ABSTRACT Objective To quantify the persistence of residues after endodontic retreatment related to the root canal obturation technique (lateral compaction or single cone) previously performed and the solvent used (xylol or Endosolv-R) in the cervical and root apical segment using digital radiograph. Materials and methods Forty root canals were prepared using the F2 instrument and filled with gutta-percha and AH Plus, 20 canals using #25 point by lateral compaction and the other 20 using F2 point by single cone. The root canals were transversely sectioned, and two segments (cervical and apical) were obtained. Radiographs were taken from the segment in buccolingual and mesiodistal direction, as well as the area that was originally filled with the root canal obturation was measured using ImageJ. After the specimens were set on special devices, the obturations were removed using the rotary system and divided into four groups (n = 10): G1 — lateral compaction and xylol; G2 — lateral compaction and Endosolv-R; G3 — single cone and xylol; and G4 — single cone and Endosolv-R. A new radiograph was taken and the area occupied by residues was measured. The persistence of residues was obtained from the obturation remaining in the root canal in percentage. The data were analyzed using Kruskal—Wallis test (p = 0.05). Results There was no difference among the examined groups, regardless of the radicular segment or the radiograph direction (p > 0.05). Conclusion The endodontic retreatment using xylol or Endosolv-R in the obturations previously performed by lateral compaction or single cone technique presented similar persistence of residues in the root canal, regardless of the radicular segment.

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.

Apex of root is of great interest for endodontists mainly because of different stages involved in its development and the surrounding tissues. Mandibular molars normally consists of 2 roots, one mesial and one distal. About common occurrence, 2 canals are found in mesial root and 1 canal in the distal root. The patient was diagnosed with symptomatic irreversible pulpitis. After cleaning and shaping, the next step is obturation. Lateral canals are complex findings in the apical third of root which is characterized as a lateral canal deviating from the main canal. Normally, this lateral canal is not part of the standard root canal procedure due to the complexities, but sometimes obturation might be possible, which might affect the long-term prognosis of the tooth. Advanced skills are required to attempt and complete obturation of the lateral canal which might be a difficult task for the general practitioners.

The aim of the present study was to assess the quality of canal obturation performed by undergraduate denal students at Saveetha Dental College and Hospitals, Chennai. Records of 200 endodontically treated teeth from patients who were visited by undergraduate students between month of November 2014 to May 2015. Periapical radiographs of all treated teeth were assessed in terms of canal obturation quality (adequate density and length). Forty-five percent of teeth fulfilled the criteria of an acceptable root canal obturation. Adequate length and density of root filling was found in 89% and 34% of teeth, respectively. There was a significant difference between maxillary and mandibular teeth regarding the length of root canal obturation. A significant difference was observed between molars and other tooth types. The frequency of root canals with an acceptable filling was significantly greater in the anterior teeth compared to premolars or molars. The technical quality of root canal treatment performed by undergraduate dental students was found to be less than ideal.

Dental caries is a global concern affecting children and adults. A pulpectomy is considered to be the treatment of choice to preserve the pulpally involved primary teeth. Among the various factors determining the clinical success of pulpectomy, proper obturation of the root canals plays an important role. Different obturation materials are being used for the obturation of the primary teeth root canal, which includes zinc oxide eugenol, calcium hydroxide, calcium hydroxide iodoform paste and combinations. These materials are available in different forms such as powder, powder and liquid, paste forms. Various techniques are available to introduce the obturation materials into the root canal systems. These techniques have been tried to create a three-dimensional fluid-tight seal of the root canals. This review article aims to highlight the different techniques that are being used for the obturation of primary teeth. Each technique has its advantages and disadvantages. Creation of voids within the obturation, underfilling or overfilling are the common problems that can be encountered during root canal obturation. These factors can compromise the clinical and radiographic success of pulpectomy treatment. With the current evidence, no definitive conclusions can be made to decide which is the best obturation technique in terms of clinical and radiographic success. The choice of technique selection depends on the clinician’s preference, cost-effectiveness, time consumption, ease of handling.

