“…Rotstein y colaboradores (1991) estudiaron la técnica termocatalítica en perros y encontraron que el 18% de piezas tratadas presentaron signos de reabsorción cervical externa; concluyeron que el peróxido de hidrógeno al 30% asociado al calor aumenta la liberación de radicales tóxicos e irritantes. [43][44][45][46] Harrington y Naktin en 1979 concluyeron "La infiltración de superoxol a través de los túbulos dentinarios pueden iniciar una reabsorción inflamatoria en el área cervical externa". Por otro parte, Lado y colaboradores sugieren que el calor y el superoxol como las causas más importantes de reabsorción externa.…”

RESUMENLa decoloración de los dientes surge por varias causas que se diferencian en la apariencia, la severidad y los tipos de tratamientos. Algunos autores han reportado que, en la mayoría de los casos los dientes no vitales blanquean más rápidamente que los dientes vitales, lo que depende del tiempo de permanencia de la decoloración, es decir, se van observar mejores resultados en decoloraciones recientes que antiguas, donde muy posiblemente no se observarán resultados totalmente satisfactorios, para llegar posteriormente a una recidiva. El propósito de esta revisión es exponer varios cuestionamientos al tener en cuenta las diferentes técnicas y materiales utilizados durante el blanqueamiento de dientes no vitales.

INTRACORONARy NON VITAL TOOTH BLEACHING: A REVIEW ABSTRACTThe discoloration of teeth arises from various causes, which differ in appearance, severity and types of treatments. Some authors have reported that, in most cases non-vital teeth whitening is faster than vital teeth, which will depend on the time of permanence of the discoloration. In other words, there will be better results in recent discolorations than on older ones, where most likely will not observe entirely successful, arriving lately into a relapse. The purpose of this paper is to present several questions taking into account different techniques and materials used during the non-vital teeth bleaching.Key words: Tooth bleaching, Non vital tooth, Hydrogen peroxide.Recibido para publicación: 9 de diciembre de 2011.

INTRODUCCIóNLa estética ha llegado a ser muy importante en la sociedad moderna.1 La odontología estética prevalece aún más debido a un incremento en los pacientes que solicitan este tipo de tratamiento. La gente asocia dientes blancos a conceptos como salud, juventud y vigor. 2Una de las prácticas más comunes en odontología estética es el blanqueamiento, el cual se realiza mediante el uso de sustancias químicas.3 El blanqueamiento de dientes no vitales es un tratamiento estético conservador para dientes pigmentados tratados endodónticamente y ofrece algunas ventajas al ser efectivo, relativamente económico, simple y menos invasivo que el restaurativo.1,4 Sin embargo, los resultados de la terapia de blanqueamiento no son predecibles y hay posibilidad de recidiva de los cambios de coloración.El propósito de esta revisión es exponer varios cuestionamientos al tener en cuenta las diferentes téc-nicas y materiales utilizados durante el blanqueamiento de dientes no vitales. Causas de pigmentación de dientes no vitalesEsencialmente el color del diente está determinado por el color de la dentina y por coloraciones intrín-secas y extrínsecas. El color intrínseco está determinado por las propiedades ópticas del esmalte y la dentina y su interacción con la luz. La coloración extrínsec...

“…There was 1a 1b complication (4)(5)(6). For the same reason, 30% H2O2 should not be used for the walking bleach technique.…”

“…Because H2O2 can diffuse through dentinal tubules as far as the cervical periodontal ligament, altering these structures and generating inflammatory root resorption (7,8). It has been proved that formation using either 30% H2O2 alone or in combination with sodium perborate are more toxic for periodontal ligament cells as compared to a perborate-water suspension, presumed that application of bleaching agents led to denaturation of dentine in the cervical region of tooth (6,8,9). Patients who had bleaching therapy at a young age often have external resorption.…”

Discoloration of teeth, especially the anteriors, can result in considerably cosmetic impairment in young children. It is the pediatric dentist's responsibility to supervise those children who seek to undergo a whitening treatment to ensure the maximum cosmetic benefit within the boundaries of oral and systematic health. Among bleaching techniques, the walking bleach technique with sodium perborate and distilled water stands out because of its superior esthetic results with no side effects. This paper presents a case of tooth discoloration in non-vital tooth which was successfully bleached using walking bleach method. After 6 year follow up the prognosis was good with no reversal of tooth discoloration and absence of external cervical resorption.

The purpose of this study was to examine the effect of hydrogen peroxide at different application time and concentrations on the microtensile bond strength of resin restorations to the deep and the pulp chamber dentin.A conventional endodontic access cavity was prepared in each tooth, and then the teeth were randomly divided into 1 control group and 4 experimental groups as follows: Group 1, non treated; Group 2, with 20% Hydrogen peroxide(H2O2); Group 3, with 10% H2O2; Group 4, with 5% H2O2; Group 5, with 2.5% H 2O2; the teeth of all groups except group 1 were treated for 20, 10, and 5min. The treated teeth were filled using a Superbond C&B (Sun medical Co., Shiga, Japan). Thereafter, the specimens were stored in distilled water at 37℃ for 24-hours and then sectioned into the deep and the chamber dentin. The microtensile bond strength values of each group were analyzed by 3-way ANOVA and Tukey post hoc test(p < 0.05).In this study, the microtensile bond strength of the deep dentin (D1) was significantly greater than that of the pulp chamber dentin (D2) in the all groups tested. The average of microtensile bond strength was decreased as the concentration and the application time of H2O2 were increased. Analysis showed significant correlation effect not only between the depth of the dentin and the concentration of H2O2 but also between the concentration of H2O2 and the application time(p < 0.05), while no significant difference existed among these three variables(p > 0.05). The higher H 2 O 2 concentration, the more opened dentinal tubules under a scanning electron microscope(SEM) examination.[J Kor Acad Cons Dent 34(5): [406][407][408][409][410][411][412][413][414] 2009]
