[The bony modifications in the periodontal pockets].
The aim of this study was to demonstrate the bony structural changes in deep periodontal pockets.


METHODS
Bony fragments were taken from the alveolar wall of a group of 24 patients diagnosed with deep periodontal lesions which required the extraction of certain irrecuperable teeth. Fragments were fixed in glutaraldehyde, then decalcified in EDTA 5% and proccesed for electron microscopic examination and a semifinesse sections to microscop "Zeiss Axioscop".


RESULTS
Both optic and electron microscopy showed: decreaze of bone mineralization and alterations in cholagen structure; the presence of osteoclasts with intense activity and numerous macrofages; at the level of bone marrow, small, insignificant inflammatory reactions, contrasting with the important surrounding modifications; in certain cases though osteolytic reactions occured, the osteoclasts could not by evidenced, on the contrary, numerous macrophages with intense lysosomal enzymes activity were noticed; all the cases showed an alteration of the alveolar bone cholagen.


CONCLUSIONS
Thus, we can better understand the role of primary factors in this bony structures.
