Aim: To determine the current trends in technological armamentarium and endodontic treatment among Brazilian endodontists. Methods: A total of 279 endodontists answered a web-based survey questionnaire about their region of activity in Brazil and years as a specialist, average number of endodontic cases treated per month, number of visits to complete the treatment, use of rubber dam for isolation, type of irrigant, obturation technique and device used for this purpose, temporary filling materials, and greater difficulty encountered during treatment and technological armamentarium. A descriptive analysis, expressed in terms of frequency and percentage, was performed and the data were correlated using the chi-square test (p0.05). Results: Most of the respondents had up to 10 years as specialists. More than 50% of endodontists preferred to complete the endodontic treatment in a single visit. Ninety-nine percent of endodontists used rubber dam for isolation. NaOCl was the most widely used irrigant. Most of the respondents associated different techniques for root canal filling. Lateral condensation and Continuous wave of condensation were the isolated technique most reported. Filling devices (thermocompactors) were used by 53% of endodontists. Glass ionomer was the preferred temporary filling material. The answers for the use of technological armamentarium revealing that 94% of endodontists used an apex locator; 67.38% utilized magnification (loupe: 23.66%; microscope: 35.48%; microscope and loupe: 8.24%); 58% reported to digital radiography; and 47.31% used computed tomography as a complementary tool. About mechanized instrumentation, 44.44% endodontists employed rotary and reciprocating files. The difficulties encountered during endodontic treatment were classified as preparation > access > obturation > anesthesia > isolation. Conclusions: Most endodontists have implemented new technologies, such as mechanical instrumentation, apex locators, magnification, digital radiography, computed tomography, ultrasound, and obturation tools, in their clinical practice.

Hard Tissues

Internal resorption is a separate category of diseases of hard tissues of teeth, characterized by the loss of dentine as a result of activation and activity of osteoclasts. The article discuss issues concerning etiology, the prevalence of internal resorption, its diagnosis, emphasise the contribution of computed tomography in the diagnosis and prediction of treatment success, clinical decisions and therapeutic treatment of this disease. Describe modern endodontic treatment methods, including the use of magnification, ultrasound in endodontic treatment, the use of certain materials for temporary and permanent root canal filling. Under these conditions, the prognosis of conservative treatment of internal resorption of dental hard tissues is improved, even if there is a perforation of the walls of the tooth cavity.

Lower Incisors

A 52-year-old female patient was diagnosed with chronic periapical periodontitis associated with severely calcified lower central incisors. Radiographic examination revealed no visible root canal in the coronal-third of the root. After choosing the guided endodontic treatment, an intraoral scan (Trios, 3shape, Copenhagen, Denmark), in conjunction with a cone beam computed tomography (CBCT) scan, was taken in order to design and fabricate a printed guide. Virtual implant software was used to visualize the surgical access into the sclerosed root canals. After locating the canals, the guide was removed, and the teeth were treated under a rubber dam. The guided approach allows predictable, efficient endodontic treatment of teeth presenting calcified canals, with minimal removal of sound dentine and less risk of root perforations.

Endodontic Retreatment

The aim of this study is to analyze and compare the efficacy of three non-surgical endodontic retreatment techniques in removing a carrier-based root canal filling material from straight root canal systems. The study was performed on 99 single-rooted extracted teeth using the ProTaper Gold endodontic rotary system up to the F2 file (Dentsply Maillefer, Baillagues, Switzerland), which were sealed with GuttaCore (Dentsply Maillefer, Ballaigues, Switzerland) and AH plus epoxy resin sealer (Dentsply DeTrey, Konstanz, Germany) and randomly assigned to the following non-surgical retreatment techniques: ProTaper Retreatment endodontic rotary instruments (D1–D3 files, Dentsply Maillefer, Ballaigues, Switzerland; n = 33, PTR), Reciproc Blue endodontic reciprocating instrument (R50, VDW, Munich, Germany; n = 33, RCB50), and a combined root canal retreatment technique between Gates-Glidden drills (sizes #3 and #2, Dentsply Maillefer, Ballaigues, Switzerland) and Hedstrom files (file size 35, 30, and 25, Dentsply Maillefer, Ballaigues, Switzerland; n = 33; H-GG). All of the teeth were submitted twice to a micro-computed tomography (micro-CT) scan, before and after non-surgical endodontic retreatment procedures. The volume of root canal filling material (mm3), volume of remaining root canal filling material (mm3), non-surgical endodontic retreatment working time (min), proportion of remaining root canal filling material (%), and efficacy of root canal filling material removal between the non-surgical endodontic retreatment techniques were analyzed using ANOVA one-way statistical analysis. Statistically significant differences were observed between the proportions of remaining root canal filling material of PTR and H-GG (p = 0.018), between the non-surgical endodontic retreatment working times (min; p < 0.001), and between the efficacies of root canal filling material removal by the non-surgical endodontic retreatment techniques (p = 0.009). However, the non-surgical endodontic retreatment systems allow for similar carrier-based root canal filling material removal.

