RESUMEN
Lesão perirradicular é uma doença de etiologia microbiana, cuja evolução possui forte relação com a resposta imunológica do hospedeiro, que ocorre no intuito de conter essa infecção. O tratamento endodôntico nesses casos tem como objetivo biológico final a desinfecção do sistema de canais radiculares para possibilitar o reparo da região periapical. Esse reparo é um processo complexo que consiste em hemostasia, inflamação, proliferação celular, maturação e remodelação. Diversos estudos vêm sendo realizados no intuito de relacionar fatores sistêmicos ou hábitos adquiridos com o desenvolvimento, diagnóstico, severidade e cura das lesões perirradiculares. Essas condições são referidas como modificadores da doença e podem esclarecer o surgimento de sintomatologia dolorosa em casos assintomáticos, a cura tardia de algumas lesões, e explicar o porquê alguns canais adequadamente tratados resultam em fracasso. As doenças hereditárias de coagulação causam alterações na hemostasia dos portadores, gerando propensão para sangramento abundante e modificações importantes na cicatrização de feridas. Essa revisão bibliográfica identificou as associações existentes entre os transtornos hereditários de coagulação mais comuns (hemofilias A e B e doença de von Willebrand) e o reparo de lesões endodônticas e concluiu que tal condição clínica pode afetar as respostas imunes, interferindo no reparo perirradicular.
Periradicular injury is a disease of microbial etiology, whose evolution has a strong relationship with the host's immune response, which occurs in order to contain this infection. The endodontic treatment in these cases has the ultimate biological objective of disinfecting the root canal system to enable repair of the periapical region. This repair is a complex process consisting of hemostasis, inflammation, cell proliferation, maturation and remodeling. Several studies have been carried out in order to relate systemic factors or acquired habits with the development, diagnosis, severity and cure of periradicular lesions. These conditions are referred to as disease modifiers and can clarify the onset of painful symptoms in asymptomatic cases, delayed healing of some lesions, and explain why some properly treated channels result in failure. Hereditary coagulation diseases cause changes in patients' hemostasis, generating a propensity for heavy bleeding and important changes in wound healing. This bibliographic review sought to identify the associations between the most common hereditary coagulation disorders (Hemophilia A and B and von Willebrand's disease) and the repair of endodontic lesions and concluded that such a clinical condition can affect immune responses, interfering with periradicular repair.
RESUMEN
Radiolucent or hypodense lesions in the crown of unerupted teeth may be due to pre-eruptive intracoronal resorption. Clinicians must be aware of this risk so that they can diagnose and appropriately treat this condition. The purpose of this study is to present a well-documented clinical case of pre-eruptive intracoronal resorption in an impacted third upper left molar of a 63 year old female patient. This was an unexpected finding, which occurred after cone-beam computed tomography was used to investigate the first upper left molar, which had an acute periradicular abscess. A multidisciplinary team followed up the case to describe clinical, radiographic and histological findings. The available treatment options were discussed, and the tooth extraction was the option chosen. Previous case studies describing such resorption in third upper molars have not been reported. This case shows that all permanent teeth in a pre-eruptive stage must be analysed radiographically to detect early pre-eruptive intracoronal resorption.
