Summary

The objective of this study is to compare functional splinting time effect versus the suggested splinting time of (IADT) effect on tooth mobility and possible healing outcomes for surgically extruded permanent anterior teeth with crown root fracture.

Detailed description

Trauma involving the tooth supporting tissue, especially luxation injuries, is considered the most severe with consequences such as neurovascular disruption, pulp necrosis, and root resorption. Healing depends on factors such as the level of root development, the extent of damage to periodontal tissues, and the effects of bacterial contamination from the oral cavity . The course of healing of the severed periodontal ligament will determine the treatment outcome of these injured teeth .As a result, all treatment procedures are directed to minimize undesired consequences which might lead not only to loss of tooth, but also to loss of alveolar bone. The common treatment of luxated teeth is repositioning and splinting to achieve stability and to prevent further damage to the pulp and periodontal structures during healing. Splints should ensure adequate fixation, prevent accidental ingestion or inhalation, and should protect teeth against traumatic forces during the vulnerable healing period . The current guidelines for treatment of traumatic injuries by the International Association of Dental Traumatology (IADT) specify a short term functional splint for luxated teeth. However these protocols are based on clinical studies and animal experimentation employed rigid fixation techniques so the results of these investigations are not representative of the current protocols . Also splinting times in IADT guidelines are derived mainly from animal studies which considered of low quality evidence . As a result of, surgical tooth extrusion as treatment modality in cases of crown root fracture was chosen as a controlled traumatic injury to examine the true cause-effect relationship between splinting time and healing outcomes of periodontal ligament aiming to decrease the effect of bias, con-founders and probability of chance associated with the other types of luxation injury.
