ABSTRACT
The aim of this study was to evaluate the influence of two dif-ferent irrigation protocols on artificial lateral root canalfilling capacity using different obturation techniques. Sixtysingle-root human teeth were used. Two artificial lateralcanals were created in the apical third. Root canals wereinstrumented up to a 45 K-file to the working length. Beforeeach file, root canals were irrigated either with 2 mL of 2.5%NaOCl or 2% chlorhexidine gel with further irrigation withsaline solution and 3 mL of 17% EDTA. Specimens were ran-domly divided into three groups according to the obturationtechnique (1) lateral compaction technique; (2) Taggerhybrid technique; and (3) thermoplasticized technique usingBeeFill 2 in 1. All groups used AH Plus as the root canal seal-er. The specimens were decalcified and cleared in methylsalicylate. The total length of lateral canals was observedunder X30 magnification with a stereomicroscope and meas-ured on the buccal and lingual root surfaces using Leica IM50software. The data were submitted to ANOVA and Tukey test(p<0.05). Among the obturation techniques, BeeFill 2 in 1showed deeper penetration into all lateral canals than the lat-eral compaction or Tagger hybrid techniques (p<0.05). Thelateral compaction group showed the worst results (p<0.05).Irrigants did not affect the outcome; there was no differencebetween NaOCl and chlorhexidine when the same obturationtechnique was used (p>0.05). Regardless of the irrigant usedduring endodontic procedures, the thermoplasticized tech-niques showed higher penetration behavior for filling artificiallateral canals than the lateral compaction technique.(AU)
RESUMO
O objetivo do presente estudo foi avaliar a influÛncia de doisdiferentes protocolos de irrigaþÒo na capacidade de penetraþÒode canais artificiais, utilizando diferente técnicas de obturaþÒo.Sessenta dentes humanos unirradiculares foram utilizados. Doiscanais laterais artificiais foram confeccionados no terþo apicaldo dente. Os canais foram instrumentados até uma lima K 45 nocomprimento de trabalho. Antes do uso de cada lima, os canaisradiculares foram irrigados com 2 mL de NaOCl 2.5% ou comClorexidina gel 2% seguido de soluþÒo salina. Ambos os gruposreceberam no final da instrumentaþÒo 3 mL de EDTA 17%. Osespecimes foram randomicamente separados em 3 subgrupos deacordo com a técnica de obturaþÒo utilizada (1) técnica de com-pactaþÒo lateral; (2) técnica híbrida de Tagger; e (3) técnicatermoplástica utilizando o BeeFill 2 em 1. Em todos os grupos ocimento utilizado foi o AH Plus. Depois, os elementos foramdiafanizados utilizando metil salicilato. As extens§es de pe -netraþÒo dos cimentos nos canais laterais foram realizadas uti-lizando estereomicroscópio (X30). Os dados de cada grupoforam analizados utilizando ANOVA e o teste de Tukey (p<0.05).Dentre as técnicas de obturaþÒo, a técnica termoplástica uti-lizando o BeeFill 2 em 1 mostrou a maior penetraþÒo em canaislaterais (p<0.05). A técnica de compactaþÒo lateral apresentouos piores resultados dentes os grupos testados (p<0.05). Os irri-gantes nÒo afetaram a penetraþÒo dos canais laterais; nÒo foramobservados diferenþas entre NaOCl e clorexidina, quando amesma técnica de obturaþÒo foi utilizada (p>0.05). Pode-se con-cluir que independente da substÔncia química auxiliar utilizada,as técnicas termoplásticas de obturaþÒo demonstraram maiorpenetraþÒo de canais laterais do que a técnica de compactaþÒo lateral.(AU)
