Resumen
La enfermedad periodontal es una de las patologías más prevalentes del sistema
estomatognático, y su principal tratamiento es el pulido radicular durante décadas el
método de elección para realizar este procedimiento fue la instrumentación manual
utilizando curetas. Con los avances tecnológicos se introdujo a este ámbito la utilización
de instrumentos ultrasónicos que utilizan un sistema de vibración con un rango de
frecuencia que oscila entre los 24.000 y 42.000 Hz y un rango de amplitud que va de
los 10 a 100 μm. Este método demostró ser más eficiente en la remoción de
cálculos debido a la disminución de los tiempos clínicos de 5,9 a 3,9 minutos por pieza.
A pesar de las ventajas que tiene utilizar el ultrasonido, se ha visto que este puede
tener efectos adversos sobre el tejido radicular, diversos estudios han demostrado que
este daño es mayor en comparación a la impronta dejada por las curetas, mientras
otros estudios determinaron que la instrumentación manual produce más daño en el
cemento radicular ; entonces, ¿La instrumentación con ultrasonido, produce más
daño al tejido radicular que la instrumentación manual?.
Periodontal disease is one of the most prevalent diseases of the stomatognathic system, and its main treatment is root planing. for decades the method of choice far this procedure was hand instrumentation using curettes. With technological advances in this field ultrasonic instruments was introduced using vibration waves with a frequency range between 24,000 and 42,000 Hz and an amplitude range that goes from 10 to 100 um. This method preved to be more efficient in the removal of calculus due to the decrease of clinical times from 5.9 to 3.9 minutes. The present research aims to determine whether ultrasonic root debridement mecanorestrictive produces more wear than curettage manual for this, we use a analytical experimental with contemporary controlled in vitro study. The sample consisted in-20 healthy third molars extracted, which were cut in its long axis to obtain a sample number of 40 specimens, standardizing with it the quantity and quality of root cement, these samples were separated into two groups one "A "and one" B ". The root surface of the teeth of group "A" was treated with curettes graecy Hu-fraedy® sg7/8r6, the group "B" were treated with ultrasound mecanorestrictive Dentsply® Cavitron® Bobcat®. Pictures were taken through stereoscopic microscope befare and after instrumentation, and were mounted in Adobe® Photoshop® CS6 for measurement. The results were subjected to t-student test which was highly significant (p <0.001 ), thereby determining that the ultrasonic treatment of the root surface Wearing a 30.6% less cement than conventional treatment manual.
