Repair characteristics of horizontal root fracture: a case report

Abstract  – Radicular fractures in permanent teeth are uncommon injuries among dental traumas, comprising 0.5–7% of the cases. Fracture occurs most often in the middle-third of the root and rarely at the apical-third. The present paper reports a clinical case of a horizontal radicular fracture located between the middle- and apical-third of a upper left-central incisor followed-up for over 3 years. The tooth was extracted owing to periodontal reasons. Histomorphologically, it showed pulp-vitality preservation and root healing by hard-tissue deposition.     

Conservative treatment of a cervical horizontal root fracture and a complicated crown fracture: a case report

Abstract This case report describes successful long-term conservative management of a cervical root fracture and a complicated crown fracture of the maxillary central incisors in a 12-year-old patient. A mineral trioxide aggregate partial pulpotomy was performed on the maxillary right central incisor, while the maxillary left central incisor was splinted to the neighbouring lateral incisor using an acid-etch technique. Both teeth remained asymptomatic throughout the 3.5 years of a review period, with the cervical root fracture having mostly healed with the formation of a calcified tissue between the fragments. Two different treatment methods were used for two different injuries that resulted in pulp preservation in both cases. This in turn has provided for normal root development to occur while also allowing for preservation of bone.     

Repair of untreated horizontal root fractures: two case reports

Abstract – Intra-alveolar root fractures of incisor teeth are more frequent than other dental injuries. These case reports describe two untreated horizontal root fractures of the maxillary right central incisors. Patients reported accidental trauma, which occurred several years ago. These fractures were discovered during a routine full-mouth radiographic survey. Teeth were asymptomatic and tested vital to electric pulp tests     

Repair of untreated root fracture: a case report

Abstract A case is presented in which an untreated root fracture in a maxillary central incisor of an adult male was found radiographically 10 years after injury. The tooth was removed and the area of the root corresponding to the fracture line was examined by SEM while the remaining tooth was processed for decalcified sections. Calcification of the coronal pulp associated with extensive tissue atrophy and normal pulp tissue apically was observed. Two barriers composed of dent in al and cemental hard tissue were present apically in the coronal fragment and in the fracture line.     

Maxillary molar root fracture caused by sinus surgery: case report

Abstract A case is presented in which a horizontal root fracture of the mesiobuccal root of a maxillary first molar was diagnosed as the source of a patient's chronic pain. Horizontal root fractures arc rare in posterior teeth. The source of the fracture was determined to be trauma from access or curettage during two Caldwell-Luc sinus procedures. A detailed history and endodontic retreatment led to the diagnosis. A mesiobuccal root resection resolved the chronic pain.     

Severe lateral luxation and root fracture: report of a case with 5-year follow-up

Abstract— A case of severe lateral luxation and root fracture in upper incisors is reported. Treatment involved the repositioning and fixation of the injured teeth and endodontic treatment with calcium hydroxide. The importance of long-term follow-up is emphasized.     

Repair of untreated horizontal root fracture: a case report

Abstract  – We report a clinical case of horizontal root fracture in the mandibular first premolar induced by a traffic accident. The fractured tooth spontaneously healed and diagnosed radiographically after 2 years. Fractured fragments were separated by a narrow radiolucent line and the edges were rounded, and healing of the tooth is likely to be related to interproximal connective tissue healing. Our case is an example of spontaneously healed fracture roots. An interesting finding is that the healing was observed even in the presence of two root canals, the vitality of the pulp was preserved and displacement of fragments were prevented.     

Successful minimally invasive intervention in a primary central incisor after root fracture: A case report

Root fractures vary in severity, extent, and location, according to the physical and mechanical aspects of the accident. Root fractures are rare in primary teeth and they affect dentin, cementum, periodontal ligament and the pulp. This paper reports a case of a two-and-a-half-year-old baby who had a root fracture of the upper right primary central incisor (tooth 51) as a consequence of trauma that was managed with minimally invasive intervention. After clinical and radiographic examinations, the presence of tooth mobility, pain, bleeding and a horizontal apical root fracture was diagnosed on tooth 51. The treatment of choice was splinting for 120 days, which can deliver excellent results regardless of the patient's age. The tooth was preserved without needing endodontic intervention until its physiologic exfoliation and normal eruption of its permanent successor. As sequelae to the fractured tooth 51, there was some coronal color alteration and dystrophic calcification of the root canal. This tooth did not develop ankylosis or mobility during the follow-up period. After 57 months of follow-up, repositioning and splinting were appropriate ways to manage this horizontal root fracture in the apical third of this primary tooth. It allowed the tooth to be preserved in the arch with normal function.     

