Area Of Interest

Bacterial persistence has been reported to play critical roles in endodontic treatment failure, which attribute to deficient root canal filling and inadequate chemomechanical preparation. The persistence of bacteria to the different eradication approaches during endodontic treatment has been an area of interest in the field of dentistry due to the different roles by which these bacteria might impact endodontic treatment and can even lead to treatment failure. The present investigation provides evidence regarding the persistence of bacteria and its role in the failure of endodontic treatment. At first, we provided an overview of the potential role that bacterial infections might play in endodontic treatment and how the outcomes can be potentially impacted. Then, we discussed the virulence factors that help the different organisms to persist against the different eradication approaches, which can finally lead to the development of endodontic treatment failure. Our findings show that E. faecalis is the most prevalent bacteria causing endodontic treatment failure. However, many studies have reported that other bacteria and pathogens might also be prevalent and exceed the rate of E. faecalis. This indicates the importance of detecting appropriate biofilms to adequately eradicate the underlying pathogens and enhance the treatment and prognostic outcomes.

The success of endodontic treatment depends on the quality of endodontic treatment and the final restoration. The mean reason for endodontic treatment failure is usually microleakage. That is why it becomes one of the priorities for dental research to prevent microleakage. Infection during the root canal treatment can be prevented. First, by employing strict aseptic clinical techniques follows by cleaning all bacteria and preoperative necrotic pulp-tissue remnants from the root canal. Irrigants are essential in this phase. The shaping of the canal is also an important prerequisite for endodontic success. Removal of the smear layer can enhance seal ability. Second, obturation of the root canal should leave the tooth in the most biological inert condition possible, and it must prevent reinfection as well as the growth of any microorganisms remaining in the canal. The application of an antibacterial dressing between appointments is absolutely necessary or the root canal has to be obturated at the first appointment in order to deprive the microorganisms of nutrients and space to multiply. The temporary filling must be at least 3.5 mm thick. Failure occurs because of missed canals, iatrogenic events and radicular fractures have to be avoided. At the end, clinicians have to confirm that the root canal is cleaned and hermetically obturated because hermetic root canal filling will prevent the leakage of an irritant to the apical area.

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.

Endodontic Retreatment

Endodontic retreatment with direct crown access is the main choice in cases of endodontic treatment failure, even if the practitioner`s effort and duration is significantly greater compared with other procedures. The retreatment with crown access repeats root canal treatment through direct access at the level of tooth crown. The objective is to clean up the canal from irritant agents, such as microorganisms, surviving from the previous therapy or passed through afterwards. Thus, a treatment restart is in accordance with the logics of root canal therapy and is preferred at any time if possible. The aim of this study was to observe, over a 4-year span, the efficiency of endodontic retreatment with direct coronary approach. From 2012 to 2016, 148 patients, with ages ranging from 18 to 65 years, were retreated endodontically. All patients were included in a regular monitoring plan of 3 months and 1-year post treatment. X-rays were performed during these observations, assessed with Orstavik criteria (1991), each radiography having assigned a periapical index (PeriApical Index – PAI). In conclusion, this study confirms that first choice of retreatment in case of endodontic treatment failure is restarting of the retreatment with direct crown access (91% success rate), failure of which leads to a surgical approach using endodontic microsurgery techniques.

Causes Of Failure

ABSTRACTInappropriate mechanical debridement, persistence of bacteria in the canals and apex, poor obturation quality, over and under extension of the root canal filling, and coronal leakage are some of the commonly attributable causes of failure. Despite the high success rate of endodontic treatment, failures do occur in a large number of cases and most of the times can be attributed to the already stated causes. With an ever increasing number of endodontic treatments being done each day, it has become imperative to avoid or minimize the most fundamental of reasons leading to endodontic failure. This paper reviews the most common causes of endodontic failure along with radiographic examples.

