ABSTRACT Aim To gather data from Diplomates of the American Board of Endodontics regarding treatment of dilacerated canals. Materials and methods A questionnaire addressing definition, endodontic treatment procedures and prognosis was constructed and distributed via e-mail to 708 Diplomates of the American Board of Endodontics. Data from 150 respondents, a 21% response rate, were collected by using a Web-based interface. For statistical analysis, Chi-square tests were used. Results More than 25% of respondents believed that a dilacerated root should have a curvature > 40°. One-visit treatment is the best therapeutic approach and transportation is the most likely complication in preparation of these canals. A crown-down technique, watch-winding motion and a master apical file # 25 are the best choices for preparation of these canals. Any warm obturation technique is preferred over lateral compaction by most respondents. Conclusion A crown-down technique for root canal preparation and a thermoplastic obturation technique are recommended for canals whose curvature is more than 40°. The prognosis of the treatment of these canals is judged not lower than normal canals. Clinical significance Crown-down technique and thermoplastic obturation are recommended for dilacerated canals.

The aim of this study was to evaluate the quality of root canal filling performed by undergraduate students at the Federal University of Espirito Santo (UFES). A total of 368 periapical radiographs of endodontic treatment performed by undergraduate students between 2012 and 2014 was assessment. The quality of root canal filling was based on two criteria: length of root canal filling and adequate density of the obturation. Root canal fillings were considered adequate if had no voids and were located at 0-2 mm below the radiographic apex. Statistical analysis was conducted using chi-square tests, with a 5% significance level. In 93.8% of the cases the root canal filling was considered adequate. The density of the obturation was considered inadequate in 3% of the cases. When the length of root canal filling was observed, 1.2% of cases were considered as over-filled and 2.2% were considered under-filled. Non-significant differences were observed among the tooth type (incisive, canines and pre-molars) and the quality of root canal filling. Most of root canal filling performed by undergraduate students at the UFES were considered adequate, regardless of tooth type.

Objective: The aim of this study was evaluate radiographically prevalence of apical periodontitis (AP) in endodontically treated teeth (ETT) and relate with demographic factors, quality of endodontic treatment and coronal restoration. Material and methods: Data were collected from dental records wich contained full-mouth radiographic series. In ETT, arch, dental group and presence of AP were evaluated. Quality of root canal filling, presence and quality of coronal restoration and type of restorative material were also collected. Data were evaluated using descriptive statistics and Chi-square Test. Results: Of 70 patients included in the final sample, the majority were female (54.3%) and age ranged from 13 to 77 years (47.14 ± 13.18). Of 1,333 teeth evaluated, 73 (5.4%) had endodontic treatment, being the majority maxillary (74%) and anterior teeth (52.1%). Of teeth without endodontic treatment, 320 (25.4%) had AP. Failure rate was high (52.8%) and quality of root canal filling and coronal restoration were considered inadequate in majority cases (58.3% and 47.7%, respectively). Dental group had a statistically significant relationship with presence of AP in ETT, being more frequent in anterior teeth (p = 0.019). Conclusion: It was concluded that prevalence of AP in ETT was high and dental group was the factor that most influenced prevalence of AP in ETT.KeywordsApical periodontitis; Radiography; Root canal filling.

The Federal Employee Viewpoint Survey is an annual survey of over 800,000 permanently employed civilian personnel from 87 agencies. First administered in 2002, the web-based survey measures a broad range of employee perceptions, attitudes, and behaviors, serving as a valuable tool for human resources managers to determine which aspects of an organization are working well and which may require intervention. The data collection protocol begins by sending all sampled individuals an initial invitation to participate. Thereafter, nonrespondents are sent weekly reminder e-mails. These notifications are typically sent on Tuesday mornings. In this article, we present results from an experiment investigating two alternative protocols varying when survey notification and reminder e-mails are sent. Interestingly, the stable Tuesday morning strategy produced a significantly higher response rate than the two alternatives, and we analyze timestamp information from one of the alternatives to help provide insight as to why.

Introduction: The present study sought to assess the effect of apical foramen cleaning in the repair of periapical lesions detected by radiography. Methods: The sample comprised 980 teeth collected from 25 February 1997 to 15 March 2005 which had been subjected to endodontic treatment and exhibited radiographically visible periapical lesions. The sample was then divided into two groups: Group I, 402 root canal treatments in which cleaning of the apical foramen had not been performed, and Group II, composed of the remaining 578 root canal treatments where the procedure had been performed. After one year, the teeth were clinically and radiographically evaluated. Results: In Group I, 360 canals (89.55%) had no evidence of periapical lesions, versus 521 (90.13%) in Group II. Partial presence of these lesions was observed in 23 canals (5.72%) in Group I versus 27 (4.67%) in Group II. No changes in images were observed in 19 (4.72%) canals in Group I and 30 in Group II. Pearson’s chi-square test showed no statistically significant difference between the Groups I and II (p = 0.732). Conclusions: These findings suggest that foramen cleaning is not a determinant of periapical lesion repair.

