“…Some have identified cell-like processes in outer dentin (Sigal et al, 1984b), whereas other studies suggested that those structures are extracellular material lining the dentinal tubules (Thomas and Carella, 1984;Thomas, 1983). Therefore, there is evidence both for odontoblast extension to outer dentin and for restriction of OPs to inner dentin (for review see Holland, 1985Holland, ,1990Thomas, 1985).…”

There has been controversy about the length and structure of the odontoblast process within dentin since the earliest histologic studies of teeth. Our objective was to use the fluorescent carbocyanine dye Di-I combined with a new gelatin embedment procedure and confocal microscopy to determine the structure and extent of odontoblast processes in developing and mature rat teeth, injured rat molars, reparative dentin, and adult monkey teeth. We found that odontoblast processes do not extend into outer dentin or to the dentin-enamel junction except during early stages of development. Those in innervated regions of crown are long and straight, whereas those in roots are extensively branched and shorter. Cavity injury to crown dentin caused odontoblast fragments to be aspirated into outer dentin. In reparative dentin the odontoblast pmceses were branched and similar to those in roots. We used photoconversion and electron microscopy to show that Di-I f i i the entire odontoblast after gelatin embedment, including the cytoplasm. This is a different type of carbocganine staining from any previously reported, and it also stains other cells in adjacent hard tissues such as bone and cementum. The Di-I-gelatin method is a new way to use carbocyanine dyes. It has enabled us to solve a long-standing controvezsy about the histology of teeth, and it should be useful for many other studies of cell structure. ( J Hisrochem Cyrochem 43159-168, 1995)

“…The odontoblastic process is extremely fine and resides within dentinal tubules, which is like a capillary tube with a diameter that is much smaller than that of an erythrocyte. 10 After dentinogenesis, odontoblasts are aligned along the periphery of the dental pulp, thus playing a role in the maintenance of tooth integrity owing to their capacity of depositing new layers of dentin throughout life. In addition, newly differentiated odontoblast-like cells may also form a layer of reparative dentin after some tissue injuries.…”

Prokopowitsch I. Estudio de la variación de la permeabilidad de la dentina radicular usando isótopos 99m Tc, después de la aplicación de láser de alta intensidad RESUMENObjetivo: Este estudio tuvo como objetivo evaluar las variaciones de la permeabilidad dentinaria radicular de dientes humanos después del preparo químico-quirúrgico e irradiación con láser de Er: YAG, Nd: YAG, a través de la utilización del radioisótopo tecnecio-99m ( 99m Tc) libre. Materiales y métodos: Canales de treinta raíces palatinas de primeros premolares superiores humanos fueron preparados y divididos, aleatoriamente, en 3 grupos experimentales: G1 (control), G2 (irradiación con láser de Er: YAG) y G3 (irradiación con láser de Nd: YAG). Las muestras recibieron en el interior del canal radicular, 99m Tc libre en cantidad suficiente para el llenado y colocados en tubos de ensayo contiendo 1 ml de solución salina. Después de 1 hora, la cuenta del isótopo radioactivo ( 99m Tc) fue realizada. Resultados: Después del análisis estadístico (ANOVA), fue verificado que los mejores resultados obtenidos en cuanto a la disminución de la permeabilidad se encontraron en el Grupo 3, seguido del Grupo 2 y del Grupo 1. Conclusión: Concluimos que irradiación con láser de Nd: YAG provocó una disminución significativa de la permeabilidad dentinaria del canal radicular. El láser de Er: YAG y el control en relación a la permeabilidad de la dentina de las paredes del canal radicular no presentaron diferencias estadísticamente significativas a nivel de 5%.Palabras clave: Endodoncia, permeabilidad de la dentina radicular, Er:YAG, Nd:YAG, radioisótopo tecnecio99m (DeCS Bireme). SUMMARYObjective: The objective of this study was to evaluate changes in root dentin permeability of human teeth after chemical-surgical preparation, and laser irradiation with Er: YAG, Nd: YAG, through the use of the radioisotope technetium-99m ( 99m Tc) free.Estudio de la variación de la permeabilidad de la dentina radicular usando isótopos 99m Tc, después de la aplicación de láser de alta intensidad Study of the dentin root permeability variation using 99m
