Resumen
El análisis de este estudio tuvo como finalidad determinar la evaluación de la preparación del tercio cervical del conducto mesiovestibular del primer molar superior con fresas gates glidden y con instrumentos manuales protaper. Analizar y comparar el desgaste compensatorio de dos técnicas de instrumentación, el sistema rotatorio gates glidden y sistema manual Protaper con el fin de cuantificar la cantidad de dentina removida en la porción cervical del conducto mesiovestibular del primer molar superior. Se realizó los desgastes compensatorios Se tomó la muestra de 10 primeros molares superiores divididos en dos grupos de 5.Los dientes fueron divididos e instrumentados con gates glidden y manuales protaper, para la medición del tercio cervical del conducto mesiovestibular las referencias anatómicas que se midieron fueron remanente mesial del conducto mesio- vestibular, vestibular del conducto mesiovestibular, mesial del conducto disto vestibular, vestibular del conducto distal y distancia entre la pared distal del conducto mesiovestibular con la pared mesial del conducto vestíbulo distal. Los resultados fueron analizados en milímetros con un programa de medidas klonk imagen. El método utilizado es teórico- analítico y sintético, según el estudio in vitro se concluye que las limas manuales protaper causan un menor desgaste en el tercio cervical utilizando toda la secuencia de instrumentación, mientras que con las fresas gates glidden se obtuvo un mayor desgaste en el tercio cervical, se encontró discrepancia estadísticamente. Las fresas gates glidden que realizan un desgaste compensatorio más agresivo.

The analysis of this study aimed to determine the evaluation of the preparation of the cervical third of the Canal mesiovestibular of the upper first molar with gates glidden strawberry and hand instruments protaper. Analyze and compare the countervailing duty wear of two techniques of instrumentation, the rotary system gates glidden and manual system protaper in order to quantify the amount of dentine removed in the cervical portion of the canal mesiovestibular of the upper first molar. Was the countervailing duties wear the sample of 10 upper first molars divided into two groups of 5. Teeth were divided and instrumented with gates glidden and manuals protaper, for the measurement of the third cervical duct mesiovestibular anatomical references that were measured were mesial of duct remnant mesiovestibular, vestibular mesiovestibular, mesial of duct duct disto vestibular, the distal duct vestibular and distance between the distal wall of the duct mesiovestibular with mesial of duct distal lobby wall. The results were analyzed in millimetres with a program of measures klonk image. The method used is theoretical-analytical and synthetic, according to the study in vitro concludes that you limes manuals protaper cause a minor wear on the cervical third using the entire sequence of instrumentation, while with strawberries gates glidden won an increased wear in the cervical third is found discrepancy statistically. The gates glidden strawberry making a more aggressive compensatory wear. Key words: Wear compensatory, discrepancy, Rotary, manual.
