The main criterion for successful endodontic treatment is thorough cleaning of the root canal from microorganisms. Modern technologies are being developed to decontaminate the root canal system due to local temperature increase. High-frequency monopolar diathermocoagulation refers to one of these technologies. Aim. To determine the optimal parameters of monopolar high-frequency diathermocoagulation providing a distinct antibacterial effect and which are safe for the surrounding tissues in endodontic dental treatment. Materials and methods. Root canals of single-root removed teeth from the group of upper and lower jaw incisors (12 samples). The DC-35 MS device (2640 kHz, 1. 5 kOhm) was used to study various modes of high-frequency monopolar diathermocoagulation. 6 exposure modes were studied. To determine the heating degree of the tooth root surface, thermometry using a compact infrared radiation converter of the Seek Thermal imager was used, and a remote infrared thermometer Testo 830-T1 was used for temperature monitoring. After determining of the diathermocoagulation modes that are not able to cause significant heating of the surrounding tooth tissues, the antibacterial effect of diathermocoagulation in these modes was studied. To do this, we used clinical strains of optionally anaerobic bacteria obtained from the teeth root canals in pulpitis: Streptococcus sanguis, Streptococcus mutans, Enterococcus faecalis, Escherichia coli and yeast-like fungi Candida albicans. Results. When performing diathermocoagulation of the root canal contents, the third, fourth and sixth modes of the device settings with the power given to the tissue within three seconds of energy in the range of 3.06 W to 5.4 W are safe for the tissues surrounding the tooth root. When treating root canals in the third and sixth modes, the power of diathermocoagulation is 5.4 W and 4.1 W. A multiple, significant decrease in microbial contamination of root canals by all kinds of pathogenic optional anaerobic microflora obtained from the teeth root canals in pulpitis was found.

ABSTRACT Introduction The study aimed to compare the shaping and preservation of the original curvature of simulated curved root canals using the following instruments: Reciproc (Rcp), WaveOne (Wo), and the ProTaper Next system (Ptn). Materials and methods A total of 45 resin blocks with simulated curved root canals were divided into three groups (n = 15), prepared using the Rcp (R25), Wo (25/0.8), and Ptn (X2) instruments. Standardized photographs were taken before and after canal instrumentation. After the superimposition of the images, the amount of resin removed from the curvature's inner and outer walls was measured at six apical levels, at intervals of 1 mm. The canals’ angles of curvature before and after instrumentation were subtracted. Results There were no significant differences between the instruments in terms of the total amount of resin removed of the inner or outer walls of the apical curvature (p > 0.05). The Rcp instruments provided the best resin removed ratios between the walls. The means of the change in angle were as follows: Wo = 2.15°, Ptn = 0.92°, and Rcp = 0.21°. WaveOne caused significantly higher deviations than Rcp. Conclusion All of the instruments demonstrated a tendency to straighten the simulated root canal. Instruments that use rotary movement achieved an effect similar to that of the reciprocating instruments in relation to change in angle. Clinical significance Deviations from the original shape of the root canal could have a negative impact on the quality of a filling and consequently on the success of the endodontic treatment.

Abstract The aim of this study was to evaluate the in vivo efficiency of endodontic treatment with calcium hydroxide in chronic apical periodontitis by determining the microbial load from the endodontic space in different stages of treatment. The microbiological determinations that have been made have led to the conclusion that calcium hydroxide possesses a redoubltable antimicrobial activity, but only with the condition of long-lasting contact with the root canals. Another important result is the essential role of the rigorous biomechanical treatment of the root canals, intracanal medication with calcium hydroxide is addresses mostly to microorganisms located in root canal ramifications.

The objective of this study was to evaluate, in vivo, coronal bacterial infiltration after endodontic treatment with different obturation technique. Forty-five dogs’ root canals, originated from incisors and premolars, were used. The animals were intubated after general anesthesia. After local antisepsis and placement of rubber dam isolation, teeth were opened and instrumented up to a Kerr handfile #40, followed by three obturation protocols with Endofill®: Lateral condensation, Lateral condensation with a coronal plug of set Endofill® and Tagger hybrid technique. Access openings were not sealed and root fillings remained exposed to oral environment for 90 days. After this period, animals were euthanized and specimens were histologically processed and stained with Brown and Brenn. Dentinal tubules were evaluated with presence or absence of bacteria descriptive analysis. Bacterial infiltration was identified on root canal walls in six out of 14 root canals filled with the lateral condensation technique (42,8%), two out of 15 canals filled with Lateral condensation with a plug of set Endofill® (13,3%) and in two out 13 root canals filled with the Tagger hybrid technique (15,3%). Although the use of a coronal plug or a thermomechanical compaction technique showed less bacterial infiltration than conventional lateral condensation, none of the obturation techniques prevented bacterial infiltration to periapical area, evidencing the importance of a proper coronal seal or final restoration.

Radiographic Interpretation

INTRODUCTION Taurodontism is a morphoanatomical change in the shape of a tooth. An enlarged body of a tooth with smaller than usual roots is a characteristic feature. Internal tooth anatomy correlates with this appearance, which means that a taurodontal tooth has a large pulp chamber and apically positioned furcations. This dental anomaly may be associated with different syndromes and congenital discoders. CASE OUTLINE The case report presents the patient of a rare case of taurodontism in the mandibular second premolar with chronic periodontitis. Endodontic treatment was performed after dental history and clinical examination. Special care is required in all segments of endodontic treatment of a taurodontal tooth from the identification orifice, canal exploration, determining working length, cleaning and shaping and obturation of the root canal. Precurved K-file was used for canal exploration and location of the furcation. One mesial and one distal canal with the buccal position were identified in the apical third of the root canal. The working lengths of two canals were determined by radiographic interpretation with two K-files in each canal and verified with the apex locator. During canal instrumentation, the third canal was located in the disto-lingual position. The working length of the third canal was established using the apex locator. CONCLUSION Thorough knowledge of tooth anatomy and its variations can lead to lower percentage of endodontic failure. Each clinical case involving these teeth should be investigated carefully, clinically and radiographically to detect additional root canals. High quality radiographs from different angles and proper instrumentarium improve the quality of endodontic procedure.

