Abstract

The aim of this study is to elucidate the root resorption of primary canines in relation to the development of successive permanent teeth and the change in the internal structure of the surrounding area. We observed the mandibles of the dry skulls of Indian children, using Micro-CT, and measured distance between the root surface of the primary canine and the bony crypt of canine. The bony crypts including successive canines were located immediately below the primary canine roots in the primary dentition stage. When the first molars reached the alveolar crest in addition to the primary dentition, the bony crypts moved in the distolingual direction, and showed inferior growth, resulting in compact bone resorption of the mandibular base. Root resorption of primary canines was observed on the distolingual surface with the advancing of the developing stages. After the central incisors reached the alveolar crest, it was quantitatively shown that the distance between the lingual surface of primary canine roots and canine bony crypts reduced.
