Abstract(s)
A utilização de espigões em dentes tratados endodonticamente é um dos temas mais
estudados em Medicina Dentária. As opiniões são divergentes em relação aos
procedimentos clínicos e materiais a serem utilizados para a colocação e remoção de
espigões. O objetivo deste trabalho foi realizar uma revisão bibliográfica de forma a
organizar conceitos e princípios clínicos para melhor esclarecer os fatores que determinam
a necessidade de colocação, utilização e escolha do tipo de espigão, sua cimentação e
técnicas para a remoção. Foram analisadas as características e propriedades dos cimentos
de fosfato de zinco, ionômero de vidro, cimentos resinosos de polimerização química,
polimerização dupla, foto-polimerizável e os sistemas adesivos etch and rinse, self etch e
autoadesivos, bem como as técnicas para a remoção de espigões cimentados com diferentes
cimentos e sistemas adesivos para depois acessar o remanescente de guta percha para o
retratamento endodôntico. Foi feita uma pesquisa bibliográfica na base de dados electrónica
PubMed, Google Scholar e RCAAP com as seguintes palavras chave: “Espigões”;
“Retratamento Endodôntico”; “Ionómero de Vidro”; “Fosfato de Zinco”; “Cimentos
Resinosos”; “Posts”; “Endodontic Retreatment”; “Glass Ionomer”; Zinc-phosphate”;
“Resin Cements"; “Push Out Test”; “Posts AND Removal”. Concluiu-se que a cimentação
de espigões pré-fabricados de fibra de vidro com cimentos resinosos de dupla
polimerização associados aos sistemas adesivos self etch estão gradualmente substituindo
os outros tipos de espigões e demais cimentos e possibilitam restaurar o dente de forma
adequada e duradoura. E o uso de ultrassons apresenta maior eficácia e segurança na
remoção dos espigões.
The use of Posts in endodontically treated teeth is one of the most studied topics in dentistry. Opinions are divergent with respect to clinical procedures and materials to be used for placement and removal of Posts. The aim of this study was a literature review order to arrange concepts and clinical principles to clarify the factors that determine the need for placement, use and choose to Post type, your cementation and techniques for removal. The characteristics and properties of zinc phosphate cement, glass ionomer, resin cements chemical curing, dual curing, photo-curing and etch and rinse, self etch and self adhesive bonding agents were analyzed. Also, techniques for removing Posts cemented with different cements and adhesive systems and then access the remaining “gutta-percha” for the endodontic retreatment. A literature search was made in the electronic database PubMed, Google Scholar e RCAAP with the following keywords: “Espigões”; “Retratamento Endodôntico”; “Ionómero de Vidro”; “Fosfato de Zinco”; “Cimentos Resinosos”; “Posts”; “Endodontic Retreatment”; “Glass Ionomer”; Zinc-phosphate”; “Resin Cements"; “Push Out Test”; “Posts AND Removal”. It was concluded that the cement fiber Posts with resin cements dual curing associated with the self etch adhesive systems are gradually replacing other types of Posts and other cements and allow restoring the tooth proper and lasting manner. And the use of ultrasound is more effective and safe Posts removal.