Treatment of traumatized permanent incisors with crown and root fractures: a case report

Abstract – A case report of the treatment of permanent incisors with crown and root fractures is presented. A radiolucent lesion at the fracture lines was treated with calcium hydroxide in the coronal fragments for 18 months. Clinically, the teeth became firm and the radiographic results after 2 years showed healing of the lesion and hard tissue filling in the space at the fracture lines.     

Treatment of a vertical root fracture

Abstract— This case report presents the successful non-surgical treatment of a vertically fractured tooth by cementation with adhesive resin.     

Rapid orthodontic extrusion of crown root and cervical root fractured teeth

Abstract This study concerns the relapse tendency and extent of root resorption in 33 extruded non-vital crown root fractured or cervical root fractured teeth in 32 patients 10–20 years old. They constitute all orthodontically extruded teeth at the Orthodontic or Pedodontic Departments, Eastman Institutet, Stockholm (1982–1987). A simple extrusion mechanism exerted a force of 60–70 p along the root axis of the tooth. An extrusion of 2–3 mm was obtained in most patients; the most extreme effect was 6 mm. In 16 patients the extrusion was achieved within 3 weeks, in 12 it lasted for 4–6 weeks and in 5, 7–9 weeks. The treatment was more complicated in the lower jaw. After the extrusion, a fibrotomy was done and in most patients also a gingival recon–touring to create an optimal relation between the gingiva and the margin of the restoration. Periodically identical radiographs were taken immediately before and after the extrusion, after 3 months and after 1 year. A minor relapse, about 0.5 mm, was observed in 3 patients. Limited root resorption was found in 6 teeth and severe in only 1. The resorptions did not progress in the following 2 years of observation.     

Concomitant intrusive luxation and root fracture of a central incisor - report of a case

Abstract A case of a 9-year-old boy who presented with intruded maxillary central incisors, one of which had also sustained a middle third root fracture, is reported. The root fracture was diagnosed after orthodontic extrusion was started, which resulted in separation of the apical and coronal fragments. The hypermobile coronal fragment was stabilised by passing a K file through a palatal access cavity into the root canal of the apical fragment. Orthodontic alignment was completed and the fractured incisors were restored with the file left in situ. At a 10-year follow-up, the incisors were clinically healthy and continued to satisfy aesthetic and functional demands.     

Spontaneously healed horizontal root fracture in maxillary first premolar: report of a case

Abstract –  Root fractures of the posterior teeth are rare and occur as a result of severe trauma. This study describes the horizontal root fracture of a maxillary first premolar. The fractured roots were discovered during a routine radiographic examination. The tooth was asymptomatic and responded positively to electric pulp testing. The patient reported accidental trauma, which occurred 14 years before. Our case is an example of spontaneously healed fractured roots. The interesting findings were that the healing was observed even in the presence of two roots, including preservation of the vitality of the pulp.     

Different clinical outcomes following root fractures of adjacent incisors: a case report

AIM: To report different patterns of root fracture healing in adjacent maxillary central incisors with distinct post-treatment outcomes. SUMMARY: To describe the case of a 12-year-old girl who presented with an avulsed coronal fragment of tooth 11 and root fractures in the middle thirds of teeth 11 and 21. Four months after initial treatment, she was referred for specialized endodontic care. Tooth 11 presented no clinical or radiographic signs of pulp breakdown. However a sinus tract was found related to the middle root third of tooth 21, indicating pulp necrosis in the coronal fragment. The coronal fragment was root filled and periapical surgery was performed to remove the apical fragment. Twelve months after the clinical procedures and 16 months after trauma, hard tissue healing was evident in tooth 11 region. Bone healing was also satisfactory in the periapical region of tooth 21. *Even adjacent teeth may display different reaction patterns after trauma. *The prognosis of root fractures is variable and different clinical approach may be required to preserve teeth with fractured roots.     

