Thirty extracted single-rooted human teeth were selected, the coronal portion was removed, and the working length was established 1 mm short of the foramen. Two lateral canals were created, one in the middle third and one at the apical third, in each root canal. After chemo-mechanical preparation by the manual instrumentation through step-back technique, the teeth were divided into 3 groups (n = 10) according to the filling technique used: G1 – lateral condensation; G2 – Tagger hybrid technique; G3 – single cone technique. In all groups gutta-percha cones and zinc oxide and eugenol-based sealer were used. After seven days of storage, postoperative radiographs were taken and the images were projected for evaluation of the quality of lateral canal filling. Data were submitted to statistical analysis by Kruskal Wallis test at 5% significance level. The results showed that Tagger hybrid technique filled 35% of simulated lateral canals, followed by lateral condensation (30%) and single cone technique (25%). However, statistical analysis revealed no statistically significant difference in the ability to fill lateral canals among the groups (p>0.05). Although the Tagger hybrid technique associated with endodontic sealer presented a higher incidence to fill lateral canals, the other techniques also had the ability to provide the sealing of lateral canals.\u00a0 Descriptors: Endodontics, root canal filling materials. Resumo Este estudo teve como objetivo avaliar, \u00a0in vitro, a capacidade de diferentes t\u00e9cnicas de obtura\u00e7\u00e3o no preenchimento de canais laterais artificiais em dentes extra\u00eddos usando recurso de imagem. Trinta dentes humanos extra\u00eddos (unirradiculares) foram selecionados, a por\u00e7\u00e3o coron\u00e1ria foi removida e o comprimento de trabalho foi determinado 1 mm aqu\u00e9m do forame apical. Dois canais laterais foram criados, um no ter\u00e7o m\u00e9dio e um ter\u00e7o apical, em cada raiz. Ap\u00f3s o preparo qu\u00edmico-mec\u00e2nico utilizando t\u00e9cnica escalonada com limas manuais, os dentes foram divididos em 3 grupos (n=10) de acordo com a t\u00e9cnica de obtura\u00e7\u00e3o utilizada: G1- condensa\u00e7\u00e3o lateral; G2- t\u00e9cnica h\u00edbrida de Tagger e G3- t\u00e9cnica do cone \u00fanico. Em todos os grupos foram utilizados cones de guta-percha e cimento \u00e0 base de \u00f3xido de zinco e eugenol. Ap\u00f3s sete dias de armazenamento, radiografias p\u00f3s-operat\u00f3rias foram realizadas e as imagens foram projetadas para avalia\u00e7\u00e3o da qualidade da obtura\u00e7\u00e3o dos canais laterais.

A t\u00e9cnica h\u00edbrida de Tagger preencheu 35% dos canais laterais simulados, seguida pela t\u00e9cnica da condensa\u00e7\u00e3o lateral (30%) e pela t\u00e9cnica do cone \u00fanico (25%). No entanto, a an\u00e1lise estat\u00edstica n\u00e3o revelou nenhuma diferen\u00e7a significativa na capacidade para preencher os canais laterais entre os grupos (p> 0,05). Embora a t\u00e9cnica h\u00edbrida de Tagger associada ao cimento endod\u00f4ntico tenha apresentado uma incid\u00eancia maior de preenchimento de canais laterais, as outras t\u00e9cnicas tamb\u00e9m apresentaram capacidade de proporcionar o selamento dos canais laterais simulados.\u00a0 Descritores: Endodontia, obtura\u00e7\u00e3o do canal radicular. 1 Acad\u00eamica \u2013 UPF. 2 Prof. \u2013 UPF. 3 Universidade de Passo Fundo.
