“…The use of the rotary instrument associated with the EndoVac, EndoActivator, and PUI improved the removal of Ca(OH) 2 resulting in cleaner root canals. Nevertheless, none of the techniques completely removed the Ca(OH) 2 from the root canal, and this is in agreement with previous studies that found residues of this medication in the root canal, irrespective of the use of different irrigation/agitation systems of irrigants and devices, such as laser, for example (Van der Sluis et al, 2007;Kuga et al, 2010;Silva et al, 2011;Tasdemir et al, 2011;Wiseman et al, 2011;Kaptan et al, 2012;Goode et al, 2013). Thus, future researches must be conducted, using other techniques for Ca(OH) 2 removal from the root canal.…”

Calcium hydroxide [Ca(OH)2 ] residues in root canals may compromise sealing of filling and endodontic treatment success. The aim of this study was to compare the efficacy of using rotary instrument associated with EndoActivator, EndoVac, passive ultrasonic irrigation (PUI), and conventional needle irrigation (CNI), in Ca(OH)2 removal from root canal, by means of scanning electron microscopy (SEM) images. Sixty-six human canines were prepared with the Protaper system up to F5 and filled with Ca(OH)2 . After 7 days, Ca(OH)2 was removed with rotary instrument F5 associated with the irrigation techniques used in each group (n = 15): GI (CNI), GII (EndoVac), GIII (EndoActivator) and GIV (PUI). In all groups 15 mL of 2.5% NaOCl and 3 mL of 17% EDTA were used for Ca(OH)2 removal. The Ca(OH)2 residues was evaluated by SEM in the middle and apical third using a system of scores. The results were analyzed by the Kruskal-Wallis and Dunn tests (α = 0.05). None of the techniques completely removed the Ca(OH)2 from root canals. There was no difference between EndoActivator, EndoVac and PUI (P > 0.05), but the three techniques removed more Ca(OH)2 than the CNI (P < 0,05), in the middle and apical thirds of the root canal. It was concluded that the rotary instrument combined with EndoActivator, EndoVac, and PUI was shown to be more efficient than the rotary instrument combined with the CNI in removing Ca(OH)2 from the root canal.

“…1), and 115 studies were off topic. Reasons for exclusion were the following: studies assessing irrigating solutions (14,(16)(17)(18)(19)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53), no apical third evaluation (21,31,(54)(55)(56)(57)(58)(59), no ultrasonically activated irrigation (10-12, 20, 25, 28-30, 60-74), no extracted human adult teeth (75)(76)(77), evaluated under the scanning electron microscopy (39)(40)(41), and case reports (13). Full texts of 62 potential studies were assessed.…”

“…[17] This is in agreement with previous studies. [1819] The crudest of the irrigation techniques–conventional syringe irrigation–remains the most commonly practiced method of irrigation due to its simplicity, easy control of needle penetration depth, and irrigant volume flushed through the canal. The results of this study reiterate the need for more sophisticated methods of irrigation such as ultrasonic irrigation systems.…”

Comparison of efficiency of ethylenediaminetetraacetic acid, citric acid, and etidronate in the removal of calcium hydroxide intracanal medicament using scanning electron microscopic analysis: An in-vitro study

Context:Being integral to root canal therapy, obturation can be performed adequately only after the removal of intracanal medicament. One technique involves the use of chelating agents such as ethylenediaminetetraacetic acid (EDTA) and citric acid. Etidronic acid, a relatively new chelator, has smear layer removal ability and lesser dentinal erosion. It is untested in calcium hydroxide (Ca[OH]2) medicament removal.Aim:The aim of this study was to compare the efficiency of irrigation protocols (EDTA, citric acid, and etidronate) in Ca(OH)2 removal.Materials and Methods:Forty-five single-rooted mandibular premolars were decoronated, instrumented, and filled with Ca(OH)2. After 7 days incubation, Ca(OH)2 was removed by three irrigation protocols (Group-I: 17% EDTA; Group-II: 10% citric acid; and Group-III: 18% etidronate). Roots were split and analyzed (scanning electron microscope, ×1500). Chelator solution pH was tested. Data were analyzed by Kruskal–Wallis ANOVA and Mann–Whitney U-test.Results:Group-III (coronal-third) and Groups-I and II (middle-third) had highest cleanliness scores; Groups-II and III (apical-third) had lowest scores. Comparing the thirds, all groups showed difference in scores. pH of Groups-I, II, and III were 6.8, 1.4, and 0.3, respectively.Conclusion:The solution pH of citric acid and etidronate impacts their Ca(OH)2 removal efficiency in different ways: the highly alkaline pH of Ca(OH)2 increases citric acid pH toward neutrality, where it becomes an inefficient chelator; on the contrary, high acidity of etidronate compensates for its weaker chelation. Etidronate may not require 5 min duration for Ca(OH)2 removal due to the likelihood of dentinal erosion.
