Abstract:

Objective　To observe osteoclasts on the resorbing surface of human deciduous teeth.Methods　After fixing the collected deciduous teeth, we prepared the tooth sliceswithout decalcification, treated themwithHE andTRAP dyestuff, and ob- served the osteoclasts under light and scanning electronmicroscope.Results　Therewere large quantity of various forms of overlap- ping and huge osteoclastswith many nuclei and silk-like protuberances on the resorbing surface of deciduous teeth. The multinu- cleated osteoclasts align on the surface of coarse dentin.Conclusion　On the resorbing surface of human deciduous teeth there are large amount of osteoclasts which can be used as a source of studying human osteoclast.

Key words: deciduous teeth, osteoclasts, morphology