This study investigated the effects of endodontic treatment procedures and different post systems rehabilitation steps on the strain and temperature rise on apical and cervical root dentin regions. Twenty-one extracted human canine teeth had two strain gages attached to the distal root surface and two thermocouples attached to the mesial root surface (cervical and apical). The strain and temperature rise were recorded during the following procedures: root canal preparation, final rinse and drying, root canal filling and canal relief. Then the teeth were divided into three groups (n=7), according to the type of post system: CPC, cast post and core; FGP, fiberglass post; and PSP, prefabricated steel post. Data continued to be recorded during the post space preparation, post modeling (only for CPC), post trying and post cementation. Data were subjected to a two-way ANOVA followed by Tukey's test (α=0.05). The post-space preparation caused the highest temperature rise (4.0-14.9 °C) and the highest strain in the apical region during irrespective of post type. The resin cement light-activation resulted in significant temperature increases in the cervical region for all of the groups. The canal relief and the post-space preparation produced highest temperature rises. The CPC post modeling resulted in higher root strain level similarly the level of post preparation. The PSP resulted in highest strain during post trying and post cementation.

Objectives: This study aimed to evaluate the technical quality of root canal treatment performed by fifth-year underperforming students, in the extra sessions of the 2018–2019 academic year. Methods: Periapical radiographs of teeth endodontically treated by underperforming undergraduate students at King Abdulaziz University Faculty of Dentistry, were collected. The quality of obturation was evaluated radiographically in relation to the length of obturation to root apex, homogeneity and density of obturation, root canal tapering, and incidence of mishaps (such as perforation, ledge, missed canal, separated instruments). The data were subjected to descriptive analysis. Results: The periapical radiographs of 70 treated teeth showed acceptable length, filling density and root canal taper in 96 (80%),50 (41.7%) and 66 (55%) root canals, respectively. Only four teeth were subjected to mishaps. Conclusion: Under the circumstances of this study, the quality of endodontic treatment performed by underperforming students at the extra session was low. More studies are needed to address the student underperformance source and hence amend the quality of root canal filling.

This study aims to report the clinical case of a 16 years-old male patient, who attended a private office reporting that at an accident suffered at the age of 10 years-old, which caused extrusive dislocation in both teeth 11 and 21. At that time, the teeth were repositioned, without an adequate follow-up. Upon physical and radiographic examination, the following features were observed: presence of recurrent sinus tract on the vestibular surface, area of ​​external cervical resorption, and a periapical lesion on tooth 21. Endodontic treatments (necropulpectomy) were performed on teeth 11 and 21, with the placement of a root canal dressing of calcium hydroxide and subsequent root canal filling. In addition, soft tissue flap folding was performed to treat the resorption area and to seal it with glass ionomer cement. A 7 months follow-up radiograph shows stabilization in the process of the tooth resorption and remission of the periapical lesion. In conclusion, the endodontic treatment with intracanal medication, and the sealing of the resorption area were successful to preserve the traumatized tooth. In addition, it is noteworthy that following up with the patient after the trauma episode is essential to monitor the pulp vitality of the tooth involved.

Introduction. The main goal of obturation is prevention of reinfection of the root canal system and consequently appearance of periapical lesion. Epidemiological studies have confirmed high prevalence of periapical lesions in endodontically treated teeth with inadequate root canal fillings. The aim of this study was to assess the quality of root canal fillings in teeth treated at students? practical sessions. Iatrogenic errors during endodontic interventions were also assessed. Methods. Two hundred dental records of the patients treated by students in the study program Dentistry at the School of Medicine in Foca during the academic year 2010/2011 were randomly chosen. The length and homogeneity of the fillings or the presence of iatrogenic errors were recorded. A root canal filling was considered adequate if it had correct length and homogeneity in the absence of iatrogenic errors. Two students? curricula V1 and V2 were evaluated for the treatment outcome. Results. Out of 128 endodontically treated teeth, adequate length of the canal filling to the physiological apex was observed in 57% of teeth, homogeneity in 78.9%, while both of these criteria were satisfied in 66 teeth (51.6%). Better quality of root canal fillings was achieved by students of the study curricula V2 and the difference between these two programs was significant (p<0.05). Better quality of root canal fillings in both study programs was recorded for incisors and canines as compared to premolars. Conclusion. The quality of endodontic treatment performed by students was considered adequate in 51.6% of cases. The type of curriculum for endodontic course had a significant impact on the quality of endodontic treatment performed by students.
