Tooth loss following surgical extrusion of crown-root fractured teeth: A 6-years survival analysis

Aim: This study aimed to show the adverse effect of surgical extrusion technique in the management of crown-root fractures regarding tooth loss over a six-year follow-up period.
Methods: Twenty patients with a crown-root fracture in maxillary incisors were selected from an 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 recalled every year following surgical extrusion to assess the risk of tooth loss.
Results: Twenty patients participated in this study with mean age of 131 months. Only
17 patients completed a follow-up period of at least one year. Overall, five teeth were lost over a follow-up period of six years constituting 29% (95% CI 13 to 53%) of the study population.
Conclusion: Surgical tooth extrusion could be considered as a treatment option for crown-root fractures. Nevertheless, tooth loss is not an uncommon adverse effect. The first two years are critical for deciding the survival of surgical extruded tooth.
