ABSTRACT

Objetivo: determinar la actividad de un injerto basado en el cocultivo de fibroblastos gingivales y queratinocitos en membrana de colágeno comercial Mem-Lok(R) (BioHorizons), Alabama, Estados Unidos) en el tratamiento de recesiones gingivales. Materiales y métodos. Esta investigación fue descriptiva y de diseño experimental. La muestra se conformó de 10 ratas Sprague Dawley a las que se indujeron recesiones gingivales. A 8 de ellas se les aplicó el injerto y las 2 restantes no recibieron tratamiento. Resultados: el análisis descriptivo de los resultados determinó la posibilidad de obtener un cocultivo celular. Luego de la aplicación del injerto, las características clínicas periodontales indicaron salud, consistencia firme, textura a manera de puntillado, contorno festoneado, biotipo grueso, sondaje periodontal de 1 mm y posición de la encía a nivel del límite amelocementario. Conclusiones: el injerto aplicado logró una cobertura radicular del 100 por ciento en todos los casos. No se observó sangrado ni contracción cicatrizal.


Aim: to determine the effectiveness of a graft based onco-cultivation of gingival fibroblast and keratinocytes in commercial collagen membrane Mem-Lok® (BioHorizons, Alabama,USA) in the treatment of gingival recessions. Materials and methods: This research was descriptiveand experimental in design. The sample was composed of 10 Sprague Dawley rats which were induced gingival recession; two of them were not treated and the graft was applied in eightof them. Results: A descriptive analysis of the results was performed, which showed that it was possible to obtain a cellco-culture. After the application of the graft, clinical periodontal characteristics were observed that indicated health: the consistency was firm, the texture resembled dots, scallopedand knife edge margin, a thick biotype and the depth ofgingival sulcus was 1 mm. Conclusions: The applied graft achieved a 100% radicularcoverage in all cases and no bleeding or scar contractionwas observed.
