Summary: | To determine differences between bone healing and soft tissues in the lower jaw of patients subjected to impacted third molar extraction after using a high and low speed rotary devices.
Crossed clinical assay-type intervention study. Under local anesthsesia, forty tooth extractions were performed (right and left) from 20 healthy patients. Two groups were thus formed: in group 1 high speed hand-piece was used, in group 2, low speed hand-piece was employed. Index cards were used to record time devoted to each patient as well as preoperative and postoperative clinical data related to inflammation, pain, opening limitations, bone healing and periodontal changes in the adjacent teeth.
When comparing high and low speed hand-pieces, statistically significant differences were found between pain, surgical time and probing depth; it was observed that low speed hand-piece generated lesser aggression to soft tissues.
Accurate use of low speed hand-pieces allows a decrease of surgical time thus providing the patients with more suitable postoperative evolution.
Determinar las diferencias en la cicatrización ósea y tejidos blandos en el maxilar inferior de pacientes sometidos a exodoncia de terceros molares incluidos después de la utilización del instrumental rotatorio de alta y baja velocidad.
Estudio de intervención tipo ensayo clínico cruzado, se efectuaron 40 extracciones dentarias (derechas e izquierdas) en 20 pacientes sanos bajo anestesia local, para lo que se formaron dos grupos: en el grupo I se utilizó la pieza de alta velocidad y en el grupo 2 la pieza de baja velocidad; se registró en una ficha el tiempo empleado en cada paciente y los datos clínicos preoperatorios y postoperatorios con relación a la inflamación, dolor, limitación de la apertura, cicatrización ósea y cambios periodontales a nivel de órganos dentarios adyacentes.
Existen diferencias estadísticamente significativas entre dolor, tiempo quirúrgico y en la profundidad al sondaje entre la pieza de alta y baja velocidad siendo la pieza de baja la que genera menor agresión a los tejidos blandos.
El adecuado empleo de la pieza de baja velocidad permite una reducción del tiempo quirúrgico proporcionando una mejor evolución postoperatoria a los pacientes. |
