“…Nano-HAP was synthesized in a wet condition according to the method of Boanini et al, 28 with some modifications. 29 4 OH, was added drop-wise under stirring. The precipitate was maintained in contact with the reaction solution for 5 hours at 90°C under stirring, and then, centrifuged at 1800 g for 10 minutes.…”

Aim: Evaluate in situ the effect of nanohydroxyapatite paste (nano-HAP) before bleaching with hydrogen peroxide 35% (HP35%) by ion chromatography (IC) Knoop hardness number (KHN) and tristimulus colorimetry (TC). Materials and methods:A total of 60 fragments were obtained from third molars included (3 mm × 3 mm × 3 mm) and the specimens were divided into three groups (n = 20): Gas chromatography (CG) (negative control group) = no bleaching; HP35% (positive control group) = HP35% whitening (whiteness HP35%); nano-HAP = application for 10 minutes before bleaching treatment + HP35%. The specimens were fixed to the volunteers' molars. The KHN and TC were measured before and after bleaching. For IC, the dentin layer was removed, leaving the enamel that was crushed, and autoclaved for chemical quantification (calcium, fluorine, and phosphorus). The results of KHN and TC were analyzed statistically by analysis of variance (ANOVA) followed by Tukey test (p < 0.05). Results:The HP35% group showed reduction of the Ca, F, and P ions. The initial and final KHN mean of the CG and nano-HAP did not differ statistically; however, the group of HP35% did differ statistically. The mean ΔE of the HP35% and nano-HAP groups did not differ statistically from each other. However, they differed from the CG. Conclusion:The nano-HAP paste preserved the KHN, promoted the lower loss of Ca and P ions and an increase of F ions when compared with the CG, but did not influence the effectiveness of the bleaching treatment.Clinical significance: Nano-HA is a biomaterial that has shown positive results in the prevention of deleterious effects on the enamel by the action of the office bleaching treatment.

“…Entre sus componentes se encuentran: agua, azúcar, edulcorantes, ácidos (ortofosfórico, cítrico, má-lico, tartárico), cafeína, colorantes, saborizantes, dióxi-do de carbono, conservantes y sodio [8][9][10]. El ácido ortofosfórico es una sustancia altamente corrosiva que tiene la capacidad de disolver sales de calcio, magnesio y sodio, lo que origina desmineralización en el esmalte dental en las personas que ingieren productos que lo contienen [10].…”

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 ...