An in vitro study was conducted to compare gutta-percha obturation techniques of the developing incisors in dogs. Two perpendicular radiographic views were used for evaluation of apical and overall appearance of root canal obturation. Apical leakage technique was used to evaluate ability of each method to provide adequate apical obturation. The endodontic technique utilizing warm vertical condensation with chemically softened guttapercha in the apical region provided the best radiographic appearance without apical dye leakage. The same vertical obturation technique without the use of chemically softened gutta-percha in the apical region showed 33% dye leakage incidence. Lateral obturation techniques provided the least qualitative radiographic appearance to the endodontic fill and dye leakage incidence. Results of evaluation of quality of apical obturation of root canals based on X-ray examination and apical dye leakage resulted in the following conclusions: lateral obturation techniques used in this study have their limitations resulting from typical root canal anatomy; vertical obturation techniques showed better hermetic apical sealing, mainly in the case of vertical condensation of the chemically softened gutta-percha in the apical part of the root canal.

ABSTRACT Aim To compare the vertical root fracture resistance of endodontically treated teeth obturated using different obturating materials. Materials and methods Decoronated roots of 75 single canal lower second premolar teeth were divided randomly into 5 groups. The first group (Group I) served as a negative control. The remaining four Groups were cleaned and shaped using ProTaper Endodontic rotary files and obturated with guttapercha + TubliSeal EWT sealer (Group II), ThermaFil + AH Plus sealer (Group III), RealSeal + RealSeal sealer (Group IV) and GuttaFlow obturating system (Group V). The roots were then embedded in acrylic resin blocks and subjected to vertical load until fracture with a spreader in a universal testing machine and the forces were recorded. Results Fracture resistance of group I > group IV > group V > group III > group II, which were statistically significant. Conclusion Obturation of roots with resin based obturation material—RealSeal had increased VRF resistance compared to the gutta-percha obturation systems. Clinical significance Obturation of the root canals with resin based obturation system—Resilon reinforces the fracture resistance of endodontically treated teeth and contributes to the overall success of the endodontic treatment.

Hermetical obturation on dentine-cement junction is one of the conditions for success in endodontic treatment. The aim of this paper was to evaluate apical obturation of three different root canal obturation materials. Methods consisted of in vitro semiquantitatively measured penetration of colored solutions. Total number of 55 single-canal teeth was used and obturation test materials were AH-plus, Ketac-Endo and Endomethasone. Linear color penetration was evaluated following illumination of teeth in 2% sol. Metylsalicilate. Results obtained have shown better adhesion between sealer and root canal walls, i.e. better apical obturation when AH-plus (0.25mm) and Ketac-Endo (0.52mm) were used and highest rate of apical leakage when Endomethasone was used (2.35mm). None of the tested obturation materials have sealed apical portion completely.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
O propósito deste estudo in vitro foi avaliar a qualidade de obturações endodônticas em relação ao selamento apical e marginal, comparando duas técnicas de obturação: Condensação Lateral (CL) e Condensação Vertical (CV) da guta-percha aquecida. Foram utilizadas 40 amostras que foram submetidas à penetração passiva de solução de nitrato de prata a 50% e divididas em dois grupos. Para cada grupo de amostras infiltradas foi utilizada uma metodologia diferente. O grupo 1, com cada metade das amostras obturadas com um tipo de técnica de obturação, foi preparado para microscopia Óptica (MO), processamento digital de imagens (PDI) e espectrometria de absorção atômica (EAA). O grupo 2, com metade das amostras obturadas por cada uma das técnicas, foi preparado para microscopia eletrônica de varredura (MEV). Através da MO e PDI, as amostras foram avaliadas quanto à qualidade das obturações, quantificando o percentual de guta-percha e cimento presentes. Através da utilização da EAA, a massa de prata infiltrada na obturação foi quantificada e finalmente, com o uso da MEV, a adaptação marginal dos materiais obturadores às paredes do canal radicular foi avaliada. Nas condições experimentais em que este trabalho foi conduzido e através da análise estatística, concluiu-se que houve diferença estatisticamente significante em relação ao selamento apical produzido pelas duas técnicas de obturação avaliadas e quanto à qualidade de preenchimento das obturações. Nas observações ao MEV, a CV mostrou uma melhor adaptação do material obturador às paredes dentinárias quando comparada com a CL em algumas regiões do canal radicular.
The aim of this in vitro study was to evaluate the quality of endodontics obturations in relation to apical and marginal sealing comparing two obturation techniques: lateral condensation and vertical condensation of warm gutta-percha. Forty samples were used and submitted to passive penetration of a 50% silver nitrate solution. The samples were divided in two equal-sized groups. For each group a different methodology was used. Group 1, with half of the samples obturated by each different technique, was prepared for optical microscopy (OM), digital image processing (DIP) and atomic absorption spectrometry (AAS). Group 2, again with half of the samples obturated by each technique, was prepared for scanning electron microscope (SEM). Using OM and DIP, the quality of the obturation was evaluated and the percent of gutta-percha and sealer present was quantified. Using AAS, the leakage of silver was quantified. Finally, the marginal adaptation of obturation materials in the root canal walls was evaluated with SEM. Statistical analysis showed significant differences in apical sealing produced by the two obturation techniques and in the quality of obturation fillings. In SEM observations, the vertical condensation method showed a better adaptation to the dentin walls when compared with lateral condensation at some regions of the root canal.

