Dynamics of dentoalveolar ankylosis and associated root resorption
Dental Traumatology, 1989
Hammarstrom L, Blomlof L, Lindskog S. Dynamics of dentoalveolar ankylosis and associated root resorption. Endod Dent Traumatol 1989; 5: 163-175. Abstract -The present experimental studies in monkeys were undertaken to study the initiation and progression of dentoalveolar ankylosis of replanted teeth and associated root resorption. Maxillary and mandibular lateral incisors were extracted and replanted after an extraoral period of 15 min or 1 h. Teeth with an extraoral period of 1 h were endodontically treated. Half the number of monkeys were given antibiotics at the time of replantation. The observation periods varied from 2 days to 40 weeks. Irrespective of the length of the extraoral period, initial root resorption and minor areas of ankylosis were found 1 week after replantation. The initial ankylosis was not preceded by root resorption. In teeth replanted after an extraoral period of 15 min the ankylotic area did not increase with increasing time after replantation. Instead the periodontal membrane was re-established, separating the root surface from the alveolar bone. In teeth replanted after an extraoral period of 1 h, the initial ankylotic area increased with increasing time after replantation. Eight weeks and more after replantation, most of the periodontal membrane was replaced by bone covered by osteoblasts and occasional osteoblasts that were in continuity with the endosteal cells outlining the marrow spaces of the alveolar bone. The cementum and dentin were then gradually resorbed with increasing time after replantation. Antibiotics given at the time of replantation reduced the initial inflammation in the periodontal membrane and the inflammatory root resorption after all observation periods and it also seemed to some extent to prevent bacteria from entering the necrotic pulp tissue. Based on the present results it is suggested that root resorption associated with dentoalveolar ankylosis is initiated by endosteal osteoblasts and is thus a hormonally regulated process. This is in contrast to inflammatory root resorption, which seems to be triggered by inflammatory cells.

External root resorption (ERR) is a serious complication after replantation, and its progressive inflammatory and replacement forms are significant causes of tooth loss. This retrospective study aimed to evaluate the factors related to the occurrence of inflammatory ERR (IERR) and replacement ERR (RERR) shortly after permanent tooth replantation in patients treated at the Dental Trauma Clinic at the School of Dentistry, Federal University of Minas Gerais, Belo Horizonte, Brazil. Case records and radiographs of 165 patients were evaluated for the presence, type, and extension of ERR and its association with age and factors related to the management and acute treatment of the avulsed tooth by using the logistic regression model. The patient's age at the moment of trauma had a marked effect on the ERR prevalence and extension. The patients older than 16 years at the moment of trauma had less chance of developing IERR and RERR (77% and 87%, respectively) before the pulp extirpation,...

Aim: The complication in delayed replantation is root resorption that leads to loss of reimplanted teeth. This study was designed to evaluate the influence of stem cells from human exfoliated deciduous teeth (SHEDs) on the healing process of periodontal tissues after delayed tooth replantation in rats. Material and Methods: Forty-five rats had their right upper incisor extracted and maintained in dry storage for 60 minutes. Then dental papilla was removed; root canal was prepared and filled with calcium hydroxide paste and root surface treatment was processed. Rats were randomly assigned into three groups: Control group: the incisor was replanted without any substance in the dental socket. SHEDs group: the tooth was replanted after infusion of SHED, re-suspended in platelet-rich-fibrin in the dental socket; platelet-rich-fibrin group: the incisor was replanted with platelet-rich-fibrin in the dental socket. Animals were euthanized on days 15, 30 and 60 after replantation; histological and histomorphometric analyses were performed. Results: Root resorption was present in all experimental groups. No statistically significant differences were observed in the final period of study. The control group showed more replacement resorption but SHEDs group, showed dental tissues were more preserved. Inflammatory resorption nearly did not affect any group, as expected in this protocol (p<0.005). Conclusions: The findings of this study suggest that in the SHEDs group, teeth were more preserved with ankyloses occurrence, witch holds teeth in the socket for a longer period of time, when compared to replacement resorption or inflammatory resorption in the healing process of delayed replantation.
Causes of primary tooth avulsion and replantation treatment
International Journal Of Community Medicine And Public Health, 2021
During primary dentition, the etiology changes by age group. For instance, traumas secondary to collisions and falls are attributable to early movement within the first six years, while accidents secondary to frequent playing are the main reason within the following nine years, and violence is the most common etiology until the age of 25 years old. Previous studies have estimated that traumas from falls, sporting activities, bicycling, traffic accidents, and violence were the most common causes of dental injuries in children. Iatrogenic causes also contribute to 0.04-12% of dental injuries, including avulsions. According to the current evidence, whether to use reimplantation or not is still controversial and further investigations are needed. Among the various case reports, damage to the permanent successors, root resorption, clot formation, and pulp necrosis were documented as potential complications and adverse events with intended reimplantation. However, many techniques were rep...
Dental Avulsion- Immediate Replantation: 8- Year Follow UP Case
IOSR Journal of Dental and Medical Sciences, 2016
Avulsion of permanent front teeth is a rare accident, mostly affecting children between seven and nine years of age. Replanted and splinted, these teeth often develop inflammation, severe resorption or ankylosis affecting alveolar bone development and have to be extracted sooner or later. This report proposes a discussion on the various peculiarities of a tooth avulsion case with immediate replantation, such as a long retention period, root canal filling with MTA, orthodontic treatment .
Multidisciplinary treatment of avulsed teeth case report and 6 years follow-up
Journal of Pediatric Dentistry, 2016
One of the most seen complications after replantation in avulsed teeth is root resorption. [2,10,11] Root resorptions are seen in about 50-76% of the cases and they are considered to be associated with storage conditions of the tooth and the period of tooth staying out of alveolar socket. [4,10,12,13] As a result of long-term storage of a tooth in nonphysiological conditions, periodontal ligamentum necrosis, and replacement resorption is inevitable. [2,4,7,12] Alveolar bone formation after periodontal tissue necrosis and root resorption results in ankylosis (replacement resorption). Ankylosis in young individuals may cause infraocclusion due to continuing growth. [4,11,13] In case, there is infected

Objectives: According to the studies, the best time for endodontic treatment after accidental replan-tation is no more than two weeks. Unlike cases of tooth trauma, in autotransplantation, all the manipulations flow under relatively sterile conditions and the likelihood of pulp infection is minimal. We decided to check out the resorption rate in case of different terms of pulp extirpation and whether revascularization is possible with a favorable healing course. Material and Methods: In this study we performed the autologous transplantation of closed-apex third molars in 52 adult patients, divided in 3 groups. In the 1 st group (8 cases) the pulp extirpation was done before the surgery, in the 2 nd group it was performed in 2 weeks after the surgery (33 cases). In the 3 rd group there was no treatment at all (11 cases). Results: Results were evaluated after 3, 6, 12, 24 months by clinical and radio-graphic examination. The survival rate and the pulp condition of the transplanted teeth was observed. The dynamic periotestometry examination was performed in order to track the resorptive processes. For statistical data processing we used the Mann-Whitney test. Conclusions. No dependence of the development of inflammatory and replacement resorption on the time of pulp extirpation was evaluated. During this observation period direct confirmation of revascularization has not been obtained. Despite possible pulp necrosis inside the transplanted tooth, the risk of inflammatory resorption is minimal in the absence of