AbstractThis study aimed to compare the efficacy of XP-endo Finisher R and IrriSafe, with a solvent mixture of Methyl ethyl ketone/Tetrachloroethylene (MEK/TCE), in the removal of root filling residues. Twenty-four human mandibular incisors were pair-matched by micro-computed tomography according to volume and aspect ratio. After retreatment, specimens were allocated to two experimental groups (n = 12), according to the supplementary instrument used. The volume of residual filling material after each irrigating step and the time for retreatment was calculated. Statistical analyses were carried out using Mann–Whitney test, with a significance level of 5%. The volume of initial root canal filling material between the groups was similar (p > 0.05). With the final irrigation protocol (NaOCl and EDTA) the volume of the filling remnants decreased significantly (p < 0.05) with no differences between IrriSafe or XP-endo Finisher R (p > 0.05). The additional solvent mixture MEK/TCE increased the efficiency of filling materials reduction, regardless of the agitating instruments employed, IrriSafe or XP-endo Finisher R (p < 0.05). There was no difference between the two groups regarding the time (p = 0.149). Both supplementary instruments were effective in the reduction of filling remnants. The additional step with a solvent mixture of MEK/TCE enabled a total recovery of patency and the achievement of cleaner canals, independently of the agitation instrument.

The biocompatibility of root canal filling material is one of the basic conditions for a successful endodontic treatment and healing of the periodontium. This study was aimed to evaluate the biocompatibility of calcium phosphate cement modified with the styrene-butadiene copolymer-modified calcium phosphate (mCPC) by its implantation in the subcutaneous tissue of rabbit. Fifteen female rabbits of comparable weight were used in this study, each one had received three different tubes; one containing mCPC, the other with mineral trioxide aggregate Fillapex, and an empty control tube on the subcutaneous tissue of thighs. After a definite time (3, 7, and 14 days), the tissues around the tubes were collected, fixed, and processed for histologic evaluation. A histopathological specialist measured the intensity of inflammation. Kruskal–Wallis test was used to analyze the data. The results showed a significant difference with mCPC group in different periods, there was a high intensity of inflammation at the beginning, then it fell, and sustained as mild inflammation. One can conclude that the new formulation of CPC considered biocompatible, which rises the success rate of endodontic treatment.

Objective. To determine peculiarities when using microfocus cone beam computed tomography (micro-CBCT) and cone beam computed tomography (CBCT) to analyze the anatomy of the teeth and the quality of endodontic treatment.Material and methods. Micro-CBCT and CBCT were experimentally used to examine 8 extracted tooth preparations before and after endodontic root canal treatment using different types of filling material.Results. Micro-CBCT showed the high informative value of determining the type, nature, and quality of canal filling and diagnosed many cracks and accessory canals. According to the micro-CBCT findings, the tooth apexes were not filled; the lumen of the canals was unevenly and loosely filled with endodontic material; the passages of guttapercha points were well traced; the nature of the endodontic material was differentiated.Conclusion. Micro-CBCT opens up new opportunities in dentistry with tooth volume visualization, allowing the minor and low-contrast details of the anatomical structure of the teeth to be seen on the X-ray image.
