Table 5. Morphological analysis of mandibular incisors in WT and Rsk2-/Y mice.

		Li (mm)	hi (mm)	Hi (mm)	li (mm)	ti (mm)	lpa (mm2)
WT	Mean	11.33	1.11	2.96	9.38	0.65	10.36
	STD	2.34	0.07	0.20	1.56	0.02	1.07
Rsk2-/Y	Mean	11.29	1.14	2.97	9.05	0.65	10.18
	STD	1.66	0.05	0.21	1.65	0.03	1.33

No statistically significant differences were revealed between right and left incisors in both groups (p>0.05). As a consequence, results from right and left incisors were merged. No statistical difference was observed between WT and Rsk2-/Y (p>0.05).

(Li) length of the longest and external bow, (hi) height of median part of the incisor, (Hi) total height of the incisor, (li) horizontal length of the incisor joining the tip to the distal extremity of the root, (lpa) projected area in lateral view of the incisor, (ti) thickness the median part of the incisor. For more explanations on the measured distances, see Figure S3. STD : standard deviation.
