## Distance

distance in depth between servicemen, guns, vehicles, and subunits or units (ships) when formed in ranks, on the march (cruise), or in combat formation and also between aircraft when flying in formation or in a combat formation.

## Distance

an important geometric concept whose meaning depends on the kind of entities for which it is defined. The distance between two points is the length of the line segment joining the points. The distance from a point to a line or a plane is the length of the perpendicular from this point to the line or plane. The distance between two parallel lines or planes is the length of a common perpendicular to the lines or planes. The distance between two nonintersecting nonparallel lines in space is equal to the distance between the parallel planes in which the lines lie—that is, the length of the line segment that joins the lines and is perpendicular to both.

[′dis·təns]
(mathematics)
A nonnegative number associated with pairs of geometric objects.
The spatial separation of two points, measured by the length of a hypothetical line joining them.
For two parallel lines, two skew lines, or two parallel planes, the length of a line joining the two objects and perpendicular to both.
For a point and a line or plane, the length of the perpendicular from the point to the line or plane.
(mechanics)
The spatial separation of two points, measured by the length of a hypothetical line joining them.

There was no significance regarding the VC, MPT /s/, and MPT /e/ measures and age among voice professionals when compared to the group that did not use their voice professionally, neither when compared to the FD and OFD groups (Table 3).
Still, there are studies about subjects of both genders with OFD [17,27] that verified a reduction in MPT and VC, partially converging with the results.
This work verified that, as the MPT /e/ value increased, the MPT/s/ value also increased, as well as the VC and vice-versa in both FD and OFD groups, demonstrating the interrelation among these variables.
There was no difference among the variables professional voice use, age, and FD or OFD diagnosis relative to MPT /e/, MPT /s/, and VC.
In addition, there were no significant differences in the histological signs of inflammation, quality and maturity of newly formed bone in the 1-wall intrabony defects between the ABB + CM and OFD groups [Table 2].
These approaches lead to a more predictable periodontal regeneration as compared to periodontal OFD only.
In this study, the 1-wall intrabony defect model was evaluated in beagles and the histological observations are consistent with most findings reported elsewhere.[sup][9],[17] In most reports, the formation of new bone and cementum formation did not exceed 30–35% of the height of 1-wall intrabony defects in dogs with OFD group over an 8-week healing interval.[sup][15],[18] However, in the study, alveolar bone and cementum formation almost reached 64–79% of the height of defect and 33–41% bone area formation (not including the residual ABB granules) in the ABB + CM groups.
