title: [Semiquantitative study of periodontolysis and experimental bone repair in the golden hamster].
abstract: 80 golden hamsters received Keyes high carbohydrate diet 2 000 and a therapy with the unsaponified fraction of corn germ oil extract (UCOE). 40 hemialveolar molar sockets were preserved and a quantitative study was carried out with the scanning electron microscope and the use of two statistical methods. The effects of UCOED are: a reduction of resorption areas, a decrease in size of resorption lacunae and an increase in the attachment surface of periodontal fibres. These results are connected to the quantity of UCOED ingested. Further, the quantifying of the resorption areas indicates that the periodontal lesions induced by Keyes diet 2 000 are balanced by the ingestion of 20 mg/kg/per day of UCOED, whereas the ingestion of 50 mg/kg/per day induced a larger increase in bone apposition.
