Canal filling must be well adapted to the walls of the root canal to prevent bacterial infiltration. Endodontic seals play an essential role in ensuring tightness, without which the canal filling would suffer infiltrations. This study aimed to evaluate the areas occupied by the two components of the canal filling, as well as the sealer/gutta-percha ratio in the root canals of the maxillary central incisors after their filling using the cold lateral condensation technique with gutta-percha. Thirty extracted upper central incisors were rotatably prepared with ProTaper Universal up to F3 and sealed using the cold lateral condensation technique with gutta-percha. After setting the sealer, the roots of the teeth were sectioned perpendicularly to 1 (L1), 3 (L3), 6 (L6), and 8 (L8) mm from the apex. The surface of the sections was analyzed with a Leica EZ4D stereomicroscope and photographed at two magnification orders: 10x and 25x. The areas corresponding to the gutta-percha, sealer, gaps, and root canal were expressed in pixels using the ImageJ software, version 1.50i. The difference in the representation of sealer areas, gutta-percha and voids was statistically significantly different for all four sections analyzed. The best adaptation of the canal obturation was observed in L1 and L3. The gutta-percha area was statistically significantly higher than that of the sealer for the L1, L3, and L6 levels, while the sealer/gutta-percha ratio recorded the lowest value at the L3 level (0, 30) and the highest at its L8 (0.70) level, without registering statistically significant differences regarding the area at the four analyzed levels. The voids were mostly absent or recorded a minimal percentage area (<1%). Cold lateral condensation of gutta-percha has led to a good adaptation of gutta-percha to the root canal wall, with a small amount of sealer, especially to the sections made at 3 mm from the apex. Given the limitations of this study, we noted that the voids were few – observed in the 6 and 8 mm sections – and were negligible in many cases.

Introduction: The aim was to compare root canal wall cleanliness, amounts of apically extruded debris and irrigant during retreatment using the ProTaper Universal Retreatment (PT) system or balanced force technique (BFT). Materials and Methods: Root canals of extracted mandibular premolar teeth (n=44) were endodontically prepared and obturated, then the teeth were divided into two groups: BFT and PT. Apically extruded material was collected into preweighed Eppendorf tubes using the Myers and Montgomery method. The root halves were photographed under a stereomicroscope. Area of the remnant filling material (coronal, middle, apical thirds and total canal surface) was measured by software. Data were analyzed by Mann-Whitney U test. Results: The BFT and PT system provided similar degrees of canal wall cleanliness (p > 0.05) and amounts of extruded irrigant (p>0.05). The PT system caused less debris extrusion (p<0.05). Conclusions: Although the BFT was shown to cause less apical extrusion in primary root canal treatment compared to other manual instrumentation techniques, in the present study, BFT caused more debris extrusion than the PT group.   How to cite this article: Sarıçam E, Altunkaynak B, Kayaoğlu G.

Aim: To evaluate the effect of irrigation techniques, i.e. different types of irrigation needles, on the quality of cleaning of root canal walls using scanning electron microscopy (SEM). Material and Method: The study was conducted on 16 extracted, single-rooted, human teeth. The samples were allocated to two experimental groups depending on the type of the irrigation needle. Conventional needles were used for the irrigation of Group I and laterally perforated ones for Group II. All root canals were instrumented using K files and the Step-back technique. During instrumentation, all samples were irrigated with 2.5 % sodium hypochlorite solution followed by final irrigation with 17 % EDTA for 1 min. After that, all samples were irrigated with 10 ml of distilled water. The roots were, then, sectioned longitudinally and middle one third of each root canal was analyzed using SEM. Quantitative analysis was based on criteria by H?lsmann et al. Results: The obtained results showed that the more efficient removal of debris and the smear layer was accomplished in the group of samples irrigated using laterally perforated needles than conventional needles. The difference between the investigated irrigation techniques were statistically significant (p<0.01). Conclusion: The use of laterally perforated needles for irrigation allows more efficient cleaning of root canal walls, i.e. the removal of debris and the smear layer.

The obturation quality of GuttaFlow Bioseal in curved root canals is not commonly investigated although there has been a current approach toward utilizing this material in extracted molars in recent years. This study assessed the obturated surface area, extrusion of root filling material beyond the apical foramen and duration of obturation procedure in curved root canals using monocone obturation technique. Access cavity was prepared in 20 human mandibular molars. Root canals with curvature of more than 10 as determined according to Schneider’s method were included. Samples were prepared using Hyflex CM rotary files and divided into two groups (n=10): Group 1 [gutta-percha cone and GuttaFlow Bioseal] and Group 2 [gutta-percha cone and RoekoSeal Automix root canal sealer]. The duration of obturation procedure was recorded and obturation radiographs were taken. Samples were bisected and the mesial roots were sectioned horizontally to obtain 3 root segments; apical, middle and coronal. All resected roots were mounted on brass stubs, sputter-coated with thin platinum coating and observed under scanning electron microscope (SEM) at 70x magnification. The SEM images were transferred to the SketchAndCalc Area Calculator software. No statistically significant differences in the obturated surface area and extrusion of root filling material were observed between Group 1 and 2, irrespective of the status of root canal curvature. Duration for obturation in severe root canal curvatures between Group 1 and 2 were statistically significant. Obturated surface area and extrusion of root filling material were not affected by the root canal curvature, however duration for obturation using GuttaFlow Bioseal in severe root canal curvatures was slightly longer.

