Surgical lesions in rat condylus were treated with N,N-dicarboxymethyl chit
osan and 6-oxychitin sodium salt. Morphological data indicate that the best
osteoarchitectural reconstruction was promoted by 6-oxychitin, even though
healing was slower compared to N,N-dicarboxymethyl chitosan. Complete heal
ing was obtained with N,N-dicarboxymethyl chitosan within three weeks. (C)
