Abstract

Pulp vitality may occasionally change while tooth experiencing orthodontic movement, and orthodontists are the particular group who concern this phenomenon if it happens. The respiration rate of dental pulp will be depressed inevitably in short term when tooth is subject to orthodontic force. If force level is extreme, circulatory interruption can occur and further induce pulp necrosis. When orthodontic movement on pulpalcompromised teeth (e.g. teeth with trauma history or large restorations) is required, the pulp response to orthodontic force should be monitored. This article provides an overall review on the pulpal reactions during orthodontic movement and dental movement on teeth with previous endodontic treatment.
