Background The aim of this study was to assess the clinical impact of non-surgical root canal treatments (NSRCT) performed with different treatment protocols on the probability of tooth survival without untoward events and to identify predictors influencing the outcome. Methods During the period from July 1999 to October 2016, 5,858 patients were identified in which 9,967 NSRCTs were performed. The treatments were followed up and divided into three groups. In Group 1 root canal treatment was performed with hand instruments, in Group 2 with multiple file rotary instruments and passive ultrasonic irrigation (PUI), and Group 3 was treated with Reciproc instruments and PUI. Untoward events were defined as orthograde retreatment, apicoectomy or extraction of the tooth after initial treatment. Weibull regression was used to analyse the data. Results A total of 9,938 cases could be included into the analyses. The results showed 5-years predicted survival rates without untoward events of 73.9% (95% CI [71.7%–76.1%]), 75.1% (95% CI [71.7%–78.0%]) and 78.4% (95% CI [75.1%–81.4%]) for study group 1 (N = 5,580), 2 (N = 1,700) and 3 (N = 2,658), respectively. The differences between Group 1 and 3 were statistically significant (p < 0.006). Higher age of the patient (per year increase) and number of earlier NSRCTs (per unit increase) reduce the survival without untoward events statistically significant (both p < 0.02), while treatment of premolars had a statistically significant lower hazard ratio [0.89 (95% CI [0.79–0.99]; p = 0.030)] compared to treatment of molars and anterior teeth. A higher number of supportive periodontal treatments (per unit increase) improved tooth survival without untoward events highly significant (p < 0.0001). Discussion More recent endodontic treatment protocols involving reciprocating instruments and PUI appear to be associated with higher tooth survival rates without untoward events compared to hand instruments.

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.

This paper represents a part of research plan of “Advanced Endodontic Technology Development”. In order to aid endodontic treatment a 3-D computer model of root canals has been created which shows the geometrical characteristics. The extent of work needed for root canal treatment is obtained from this 3-D model. The objective of this paper is to convert the geometrical characteristics into automatic treatment procedure planning. This computer-aided process planning for endodontic treatment determines tool selection and process method. It also calculates tool path and optimum tool movement distance. The output of this planning system is a numerical controlled program. Because of paper size limitation, only tool selection and path control during coronal canal treatment preparation for anterior teeth are discussed in the paper. The computer-aided treatment procedure planning system provides transformation from a 3-D canal model to a machine-controlled program that will yield a treated root canal ready for filling. It serves as a bridge between design (3-D canal model) and manufacturing (canal treatment). Unlike conventional methods for root canal treatment, the computer-aided treatment process planning system emphasizes a non-destructive internal tooth geometry examination and less invasive access preparation.

Retrospective Assessment

ABSTRACT Introduction A thorough knowledge of the anatomic morphology of the root canal system is necessary for the long-term success of the root canal therapy. The occurrence of C-shaped root canal configuration is one such variation. Achievement of favorable prognosis after commencing root canal therapy in such teeth is one of the challenges imposed on the endodontist. Hence, we evaluated the healing occurring after endodontic therapy in patients with C-shaped root canals in mandibular molars. Materials and methods The present study was conducted in the Department of Conservative Dentistry of the institution and included assessment of all the patients who underwent root canal treatment of the mandibular first and second molars. Endodontic therapy was performed in all the cases by experienced endodontist. Final postoperative radiographs were taken. Recording of the data of the personal and clinical details of a total of 250 patients was done. All the clinical and radiographic details of the patients, such as tooth location in the jaw, presence or absence of C-shaped canals, status of the pulp tissue, presence or absence of the fractures, and other details of the patients were recorded. Radiographic and clinical examination of the tooth of the patients was done during the baseline visit and further during the follow-up visits. The presence of C-shaped root canals was confirmed using the radiographs. Periapical index (PI) scoring system was used. Categories defined for enlisting the healing after the root canal treatment with the assessment of the PI score. All the results were analyzed by Statistical Package for the Social Sciences software. Results Vital pulp tissue was encountered in majority of the cases. C-shaped root canal configuration was observed in 40% of the cases included in the present study. After completion of the endodontic therapy, complete crown placement was done in only 22% of the cases. In cases of vital teeth with C-shaped root canals configuration, most of the teeth showed complete healing. Significant results were obtained while comparing the complete coverage crown parameter in relation to the healing process in teeth with C-shaped root canals. Conclusion In the present study, no significant effect of the C-shaped root canal configuration was found on the healing rate of the endodontic therapy in mandibular molars. Clinical significance Meticulous endodontic therapy with special techniques should be done while preparing teeth with C-shaped root canals.

