Abstract
Root canal filling is one of the stages of endodontic treatment that deserves special attention, being responsible for the final sealing, avoiding recontamination and reinfection in that space. The objective of this research was to evaluate in vitro the influence of three endodontic filling techniques in the filling of simulated lateral canals, these being the Lateral Condensation Technique, Continuous Wave Technique and Hybrid Tagger Technique. Thirty lower premolar teeth were used, which were divided into three groups (n = 10) for comparisons of filling techniques. The chemical-mechanical preparation was carried out with Protaper Universal rotary files, then lateral canals at the apical, medium and cervical level were made with an LN drill. The teeth were filled and evaluated with digital radiography considering the amount of simulated canals that were filled by the filling material. The results were subjected to statistical analysis using the non-parametric Chi-square test, in which a statistical difference was considered when p <0.05. The lateral condensation technique showed the lowest results with a statistically significant difference (p <0.05), when compared to the Tagger hybrid and continuous wave, however there was no statistical difference between the Tagger hybrid technique and continuous wave (p> 0.05). It was concluded that none of the three techniques was able to fill all the simulated lateral channels. The continuous wave technique presented the largest amount of pre-filled lateral canals, followed by the Tagger hybrid technique and lateral condensation.
