The aim of this study was to characterize the dental cementum in the dog using the scanning electron microscope (SEM). The buccal surface of 38 dental roots was observed and photographed with the SEM in their coronal and apical thirds. A morphological classification of the surface was performed and also, the diameter of 20 Sharpey fibers was measured in each picture establishing the percentage occupied by them in 600 µm². In the coronal third, acellular cementum was found with the Sharpey fibers closely packed, projecting perpendicular to the surface, occupying almost the whole of it. The diameter of the fibers was of 5.31 ± 0.98 µm. In the apical third, cellular cementum was found, with a density of Sharpey fibers less tham 55%, the remainder being intrinsic fibers and cell lacunae. The fiber diameter was 5.47 ± 1.31 µm. The diameters of Sharpey fibers of the apical third were significantly higher (p=0.0000) than those in the coronal one. We conclude that the dog cementum surface is not uniform, being differences between coronary and apical thirds and within the same third of the tooth. Fil: Toriggia, P.G. Universidad de Buenos Aires.

Ciappesoni, J.L. 2011 El objetivo del trabajo fue caracterizar el cemento dental en el perro utilizando para ello el microscopio electrónico de barrido (MEB). La cara vestibular de 38 raíces dentales fue observada y fotografiada con el MEB, en sus tercios coronario y apical. Se realizó una clasificación morfológica de la superficie y se midió en cada microfotografía el diámetro de 20 fibras de Sharpey, estableciéndose el porcentaje que ocupaban en 600 µm². En el tercio coronario se encontró un cemento de tipo acelular, con fibras de Sharpey densamente agrupadas, proyectándose perpendicularmente a la superficie, ocupando casi su totalidad. El diámetro de las fibras fue de 5.31 ± 0.98 µm. En el tercio apical, se encontró un cemento celular con una densidad de fibras de Sharpey menor al 55%, siendo el resto fibras intrínsecas y lagunas celulares. El diámetro de las fibras fue de 5.47 ± 1.31 µm. Los diámetros de las fibras de Sharpey del tercio apical fueron significativamente mayores (p=0.0000) que aquellos del tercio coronario. Concluimos que la superficie del cemento del perro no es uniforme en toda su extensión, presentando variaciones entre los tercios coronario y apical, así como también dentro del mismo tercio del diente. application/pdf 1514-6634 (impreso) 1668-3498 (en línea) cemento dental ultraestructura MEB perro dental cementum ultrastructure SEM dog spa Universidad de Buenos Aires.

The aim of this study was to characterize the dental cementum in the dog using the scanning electron microscope (SEM). The buccal surface of 38 dental roots was observed and photographed with the SEM in their coronal and apical thirds. A morphological classification of the surface was performed and also, the diameter of 20 Sharpey fibers was measured in each picture establishing the percentage occupied by them in 600 µm². In the coronal third, acellular cementum was found with the Sharpey fibers closely packed, projecting perpendicular to the surface, occupying almost the whole of it.
