The effect of physiological root resorption on the histological structure of primary tooth pulp.

The aim of this study was to determine, the effect of physiological root resorption on the histological structure of healthy primary tooth pulp. Fourteen canine teeth, which needed to be extracted for orthodontic purposes and in which resorption had just begun (1st group, resorption did not exceed 1/3 of root length) or was in advanced resorption stage (2nd group, resorption was between 1/2 and 2/3 of root length), were used for this study. After the extraction of the teeth, they were prepared for histological examination. Then the samples were examined using light microscopy. The result no difference was found which could be detected by polarized light microscope that was related to physiological resorption and histological structure of primary teeth pulp.
