The endodontic retreatment is a feasible solution when post-operative apical periodontitis persists or develops. The complete removal of the filling materials is important in order to ensure the unobstructed contact of the intracanal disinfectants with the microbes. As a new generation of bioceramic endodontic sealers has emerged, their removal efficacy from the root canal system during retreatment is a matter of concern among clinicians. The aim of this article is to provide a comprehensive review of the current literature on the retreatability of these novel obturating materials. A significant amount of bioceramic sealer remnants in the root canal walls was observed in all studies.  Even though canal cleanliness could not be obtained at an ideal level, the re-establishment of the working length and patency can be considered manageable and comparable to other endodontic sealers.

ABSTRACT Microorganisms invading the root canal system of a tooth may interact with the host tissue and cause pulpo-periapical pathosis. The goals of root canal treatment are to disinfect the root canal system and to prevent subsequent reinfection. The disinfection is attempted with endodontic instruments, irrigants, and medications. Due to the complex canal anatomy, microorganisms can persist even after thorough disinfection regimens are used. After disinfection, the canal is sealed with a root filling material along with sealers. To curtail residual microorganisms, root-filling materials should ideally be bactericidal, as well as biocompatible. In addition, the root filling materials are expected to act as a physical barrier to prevent the leakage of substrate to any residual microorganisms and the ingress of additional microorganisms. The aim of the present study was to assess the antimicrobial activity of various Endodontic sealers on the Enterococcus faecalis. Enterococcus faecalis is a microorganism commonly detected in asymptomatic, persistent endodontic infections. In the changing face of dental care, continued research on E. faecalis and its elimination from the dental apparatus may well define the future of the endodontic specialty.

Endodontic Retreatment

It is a well-recognised fact that incomplete cleaning, shaping and obturation of root canals will lead to endodontic failure. Mandibular second premolars usually have a single root and a single root canal. The presence of four separate roots and four root canals is quite rare. Hence, a comprehensive knowledge about the normal canal configuration along with its variations becomes an indispensable pre-requisite to achieve the success of endodontic treatment. Authors hereby present a case of a 26-year-old male patient and describe its succesful treatment of the mandibular second premolar with four roots and four root canals. The clinical implications of this paper aim at establishing an accurate diagnosis of the root canal system using diagnostic aids such as angulated radiographs and making use of advanced endodontic instruments for successful retreatment of endodontic therapy (C+ files and NiTi rotary endodontic instruments).

Abstract Aim The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy. Background The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal treatment. Dens invaginatus is a rare dental anomaly that can give rise to many complex anatomical forms. The complete removal of the diseased pulp tissue can be a challenge for clinicians due to the complexity of internal canal anatomy and may require either non-surgical endodontic therapy alone or that therapy may have to be combined with surgical endodontics to achieve an adequate sealing of the root canal system. Case Report A 22-year-old male presented for evaluation of a recurrent painless sinus tract in the attached gingiva adjacent to the maxillary right lateral incisor. The tooth responded negatively to vitality tests while the right central incisor responded normally. Clinically an anatomical malformation in the crown was detected in the form of an abnormal bulbous contour of the tooth in the palatal region above the cingulum. Radiograph evaluation confirmed the presence of dens invaginatus and a periapical radiolucent lesion. The patient received combined nonsurgical and surgical endodontic therapy to achieve a favorable outcome. Summary Complications presented by Type III dens invaginatus and acute periapical abscess necessitated the use of combined non-surgical and surgical endodontic therapy to attain a favorable seal of the root canal. The prognosis at a six-month post-treatment evaluation appeared to be good. Clinical Significance Dens invaginatus requires an early diagnosis and treatment. It may result in radicular and periapical pathosis requiring a combined non-surgical and surgical endodontic approach to treatment. Citation Hegde MN, Shetty A, Sagar R.

AbstractIn case of failed root canal treatment endodontic retreatment of the root canal system is necessary. The aim of the present study was to compare the gutta-percha removal with Protaper retreatment files (Dentsply Maillefer, Ballaigues, Switzerland), K3 (SybronEndo) and Hero Shapers (MicroMega, Besancon, France). Method: Thirty freshly extracted human single rooted teeth were prepared with ProTaper rotary instruments up to file F3 andfilled with 30 # GP cones and AH plus sealer. The teeth were then stored for 1 week. The teeth were divide into 3 retreatment groups (n=10). The gutta-percha was removed using Protaper retreatment files, K3 and Hero Shapers. Teeth were then evaluated using radiographs. Results: Comparing the ratio between clean canals Protaper and K3 showed better debris removal as compared to Hero shaper. But no significance difference was found.

