External Root Resorption Management of an Avulsed and Reimplanted Central Incisor: A Case Report

Abstract

Background: Avulsion and reimplantation of permanent teeth represent a major challenge in terms of treatment and long-term prognosis. The present study reported clinical management of external root resorption of an avulsed and reimplanted maxillary central incisor. Case report: A 9-year-old boy reported an uncomplicated crown fracture and avulsion of tooth 11 and complicated crown fracture of tooth 21 due to trauma. Reimplantation of element 11 was obtained within 30 min post-trauma and 3 days after both elements were diagnosed with necrotic pulp. In addition, tooth 11 showed early external root resorption. Both elements underwent endodontic treatment and root closure with apical plug using calcium-silicate-based cement. At 6-month follow-up root resorption appeared to be arrested. Twenty-four months after trauma the clinical results were stable, although signs and symptoms of ankylosis were observed. Conclusions: An immediate endodontic approach and use of calcium-silicate-based cement seemed to contrast the progression of root resorption of an avulsed and reimplanted central incisor after 24 months of follow-up.

Biomechanical Behavior Evaluation of a Novel Hybrid Occlusal Splint-Mouthguard for Contact Sports: 3D-FEA

“…Several physical activities present a possible risk of maxillofacial injuries due to (1) falls and (2) collisions with other players, hard surfaces, and solid objects [ 23 , 24 , 25 ]. Although the importance of wearing a mouthguard is paramount as a preventive measure, the athlete does not always wear it, or wears it improperly [ 24 , 25 , 26 ].…”

“…Several physical activities present a possible risk of maxillofacial injuries due to (1) falls and (2) collisions with other players, hard surfaces, and solid objects [ 23 , 24 , 25 ]. Although the importance of wearing a mouthguard is paramount as a preventive measure, the athlete does not always wear it, or wears it improperly [ 24 , 25 , 26 ]. Usually, the most common reasons for not wearing a mouthguard are discomfort and difficulty with breathing, talking, and swallowing, during an activity [ 24 , 27 , 28 , 29 , 30 ].…”

Management of External Inflammatory Root Resorption following Tooth Autotransplantation Using a Modified Combination of Triple Antibiotics

“…Most often, the phenomenon initially reveals itself with small-sized lesions of cementum within PDL and, if not treated, may progress towards the involvement of the dental pulp [ 5 ]. Traumatic injuries, replantation of avulsed teeth, intentional (auto)replantation, and autogenous tooth transplantation are amongst factors that could initiate EIRR [ 6 ]. Since EIRR is a deteriorating lesion and could end in the gradual destruction of dental structure and subsequent tooth loss [ 7 ], it should be immediately diagnosed, properly managed, and perfectly treated.…”

“…A recent study has claimed that regenerative endodontic procedures (REPs) can be elaborated as a potential solution for the treatment of EIRR; however, REPs are not contemplated as the first treatment option and need further clinical trials [ 9 ]. Nonetheless, it has been shown that immediate endodontic treatment and removal of microorganisms accompanied by the application of a suitable calcium silicate-based biomaterial could arrest and contrast the advancement of root resorption in reimplanted and avulsed teeth [ 6 ].…”
