Abstract

Root resorption is a condition that can occur as a result of dental trauma. The factors that must be taken into account to prevent this complication depend on the type of injury suffered by the tooth. Injuries associated with an increased risk of root resorption are those which cause a dislocation of the root (luxations, avulsions and root fractures with displacement of the coronal fragments). The therapeutic measures aimed to address this type of injury can be grouped into three types: repositioning the tooth to its physiological position in the alveolus, splinting and treatment of pulp necrosis. The immediate reposition of a tooth or a displaced fragment is one of the most crucial aspects to prevent resorption. Once the tooth is correctly repositioned, a semi-rigid splinting is the most recommended type of splint to prevent resorption. Special attention must be also taken to the possible pulp necrosis that is often associated to these injuries. The early extirpation of necrotic tissue before allowing contamination is the indicated treatment to avoid inflammatory root resorption.
