dc.description.abstract | Introducción: Estudio experimental donde se procuró determinar el efecto osteoinductor del mineral trióxido agregado (MTA) versus el cemento Portland tipo I sobre lesiones óseas mandibulares. Metodología: Se emplearon 12 conejos machos de la raza New Zealand de 3 meses de edad, los cuales fueron divididos en 4 grupos iguales. Todos los conejos fueron anestesiados utilizando pentobarbital sódico. Se procedió a la incisión en la piel mandibular para exponer el hueso sobre el que se realizó 3 cavidades de 3mm cada una. En una cavidad se colocó MTA, en otra cemento Portland y en la tercena ninguna pasta. Se procedió al sacrificio de los grupos experimentales a la 1era, 2da, 3era y 4ta semana respectiva y se evaluó las muestras obtenidas de las áreas quirúrgicas mediante conteo de osteocitos y osteoblastos. Resultados: Tanto el MTA como el cemento Portland poseen la misma capacidad osteoinductiva en la 1era, 2da y 3era semana (p>0,05). Sin embargo, en la 4ta semana el MTA tuvo mayor capacidad osteoinductora al estimular mayor número de osteoblastos que el cemento Portland (p=0,024). Conclusiones:El MTA y el cemento Portland tipo I mostraron similar efecto osteoinductor durante las 3 primeras semanas de evaluación. El MTA demostró mayor efecto osteoinductor durante la cuarta semana de valoración. | en_US |
dc.description.abstract | Abstract: Introduction: An experimental study was carried out to determine the osteoinductive effect of Mineral Trioxide Aggregate (MTA) versus Portland Cement type I on mandibular bone lesions. Methodology: Twelve 3-month-old male New Zealand rabbits were divided into 4 equal groups. All rabbits were anesthetized using Pentobarbital. An incision of the mandibular skin was performed to expose the bone on which 3 cavities of 2mm each one were made. In one cavity MTA was placed, in another Portland Cement type I and the third remained empty. The experimental groups were sacrificed at the 1st, 2nd, 3rd and 4th respective weeks and evaluated histologically by counting osteocytes and osteoblasts. Results: Both MTA and Portland cement have the same osteoinductive capacity in the 1st, 2nd and 3rd week (0.05 <p). Nonetheless, in the 4th week the MTA had greater osteoinductive capacity by stimulating a greater number of osteoblasts than the Portland Cement (p = 0.024). Conclusions: The MTA and Portland cement type I showed a similar osteoinductive effect during the first 3 weeks of evaluation, however, MTA had the greatest osteoinductive effect during the fourth week of evaluation. | - |
