– The fine structure of peripheral root dentin in the cervical, midroot and apical areas has been studied by light and electron microscopy. Both methods have shown that the peripheral dentin at these three levels contains very few dentinal tubules. Further pulpally, dentinal tubules with a narrow lumen and highly mineralized peritubular areas were noted. In the cervical and middle part of the root a few small unmineralized areas were sometimes noted close to the cementodentinal junction, while in the apical part unmineralized areas were more numerous. Dentinal tubules were sometimes seen penetrating these areas. The unmineralized areas contained collagen fibers and had the shape of small interglobular areas.
