1/28. replantation of avulsed teeth: considerations and complications.Avulsion of teeth is a traumatic dental injury which can be managed by replantation. Important considerations for successful replantations are highlighted. Several sequelae to replantation are discussed in relation to the clinical features observed in a patient seen 6 years after replantation of two avulsed upper incisors. Many of these complications might have been avoided if the patient had returned to the clinic for root canal therapy shortly after the teeth was replanted.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/28. Management of an avulsed primary incisor.The case describes the management of an avulsed maxillary central primary incisor of a 3 1/2-year-old girl. The tooth was retained in the oral cavity for 30 min. After replantation it was splinted for 17 days. At day 11 the root canal was completely instrumented and obturated with a calcium hydroxide paste. The 1-year follow-up documented no pathologic clinical or radiographic findings. One and a half years after the trauma the tooth was extracted since a fistula and extensive external inflammatory resorption had developed. The permanent successor erupted along with its neighboring central incisor without any complications 6 months later. Conventional approaches for treating avulsed permanent teeth could also be applied to avulsed primary incisors to preserve them for a certain period without the additional risk of damaging their developing permanent successors.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
3/28. Contemporary treatment of the resorbed avulsed tooth: a case report.This report describes the treatment sequence after traumatic loss of a maxillary central incisor in a 15-year-old patient. Following extraoral root canal treatment and initially successful replantation, the case presented 9 years later with complete root resorption. After augmentation with an autologous mandibular corticocancellous graft, a dental implant was placed in a second stage surgery. The case highlights the challenge facing clinicians in providing the appropriate standard of care for today's treatment options.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
4/28. A case report of a vital replanted tooth with unfavourable extra-alveolar condition: a 10-year follow-up.This case report describes the survival of a maxillary left central incisor after an avulsion injury under unfavourable extra-alveolar condition, when the patient was 9 years old. At subsequent clinical follow-ups, the tooth maintained vitality 10 years after the injury. There was sign of gradual obliteration of the root canal space. Concomitantly, the replanted tooth manifested typical characteristics of ankylosis with minimally detectable resorption complication.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
5/28. Conservative treatment of severely luxated maxillary primary central incisors: case report.The treatment and follow-up evaluation of two orally luxated maxillary primary central incisors in a three-year-old girl is described. The injured teeth were displaced into a cross-bite with their mandibular opposing teeth. They were repositioned shortly after the injury and splinted with composite resin for two weeks. oral hygiene instructions and antibiotic therapy were prescribed. Two weeks after the injury a necrotic pulp was removed and the root canals filled with a resorbable paste. Thirty months after the injury, the teeth and the surrounding tissues were clinically and radiographically asymptomatic and physiologic root resorption could be noted. The permanent successors erupted soon after natural exfoliation of the injured primary teeth. Only mild hypocalcified defects were observed on the permanent incisors.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
6/28. Bone-like tissue growth in the root canal of immature permanent teeth after traumatic injuries.Following a severe traumatic incident to permanent immature teeth, the growth of calcified tissue in the pulp space may occasionally occur. This calcified tissue may be diffuse or in intimate contact with the dentine. It has been suggested that a wide open apex, severe damage to the root sheath, and the absence of infection are only some of the predisposing factors leading to this metaplasia of pulp tissue into bone-like tissue. Five cases are described.- - - - - - - - - - ranking = 4keywords = canal (Clic here for more details about this article) |
7/28. Investigations on a cell culture medium for storage and transportation of avulsed teeth.Non-physiologic storage of avulsed teeth leads to a high incidence of root resorption, resulting in poor prognosis. This study investigated the suitability of specially composed cell culture media for storage of extracted teeth for up to 48 hours. Autoradiographic investigations revealed that the proliferative activity of periodontal ligament (PDL) cells of teeth stored in cell culture medium for up to 48 hours increased with storage time. Studies on proliferation of PDL cells after storage of teeth in different media for up to 24 hours demonstrated that the proliferative activity is dependent on the composition of the medium. Immunohistochemical investigations with markers for cell proliferation revealed that pulp cells of extracted immature teeth show numerous proliferations after storage for up to 24 hours in a special cell culture medium but few proliferations after storage in Hanks Balanced Salt Solution (HBSS). The investigations indicate that a special cell culture medium can preserve cell viability of PDL cells adhering to extracted teeth for at least 48 hours. The in vitro results are confirmed by a case presented: After storage of two upper central incisors for 36 hours in the cell culture medium the teeth could be successfully reimplanted after extraoral insertion of titanium posts into the root canal (auto-alloplastic reimplantation). Clinical and radiological follow-up examinations for 12 months revealed normal periodontal healing.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
8/28. Conservative management of an intruded immature maxillary permanent central incisor with healing complication of pulp bone.Traumatic intrusion injury of permanent teeth is serious with multiple complications possible associated with the pulp, periodontal ligament, alveolar bone and Hertwig's epithelial root sheath. The optimal treatment for the management of an intrusion injury has not yet been determined. A case is presented involving the conservative management of an immature maxillary permanent central incisor intrusively luxated by allowing for re-eruption and orthodontic extrusion two weeks later. After a follow-up period of ten months, the intruded tooth continued to show a mobility of grade one, without metallic percussion tone or infra-occlusion, which confirmed periodontal ligament healing. Although the intruded tooth failed to respond to dry ice testing, no other signs of pulp necrosis were evident and the colour of the intruded tooth was within normal limits throughout the follow-up period. However, complications of healing of Hertwig's epithelial root sheath occurred, causing in-growth of bone and periodontal ligament into the root canal.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
9/28. Laser Doppler flowmetry for monitoring traumatized teeth.Laser Doppler Flowmetry (LDF) has been shown to be valuable in monitoring revascularization of immature incisors following severe dental trauma. Several investigators have demonstrated the ability of LDF to record blood flow signals from vital tooth pulps. In this case report, LDF was used for a 7-year-old child patient following a severe luxation of tooth #9. During follow-up examinations the traumatized tooth was unresponsive to traditional vitality testing during the first 6 months; however, LDF indicated that revascularization had occurred much sooner. Until recently, CO2 ice has been the most effective method for sensitivity testing in trauma cases such as presented here. In this case, LDF gave us the assurance that we could defer invasive care during a critical time period when root canal therapy might have been initiated for this child patient.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
10/28. Obliteration of pulp canal space after concussion and subluxation: endodontic considerations.Concussion and subluxation injuries to permanent teeth lead to obliteration of the pulp canal space in 3% to 11% of cases, depending on the severity of the injury and the developmental stage of the tooth. Obliteration of the pulp canal space may make root canal treatment necessary because of the development of apical periodontitis or for cosmetic reasons. If carefully executed, root canal treatment in teeth with an obliterated pulp canal space is highly successful and may act as a basis for internal bleaching.- - - - - - - - - - ranking = 9keywords = canal (Clic here for more details about this article) |
