Avaliação microbiológica de cones de guta-percha: estudo in vitro

Abstract: A maior causa da necessidade de retratamento endodôntico é a resistência microbiana ao preparo químico-mecânico e aos materiais obturadores. Sendo importante avaliar o padrão de desinfecção dos cones de guta-percha utilizadas na obturação endodôntica, para que se obtenha a máxima desinfecção durante o tratamento. O objetivo do presente trabalho foi verificar a desinfecção dos cones de guta-percha utilizados na obturação endodôntica através de um estudo in vitro. Para tal, utilizou-se a seguinte metodologia: a … Show more

“…As the gutta-percha cones are the main filling materials and are in constant contact with the periapex, it is crucial that the cones be free of microorganisms in order for the endodontic treatment to be satisfactory 14,15 . Some authors 10,16 , when studying guttapercha cones immediately after they were removed, with sterile clinical tweezers from their respective sealed packages, observed that these materials may be contaminated from the factory. However, in the present study, no microbial growth was observed during the analysis of cones that were immediately removed from the sealed package.…”

“…A radiopacidade de um cimento endodôntico é frequentemente discutida, sendo uma característica que contribui para o sucesso do tratamento endodôntico. Cimentos que exibem pouca radiopacidade podem dificultar a visualização do selamento e até mesmo de extravasamentos, podendo ser detectado falhas no selamento radicular (Lopes, 2010;Guedes et al, 2021). Outro aspecto importante se deve ao fato de que em áreas com o istmo, canais acessórios e laterais, as quais não podem ser preenchidos por guta-percha, a radiopacidade do cimento obturador, ajuda a observar se houve um bom vedamento nessas regiões (Andinós et al, 2011;Fonseca et al, 2017).…”
