ABSTRACT
New alveolar Bone vs. Native alveolar Bone ot Cobayos. This survey has the aim to know the cronological changes of new bone of cobayos. This regenerated bone was clinically screened after using clorhexidine 0.12 por ciento, collagen membrane loaded with it, 10 and 13 mg of doxyciclyne solution and collagen loaded with them. The sample was formed by six cobayos and the reentry was done after four weeks. We had observed the histological characteristics: citoplasm, woven bone, wide and numerous marrow spaces, incremental and traverse lines and multi-nucleated osteoclasts. Native bone had a dense lamellar bone, with reduced marrow spaces and a low basophilic citoplasm.

This experimental survey has he aim to reproduce periodontal disease in Cobayos. As risk factors, we have prepare a cariogenic diet rich in sacarosa which is a substrate for microorganisms, producing more energy for its metabolism and acids which lows pH. Sacarosa is degradated in fructanos and dextrans which stores carbohydrates in Dental Plaque. We had also used ligatures and amalgam fillings to retain plaque. We had clinical signs of gingivitis since y 7th day. This survey lasted a month. We could see, bleeding, redness swelled gums and gingival recession as days went ori.

Este caso es de un paciente diabético con duración de 08 años, actualmente controlado. Fue tratado en la clínica de la U.I.G.V. La enfermedad periodontal activa ha destruido el periodonto perdiendo varias piezas dentarias. Hoy, compensando con 123 mg./ dl Glucosa, previa fase inicial, se determinó hacer la técnica de RTG con autoinjerto óseo logrando preservar la pieza 2.3 de pronóstico reservado. Al examen radiográfico tomado después de 4 meses se ha ganado hueso e inserción conectiva.