Root ZX根尖定位仪诊断牙根横折的实验研究

目的研究Root ZX根尖定位仪是否能准确诊断牙根横折的存在。方法将20颗离体单根管上前牙形成牙根横折,用Root ZX根尖定位仪分别测量横折断端不分离、横折断端分离但断端内无印模材料、横折断端分离且断端内有印模材料3种情况下的根管长度,并与实际根管长度进行比较。结果在横折断端不分离、横折断端分离但断端内无印模材料2种情况下,根尖定位仪不能探测到横折位置;在横折断端分离且断端内有印模材料情况下,电测根管长度在横折冠段实际根管长度±0.5 mm范围内为100%,可探测到横折位置。结论Root ZX根尖定位仪对没有软组织长入的牙根横折无诊断价值,但对有软组织长入的牙根横折有很好的准确性。     

Multidisciplinary approach to the immediate esthetic repair and long-term treatment of an oblique crown–root fracture

Abstract –  This case report describes the esthetic management of a dental trauma at the first visit and its subsequent treatments to restore the esthetics and function. Today, patients expect adequate esthetics and the ability to confidently smile immediately after the first appointment. In addition, they require that esthetics is maintained throughout the definitive treatment phase as well. After the use of the fractured crown as a temporary replacement crown, an orthodontic extrusion was undertaken to restore the physiological periodontal attachment. The tooth was then splinted for 6 months and at completion of this orthodontic stage, the permanent restoration was fabricated.     

Spontaneously healed root fracture: report of a case

Abstract  – Blows to the facial region can cause root fractures especially in anterior teeth. Fractures below the alveolar crest have a very high potential for healing and treatment consists of reduction and rigid splinting immediately after trauma. The aim of the treatment is to obtain reunion of the fragments. Although the fracture can heal spontaneously, the prognosis will not be as good as the correctly treated ones. The purpose of this paper is to report a case of spontaneously healed root fracture.     

Multidisciplinary approach for the treatment of an oblique root fracture: a case report

Abstract –  This clinical case study describes a multidisciplinary modified technique for the treatment of an oblique root fracture. A-38-year old woman with a history of trauma and a broken tooth was referred to our clinic. There was an oblique crown fracture extending the coronal third of the root just underneath the cingulum of the crown. The patient was willing to keep her tooth in function by any means. Two weeks after root canal therapy the flap was raised. The coronal two third of the root canal was enlarged. An impression of the enlarged root canal and tooth surface with surrounding bone was taken. The flap was sutured and the impression was sent to the laboratory for the post-casting preparation. After 7 days, the flap was opened again and casting was cemented. The flap was sutured. Ten days after the second surgery, three anterior teeth were prepared and a final impression was taken for the preparation of porcelain crowns. Restoration was finished 15 days after the second operation. The patient is still under maintenance therapy and the 12 month results are presented in this report. Extraction may not be the only alternative for the root fractures. Even for fractures under the alveolar margin, alternative multidisciplinary approaches can be used to restore and allow the tooth to survive.     

Multidisciplinary treatment approach for crown fracture and crown-root fracture – a case report

Abstract –  The increased incidence of traumatic injuries to anterior teeth is a consequence of leisure activities, where the most common injuries are crown fractures. Treatment of the dental trauma is complex and requires a comprehensive and accurate diagnostic and treatment plan. It is also important to consider the biological, functional, esthetic and economic aspects, as well as the patient's desire. The purpose of this article is to report a case that shows the multidisciplinary approach required to successfully manage the rehabilitation of a maxillary central incisor with a complex crown fracture and a maxillary lateral incisor, that at first presented an oblique crown-root fracture, and after the orthodontic extrusion, suffered a more apical new crown-root fracture.
