“…Clinical examination of root fractures should evaluate tooth color, sensitivity to percussion, mobility, and sensitivity to thermal stimulation (4). In our study, both cases showed slight mobility (grade 1), which can be explained by the cervical location of the fracture line, on at least one side of the root (7).…”

Spontaneous healing responses detected by cone-beam computed tomography of horizontal root fractures: a report of two cases

et al. 2014

Horizontal root fractures (HRF) usually affect the anterior teeth as a result of trauma, and generally heal spontaneously, depending on the vitality of the pulp. Diagnosis based on clinical findings, sensitivity tests, and radiographic examination is important to determine the presence of a root fracture and to prevent a root fracture from passing unnoticed. Cone-beam computed tomography (CBCT) has been used successfully for diagnosis and prognosis imaging of root fractures and has proved to be superior to other radiographic methods. This study reports two cases of dental trauma caused by a collision and a sports accident. The patients suffered horizontal root fractures in the maxillary left central incisor and in the mandibular left central incisor. The diagnosis of root fracture was confirmed by cone-beam computed tomography (CBCT) images, which also demonstrated spontaneous healing of the fracture line. The repair occurred by interposition of connective tissue in the former case and by interposition of bone and connective tissue in the latter case. The final diagnoses of both cases were based on CBCT images, indicating the importance of a CBCT examination to reach a firm diagnosis and to follow the healing process of root fracture cases, avoiding unnecessary radical endodontic treatment.

“…The upper central incisors are most often affected by horizontal root fractures (HRF), followed by the upper lateral incisors, as a result of trauma associated with accidents, sports injuries, or fights . Only 5% of root fractures occur in lower incisors . Diagnosis of HRF must be based on clinical findings, sensitivity tests, and radiographic examination.…”

“…Reduction of the fragments and maintaining them in their original position allows the fracture to consolidate by formation of a callus that resembles dentin on the pulp side and that resembles dental cement on the periodontal ligament side. This healing, which is common in case of immature teeth and when the associated periodontal trauma is minimal, varies from 2-3 months in the best cases (1,13,14). The immobilisation splint is kept in place for 4-12 weeks if movement of the coronal segment persists upon removal of the restraint, and another immobilisation will have to occur for a longer period of time (5,11).…”

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.

“…Root fractures are defined as fractures that involve dentin, cementum and the pulp, resulting in stretching or laceration of the pulp and/or periodontal ligament injury (rupture or compression) [4]. Root fractures are relatively rare trauma, comprising from 0.5% to 7.0% of injuries in permanent dentition [5]. Immature teeth with vital pulps rarely sustain horizontal root fractures [6].…”

Treatment of horizontal root-fractured maxillary incisors

et al. 2019

Root fractures are defined as fractures that involve the dentin, cementum, and pulp, resulting in stretching or laceration of the pulp and/or periodontal ligament injury (rupture or compression). Two cases of horizontal root-fractured maxillary incisors are introduced in the present report. The first case is a middle third root-fractured maxillary incisor with root canal therapy in the coronal fragment, and the second case is a cervical third root-fractured maxillary incisor without root canal therapy. Both cases showed favorable results with a long-term follow-up period. In all traumatic injuries, early diagnosis and appropriate intervention dramatically enhance the outcome. The primary purpose of the treatment of root-fractured teeth is to maintain the vitality of the teeth. After an adequate observation period, if vitality control reveals non-vital pulp tissue, or if the patient complains of pain or discomfort in the tooth, endodontic therapy can be performed, usually to the coronal segment only.
