“…The pulp healing rate in this study is higher than those reported by Rhouma et al 20 and Wang et al 21 of 7.0% and 9.1%, respectively. However, this can be considered as a lower rate than that reported in previous studies, which reported pulp healing rates ranging from 18% to 34.8% 18,19,22–25 .…”

“…While the first implies pulp survival with neural and vascular repair and the completion of root development, intracanal bone-like tissue is characterized by the presence of mineralized tissue inside the root canal space which is separated from the internal root surface together with the cessation of further root development. 26 The pulp healing rate in this study is higher than those reported by Rhouma et al 20 and Wang et al 21 of 7.0% and 9.1%, respectively.…”

“…3,12,[14][15][16][17] The available clinical data regarding pulp responses after permanent teeth replantation have demonstrated pulp healing rates in immature teeth that range from 7% to 41%. [18][19][20][21][22][23][24][25][26][27] Two distinct radiographic healing patterns have been described: hard tissue deposition on the dentinal walls followed by narrowing of the pulp lumen and completion of root development, and hard tissue formation in the pulp lumen that is separated from the dentinal walls but in continuity with the periapical bone with arrested root development. 18,24,26,27 However, sound information about the prognostic factors that lead to pulp healing that may influence the type of healing remains scant.…”

Background/Aim Tooth displacement during avulsion causes total rupture of the pulp's neurovascular supply. Revascularization and pulp healing may occur in immature teeth, which gives rise to the recommendation that root canal treatment may not be required. The aim of this study was to evaluate the prognostic factors for the pulp’s response after replantation of young permanent teeth. Methods Records from 117 patients with 133 replanted permanent immature teeth were reviewed, and pulp outcomes were classified as healing (hard tissue deposition on the dentinal walls followed by narrowing of the pulp lumen or ingrowth of bone‐like tissue inside the pulp canal) or non‐healing (pulp necrosis with infection). The effect of clinical and demographic co‐variates on the hazards of both outcomes was assessed performing a competing risk model. Results Pulp necrosis with infection was diagnosed in 78.2% of the teeth, and healing was observed in 12.8% of the teeth. A total of 12 teeth (9.0%) were censored due to prophylactic removal of the pulp or severe external root resorption caused by eruption of adjacent canines. The cs‐Cox model demonstrated that the hazards of pulp healing increased in teeth with extra‐alveolar periods <15 min (csHR: 7.83, 95% CI 1.76–34.80, p = .01), while the hazards of pulp necrosis with infection decreased (csHR: 0.31, 95% CI: 0.10–0.92, p = .04). Teeth replanted with Moorrees’ stages 4 and 5 of root development had higher hazards of pulp necrosis with infection than teeth with stage 2 of root development (csHR: 2.23, 95% CI 1.11–4.50, p = .03; csHR: 2.89, 95% CI: 1.40–5.95; p = .01). Conclusions Pulp healing rarely occurred after replantation of young permanent teeth being associated with short extra‐alveolar periods <15 min. Early stages of root development decreased the hazards of pulp necrosis with infection.

“…The treatment was considered successful according to the following criteria: 1. patient without spontaneous pain; 2. color of the gingival was normal, no sinus tract; 3. no sensitive to percussion; 4. no loosening of the teeth or loosening at the Degree I; 4. radiological analysis demonstrated that radiolucent shadow around apex dispeared and there is no internal root resorption and external root resorption should be no more than 2 cm [17].…”

Objective To evaluated the outcomes of the teeth avulsed from alveolar bone in accidents for a 1 year follow up when endodontic root canal therapy was performed at different time points. Materials and Methods According to the inclusion criteria, 109 patients diagnosed with teeth avulsion due to accidents were enrolled at base-line and 103 patients finally completed follow-up in this trial. 115 teeth were firstly assigned to two groups according to storage condition. Then they were randomly assigned to one of two groups respectively. The teeth were treated with root canal therapy at different stages. All of patients were recalled at baseline, in the first, third month, sixth month and first year (end of follow-up) for clinical and radiological evaluation. Results 103 patients finally completed follow-up in this trial. As for periodontal healing, cases with before-replantation treatment were significantly more than post-replantation treatment in dry storage. On the contrary, more periodontal healing cases were obtained in ideal storage. In the first year after treatment, there was no difference of success rate between G21 and G22 (P < 0.05). Significant difference was found between G11 and G12 (P < 0.05). Conclusion In clinical practice, root canal therapy should be performed prior to replantation in dry storage condition for more than 60 minutes. In contrast, if not, root canal therapy could be postponed.

“…En las ultimas radiografías presentadas en caso abordado se logra apreciar mejor la leve reabsorción radicular externa (figuras 2c y 2d) la cual puede guardar una relación con el almacenamiento en medio seco según varias investigaciones 8,17,18 , en especial la de Rhouma, McMahon y Welbury 17 en Escocia donde de 16 dientes que se mantuvieron en un medio seco solo 6 de ellos pudieron continuar con su función en boca y no fracasaron después del reimplante, resultado que se soporta con un OR de 4,13 (IC 95% 1,33 -12,80). No obstante, en el presente reporte la reabsorción observada no comprometió la permanencia del diente en la arcada superior, desenlace que podría deberse a la inmersión del diente en fluoruro de sodio, tal y como lo reportan varias investigaciones en animales [19][20][21] .…”

RESUMENLa avulsión dentaria es el resultado más severo y con peor pronóstico de los traumatismos dento-alveolares. El reimplante dentario constituye un desafío para el odontólogo, debido a la exigencia del manejo y el seguimiento estricto a los protocolos que pueden determinar un resultado exitoso a largo plazo. En este reporte de caso se presenta el seguimiento clínico y radiográfico durante 5 años, de un reimplante dental tardío de un incisivo central superior a las 7 horas después de su avulsión, en un adolescente de 16 años de edad, proveniente de Bucaramanga. La evolución del caso mostró un estado favorable a pesar de las condiciones limitadas de tiempo y conservación de la pieza dentaria.Palabras clave: Avulsión de diente, reimplante dental, reporte de caso. ABSTRACTThe most severe dento-alveolar trauma is dental avulsion, its forecast is questionable in many cases. Dental reimplantation is a challenge for the dentist, due to the strict management and strict fulfilment of protocols that can determine a successful long-term outcome. This case report shows a 5-years clinical and radiographic follow-up of an avulsed right maxillary central incisor reimplanted 7 hours later in a 16-year-old teenager from Bucaramanga. The evolution of the case showed a positive status in spite of the limited conditions of time and conservation of the tooth.
