El objetivo de este estudio era analizar los efectos de los campos electromagnéticos pulsantes (CEMP) sobre el desplazamiento dentario y el comportamiento óseo. El estudio se llevó a cabo sobre 9 machos de conejo de Nueva Zelanda, de 3,2 kg de peso. Se colocó un muelle de Sentalloy®, que producía 25 g de fuerza, entre el incisivo inferior y el primer molar en ambos lados de la mandíbula. En todos los animales se realizó un tratamiento ortodoncico de 14 dias. En el lado derecho se aplicó un campo electromagnetico de baja frecuencia durante 6 horas al día, siempre a la misma hora. Se registró un efecto facilitador del movimiento dentario por el CEMP y se observaron patrones histólogicos diferentes en el lado izquierdo y en el derecho: se encontro un aumento de la actividad osteoblastica y una mejor calidad de hueso en el lado sometido a los CEMP.The aim of this study was to analize the effects produced by Pulsating Electromagnetic Fields (PEMF) both on dental displacement and on bone behaviour. The study was carried out on 9 New Zealand male rabbits, 3.2 kg in weight. In both the left and the right side of the mandible a Sentalloy® coil spring, producing a force of 25 g was attached between the lower incisor and the first molar. The orthodontic treatment was performed in all animals for 14 days. The right side of the mandible received a low frequency pulsed electromagnetic field treatment for 6 hours per day, always at the same time of day. A facilitating effect of the PEMF on tooth displacement was recorded and different histologic patterns were observed in the left and in the right sides: an increased osteoblastic activity and a better quality bone were found in PEMF-treated mandibles.

Abstract

El estudio se llevó a cabo sobre 9 machos de conejo de Nueva Zelanda, de 3,2 kg de peso. Se colocó un muelle de Sentalloy®, que producía 25 g de fuerza, entre el incisivo inferior y el primer molar en ambos lados de la mandíbula. En todos los animales se realizó un tratamiento ortodoncico de 14 dias. En el lado derecho se aplicó un campo electromagnetico de baja frecuencia durante 6 horas al día, siempre a la misma hora. Se registró un efecto facilitador del movimiento dentario por el CEMP y se observaron patrones histólogicos diferentes en el lado izquierdo y en el derecho: se encontro un aumento de la actividad osteoblastica y una mejor calidad de hueso en el lado sometido a los CEMP.The aim of this study was to analize the effects produced by Pulsating Electromagnetic Fields (PEMF) both on dental displacement and on bone behaviour.
