Abstract:
OBJECTIVETo investigate the degradation of electrodeposited calcium phosphate (ECP) coating and calcium phosphate/chitosan (ECPC) coating in vitro.
METHODSOsteoclasts were isolated from neonatal rabbit long bone cavities and incubated with ECP and ECPC coatings. Calcium ion concentrations in the culture medium were analyzed at 3 days and 6 days. The osteoclastic resorption was observed with scanning electron microscope.
RESULTSBoth coatings demonstrated osteoclastic resorption lacunae. The calcium ion concentrations of the culture mediums were decreased when incubated with calcium phosphate coatings (P < 0.05). Compared with coatings cultured with osteoclasts, the calcium ion concentrations of those cultured without osteoclasts were higher on day 3 (P > 0.05) but lower on day 6 (P < 0.05).
CONCLUSIONSBoth ECP and ECPC coatings can be resorbed by osteoclasts in vitro and can dissolve in the culture medium.
