Morphometric analysis relations to mandibular canal (MC) visibility scoring

MC part for visibility evaluation	JDS part for morphometric analysis
	H-AC-MC	H-MC	H-AC-IB
Distal superior	1 [12.8 (0.9)] and 4 [15.2 (0.6)] (p = 0.01), 3 [10.2 (0.4)] and 4 [15.2 (0.6)] (p = 0.04)	1 [2.4 (0.1)] and 3 [1.7(0.1)] (p = 0.04), 3 [1.7 (0.1)] and 4 [2.4 (0.1)] (p = 0.04)	1 [22.2 (0.7)] and 4 [24.2 (0.6)] (p = 0.04)
Distal inferior	4 [13.3 (1.0)] and 5 [14.6 (0.6)] (p = 0.04)	–a	–a

JDS, jaw dental segment.

MC part for visibility evaluation: JDS MC visibility evaluation in distal superior and distal inferior part (in visibility scores: 1, 2, 3, 4, 5); JDS part for morphometric analysis: JDS measurement part for morphometric analysis {measurement values are presented as mean [standard error (SE)] in millimetres}: H-AC-MC, the height from the alveolar crest to the MC dark ribbon; H-MC, the height of the MC; H-AC-IB, the height of the mandible.

Statistically significant differences are presented: “visibility score [morphometric analysis value (SE)]” and “visibility score [morphometric analysis value (SE)]” “(p-value)”.

^a“–” indicates no statistically significant difference (p > 0.05).
