| Outline of Final Research Achievements |
This study revealed that root size and PDL structure may be reduced due to disuse atrophy resulting from a defect in occlusal function, but may be recovered following a gain of occlusal stimuli. It was also suggested that occlusal stimuli regulate PDL area through expression of VEGF and bFGF in rat PDL. Furthermore, the present study suggested that the application of the orthodontic force to hypofinctional tooth occur more severe root resorption than functional tooth. It was emphasized that root resorption may be prevented by its recovery of occusal function which stimulates the periodontal tissues.
