“…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).…”

“…Additionally, the EV has been shown to extrude less irrigant in the periapical tissues, thus reducing accidental extrusion of NaOCl (21). There is a scarcity of data evaluating debris removal with similar experimental protocols; therefore, the aim of this study was to evaluate smear layer removal and endodontic wall cleanliness after different irrigant activation regimens.…”

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.

“…Outra variável − o tipo e a profundidade de penetração da agulha de irrigação −, segundo alguns autores, influencia na limpeza e na extrusão apical do irrigante 3,14 . Tem sido relatado que as agulhas com abertura apical ocasionam mais extrusão quando comparadas às agulhas com abertura lateral 3,5,31 , o que pode ser explicado pela pressão mais elevada para o forame, discordando com estes resultados, em que não houve diferença estatística entre os dois tipos de agulhas avaliados.…”

“…É importante ressaltar que a ponta da agulha não deve se prender às paredes dentinárias durante a irrigação, devido ao risco de extravasamento ou extrusão da solução irrigadora para os tecidos periapicais 3,9,14,15 .…”

Influência do diâmetro foraminal do canal radicular, do tipo e da penetração de agulha, e do fluxo da solução irrigadora na limpeza e na extrusão apical Descritores: Endodontia; irrigantes do canal radicular; radiologia. Abstract Introduction:The root canal irrigation aims to clean and disinfect the root canal system, without causing apical extrusion. Objective: To evaluate the influence of apical foramen diameter, needle penetration depth and needle design, and the irrigating solution flow rate on the cleaning and apical extrusion. Material and method: Roots of human mandibular incisors with single-canal were instrumented and after enlarged with two different root apical sizes (40 and 60 K-files), the root canals were filled with contrast solution thickened with propylene glycol and zinc oxide. Two types of irrigation needles (27-gauge) with different designs (apical or lateral opening) were used, two flow rates corresponding to 15 or 25 mL/min and needle penetration at two depths (3 and 6 mm from the apex). Before and after irrigation, the teeth were radiographed using a digital radiographic system. Pre-irrigation (canals filled with contrast) and post-irrigation (canals with remaining contrast) images were submitted to digital subtraction using the Adobe Photoshop CS4 software and the areas were measured using the Image Tool 3.0 software, obtaining the percentage of cleaning and extrusion. Data obtained were subjected to one-way ANOVA and Tukey's tests with the significance level of 5%. Result: There was no statistical difference between the apical foramen diameter, needle penetration depth and needle design, and the irrigating solution flow rate on the cleaning results (more than 97%) and the level of apical extrusion (less than 0.38 mm 2 ), (p>0,05). Conclusion: All irrigation protocols evaluated provided cleaning of the root canal and low apical extrusion of irrigating solution.
