for treatment. Orthodontists or patients may encounter unwanted changes on the enamel surface or structure, such as discoloration, white spots, microcracks, fractures, and abrasions during and after fixed orthodontic treatment (FOT) because of, e.g., diet, oral care, bonding materials and techniques, composites, appliances, debonding, and clean-up procedures (1-3). Bonding materials and composites of FOT are the most prominent factors responsible for enamel color alterations (3,4). Enamel discolorations may occur by direct absorption of food colorants and products arising from the corrosion of the orthodontic appliance into resin tags (5,6). The long-term presence of these residues in the enamel tags during fixed treatment makes the color stability of these materials critical for tooth color (7).A great deal of orthodontic research has concentrated on the assessment of the physical and mechanical performances of the adhesive resins. However, comparatively few studies have investigated the effects of bonding materials used in brackets on enamel color (3,5,8-10) and only 2 clinical studies examined the color alterations of teeth associated with FOT (3,4). According to the findings of those studies, visible enamel color changes may occur with fixed appliances, which would be detected in clinical trials (3,4). Although enamel color was changed after orthodontic treatment, the lightcured composite was associated with lower discoloration rates than chemically cured resins (4). According to Karamouzos et al. (4), orthodontists may choose the use of no-mix and light-cured composites, whose effects on enamel color were the same. However, a recent in vitro study about discoloration of these types of orthodontic composites revealed that unsatisfactory color stability was Background/aim: To determine the color alterations of natural teeth associated with different orthodontic composites used in comprehensive short-term treatment.Materials and methods: Twenty-two patients were treated with fixed appliances and 22 untreated subjects were also evaluated. Lower incisors were bonded with different orthodontic composites: 42 with Grengloo, 41 with Light Bond, 31 with Kurasper F, and 32 with Transbond XT. The color parameters of the Commission Internationale de l'Eclairage (CIE) were measured for each tooth with a spectrophotometer. Color assessment in relation to time, adhesive material, and their interaction was made with 2-way mixed analysis of variance (ANOVA) and 1-way ANOVA for the color differences (∆E*). Further analyses were done using Tukey's honestly significant difference tests and paired-samples t-tests. Results:The color of teeth was affected by treatment. The mean L* and a* values increased, whereas the mean b* values decreased. Total color differences of teeth demonstrated visible color changes clinically after treatment, ranging from 1.12 to 3.34 ∆E units. However, there w...

“…Autores como [23], que encontraron cambios del color dental de 2,85 unidades ΔE en promedio, después de tratamientos de ortodoncia, sugieren la necesidad de más investigaciones para analizar el color dental durante la fase de retención, ya que los residuos de adhesivo permanecen en el esmalte, haciéndolo susceptible a mayores cambios en el color.…”

Rev Nac Odontol. 2014;10(18):49-56. doi: http://dx.doi.org/10.16925/od.v10i18.721 Resumen. Introducción: esta investigación pertenece a la línea de investigación "Terapéuticas y biomecánicas en ortodoncia y ortopedia" realizada en el 2013 por el grupo ODONTOPOSTGRADOSUCC de la Facultad de Odontología, sede Bogotá. El objetivo fue evaluar las alteraciones del color dental con tres bebidas oscuras, en dientes tratados con ortodoncia fija. Métodos: estudio experimental in-vitro, con 48 premolares humanos, aleatorizados en tres grupos de 16 dientes. Después de la cementación y descementación de brackets, los dientes fueron sumergidos durante 10 días a 37°C, en Coca-cola ® , vino tinto y café. El color fue medido antes de la cementación de brackets (T1) y después de la exposición a las sustancias (T2), con un espectrofotómetro (Vita Easyshade ® ). La diferencia en color (ΔΕ) fue calculada entre T1 y T2. Se aplicó la prueba t pareada y Bonferroni para determinar el significado de las diferencias en los parámetros L, C, h (p < 0,05). Resultados: se encontró una diferencia significativa en L, C, h (p = 0,05); los cambios de color fueron significativos: entre 79,8 (Coca-cola ® ) y 7,5 (café) unidades ΔΕ. Conclusiones: los dientes presentaron cambios en el color del esmalte grabado al someterse a bebidas oscuras, presentando mayor diferencia con Coca-cola ® y menor con café.Palabras clave: esmalte dental, decoloración dental, espectrofotometría, agentes colorantes. The effect of discoloration solutions on the color of teeth treated with fixed orthodontics: An in vitro studyAbstract. Introduction: this research was conducted in 2013 by the ODONTOPOSTGRADOSUCC group at the Faculty of Dentistry, Bogotá campus, and belongs to the "Therapeutics and biomechanics in orthodontics and orthopedics" line of research. The aim of the research was to evaluate changes in tooth color with three dark beverages, for teeth treated with fixed orthodontics. Methods: in this in-vitro experimental study, 48 human premolars were randomly split into three groups of 16 teeth. After cementing and then de-cementing braces, the teeth were submerged in Coca-Cola ® , red wine and coffee for 10 days at 37°C. Color was measured before cementing braces (T1) and after exposure to the substances (T2) with a spectrophotometer (Vita Easyshade ® ), to calculate the difference in color (Δe) between T1 and T2. Paired and Bonferroni t-tests were applied to determine the significance of difference in the parameters L, C, h (p < 0.05). Results: a significant difference was found in L, C, h (p = 0.05). Changes in color were significant: between 79.8 (Coca-Cola ® ) and 7.5 (coffee) ΔΕ units. Conclusions: teeth presented changes in the color of etched enamel when subjected to dark beverages, with the greatest differences occurring with ...
