“…Nevertheless, the EA system showed similar results, if compared with the EV system, regarding the degree of cleanliness at 3, 5, and 8 mm from the apex. This may be explained by the fact that the EA tip activated NaOCl only and it was positioned at 2 mm from the apex, whereas the microcannula of the EV reached the WL, ensuring the irrigating solutions (both NaOCl and EDTA) were refreshed and eliminating the vapor lock at the apex as confirmed by other studies (20,21).…”

Introduction: The purpose of this study was to evaluate the effectiveness of different irrigating methods in removing the smear layer at 1, 3, 5, and 8 mm from the apex of endodontic canals. Methods: Sixty-five extracted single-rooted human mandibular premolars were decoronated to a standardized length of 16 mm. Specimens were shaped to ProTaper F4 (Dentsply Maillefer, Ballaigues, Switzerland) and irrigated with 5.25% NaOCl at 37 C. Teeth were divided into 5 groups (2 control groups [n = 10] and 3 test groups [n = 15]) according to the final irrigant activation/delivering technique (ie, sonic irrigation, passive ultrasonic irrigation [PUI], or apical negative pressure). Root canals were then split longitudinally and observed by field emission scanning electron microscopy. The presence of debris and a smear layer at 1, 3, 5, and 8 mm from the apex was evaluated. Scores were analyzed by KruskalWallis and Mann-Whitney U tests. Results: The EndoActivator System (Dentsply Tulsa Dental Specialties, Tulsa, OK) was significantly more efficient than PUI and the control groups in removing the smear layer at 3, 5, and 8 mm from the apex. The EndoVac System (Discus Dental, Culver City, CA) removed statistically significantly more smear layer than all groups at 1, 3, 5, and 8 mm from the apex. At 5 and 8 mm from the apex, PUI and the EndoVac did not differ statistically significantly, but both performed statistically better than the control groups. Conclusions: In our study, none of the activation/delivery systems completely removed the smear layer from the endodontic dentine walls; nevertheless, the EndoActivator and EndoVac showed the best results at 3, 5, and 8 mm (EndoActivator) and 1, 3, 5, and 8 mm (EndoVac) from the apex.

“…The EV has been shown to introduce a higher flow of irrigant and produce better debridement compared with that achieved by needle irrigation (20). Additionally, the EV has been shown to extrude less irrigant in the periapical tissues, thus reducing accidental extrusion of NaOCl (21).…”

“…Estes detritos, por razões físicas, mecânicas e anatômicas, tendem a se acumular em maior quantidade na porção apical dos condutos, como mostraram diversos trabalhos aqui revisados (Holland et al, 1990;Lopes et al, 1996;Ciucchi et al, 1989;Khademi;Feizianfard 2004;Nielsen;Baumgartner, 2007).…”

“…Ao inverter o fluxo, o sistema gera uma pressão negativa que faz com que a solução irrigadora faça um caminho inverso, com condições de alcançar e limpar até os limites do comprimento de trabalho sem pressão e com baixo risco de extravasamento (Nielsen;Baumgartner, 2007;Schoeffel, 2007;Schoeffel, 2008a,b;Schoeffel, 2009 .…”

“…Diversos autores compararam a remoção de debris obtida com o sistema EndoVac e outros dispositivos auxiliares na irrigação e aspiração (Nielsen;Baumgartner, 2007;Heilborn et al, 2010;Parente et al, 2010;Abarajithan et al, 2011;Saber;Hashem, 2011;Howard et al, 2011;Ribeiro et al, 2012 (Pecora et al, 1991;Tasman et al, 2000;Teixeira et al, 2005;Giardino et al, 2006;Huang et al, 2008). O volume total utilizado com o sistema EndoVac é maior do que o utilizado com irrigação convencional dentro do mesmo período de tempo (Nielsen;Baumgartner, 2007;Kurtzman, 2009;Brunson et al, 2010) e poderia ter favorecido os resultados deste sistema caso este cuidado não fosse tomado.…”

"O conhecimento científico é cumulativo, dependente do desenvolvimento de novas tecnologias e idéias. Nossas verdades permanecem verdadeiras até que alguém demonstre que elas são incompletas. No mínimo, esta perspectiva deveria nos ensinar a defender nossas verdades temporárias com a humildade de quem aprende com o passado." The present study aimed to analyze in vivo the effectiveness of root canal preparation on bacterial reduction in patients's teeth with primary apical periodontitis. Marcelo Gleiser RESUMOSamples were collected from 20 patients before (S1) and after (S2) preparation with ProTaper rotary files, varying only the technique used for irrigation and aspiration:Group A (conventional irrigation -n = 10) and Group B (with the aid of EndoVac system -n = 10). After extraction, the DNA present in the samples was quantified by real-time PCR with the SYBR Green method, identifying the number of 16SrRNA gene copies. In all samples, except for a post-preparation case with EndoVac, copies of the target gene were identified. Average for all cases was 1,6 X 10 8 and 8,8 X 10 5 copies of the 16SrRNA, before and after preparation, respectively. For the groups separately, the same values were 2,0 X 10 8 and 5,5 X 10 5 (conventional) and 1,1 X 10 8 and 1,2 X 10 6 (EndoVac). The mean percentage of reduction was 97.52% (97.02% for the conventional and 98.04% for the EndoVac). The Mann-Whitney test concluded that both techniques significantly reduced the microrganisms after preparation (p<0,0001), with no differences between them (p=0,9705). None of the techniques were effective in the complete elimination of bacteria under this methodology. The antibacterial efficacy of the EndoVac system under this methodology was similar to that obtained with conventional irrigation and aspiration.