Endodontic Retreatment

Endodontic retreatment is an attempt to reachieve a healthy periapical after it was previously been carried out an inadequate or reinfected endodontic retreatment that has been filled due to the leakage of apical and coronal. One stage in this retreatment is an uptake of obturasi material using hedstrom file (H-file). The solvent material used in this endodontic retreatment is xylol. Case report. A 22-year-old male patient came to the Clinic of Conservative Dentistry Dental Hospital Prof. Soedomo, Faculty of Dentistry, Gadjah Mada University (UGM) wanted to treat his mandibular second right premolar (45) that has been painful since two months ago. The tooth had root canal treatment one year ago. The pain suddenly appears and disappears as soon as the patient consumes painkillers. Dental preoperative (periapical) radiograph tooth 45 showed a picture of gutta percha root canals and radiolucent images at the tip of the root of the tooth. Diagnosis of tooth 45 is non-vital tooth after root canal treatment accompanied by apical, symptomatic periodontitis. The operator performed a root canal treatment by dismantling the restoration on the occlusal part of tooth 45 and taking gutta percha using a hedstrom file followed by treatment of the root canal, crown lengthening, installation of individual formable fiber post and porcelain fused to metal crown. Conclusion. Retreatment of root canal treatment with non-surgical methods still can be conducted effectively and obtain good results with the final treatment results in smaller lesions in the apical portion of tooth 45.

Root Canal Sealers

The aim of this ex vivo was to investigate if two radiopaque root canal sealers with different formulations would influence the radiographic perception of root canal fillings. The root canals of 48 extracted maxillary canines were prepared and randomly assigned to 3 groups of 16 specimens each. In each group, the root canals were filled by lateral condensation of gutta-percha and one of the tested sealers: Endométhasone, Sealer 26, or a non-radiopaque sealer. A through-and-through void was simulated in half of the specimens from each group (n=8). The buccolingual radiographic images obtained were randomly interpreted for voids existence by a radiologist and an endodontist. The differences in sensitivity and specificity between groups and examiners were compared using, respectively, Fisher's Exact and McNemar tests at 5% significance level. Both radiopaque sealers caused a significant decrease in sensitivity at the coronal part of fillings. The use of Endométhasone increased specificity values for both coronal and apical portions of the root canal fillings. In conclusion, the tested sealers influenced the radiographic perceptions of laterally condensed root canal fillings in a different way.

Abstract Aim The focus of this study was to examine the staining potential of calcium hydroxide (Ca(OH)2) on tooth structure following the removal of AH26 root canal sealer. Methods and Materials Fifty maxillary anterior teeth were prepared and obturated with AH26 and gutta percha. The sealers were then removed 24 hours later and the teeth were randomly divided into two groups. Ca(OH)2 was then placed in the root canals of the first group of teeth as a medicament and camphorated monochlorophenol (CMCP) was placed in the second group of teeth after the filling material was removed. The color of the external tooth surfaces was determined before tooth preparation and two weeks after the placement of the medicaments. The Z test was used for statistical analysis. Results All experimental teeth showed varying degrees of coronal discoloration with the Ca(OH)2 group showing more discoloration than the CMCP group (p<0.05). Conclusion Using Ca(OH)2 as a medicament after removing AH26 caused progressive discoloration of the teeth, whereas using CMCP caused only slight discoloration. Clinical Significance To avoid staining of the treated tooth, AH26 root canal sealer must be completely removed from the dentin walls before using a medicament.

