“…A color change above the threshold (ie, DE 5 3.7) observed in 56% of the control specimens confirms the efficacy of this method. As explained previously, 14,15,21 the lack of saliva, the food coloring, and the inability to simulate the mechanic abrasion caused by brushing are the limitations of this methodology. In the present study, the magnitude of color change was greater during orthodontic treatment than after treatment, with the latter being below the threshold.…”

Objective: To investigate the color alterations in enamel following the use of different orthodontic bonding resins and adhesive residue-removal burs. Materials and Methods: Metal brackets were bonded to extracted human premolars (n 5 175) by using an etch-and-rinse adhesive system, a self-etch adhesive system (SEP), or a resin-modified glass ionomer cement (RMGIC). After 24 hours of photoaging, the brackets were removed and the adhesive residue on the tooth surfaces was cleaned with either a tungsten carbide bur or a Stainbuster bur. Tooth colors were measured with a spectrophotometer at baseline, after adhesive removal, and after additional photoaging. Color evaluation was made, and color differences induced by photoaging were calculated. Statistical evaluation was made using the Kruskal-Wallis test and the Mann-Whitney U-test, with Bonferroni correction. Results: All specimens showed discoloration at varying levels. The highest color change was observed in the etch-and-rinse adhesive/tungsten carbide bur group. When the etch-and-rinse and self-etch adhesives were used, adhesive-remnant removal with Stainbuster burs resulted in significantly lower discoloration. The type of bur did not affect the extent of enamel discoloration in the RMGIC group. Conclusions: Orthodontic treatment alters the original color of enamel, and both the adhesive system and the resin-removal methods are responsible for this change. When brackets are bonded with the etch-and-rinse system or the SEP, cleaning the adhesive residuals with Stainbuster burs is recommended for minimal change. RMGIC can be safely cleaned with tungsten carbide burs. (Angle Orthod. 2014;84:634-641.)

“…Debido a que no existe una estandarización o protocolo de exposición de las muestras en las bebidas pigmentantes, pues se encuentran en la literatura científica estudios con tiempos de exposición de 1 hora [25] hasta de 4 semanas [29], se decidió exponer los dientes a 10 días consecutivos, equivalentes a la suma de tiempos en que una persona con un alto consumo de bebidas oscuras (Coca-cola ® , vino tinto y café) expone sus dientes a estas sustancias durante un año.…”

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 ...

Background and aims:After bracket debonding a correct removal of the adhesive from tooth surfaces without causing any iatrogenic damage to the enamel is needed. However, conventional techniques do not allow a selective removal process. The present article focuses on the removal of adhesive on teeth after bracket debonding by using laser radiation at 355 nm (third harmonic wavelength of a Q-switched Nd:YAG). Material and methods: Brackets were bonded to 10 extracted human premolars from young patients and removed after a storage period of 2 months. As real-time diagnostic technique, laserinduced breakdown spectroscopy (LIBS) elemental analysis was applied for precisely controlling the removal of the adhesive and morphological analysis of the etched surfaces was carried out by scanning electron microscopy (SEM). Results: LIBS technique allowed an on-line precise control in the adhesive removal process. SEM analysis revealed the capability of the 355 nm UV laser radiation to complete the removal of the adhesive on the tooth with no signs of damage on the enamel. Conclusions: Laser ablation process at 355 nm monitored by the LIBS technique allows to carry out efficient removal of the adhesive on teeth.