Regenerative Endodontic Treatment

Traumatic dental injuries are particularly common in school-age children and often occur in the anterior region. Process management of cases is possible with alternative treatments according to the root development levels. This case series is aimed to present the treatment and 2-year follow-up of permanent anterior teeth with traumatic dental injuries. Case 1: An 8-year-old patient, who had a bicycle accident 20 days earlier, was diagnosed with extrusion of #31. Due to late admission to the clinic, no repositioning procedure was applied to the tooth. Regenerative endodontic treatment was performed. During the radiological follow-up, the apex was closed in the 12th month; however, it was observed that obliteration started in the root canal at the 24th month. The case is still being followed up at regular intervals. Case 2: A 13-year-old patient, who had a traffic accident 3 days prior, was diagnosed with subluxation in #11, and a root fracture was detected in the apical third of #21. In #21, root canal treatment was applied to the coronal part of the fragments. After the diagnosis of pulp necrosis in #11 in the 2nd month of the follow-up period, root canal filling was applied. During the follow-up period, no pathology was detected and no granulation tissue was formed between the fragments in #21. In traumatic dental injuries, long-term follow-up, well-timed endodontic treatments, and material selection play an important role in success. With regenerative endodontic treatment, successful results can be obtained even in treatments applied in late-admitted patients.

Object. Causes of failure of endodontic treatment and causes of tooth extraction with a diagnosis of chronic apical periodontitis. Purpose ― to analyze the causes of failure of endodontic treatment and the causes of tooth extraction with a diagnosis of chronic apical periodontitis to determine ways to improve the effectiveness of conservative treatment. Methodology. A retrospective analysis of 864 medical records of a dental patient and 532 results of x-ray examinations of patients who underwent tooth extraction was carried out. 198 dentists-therapists of the city of Tyumen and the South of the Tyumen region were interviewed to determine the shortcomings of endodontic treatment. During the survey, doctors expressed their subjective opinion about the main reasons for the failure of therapeutic treatment of teeth with apical periodontitis and the reasons for their subsequent tooth extraction. Results. According to the survey, the failure of conservative treatment is most often associated with non-compliance with treatment protocols and the complexity of the anatomical structure of the root canals, as well as the inability to adequately clean the root canal system. A retrospective analysis of the data related to tooth extraction revealed that the main cause of tooth extraction is chronic apical periodontitis, which accounts for 69 %. The main reason for the removal of teeth diagnosed with chronic apical periodontitis was a significant destruction of the crown. Summary. In the course of this work, we justified the need to improve existing methods of conservative treatment of apical periodontitis. Improvement of endodontic treatment should be aimed at the development and implementation of effective methods of root canal cleaning and irrigation solution activation. In order to improve the prognosis of endodontic treatment and reduce the proportion of tooth extractions for periodontitis, it is necessary to improve the quality of the final restoration and to monitor its tightness.

Introduction. Knowledge of root canal morphology is one of the main prerequisites for successful endodontic treatment. We present the case of a patient with multiple canals in lower anterior teeth which were treated endodontically. Case Report. To a 45-year-old patient endodontic treatment was applied on lower left lateral incisor, lower right central and lateral incisor and lower right canine. These teeth were previously prepared for prosthetic crowns. All involved teeth had two canals which were not visible on the primary radiographs. Gracility of remaining tooth structure and canals and the presence of two canals in each tooth required additional radiographs for verification of multiple canals. Careful biomechanical instrumentation and irrigation with use of lubrication due to narrow canals was performed. The canals were obturated with gutta-percha using lateral compaction technique and Acroseal (Septodont) paste. On the control checkup after eight months, the patient was asymptomatic, while clinical finding was normal. Conclusion. Complexity of presented case was even more significant because these teeth were prepared to support prosthetic superstructure and crowns, and every ?forgotten? canal is an iatrogenic error.