Abstract The aim of this study was to evaluate the integrity of the coronal seal of Temp-Bond and compare it to Cavit and IRM after post space preparation using S. faecalis as a microbial tracer. In addition, the affect of two methods of gutta percha removal on the apical seal of root canal fillings was also evaluated. Forty extracted human single rooted teeth were prepared chemomechanically and obturated with gutta percha and AH26 sealer cement using the lateral cold condensation technique to a standardized working length of 15 mm. About 10 mm of the coronal gutta-percha was removed with either Peeso-reamer or a hot plugger. The roots were divided into three experimental groups of 10 roots and a control group. Each experimental group was subdivided equally into two groups of 15 each according to the method of post space preparation. Cavit, IRM, and Temp-Bond were used to seal the access opening. Each root was fixed in a cuvette containing Tryptic Soya Broth which, covered 2 mm of the root apex. Bacterial suspension was introduced through pipette. Fresh bacterial suspension was added every week, and the system was monitored daily for the growth of microorganisms for a period of one month. The results showed there was no significant difference in terms of coronal leakage between the three coronal materials used (P=0.478), but the methods of gutta-percha removal did have an impact on the apical leakage (P=0.047). The mean value showed the Peeso-reamer provided less leakage compared to using a hot plugger during the 30-day experimental time period. It was concluded the temporary type of coronal seal of endodontically treated teeth will not prevent coronal leakage if left for a long period of time. In addition, permanent cementation of the post with the coronal restoration should be carried out as soon as possible to prevent recontamination of the root canal.

The Difference

Background. Failure of endodontic treatment is commonly caused by the persistent microorganisms remaining in the root canal such as Enterococcus faecalis. Enterococcus faecalis can form a biofilm in tough environmental conditions within the root canals and caused biofilm-mediated infections which needs more complicated treatment due to the increasing of antimicrobial resistance. The biofilm formation initial and most important step is bacteria adherence to the solid surface that is mediated by glucan. NaOCl 2.5% is a commonly used root canal medicaments but can cause injury of periapical tissue. Mangosteen pericarp extract contains flavonoid, tannin, and xanthone have mechanism for inhibiting adherence of bacterial biofilm. Difference of antibacterial activity between NaOCl 2.5% and mangosteen pericarp extract 0.09% can be determined by experimental laboratory to determine the adherence of bacteria in each treatment. Purpose. The aim of this study was to assess the difference of antiglucan activity between NaOCl 2.5% and mangosteen pericarp extract 0.09% on Enterococcus faecalis. Method. This study was designed as an experimental laboratory study with post  test only control group design using Enterococcus faecalis ATCC 29212. Mangosteen pericarp was extracted using maceration method. Adherence analysis was observed after 24 hours by examining the viable cells in suspension. These viable cells are measured by UV-Vis spectrophotometer to compare the suspensions’ turbidity. Using the Independent T-Test, significantly less bacteria were found adhering to the mangosteen pericarp extract. Results. Absorbancy difference level by mangosteen pericarp extract 0.09% is significantly greater than the NaOCl 2.5% (p<0.05). Conclusion. Antiglucan activity that generated by mangosteen pericarp extract 0.09% is greater than NaOCl 2.5%

Background: Root canal irrigation seeks the elimination of bacteria and its products from the root canal. If debris is left in the root canal, it can prohibit adaptation between obturationmaterial and root canal wall. Therefore, it can decrease the sealing ability of obturation material. Purpose: To assess the effectiveness of 2.5% NaOCl and 17% EDTA on the apical sealing ability of resin obturation paste. Method: The roots of 18 human mandibular premolar teeth were selected and the root canal was prepared using a conventional technique. Samples were irrigated with 2.5% NaOCl, and17% EDTA, and sterile aquadest (Aqua Deastilata) as a control group. Samples were filled with gutta-percha and top seal. Samples were soaked in 2% methylene blue for 48 hours to measure the depth of microleakage. Result: The mean apical leakage after irrigation with 2.5% NaOCl; 17% EDTA; and sterile aquadest in the sequence were 0.92 mm; 3.6 mm; and 8.08 mm. Conclusion: 2.5% NaOClhas less depth of microleakage than 17% EDTA. However, the depth of microleakage cannot demonstrate the exact sealing ability of the resin paste due to some factors.

Aim: This study evaluated the effect of a sonic device on the bonding of fiberglass posts cemented with a self-etching adhesive combined with conventional cement or a self-adhesive cement to root dentin. Methods: Forty single-rooted bovine incisors were endodontically prepared using a step-back technique. Gutta-percha and AH Plus sealer were used for root canal filling, combined with a thermoplasticization technique. After 1 week, the post space was prepared and the roots were divided into four groups according to the following factors: adhesive system/resin cement (Ambar/ AllCem Core [FGM] and RelyX U200 [3M]) and application mode (manual or sonic). The posts were cemented and the roots were cut into discs and submitted to push-out bond strength (POBS) test. The failure mode was evaluated using a stereoscope at 25x magnification. The data were analyzed statistically using ANOVA and Tukey’s post-hoc test (α = 0.05). Results: The sonically activated RelyX U200 group was superior to the other groups. RelyX U200 manually applicated showed similar results to those of sonically activated Âmbar/AllCem. These three groups outperformed the Âmbar/AllCem manually applicated group. Adhesive failure between dentin and resin cement was the most predominant pattern. Conclusion: Sonic application of self-etching adhesive and self-adhesive cement improved the POBS of fiber posts to the root canal.
