AIM: The aim of this study was to evaluate the efficacy of different lengths of time of passive ultrasonic irrigation (PUI) in removing calcium hydroxide (CH) paste from root canal, using scanning electron microscopy and energy dispersive spectrometry (SEM/EDS). MATERIAL AND METHODS: Fifty-four human premolars were used. After coronal access, a size #15 K-file was used to obtain apical patency. Root canal preparation was performed using WaveOne 40.08 instruments. CH paste was placed into the root canal. Specimens were stored in a humid environment, and after seven days, they were divided into five groups (n=12) according to the irrigation protocols: Manual– a size #40 K-file; PUI/1– 1 min; PUI/2– 2 min; PUI/3– 3 min; and Control– without CH paste. An elementary chemical microanalysis (SEM/EDS) was performed to quantify the presence of calcium on the dentinal walls. RESULTS: The percentage of calcium was higher in all experimental groups when compared to the control group (P < 0.05); but no differences among them were found (P > 0.05). CONCLUSION: The amount of calcium hydroxide paste on the dentinal walls was not dependent on length of time of ultrasonic activation. SEM/EDS analysis seems to be a reliable method to assess CH paste removal from the root canals.

Calcium Hydroxide Removal

Aim: To compare the effectiveness of two preparation systems and two irrigation techniques in calcium hydroxide removal from straight root canals. Methodology: Forty-four mandibular premolar teeth were included in this study. The teeth were filled with a calcium hydroxide-based paste and randomly divided into two different preparation groups (Reciproc 50 (R50; VDW, Munich, Germany and ProTaper Universal F5 (PTU; Dentsply Maillefer, Ballaigues, Switzerland). Subsequently, the groups were divided into two subgroups and irrigated using EDDY (VDW, Munich, Germany) and CanalBrush (CB; Roeko, Langenau, Germany) irrigation activation systems. The percentage of calcium hydroxide removed from the canal walls was analyzed using a dental operating microscope (DOM) at 25× magnification. An independent samples t-test, a Mann–Whitney U, Wilcoxon’s tests were used for statistical analysis. Results: There was no significant difference in calcium hydroxide removal throughout the root canal using the R50 and PTU F5 preparation systems (P = 0.847). Both activation systems significantly increased the amount of calcium hydroxide removed from the root canal. Conclusions: EDDY and CB significantly improved calcium hydroxide removal. There was no significant difference between the R50 and PTU F5 systems in calcium hydroxide removal. How to cite this article: Keskin NB, İnce Yusufoğlu S.

Calcium Hydroxide Removal

Because endodontic pathology is caused due to bacterial contamination of the root canal system, endodontic treatment should focus on eliminating microorganisms in root canals. For more than 70 years Calcium Hydroxide has an important role in antimicrobial endodontic therapy. The use of calcium hydroxide is limited by the incomplete removal thereof, a residue covering 20% to 45% of the ductal wall, even after irrigation with NaOCl or EDTA. This study aims to evaluate the removal of calcium hydroxide in root canals using two different techniques.

This study compares conventional endodontic needle irrigation, passive ultrasonic irrigation, apical negative pressure irrigation, and mechanical activation to remove calcium hydroxide from single straight root canals. Eighty-four mandibular premolars were prepared in a crown-down manner up to size #40. Two teeth represented a negative control, and another two served as a positive control. Calcium hydroxide paste was placed inside root canals. The remaining eighty samples were analyzed based on the activation techniques, and the cleanliness of the canals was quantified using Fiji’s software on 500× magnified SEM backscattered electron micrographs. Considering the whole canal, all instruments showed better performance than conventional endodontic needle irrigation in removing calcium hydroxide (p < 0.05). Irrisafe and XP-endo Finisher could remove a significantly higher amount of calcium hydroxide than Endovac (p < 0.05). Irrisafe and XP-endo Finisher have been able to remove more calcium hydroxide than EndoVac.
