Bruxism is nonfunctional clenching or grinding of the teeth. It is a destructive habit that may result in tooth wear. Although research on bruxism is extensive, its etiology remains debatable. The literature suggests that bruxism is correlated with both experienced and anticipated life stress. The purpose of this report is to describe 2 cases of severe bruxism in children of similar age with different life histories and to discuss the factors that could have triggered this parafunctional condition.
