ABSTRACT

Objetivo: el objetivo de este estudio fue evaluar la deformación longitudinal en conductos curvos artificiales instrumentados con las limas mecánico-rotatorias de niquel titanio HERO Shaper y RaCe, determinar el calibre y conicidad de la lima maestra apical, así como la primera lima que inició la deformación. Material y métodos: Un total de 20 conductos curvos artificiales fueron distribuidos aleatoriamente en dos grupos de 10 cada uno. Se prepararon los conductos utilizando la técnica crown-down. Se superpusieron las imágenes obtenidas mediante observación estéreo-microscópica de un mismo conducto radicular antes y después de su instrumentación. Se mantuvieron la posición y los aumentos en las observaciones realizadas con todas las muestras utilizadas en este estudio. Los datos obtenidos fueron analizados utilizando el test de Kruskal Wallis y el test de la U de Mann Whitney. Resultados: Se prepararon los cubiletes del grupo RaCe con una secuencia menor de limas. La preparación del tercio coronal, con ambos sistemas, fue homogénea amentando la deformación en el tercio medio y parte del tercio apical. La deformación en la preparación de los últimos dos milímetros fue menor con la límas RaCe que con las de HERO Shaper. La primera lima que inició la deformación con RaCe fue de igual conicidad y de calibre mayor que HERO Shaper. Conclusiones: Bajo las condiciones de este estudio RaCe mantuvo mejor la curvatura original del conducto artificial que HERO Shaper (AU)


Objective: The aim of this study was to evaluate the longitudinal transportation of artifically curved canals instrumetne with two Rotary Niti systems (HERO Shaper and RaCe), as well as to determine the size and the taper of the apical master file, and the size and taper of the first file which started the transportation. Methodology: 20 artificially curved canals ( plastic blocks) were prepared, and divided into 2 groups of 10: group HS (prepared with HERO files) and group RC (prepared with RaCe files). The canals were instrumented according to the crown-down technique. Pre-op and post-op pictures of the same canals were superposed for a stereoscopic observation. All samples of this study were examined under the same conditions: position and image magnification. The results were analyzed according to the Kruskel Wallis and Mant Whitney LL test. Results: The plastic blocks of the RaCe group were instrumented in a shorter sequence. No difference was observed in the preparation of the coronal third between the systems. However the transportation increased in the middle and apical thirds. The first RaCe file that started trasportation was of the same taper but of a larger diameter than the HERO Shaper. Conclusions: According to our study, RaCe respected the original curvature of the artificial canal better than HERO Shaper (AU)

ABSTRACT

Objetivo: Se evaluó comparativamente la presencia de smear layer residual tras la instrumentación de conductos con dos sistemas de instrumentación diferentes; uno con apoyos radiales: ProFile y otro sin ellos: RaCe. Metodología: Se seleccionaron 15 conductos de molares extraídos y se distribuyeron aleatoriamente en tres grupos de 5 cada uno (grupo PP: motor eléctrico de una velocidad de 300 r.p.m. y un torque dinámico AP-10. En los tres grupos, la irrigación entre cada instrumento se realizó alternando 2 ml de NaOCI (5,25%) y 2 ml de ác. Cítrico 820%9. La limpieza de las paredes de los conductos se estudió con Microscopia electrónica de barrido utilizando 5 categorías para cuantificar la cantidad de smear layer a 1000 aumentos. El análisis estadístico de los resultados se realizó con el test de Kruskal-Walls y la U de Mann-Whitney (...) (AU)


Aim: Compare the smear layer left on canal walls after rool cannal instrumentation with two different systems: one with radial lands - Profile and another without radial lands - RaCe. Methodology: 15 molar root canals were divided into 3 groups of 5. Group PF; Profile, group Rc: RaCe, group RCSA: RaCe and S-Apex. there were all run in a 1:18 WH reducing contra-angle on an electric motor, at a 300 rpm speed and AP-10 dynamic lorque. For all groups, irrigation was performed alternating 2 ml NaOCU (at 5,25%) and 2 ml citric acid (at 20%) after each instrument. Cleaning of canal walls was observed under SEM at a 1000x magnification, using a 1 to 5 scale to quantify the amount of semera layer left. Satitiscial analysis of the results was made using the Kruskal Walls and Mann-Whitney U test (...)(AU)

