Electron microscopic quantitations of feline primary and permanent incisor innervation.

摘要: Abstract Axons from pulps of fully developed primary and permanent teeth were processed for electron microscopy, counted measured cross-sectional area circumference. These measurements totalled each specimen experimental groups compared statistically. Permanent contained a significantly greater myelinated unmyelinated innervation. However, higher proportion axons. Considering the tooth weight as an indication amount tissue innervated, no significant differences found in innervation between teeth. Therefore, density appears same, while relative proportions fibre types are not. Fibre-size analyses suggested that axons more irregular shape. It is concluded exist patterns may be relevant to sensitivity. A positive linear correlation was amounts This suggests predictability quantities easily determined quantities.
