Objective:
To evaluate the clinical effect of sequential therapy for traumatized maxillary central incisor with horizontal mid-root fracture.
Methods:
Twenty maxillary central incisors with horizontal mid-root fracture following dental trauma were included in our study. The distance between root fracture plane and root apical segment was more than 5 mm. The sequential therapy included stabilizing the traumatized incisor with a flexible splint after repositioning the coronal segment of the tooth, temporarily filling with calcium hydroxide after root preparation, sealing the root apex with warm gutta-percha obturation technique and internal fixation with fiber post combined with composite resin adhesion. The patients were followed for 6 to 24 months.
Results:
Two cases healed without sign of fracture line and eighteen cases healed with sign of fracture line. No case failed. Abnormal mobility and translocation, percussion pain, gingival swelling, sinus tract and periodontal pocket were not observed in all the traumatized teeth.Radiology showed normal root apex and periodontium.
Conclusions:
Sequential therapy for maxillary central incisor with horizontal mid-root fracture could acquire a satisfactory therapeutic effect.