ABSTRACT

El propósito de este estudio fue comparar la cantidad de dentina radicular removida y evaluar el mantenimiento de la forma del conducto tras la instrumentación de los dos tercios coronarios radiculares, utilizando instrumentos de acero inoxidable (taladros de Gates Glidden) y de níquel-titanio (limas GT Flare y limas Orifice Shaper). Un total de 42 dientes humanos extraídos con conductos radiculares curvos fueron divididos en tres grupos. Los conductos se instrumentaron mecánicamente usando taladros de Gates Glidden, limas Orifice Shaper o GT Flare con la técnica corono-apical. Este estudio se realizó siguiendo la técnica de Bramante modificada. Las secciones transversales de cada conducto fueron efectuadas a tres niveles horizontales diferentes (a 2, 4 y 6mm de su inicio en la cámara). Antes y después de la instrumentación fueron observados y fotografiados para luego ser medidos. A cada nivel se valoraron dos parámetros, el mantenimiento de la forma original del conducto y la cantidad de dentina removida. El análisis estadístico reveló que existían diferencias estadísticamente significativas (p<0,05) a, nivel de los cortes a 4 y 6 mm en la cara interna del conducto; mientras que la preparación del mismo más prevalente fue excéntrica sin ensanchar todas las paredes del conducto


The purpose of this study was to compare the amount of the dentine removed and to evaluate the maintenance of the original shape of root canals after the filing of two thirds coronary root canals using instruments of stainless-steel (Gates Glidden drills) and nickel-titanium (GT Flare and Orifice Shaper files). A total of forty-two extracted human teeth with curved root canals were divided in three groups. They were instrumented mechanically using Gates Glidden drills, Orifice Shaper files or GT Flare files with the crown-down technique. This study was done following the modified Bramante technique. The crossed sections of every root canal were done at three different levels (at 2, 4 and 6mm from pulp chamber). Before and after the filing process, these sections were photographed to be mesured. Two parameters were evaluated in every section, the maintenance of the original of the root canal shape and the amount of dentine removed. Statistical analysis revealed significant differences (p<0,05) between the crossed sections at 4 and 6mm in the inner face; while the excentric shapes, without widen all canal walls, was the most frequent

ABSTRACT

A comparative study of the absorbency properties of different endodontic paper points has been conducted. Twenty standardized absorbent paper points, size 30, from 13 bands (Dentaline, Zipperer, Kerr, Diadent, Roeko novo, Roeko color, Maillefer, P.D., Schein, Spectrapoint, Proclinic, Euronda, and Alpro) of 12 manufacturers were tested. Each dry paper point was weighted using an electronic laboratory balance. A length of 16 mm from the tip was then lowered in distilled water for 5 s, the paper point was weighted again, and the difference between both measurements was taken as the value of the fluid absorbed. Diadent, Kerr, and Dentalite showed significantly higher absorbencies (p < 0.05) than standardized paper points of the remaining brands. The study demonstrates a wide variation in the absorbency properties of this dental accessory.

ABSTRACT

The aim of the work was to evaluate the bone density of chronic periapical lesions in the area of maxillary incisors and canines. Twenty-six radiographies were made in a systematic way in patients with periapical lesions and were valued using densitometry (0-256), the grey levels by computer and the analysis program image (IBAS 2000 Kontron, Germany), taking four values in each periapical lesion from the center to the periphery within the same radiography, by using the pseudocolor to identify the four areas, always in the same coloration. Correlation was proved with significative statistically results between lower densitometric values and osteolysis and radiolucency areas.

ABSTRACT

The time taken to achieve the sterilization of K files impregnated in a Bacillus subtilis culture was evaluated, placing the files in a glass bead sterilizer. The minimum time needed was 20 seconds at 240 degrees C and the previous cleaning of the file with a sterile wipe impregnated by alcohol reduced this time to 15 seconds.
