“…O en la resorción radicular inflamatoria (RRI), las raíces pueden parecer más cortas de lo que normalmente se espera y / o tener extremos de raíces irregulares, y tendrán radiolucencias apicales adyacentes al ápice radicular, aparecerá como muescas en forma de cráter en la superficie radicular radiopaca. 29,30 En cuanto a la realización de la endodoncia extrabucalmente Giannetti et al establecieron que el tratamiento de la avulsión dental; en un paciente con un tiempo extraoral mayor a una hora y con ápice maduro, será la terapia de endodoncia extraoral inmediata, ya que parece ser el método ideal para la eliminación de cualquier estímulo agitador.…”

“…Sin embargo, el 1% de NaOCl durante 15 minutos fue menos perjudicial para el cemento. 30 En Venezuela este manejo de la raíz es mucho más factible de realizar debido a que el Endogain no es fácil de adquirir. En el presente reporte de caso solo se lavó la raíz con hipoclorito al 5,25% y el alveolo con solución fisiológica antes de la reimplantación muy probablemente a esto se deba la reabsorción inflamatoria ya que no se eliminó completamente el tejido necrótico del ligamento periodontal.…”

La avulsión es el desplazamiento completo de la unidad dentaria (UD) fuera del alveolo, ocasionado por un traumatismo, sobre una estructura de soporte de alta resiliencia, provocando el desgarro de las fibras del ligamento periodontal (LPD), la cual debe ser reimplantada de inmediato, lamentablemente, esto no sucede en la mayoría de los casos. Los factores como; el medio de conservación y transporte, el tiempo transcurrido entre el momento de la avulsión y la reimplantación, el grado de maduración de la raíz, el tratamiento de la superficie radicular, la ferulización, la respuesta inmunológica del paciente y la destreza del operador influyen en el éxito de la reimplantación. Este reporte de caso analiza el manejo del incisivo central superior derecho en un paciente de 8 años de edad que sufrió la avulsión de la UD 11, conservado en agua y reimplantado tardíamente (42 horas). Se presentó una reabsorción radicular externa inflamatoria (RREI) como complicación, debido a mal pronóstico y condiciones previas. Sin embargo, el objetivo es restaurar, al menos temporalmente, la estética y la función manteniendo el contorno, el ancho y la altura del hueso alveolar. El diente se podrá extraer, si es necesario, tras una pronta evaluación interdisciplinaria.

“…NaClO is the most commonly used endodontic irrigation solution due to its tissue‐dissolving activity and bactericidal effects 21‐23 . Some studies showed that the use of NaClO solution effectively removed necrotic PDL and was more effective at protecting the cementum layer than mechanical removal by scraping the root surface 24 . In the present experiment, the pulp tissues were extirpated with an endodontic file, and the pulp debris and the periodontal ligaments were removed by being soaked in 1.5% NaClO for 15 min.…”

Alveolar ridge augmentation can be used to obtain appropriate alveolar ridge for dental implantation. A variety of bone graft materials including autogenous bone, allograft, xenograft, and alloplastic material are used in alveolar ridge augmentation. Autogenous tooth‐derived bone graft material has received much attention for the past few years, because the structure and physicochemical characteristics of tooth are similar to those of bones. Compared to autogenous tooth, allogenic tooth has the advantage of extensive resources. However, the problem of cell‐derived immunological rejection of allogenic tooth remains unresolved. In the present study, acellular tooth root (ATR) is obtained by an innovative combination procedure. The biocompatibility of ATR is assessed using cytotoxicity test, hemolysis test, intracutaneous reactivity test, and acute systemic toxicity test. Osseointegration is evaluated in vivo by implanting ATR into the rat tibia defect as an allograft material. The results show that the ATR has fine biocompatibility, and there is an osseointegration between ATR and bone bed at 8 weeks post operation. This study demonstrates that the ATR could be used in alveolar ridge augmentation as a kind of new tooth‐derived bone graft material.

“…In this study, 1 upper and 2 lower impacted wisdom teeth discarded as medical wastes were used as human TRC samples. The TRC surface was exposed by removing the remaining PDLs using sodium hypochlorite treatment, as described previously . Complete removal of PDLs without damage to the TRC surface was confirmed using optical microscopy of decalcified histological sections of separate sample pieces.…”

The periodontium supports the teeth by dentoalveolar fibrous joints that serve unique oral functions. Endogenous regeneration of the periodontium around artificial teeth (dental implants) provides a cost-effective solution for the extension of healthy life expectancy but remains a challenge in regenerative medicine. Biomimetics can create smart biomaterials that tune endogenous cells at a tissue–material interface. Here, we created a smart titanium nanosurface mimicking the surface nanotopography and micromechanical properties of the tooth root cementum (TRC), which is essential for the induction of dentoalveolar fibrous joints to regenerate the periodontium. After transplantation into the rat renal capsule, only the titanium artificial tooth with the TRC-mimetic nanosurface formed a complex dentoalveolar fibrous joint structure, with bone tissue, periodontal ligament (PDL), and TRC, in the decellularized jawbone matrix. TRC-mimetic titanium implants induce the formation of functional periodontium, even in a jawbone implantation model, which generally causes osseointegration (ankyloses). In human PDL cells, TRC analogousness in the surface mechanical microenvironment regulates matrix mineralization through bone sialoprotein expression and phosphorus metabolism, which are critical for cementogenesis. Therefore, the titanium nanosurfaces with nanotopographical and mechanical microenvironments mimicking the TRC surface induce dentoalveolar fibrous joints for periodontal regeneration by interfacial tuning of endogenous cells.

Chemical removal of necrotic periodontal ligament on delayed replanted teeth by sodium hypochlorite: morphological analysis and microhardness indentation test of cementum

Abstract: Use of either 1% NaOCl for 15 min or 5.25% NaOCl for 5 min was effective at removing necrotic PDL from the delayed replanted teeth whilst having a minimal influence on cementum integrity. However, 1% NaOCl for 15 min was less damaging to cementum.
