The aggressive periodontitis might to provoke the tooth loss, of its function and to affect the patient's aesthetics. The techniques used for the lost bone regeneration, not always are successful and in occasions are very expensive. For years it is working in tissues regeneration by stem-cells implantation. Periodontium could be a potential for this task. This is a study of a female patient aged 26 with an apparent health status and aggressive periodontitis backgrounds treated from 10 years ago, seen in our service due to dental mobility producing mastication nuisances. At clinical examination we noted systemic chronic inflammation of gums, grade II and III dental mobility in incisives and molars teeth, 4-8 mm systemic periodontal sacs and furcation lesions in inferior molars. At radiographs advanced bone losses and a decrease of systemic bone density are noted. After written consent and the initial preparation, we carried out a periodontal flap in the 35 and 37 teeth zone, where the stem-cells concentrate was placed, in bone defects of superior molars (16-17) and previous radicular scraping and isolation, treatment consisted in stem-cells perfusion without flap. There were not postoperative side effects. At 7 days there was a normal coloration, at three months on noted at radiograph a bone neoformation, and at six months gum remained healthy, with a decrease of dental mobility in segment treated and in the evolutionary radiograph it was evidenced the formation and increase of density.
