Quantification of TRAP(+) mononuclear and multinuclear cells, and resorption pits formed on the dentine slices shown in Figure 2(A).

Culture time (days)	No. of TRAP(+)mononuclear cells	No. of TRAP(+)multinuclear	Ratio of multinuclear to mononuclear cells (%)	No. of resorption pits
7	37667 ± 444	172 ± 111	0.46 ± 0.29	0 ± 0
14	29536 ± 2850	1160 ± 135	3.93 ± 0.46	40 ± 8.67
21	29294 ± 2440	1198 ± 155	4.09 ± 0.53	310 ± 56.2

The results are expressed as the mean ± SE of six cultures. Similar results were obtained in two independent experiments.