<p><strong>Objective:</strong> To evaluate the effect of glide path creation on transportation promoted by NiTi and M-Wire instruments. <strong>Material and Methods: </strong>Sixty polyester resin blocks containing a simulated root canal were distributed into four groups (n=15), according to the protocols/systems used for root canal preparation: GPR group - glide path + Revo-S system; R group - no glide path + Revo-S system; GPPN group - glide path + ProTaper Next system and PN group - no glide path + ProTaper Next system. Root canals were photographed before and after preparation, and the images were superimposed to evaluate the transportation at the apical, middle and coronal thirds. The time spent to perform preparation was also measured (seconds). Data were submitted to the non-parametric Kruskal-Wallis test (p&lt;0.05) for statistical analysis. <strong>Results:</strong> In the apical third, there was no significant difference among groups (p&gt;0.05). GPR and R groups were similar in the middle third (p&gt;0.05). However, the transportation value in GPR group was statistically higher in comparison with GPPN and PN groups (p&lt;0.05). In the coronal third, GPR and R groups were similar (p&gt;0.05). Only R group presented significant difference in comparison with GPPN and PN groups (p&lt;0.05). There was no difference among groups about time spent to perform preparation (p&gt;0.05). <strong>Conclusion:</strong> None of the systems were capable of maintaining the original trajectory of the simulated root canal, and the glide path had no effect on the transportation promoted by instruments.</p><p><strong>Keywords</strong></p><p>Dental instruments; Endodontics; Root canal preparation.</p>

The aim of this paper was to, on the basis of everyday clinical practice analize the effect of a homeopathic remedy, as a complementary remedy in endodontic therapy of endoperiodontal lesions and chronic apical periodontitis and to radiologically check its effect on the flow and speed of reparation of damaged periodontal tissues. Endodontic therapy was done according to the usual protocol for the therapy of infectious canals with root canal preparation, medication with calcium hydroxide points and hermetic obturation with AH-26 paste. During endodontic treatment patients were taking homeophatic remedy Hepar sulfuris per os three times daily. The remedy stimulates the natural defences mechanism of the organism. Radiological follow up after three months period showed obvious reductiont of radiologic radiolucency in periapical region.

Abstract Objectives The purpose of the current study was to collect information about some techniques and armamentarium currently used by the Saudi Board of Endodontics residents in relation to the technical steps of root canal therapy. Materials and Methods A web-based survey was sent to the Saudi Board of Endodontics residents, based in the western area of Saudi Arabia. The survey assessed controversial concepts, and collected information regarding new instruments and materials, used in the technical steps of nonsurgical root canal treatment. A one-sample chi-square test, with a 95% level of significance, was applied to determine whether there were significant differences between respondents’ answers. Results A total of 45 out of 50 residents (90%) responded to the questionnaire. The majority of Saudi Board residents of Endodontics, who participated in this survey, used the mean of working length (ML) measured by periapical X-Ray and apex locator in the presence of a radiographic lesion (63.3%), and maintained apical patency in all cases (80.0%). ProTaper Universal (40%) and ProTaper Next (41.2%) were the most common NiTi rotary systems used for root canal instrumentation. Thirty percent of respondents used adjunct device with irrigation, and 80% advocated smear layer removal. Zinc oxide–eugenol-based sealers were the most common used sealers (70%), and most residents (86.6%) did not advocate sealer extrusion. Conclusions This study revealed that residents of the Saudi Board of Endodontics program adopt new endodontic technologies. There is, however, a need for more investigations regarding this objective, including responses from all residents in Saudi Arabia.

Objective. To analyze the need for referral to a specialist and to identify the reasons of referrals among Lithuanian general dental practitioners. Material and methods. Questionnaires were sent to all 2879 Lithuanian dental practitioners registered on the Lithuanian Dental Chamber license registry. The questionnaire was made with multiple-choice answers. Respondents were asked to choose only one category of answer that best fitted their clinical attitude. Questions included in the questionnaire concerned general and specific information regarding the need and main reasons for endodontic referral. Results. Of the 2879 questionnaires mailed, 1532 questionnaires containing useful information were returned. The response rate was 53.2%. Of the 1532 respondents, 1431 were general dental practitioners. Majority (72.1%) of the respondents performed complicated root canal treatment by themselves. Almost half (49.6%) of them would like to refer patients to an endodontist. Two of the reasons, which restricted their decision, were the shortage of endodontists and high cost of the procedures in the specialized clinics. Approximately 19% of the respondents referred patients to an endodontist. The main reasons for referral were fractured instruments (86.6%), dental trauma (83.6%), difficulties in diagnostics (79%) followed by persistent symptoms (78.1%). Conclusion. The findings of the present study suggest that the need for referral of patients to an endodontist among Lithuanian dental practitioners exists. The main reasons for referrals were complications of endodontic treatment, traumatic injuries, difficulties in diagnostic procedures, and persistent symptoms.

Periapical Inflammation

ABSTRACT This paper aims at exposing the foundations or reasons why, in cases of external tooth resorption, including those of orthodontic origin, one should not perform a root canal to treat it. That should be done only to teeth with contamination or pulp necrosis, to remove the periapical inflammation induced by microbial products. When facing cases of external tooth resorption, one's conduct must always respect the following sequence of steps: first of all, identifying the cause accurately; then, planning the therapeutic approach and, finally, adopting the conducts in a very well-founded way. The situations in which endodontic treatment is recommended for tooth resorptions are those when there are: a) pulp necrosis with microbial contamination, b) aseptic pulp necrosis, c) developing calcific metamorphosis of the pulp and d) diagnosis of internal resorption. It is not possible, through the pulp, to control the resorption process that is taking place in the external part, after all, the causes are acting in the periodontal ligament. There is no evidence that justifies applying endodontic treatment, by means of root canal, to control external resorption processes, when the pulp shows vitality.