Background and Aim: The success of endodontic treatment depends on the complete elimination of pathogenic bacteria inside the root canal. Enterococcus faecalis, a gram-positive, pathogenic, and anaerobic cocci, are the primary etiology of root canal infection in treated and untreated teeth and are highly associated with endodontic treatment failure. This study aimed to compare the antimicrobial activity of Sodium hypochlorite 2.5%, microemulsion of Myrtus 10%, and microemulsion of Thyme 0.6% on the E. faecalis after root canal filling. Methods & Materials: In this experimental study, 25 extracted single canal human anterior teeth were collected, and their crowns were cut. Then after washing and cleaning, and filling, the sterilization was done using an autoclave. Then, except 5 teeth (negative control group), the teeth were smeared with E. faecalis and then divided into 5 groups randomly represented the irrigation by Sodium hypochlorite 2.5%, microemulsion of Myrtus 10%, and microemulsion of Thyme 0.6%, with a positive control group and negative control group. The teeth were filled with gutta-percha and then incubated in an incubator for 90 days at a temperature of 37°C. Finally, the comparison of CFU in the groups due to abnormal data distribution was performed using the Kruskal-Wallis test. Ethical Considerations: The Ethics Committee of Arak University of Medical Sciences approved this study (Code: IR.ARAKMU.REC.1398.297). Results: According to the results of this study, the correlation between the groups of cultured teeth was not significant(P>0.05). The specimens washed with microemulsion of the Thyme 0.6% had the highest positive number of cultures; the specimens washed by Sodium hypochlorite 2.5% had the lowest number of cultures. Conclusion: This study showed that no statistically significant difference exists in their antimicrobial activity after root canal therapy after the use of different wash solutions.

Ultrasonic tips and anatomic finishing files have been used as strategies to improve the cleaning and disinfection of root canals, especially in complex anatomies. These instruments are also subjected to fractures, which can hinder the endodontic treatment and negatively affect the outcome. This article presents two cases of successful management of intracanal-fractured instruments with unfavourable prognosis, emphasizing on treatment protocols and outcomes. Two 14-year-old female patients underwent root canal treatment of teeth 37 (case 1) and 47 (case 2). During the final irrigation protocols, case 1 presented a fractured XP-Clean file within the mesiobuccal canal and within the distal canal in case 2, which also showed fractured E1-Irrisonic tips within the mesiobuccal and distal canals. Non-surgical management and bypassing retained instrument fragments were successful in both cases and they may be considered adequate approaches.

Objective: To assess the post-operative pain by using calcium hydroxide Ca(OH)2 based root canal sealer, a clinical study at tertiary care Hospital Materials and Methods: This cross-sectional study was performed at operative dentistry department of Liaquat University of Medical and health Sciences Jamshoro Pakistan. Study duration was 6 months from March 2020 August 2020. Total 60 patients, those having permanent anterior teeth with irreversible pulpitis, teeth restoration after root canal treatment and either of gender were included. Multiple visits of endodontic treatment were performed by obturating the canals using calcium hydroxide Ca(OH)2 (sealapex, Sybron endo). Patients were recalled next day, after 3rd day and after one week of obturation to assess the severity of post-operative pain (POP) via visual analogue scale (VAS). All the information was recorded via study proforma. Data analysis was done by using SPSS version 20. Results: Mean age of the study participants was 26.77+8.72 years. males were in majority 36(60.0%). On the next day as per severity of pain, mostly patients were presented with severe pain as mean visual analogue scale was 8.7+0.3. On third day pain was markedly decrease among almost all of the cases as average of visual analogue scale was found 2.6+0.2. However after one all the patients were seen without pain as average of visual analogue scale was 0.65+0.7. Pain was statistically insignificant according to gender. Conclusion: Calcium hydroxide based root canal sealer found to be feasible and effective for endodontic treatment in terms of lower postoperative pain.

ABSTRACTObjectives: To assess the incidence of postoperative pain after single- and multi-visit endodontic treatment of teeth with vital and non-vital pulp.Methods: In total, 306 patients with teeth requiring endodontic treatment were identified and were included in this study. Two experienced clinicians treated the patients, who were randomly assigned to two groups. While the teeth of patients in group 1 were obturated, group 2 were temporarily sealed and obturated after one week. Three days after the root canal instrumentation of each tooth, the patients were asked whether they experienced any postoperative pain and to rate the level of discomfort as no, mild, moderate, or severe pain. Data were analyzed statistically using the chisquare test.Results: No significant difference in postoperative pain was found between vital and non-vital teeth (P>.01). Mild, moderate, and severe pain occurred in 31.4, 13.7, and 4.6% of vital teeth, respectively. Postoperative pain occurred in 107 (69.9%) and 106 (69.3%) teeth in the single- and multi-visit treatment groups, respectively. There was no significant difference in postoperative pain between the two groups (P>.01).Conclusions: The prevalence of postoperative pain did not differ between vital and non-vital teeth. The majority of patients in either groups reported no or only mild pain. (Eur J Dent 2009;3:273-279)
