Objective: The aim of this article is to evaluate the quality of filling in endodontically treated root canals using the lateral condensation technique and modified lateral condensation technique. Materials and Methods: Thirty-two single-rooted teeth were divided into two groups that were assigned by simple randomization according to the filling technique. Once the endodontic treatment was performed, a periapical radiograph was taken to assess the quality according to the radiographic density and tomography was taken to evaluate the quality according to the tomographic volume of spaces, compared with the post-preparation biomechanical tomography. Finally, we performed a statistical analysis (Student’s t-test) to evaluate whether there were differences between the types of filling. Results: Radiographic radiodensity was 182.89 ± 9.81 and 186.72 ± 6.97 HU for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. The void volum...

Background: Sealing the root canal system is an important step in root canal treatment for a successful outcome. Several techniques and materials have been introduced for a three-dimensional obturation with higher density and homogeneity. Void-free filled canals carry a lower risk of apical periodontitis. 2 Guttapercha has long been used as a popular root filling material. Hence; the present study was undertaken for assessing the efficacy Of Two Obturation Techniques Used in Root Canal Treatment of Anterior Teeth. Materials and methods: The present study was conducted in the Department of Conservative dentistry and Endodontics of the Dental institution. For the study, we used 60 extracted permanent maxillary central incisors with single canal and completed apex formation. We excluded teeth with morphological anomalies and multiple root canals to avoid any bias in the results. For the preparation of root canals, access cavity was made and the canal was located using a #8 K-file. Afte...
Modern endodontic principles part 5: obturation
Dental Update, 2016
Once cleaning and shaping is complete the clinician must obturate the canal. There are many different materials and techniques available each with their own discrete advantages and disadvantages. Whichever technique is used, the goal is to seal the entire prepared length of the root canal. This paper describes how best this may be achieved. CPD/Clinical Relevance: It is incumbent on the clinician to ensure that once the canal has been prepared it is sealed from bacterial re-entry.
Quality of obturation achieved by different endodontic obturation systems
2021
Objective: This study was performed to determine in vitro the sealing ability of different endodontic obturation systems and to compare their efficacy. Materials and Methods: In the study were used a total of 36 root canals all of which belong to extracted permanent teeth. Root canals of all samples were prepared with ProTaper Universal rotary files. The teeth were divided into four groups. In each group we had 1 molar with 3 canals, 1 molar with 2 canals, 1 premolar with 1 canal and 3 single-rooted incisors filled by different obturation technique and AH26 sealer. The teeth in the first group were obturated with single-cone technique, in the second group by cold lateral condensation, and the teeth in the third group were obturated with Thermafil. In the fourth group obturation was done with GuttaFlow. After radiography of the root canal fillings, the roots were sectioned horizontally at the level of 2 mm and 4 mm from the apex. The area of gaps and adaptation to canal walls were evaluated using stereomicroscopy and calculated. Results: Evaluation of quality of obturation of root canals based on X-ray examination exhibited compact seal of root canals in all research groups, except with single-cone technique. Evaluation of cross sections revealed that lateral condensation showed the best hermetic sealing and the single-cone technique the worst. GuttaFlow and Thermafil have similar sealing effect. Conclusion: It can be concluded that the density of guttapercha was observed to decrease towards the coronal aspect when the single cone and GuttaFlow were used.

The aim of this study was to determine the percentage of gutta-percha-filled area (PGFA) in the apical third of root canals after filling with either System B or cold lateral lateral condensation techniques. Sixty-six recently extracted human maxillary central incisors were prepared with ProTaper NiTi rotary files and randomly divided into two groups of 33 teeth each. Root canal obturation was carried out as the following: Group 1: Cold lateral condensation technique; Group 2: System B. The teeth were sectioned horizontally at 1, 2, 3, 4 mm from the working length. The total cross-sectional area of each canal was measured and the areas of gutta-percha, sealer and voids were calculated and converted to percentages of total surface area. Data were subjected to the Independent t test. At all levels, System B produced significantly higher gutta-percha filled areas (P < 0.001) and lower sealer and void-filled areas (P < 0.001) than lateral condensation technique. System B exhibited better complete obturation with minimal sealer thickness compared to cold lateral condensation.
Purpose: Post and core requires removal of a portion of the gutta-percha from the root canal space. When guttapercha is removed some factors may have a negative effect on obturating material seal. This study evaluated the microleakage from coronal to apical and from apical to coronal for two different post preparation techniques. Method: Eighty roots were obturated using lateral condensation method with gutta-percha and Gutta- ow sealer and divided into two groups of 40 roots each. Immediate post space preparation was done for one group and delayed preparation was for the other. Two subgroups of 20 roots each were formed to investigate leakage from coronal to apical and from apical to coronal. The extent of leakage was determined using a dye, Indian ink and clearing technique that rendered the teeth transparent. Eight roots were used as positive and negative controls. Dye penetration analysis was carried out using stereomicroscope by a single examiner. Results: The dye in ltration...
Evaluation of Root Canal Obturation: A Three-dimensional In Vitro Study
Journal of Endodontics, 2009
The aim of the study was to measure percentage of volume of voids and gaps in root canals obturated with different obturation materials by using microcomputed tomography (micro-CT). Forty-eight singlerooted teeth were collected and decoronated, and root canals were prepared by using rotary files. The roots were randomly allocated into 4 groups, and each group was obturated by using cold lateral compaction with a different material (gutta-percha and TubliSeal sealer, EndoRez points and EndoRez sealer, RealSeal points and RealSeal sealer, and a gutta-percha point and Gut-taFlow sealer). Roots were scanned with micro-CT, and volume measurements for voids and gaps in the obturated roots were carried out by using specialized CT software. Percentage of gaps and voids was calculated. Statistical analysis showed that gutta-percha exhibited an overall significantly lower percentage (1.02%) of voids and gaps. The present study showed that none of the root canal filled teeth were gap-free. Roots filled with gutta-percha showed less voids and gaps than roots filled with the remaining filling materials.

