The effect of traumatic dental occlusion on the degradation of periodontal bone in rats.

Context: A better understanding of the relation between traumatic dental occlusion and periodontal changes is needed.

Aims: This study aimed to evaluate the pattern of osteoclastic activity in the periodontal bone in front of the traumatic dental occlusion in rat molars.

Patients And Methods: Traumatic dental occlusion (TO) was induced in twenty rats, which were sacrificed after periods of 2, 5, 7, and 14 days.
