dc.description.none.fl_txt_mv Objective. To verify the thickness of dental hard tissues at present. Methods. Observational, descriptive and cross-sectional study. Ninety four human permanent teeth existing in the library of the Faculty of Dentistry of the National Northeast University were collected during 2004-2014, these were free of injuries and restorations, with full crowns and root were used. Eight samples from each group (incisors, canines, premolars, and molars) were selected to measure the thickness of hard tissues of incisal, occlusal, central, cervical, and apical thirds. A Model AA flat vice and carborundum discs were used in a Dremel 4000 micromotor to make longitudinal cuts in the mesiodistal direction of each selected piece and the surface was polished with a pumice stone until minimum thickness was obtained. The measurement was made in millimeters with a digital microscope, resolution up to 2M pixel, 25 - 400x. Results. The thickest tissue in all the dental groups was dentin whose value was 1.53 mm to 5.16 mm, enamel followed in order with 0.87 mm to 3.47 mm depending on the location, and the thinnest tissue was cement with values between 0.18 mm and 0.78 mm. The greatest thickness of enamel and dentin was registered in the premolar group, while the greatest thickness of cement, in the molar group. Conclusion. This work has allowed us to observe significant differences in the thickness of the dental tissues, measured in permanent human teeth.
Objetivo. Verificar el espesor de los tejidos duros dentarios en la actualidad. Métodos. Estudio observacional, descriptivo y transversal. Se utilizaron 94 piezas dentarias permanentes naturales y humanas existente en la morfoteca de la facultad de odontología de la Universidad Nacional del Nordeste y recopiladas durante 2004 al 2014, libres de lesiones, restauraciones, con corona y raíz completas. Se seleccionaron ocho muestras de cada grupo (incisivos, caninos, premolares y molares) para medir el espesor de los tejidos duros en los tercios incisal, oclusal, central, cervical y apical. Se utilizó una morsa plana modelo AA y discos de carborundum en micromotor tipo Dremel 4000 para realizar cortes longitudinales en sentido mesiodistal, de cada pieza seleccionada y se procedió a pulir la superficie con piedra pómez hasta obtener el mínimo espesor. La medición se realizó en milímetros con digital microscope, resolution up to 2M pixel, 25-400x. Resultados. El tejido de mayor espesor en todos los grupos dentarios fue la dentina cuyo valor fue 1,53 mm a 5,16 mm. Le siguió en orden el esmalte con 0,87 mm a 3,47 mm según el lugar de ubicación y el tejido más delgado lo representó el cemento con valores entre 0,18 mm y 0,78 mm. El mayor espesor de esmalte y dentina fue registrado en el grupo premolar, mientras que el mayor espesor de cemento, en el grupo molar. Conclusión. El trabajo realizado ha permitido observar diferencias significativas en los espesores de los tejidos dentarios, medidos en piezas dentarias permanentes humanas.
