Optical density of Wnt3a in the bone cells in the third inflammatory area of alveolar crest (n = 8, $\overline{X}$ ± SD).

Time (wk)	Optical density of positive cells
	N	P
2	0.54 ± 0.03	0.57 ± 0.03
4	0.53 ± 0.04	0.43 ± 0.07*,**
6	0.57 ± 0.02	0.31 ± 0.01*,**

*Intragroup comparison at different time points with the data in the 2^nd week of modeling, significantly different, P < 0.05.

** Intragroup comparison with group N, significantly different, P < 0.05.

SD = standard deviation.
