RESUMO

The effects of induced tooth movement on the pulp of Wistar rats were analyzed through light microscopy in 49 first upper molars. The orthodontic appliance consisted of a coil spring moving the fist left molar foreword supported by the incisor. The sample was divided into 4 groups according to the period of observation. the control group consisted of 10 animals without any orthodontic movement. the other 39 rats were evaluated after: 1, 2, 3, 4, 5, 6 and 7 days of dental movement. The efficiency of induced tooth movement was verified trough the expected classic periodontal phenomena, such as segmental hyalinization of the ligament, bone resorption and even dental resorption, due to intense forces on the distal root. the dentin-pulp complex did not demonstrate any morphological alteration which indicated effects of induced tooth movement.
