Sixth young albino rats were used. After extracting the maxillary right incisors all the rats, three experimental groups were formed: the control (I) and the groups that received 1.25 Sv (II) and 1.75 Sv (III). The rats were killer at 3, 7, 14 and 28 post-operative days following the teeth extraction. The pieces obtained were submitted to routine laboratorial procedures until getting pieces stained with hematoxylin and eosin. It was concluted that: 1) there was a delay in the epithelial proliferation of the gengival mucosa o the animals submitted to X-rays, in a similar way in the two irradiated groups: 2) there was a considerable delay in the alveolar repair process in dental extraction wound; 3) this delay was more proeminent when the X-ray action was more intense.
