Abstract: El presente estudio evaluó la biocompatibilidad de un cemento a base de la asociación Uncaria tomentosa (Willd) D.C. e Hidróxido de Calcio, así como la de un cemento tipo Grossman- Endofill.
Se utilizaron 37 ratas albinas raza Holdzman americanas, sexo masculino, de tres meses de edad, de peso 300gr. aproximadamente. Un animal fue sacrificado sin colocarle ningún implante para evaluar la anatomía normal de la ratas. Las demás fueron divididos en tres grupos: grupo A o control, con implante vacío; grupo , con el cemento asociación; y el grupo C, con el cemento tipo Grossman.
A cada animal se le colocaron dos implantes con el material a evaluar, uno a cada lado del lomo. Los animales fueron sacrificados luego de periodos de 1, 3, 7 y 21 días.
Luego de obtenidas las muestras, el análisis microscópico demostró que en los dos primeros periodos los cementos produjeron una inflamación de tipo aguda, y en los últimos periodos una inflamación de tipo crónica.
Todos los materiales produjeron reacción inflamatoria, sin embargo el grupo control y el Grupo B correspondiente al cemento asociación, mostraron los menores niveles de inflamación. Además, en el Grupo B en el último periodo se observaron muestras de reacción tisular fibroblástica notorias.
El cemento tipo Grossman, a base de Oxido de zinc-eugenol, demostró mayor reacción tisular inflamatoria, la cual disminuyó en el último periodo.
La reacción inflamatoria con el cemento asociación fue de menor intensidad, produciéndose una respuesta histológica favorable, aceptándose como un material biológicamente aceptable. Se recomienda estudiar este cemento en periodos más largos de estudio y mejorar las propiedades físicas.
The present study evaluated the biocompatibilidad of a cement with the help of the association Uncaria tomentosa (Willd) D.C. and Calcium Hidroxide, as well as that of a cement type Grossman - Endofill. 37 rats white race American Holdzman was used, sex male, three age months, of weight 300gr. approximately. An animal was sacrificed without placing him any it implants to evaluate the normal anatomy of the rats. The other ones were divided in three groups: group A or control, with it implants hole; group B with the cement association; and the group C, with the cement type Grossman. To each animal they were placed two you implant with the material to evaluate, one to each side of the loin. The animals were sacrificed after periods of 1, 3, 7 and 21 days. After having obtained the samples, the microscopic analysis demonstrated that in the first two periods the cements produced a sharp type inflammation, and in the last periods a chronic type inflammation. All the materials produced inflammatory reaction, however the group control and the Group B corresponding to the cement association, showed the smallest inflammation levels. Also, in the Group B in the last period samples of reaction tisular notorious fibroblástica were observed. The cement type Grossman, with the help of Oxide of zinc-eugenol, it demonstrated bigger reaction inflammatory tisular, which diminished in the last period. The inflammatory reaction with the cement association was of smaller intensity, taking place an answer favorable histologic, accepting you as a biologically acceptable. It is recommended to study this cement in longer periods of study and to improve the physical properties.
