ABSTRACT
Bruxism is nonfunctional clenching or grinding of the teeth. It is a destructive habit that may result in tooth wear. Althoughresearch 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.

Case 1
A 6-year-old boy was brought to the pediatric dental clinic by his mother. On history, his mother revealed that he gnashed his teeth at night, but she could not tell for how long this had been going on. The child’s medical history showed chronic respiratoryproblems, due to allergy, and an absence of gastroesophageal reflux. No previous dental treatment was reported. Ingestion of acid drinks or medication was denied. Although the mother described the child as highly excitable, during the consultation he was extremely shy and introspective. His mother reported that they lived in a violent area, where shootings frequently occurred and that her child...