O objetivo deste estudo foi avaliar a capacidade de preenchimento de canais laterais simulados pela guta-percha e Resilon, empregando diferentes técnicas termoplastificadoras de obturação: Condensação Vertical Aquecida (CVA), Compactação Termomecânica (CT) e Sistema Obtura II (SO). Foram utilizados 135 dentes humanos unirradiculados extraídos. Após preparo biomecânico, foram confeccionados seis canais laterais simulados em suas raízes, de acordo com a técnica proposta por Venturi et al. (2005). O diâmetro desses canais foi correspondente aos instrumentos # 08 e 10, sendo estabelecidos a 2, 5 e 8 mm do comprimento de trabalho (CT). Os espécimes foram divididos em 9 grupos (n=15), sendo: Grupo I (CVA + guta-percha Dentsply), Grupo II (CVA + Resilon), Grupo III (CVA + guta-percha Odous), Grupo IV (CT + guta-percha Dentsply), Grupo V (CT + Resilon), Grupo VI (CT + guta-percha Odous), Grupo VII (SO + guta-percha Obtura Flow 150), Grupo VIII (SO + Resilon) e Grupo IX (SO + guta-percha Odous Flow). Após a realização das obturações, os espécimes foram analisados pelos métodos radiográfico e diafanização, em função do percentual de preenchimento nos canais laterais, nos três terços. Os resultados foram submetidos ao teste de Kruskal-Wallis, com 5% de nível de significância, de acordo com avaliações específicas intra-grupos: CVA (Grupos I, II e III), CTH (Grupos IV, V e VI), SO (Grupos VII, VIII e IX) e Resilon (Grupos II, V e VIII). As avaliações CVA e CTH mostraram que o Resilon apresentou maior capacidade de preenchimento nas duas análises, em relação aos demais materiais, nos terços apical e médio (p<0,05).

