A 42-Month Follow-Up of Double Root Fracture of a Lateral Mandibular Incisor

Abstract

This case report describes the treatment of a double root fracture of a lateral mandibular incisor and its follow-up over 3.5 years. The reason for the consultation was a tooth mobility following a fall that had occurred 2 days earlier. A test of pulp vitality for tooth 42 was positive. Periodontal probing at the level of the gingival sulcus confirmed the intactness of the epithelial attachment. Retro-alveolar radiographic examination revealed a double root fracture of tooth 42. A semi-rigid extra-coronal splinting was performed and a light grinding of the incisal edge of tooth 42 was then carried out in light of the dislocation of the coronal fragment, and the occlusion was checked with a strip of articulating paper. The outcomes at 6 months revealed that pulp vitality was still preserved, consolidation of the apical fracture had occurred, and the coronal root fracture was starting to heal. The 1-year, 2-year and 3-year follow ups revealed preserved pulp vitality, an absence of a fracture line in apical images, and no root resorption. This case report provides evidence for the preservation of vitality in the setting of a double root fracture.

Effect of two different materials in sealing vertical root fractures of intentional replantation on epithelial thickness of periradicular tissue

“…This fracture, which occurs not only in anterior but also in posterior teeth, causes loose or avulsed tooth. 1 Fracture of teeth can be categorized into vertical (longitudinal) and horizontal fractures. The majority of vertical fracture is caused by occlusal pressure and dental procedures.…”