Abstract Background: Evaluation of changes in volume after root canal preparation. with single file rotary systems such as Reciproc-Blue, WaveOne-Gold and XP-EndoShaper, with a new in vivo study model using CBCT and 3D reconstructions on patients Methods: Thirty human lower premolars were randomly divided into three groups, in which the root canals were prepared using one of these single-file systems: Reciproc-Blue, WaveOne-Gold and XP-EndoShaper. Root canals were scanned before and after root canal preparation using CBCT, and a 3D reconstruction was performed with RHINOCEROS 5.0 software to assess the increase in canal volume for each group after instrumentation. The Anova test was used to determine statistically significant differences between the groups and Post-hoc Tukey's-test to compare the groups with each other. Results: The proposed 3D-reconstruction model allows to measure the variation of the volume within the root canal of the premolars studied. With this model, Reciproc-Blue showed higher increase in canal volume, followed by WaveOne-Gold and XP-EndoShaper (Anova p = 0.003). XP-EndoShaper did not show a statistically significant increase in canal volume after root canal preparation (Tukey's test for paired data p = 0.06 confirmed the results with each other).Conclusion: it is possible to use CBCT and 3D reconstruction as a model to study the preparation quality of the root canal in vivo. With this model, Reciproc-Blue showed higher increase in root canal volume, followed by WaveOne-Gold, while XP-EndoShaper did not significantly increase root canal volume during preparation.

Background and Objectives: Chitosan, a polysaccharide derived from squid pens – the squid waste, is gaining considerable interests in biomedical engineering due to the biodegradability, biocompatibility, nontoxicity, and antibacterial activity. It is necessary to eradicate the bacteria from root canal in endodontic treatment, including Porphyromonas gingivalis. P. gingiva- lis is one of the most prevalently found bacteria in root canals and its presence can cause endodontic treatment failure. This study was conducted to find the antibacterial effect of chitosan from squid pen against P. gingivalis at a certain concentration. Materials and Methods: Chitosan 1.5% (w/v) was diluted in several tubes. The lowest concentration with no bacterial growth was considered to have antibacterial activity against P. gingivalis. Results: There was no bacterial growth in nutrient agar media at the concentration of 10.75%. Conclusion: Chitosan that was made from squid pens has antibacterial activity against P. gingivalis.

Abstract Background The purpose of this study was to evaluate the changes in canal volume after root canal preparation in vivo with 3 different single-file techniques (Reciproc-Blue®, WaveOne-Gold® and XP-EndoShaper®), with a new method using CBCT and 3D reconstruction. Methods In this prospective study, thirty human lower premolars from healthy patients were used, in which extraction was indicated for orthodontic reasons. All the teeth used were caries- and restoration-free with complete root development, without signs of periodontal disease or traumatic occlusion, and with only one straight canal (up to 25º curvature). Teeth were randomly divided into three different groups: Reciproc-Blue, WaveOne-Gold and XP-EndoShaper. CBCT scans before root canal preparation were used to create a 3D reconstruction with RHINOCEROS 5.0 software to assess the initial canal volume, and then compared with 3D reconstructions after canal preparation to measure the increase in canal volume. Student’s t test for paired data were used to determine statistically significant differences between the before and after canal volumes. Anova test was used to determine statistically significant differences in the percentage of canal volume increase between the groups and Tukey's post-hoc test were used to paired comparison. Results Reciproc-Blue showed the higher increase in canal volume, followed by WaveOne-Gold and XP-EndoShaper (p = 0.003). XP-EndoShaper did not show a statistically significant increase in canal volume after root canal preparation (p = 0.06). Conclusion With this model, Reciproc-Blue showed higher increase in root canal volume, followed by WaveOne-Gold, while XP-EndoShaper did not significantly increase root canal volume during preparation.

Background Reciproc instruments are the only contemporary root canal instruments where glide path preparation is no longer strictly demanded by the manufacturer. As the complete preparation of root canals is associated with success in endodontic treatment we wanted to assess the ability and find predictors for Reciproc instruments to reach full working length (RFWL) in root canals of maxillary molars in primary root canal treatment (1°RCTx) and retreatment (2°RCTx) cases. Methods This retrospective study evaluated 255 endodontic treatment cases of maxillary molars. 180 were 1°RCTx and 75 2°RCTx. All root canals were prepared with Reciproc instruments. The groups were compared and in a binary logistic regression model predictors for RFWL were evaluated. Results A total of 926 root canals were treated with Reciproc without glide path preparation. This was possible in 885 canals (95.6%). In 1°RCTx cases 625 of 649 (96.3%) canals were RFWL and in 2°RCTx cases 260 of 277 (93.9%). In second and third mesiobuccal canals (MB2/3) 90 out of 101 (89.1%) were RFWL with Reciproc in 1°RCTx and in the 2°RCTx treatment group 49 out of 51 cases (96.1%). In mesio-buccal (MB1) canals “2°RCTx” was identified as negative predictor for RFWL (OR 0.24 (CI [0.08–0.77])). In MB2/3 canals full working length was reached less often (OR 0.04 (CI [0.01–0.31])) if the tooth was constricted and more often if MB2/3 and MB1 canals were convergent (OR 4.60 (CI [1.07–19.61])). Discussion Using Reciproc instruments, the vast majority of root canals in primary treatment and retreatment cases can be prepared without glide path preparation.
