| Research Abstract |
Some factors that suppress osteoclast activity are contained in both deciduous and permanent dentin organic matrix extracts. Although there was no significant difference in osteoclast activity between deciduous and permanent dentin extracts, osteoclasts incubated with permanent dentin extracts tend to exhibit less resorption activity than those incubated with deciduous dentin extracts.
