Aim: To show the effectiveness of surgical extrusion technique in management of crown-root fractures.Methods: Twenty patients with crown-root fracture in maxillary incisors were selected from outpatient clinic in pediatric dentistry department- Cairo University. Twelve males and eight females with age range from 11-14 years participated in this study. Surgical extrusion was performed combined with endodontic treatment. Patients were evaluated using cone beam computed tomography (CBCT) and periotest. Contra-lateral teeth were taken as controls. Possible side effects that were investigated are; ankylosis, increased tooth mobility, root resorption, and possibility of tooth loss.Results: Twenty patients participated in this study with mean age of 131 month. Only 17 patients completed a follow-up period of at least 1 year. Mean follow-up period for all patients was 16 month. No ankylosis occurred in any of the extruded teeth. Four teeth showed root resorption; one showed progressive inflammatory root resorption with subsequent tooth loss, while the other three teeth showed non-progressive surface resorption. Periotest values of surgical extruded teeth showed statistical significant increase than control teeth by mean of 3.5(±5.3) PTV in the horizontal directions and a mean of 2.5(±3.8) PTV in the vertical directions. 2/20 teeth were lost constituting 10% (95% CI 3 to 30%) of study population.Conclusion: Surgical tooth extrusion is a reliable method in management of crown-root fractures. Surface root resorption is the most common side-effect associated with the procedure. Surgical extruded teeth don’t suffer ankylosis as a side effect. Although surgical extruded teeth possess increased tooth mobility in comparison to their counterparts, this increase is considered of minimal clinical importance.
