Oxytalan fibers in peripheral odontogenic fibromas. A histochemical study of eighteen cases.

Oxytalan fibers, identified by histochemical methods alone, were found embedded. Since oxytalan fibers have been found embedded in bone in the periodontal ligament, the finding of these fibers in the calcified material of peripheral odontogenic fibromas adds considerable weight to the assumption that these lesions are of periodontal ligament origin.