Comparison of Adaptability of Three Different Root Canal Obturation Materials
World Journal of Dentistry
Objective: The aim was to evaluate and compare the adaptability of the three obturation materials: gutta-percha, GuttaFlow, and Soft-Core to the root canal walls. Materials and methods: Totally 30 mandibular premolar teeth were selected. The teeth were standardized and prepared with ProTaper rotary files. The teeth were randomly and equally divided into three groups-gutta-percha group: obturated with gutta-percha and AH Plus sealer using lateral compaction technique; Soft-Core group: obturated using Soft-Core system; and GuttaFlow: obturated with GuttaFlow. The roots of the teeth were sectioned at three levels (apical, middle, and coronal) and were observed under a stereomicroscope at 40× magnification. Area of voids (AVs), frequency of voids, and location of the voids were analyzed using image analysis software. Results: The lowest mean of AV was obtained by GuttaFlow 1.25% ± 1.93, followed by gutta-percha 1.33% ± 2.16, and Soft-Core 1.74% ± 2.23. Statistical analysis showed no significant difference among the three groups and the levels of the root. The frequency of voids in the coronal and the middle levels was more than the apical for all groups. The highest frequency of voids was detected in Soft-Core, followed by GuttaFlow and gutta-percha respectively. The voids were located in the interphase between sealer and obturation material as well as sealer and root canal walls in the gutta-percha and Soft-Core groups, whereas it was almost confined to the core for GuttaFlow group. Conclusion: GuttaFlow has a better adaptability to the walls compared with Soft-Core system and laterally compacted gutta-percha with AH Plus sealer. Clinical significance: GuttaFlow is an appropriate obturation material to enhance endodontic treatment.

Success of root canal therapy (RCT) is largely dependent upon the quality of biomechanical preparation and obturation of the pulp canal. Improperly cleaned or shaped root canal, regardless of the type of obturation method and obturating material, cannot lead to the success of endodontic therapy. Hence, we conducted a clinical comparative analysis of two obturating techniques. A total of 140 patients receiving RCT at the department of Endodontic were included in the present study. The average follow-up time for the patients was 29 months (18-38 months). Patients were grouped into two depending on the type of obturating technique used. Evaluation of the clinical and radiographic follow-up records of the patients was done and analysis was made. One-way analysis of variance (ANOVA) was used for assessing the level of significance. The average age of the patients undergoing obturation with carrier-based obturation (CO) technique and lateral compaction (LC) technique was 43 and 48 years r...

2018
The aim of this study was to compare the quality of the apical filling in root canals of extracted tooth filled with gutapercha and sealer using different obturation techniques. For this study we selected 200 extracted teeth, devided in 4 study groups, each containing a number of 50 teeth, with fully formed apices and permeable canals. Root canal preparation was performedusing the ProTaper Next System (Dentsply, Ballaigues, Switzerland), in accordance with the manufacturer's instructions. At the end of instrumentation, each root canal was irrigated with 5 ml 17% EDTA (MD Cleanser, META BIOMED) and 5 ml 2% NaOCl (Chloraxid 2% Cerkamed). Root canals of group 1 were filled using cold lateral condensation technique; the group 2 of teeth was filled using warm vertical condensation, continuous wave technique. The third group of teeth was filled using single cone technique. Regarding the fourth group of the teeth we used squirt technique with heated gutta-percha, after application of t...
