Abstract
Although the relations between periodontal issues and other physical disease have been reported, significant relations among periodontal disease, malocclusion and orthodontic treatment have not been reported. However, orthodontic treatment creates pockets, causing gingival recession as well as bone loss. Especially, in adult orthodontic treatment we must consider the periodontal tissue. It has been considered that occlusal problem would not cause periodontal disease, but mesial inclined teeth tends to cause plaques to the mesial site, forming pockets, eventually leading the bone loss. We concluded that what we conduct orthodontic treatment, we must be careful of the periodontal tissues, in order to avoid the bone loss, attachment loss, or formation of periodontal pocket.