The aim of this study was to evaluate the ability of gutta-percha and Resilon to fill simulated canals using different thermoplastic obturation techniques: Warm Vertical Compaction (CVA), Thermomechanical Compaction (CTE) and Obtura II System (SO). It was used 135 extracted human teeth uniradicular. After biomechanical preparation, six simulated lateral canals were prepared in the roots, according to the technique proposed by Venturi et al. (2005). The diameter of these canals was equivalent to # 08 and 10 instruments and are set at 2, 5 and 8 mm to working length (WL). The specimens were divided into nine groups (n=15), as follow: Group I (CVA + gutta-percha Denstply), Group II (CVA + Resilon), Group III (CVA + gutta-percha Odous), Group IV (CTE + gutta-percha Dentsply), Group V (CTE + Resilon), Group VI (CTE + gutta-percha Odous), Group VII (SO + gutta-percha Obtura Flow 150), Group VIII (SO + Resilon) and Group IX (SO + gutta-percha Odous Flow). After the obturation, the samples were analyzed by radiographic and clearing methods, according to percentage of filling the lateral canals, in the three thirds. The result were submitted to the Kruskal-Wallis test at 5% significance level, according to specific intra-group evaluations: CVA (Groups I, II and III), CTH (Groups IV, V and VI), SO (Groups VII, VIII and IX) and Resilon (Groups II, V and VIII). CVA and CTH assessments showed that the Resilon has great ability to fill lateral canals in the two tests, compared to the other materials, in the apical and middle thirds (p < 0.05). As for SO evaluation, all materials showed good filling capacity of the lateral canals in all thirds, except in the cervical third where Resilon was better by radiographic analysis (extension and area) and in the cervical and middle thirds for clearing analysis (extension)...

The goal of root canal treatment is to eradicate microorganisms in the root canal system of the tooth. However; it has been found that no method of tooth preparation is efficient in eliminating all microorganisms present in root canals. Therefore, obturation materials with anti-microbial properties are advantageous, so that any residual microorganisms in the root system of the tooth can be eliminated. Therefore, the aim of the study was to assess the antimicrobial effect of 3 endodontic sealers: Sealapex™, EndoREZ™ and Guttaflow bioseal™ against Enterococcus faecalis. The Direct Contact test was used to assess the antibacterial effect of the 3 sealers against E. Faecalis. Sample size was n=50 per sealer. The survival of bacteria was assessed by culturing aliquots of 100 μL onto Tryptic Soy Agar plates after 10-fold serial dilutions. After incubation for 24 hours at 37⁰C, colonies on the plates were counted, and the CFU/mL was calculated. The experiments were performed in triplicates. Testing after setting enabled the assessment of the antimicrobial activity of aged sealers after 7 days, 14 days, 21 days and 28 days. All 3 sealers displayed evidence of antibacterial activity against E. Faecalis with various degrees of antibacterial activity at day 0, 7, 14, 21 and 28. Antibacterial activity was displayed by all 3 sealers against E. Faecalis which will have an effect on entombed bacteria.

Resumo:
Total bacterial disinfection and elimination from the human root canal system are crucial in clinical endodontic procedures [Card et al., 2002; Kakoli et al., 2009]. The current approaches relying on mechanical instrumentation and root canal irrigation and medicaments have demonstrated that eradication of bacteria occurs when the bacteria are in direct contact with the medicaments. However, persistent infection following routine treatments has suggested that bacteria may harbor in the root canal anatomical irregularities and/or deep dentinal tubules, therefore, surface irrigation of medicaments may not be able to reach those regions. Heat treatment has been used for obturation of the root canal in endodontic practice. In this study we hypothesize that as an alternative, surface heating using a System B heating catheter through the root canal surface would be effective for bacterial elimination in the deep dentin. The heat-induced cytotoxic response kills bacteria in the root dentin via heat conduction from the thermal energy incident on the root canal wall. In principle, a high power setting and/or a long heating duration can always achieve sufficient temperature elevations in deep dentin. Yet, the detailed temperature distribution inside the dentin and possible thermal damage to the supporting periodontium are unknown. Therefore, it is of clinical importance to perform and investigate temperature elevations in dentin to provide clinicians with an optimized and effective treatment protocol to minimize unnecessary thermal damage to the surrounding structure.