Introduction: The present study compared the ability of the endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal system in association with gutta-percha. Methods: Ninety mandibular premolars were accessed, prepared and divided into three groups of 30 teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal Sealer and EndoREZ. All the teeth were filled using the continuous wave of condensation technique. The specimens were then decalcified, dehydrated, rendered transparent, and analyzed by three independent evaluators with 8x magnification. Chi-squared test (χ2, p < 0.05) was used to compare the groups in relation to the totally filled, the partially filled and the non filled ramifications. The same test was used to compare the directions of filled ramifications and the number of ramifications among the three thirds of the roots. Results: EndoREZ filled a significantly higher number of ramifications than AH Plus and Pulp Canal Sealer (χ2, p < 0.05). All the groups showed higher number of totally filled ramifications than partially filled and unfilled ramifications. The ramifications were more frequently detected in the apical third, followed by medium and coronal thirds, respectively (χ2, p < 0.05). The ramifications were more frequently detected towards lingual direction (χ2, p < 0.05). Conclusion: EndoREZ presented higher ability to fill the root canal system in association with gutta-percha when compared to AH Plus and Pulp Canal Sealer. The ramifications were more frequently detected in the apical third, running in a lingual direction.

ABSTRACT Objective The aim of this study was to compare the cleaning of main and lateral canals using the irrigation methods: negative pressure irrigation (EndoVac system), passive ultrasonic irrigation (PUI) and manual irrigation (MI). Materials and methods Resin teeth were used. After root canal preparation, four lateral canals were made at 2 and 7 mm from the apex. Root canals were filled with contrast solution and radiographed pre- and post-irrigation using digital radiographic system [radiovisiography (RVG)]. The irrigation protocols were: MI1—manual irrigation [22 G needle at 5 mm short of working length-WL]; MI2—manual irrigation (30G needle at 2 mm short of WL); PUI; EV1—EndoVac (microcannula at 1 mm short of WL); EV2—Endovac (microcannula at 3 mm short of WL). The obtained images, initial (filled with contrast solution) and final (after irrigation) were analyzed by using image tool 3.0 software. Statistical analysis was performed by analysis of variance (ANOVA) and Tukey tests (5% significance level). Results EV1 and EV2, followed by PUI showed better cleaning capacity than manual irrigation (MI1 and MI2) (p < 0.05). Conclusion Negative pressure irrigation and PUI promoted better cleaning of main and simulated lateral canals. Clinical significance Conventional manual irrigation technique may promote less root canal cleaning in the apical third. For this reason, the search for other irrigation protocols is important, and EndoVac and PUI are alternatives to contribute to irrigation effectiveness.

Objective: This systematic review aimed to discuss a possible effect of sodium hypochlorite (NaOCl) over the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the new generation of corona virus, which was reported firstly in December 2019 in Wuhan, China. Methods: Electronic search was performed for studies up to March 31, 2021 in the following databases: PubMed, LILACS, BBO, Scopus, web of science and Cochrane considering clinical trials and laboratory studies that evaluated the action of NaOCl over SARS-CoV-2. Results: Numerous founded studies reported effectivity of NaOCl in different concentrations and exposure times over corona viruses including the SARS-CoV-2. However, none of the studies evaluated this action in the root canal system. No metanalysis was conducted due to variability of methods or lack of information of included articles. Conclusion: NaOCl has a possible effectivity over SARS-CoV-2 as it dissolves the organic material of virus membrane, but this should be evaluated in the root canal systems.

Root Canal System

Introduction: The purpose of endodontic treatment is to eliminate the bacterial infection in the root canal system and allow healing of apical periodontitis. Sometimes the anatomical complexity of the root canal system makes complete removal of bacteria almost impossible even if the conventional methods of chemo-mechanical debridement are performed strictly according to the protocol. So additional methods of root canal disinfection can be applied such as photoactivated disinfection (PAD). Purpose: The aim of our study was to compare the antibacterial activity of PAD with FotoSan, and conventional endodontic therapy in the treatment of infected root canals. Materials and methods: The study involved 36 teeth of patients who are diagnosed with pulp necrosis or with the periapical chronic periodontitis and require endodontic treatment and divided into two groups of 18 teeth each. The first microbiological sample was taken by placing a sterile paper point in the root canal, after endodontic access cavity preparation. All root canals are prepared by Protaper Universal rotary instruments (Maillefer Instruments SA, Ballaigues, Switzerland). In the first group, the disinfection of the root canals was made with photoactivated disinfection with FotoSan. In the second group was performed the endodontic treatment with the standard protocol of irrigation - 2.5% sodium hypochlorite solution and 17% EDTA. After that, the root canals are dried with sterile points, and a second microbiological sample is taken. Results: In all compared pairs, there was no significantly different effect regarding the number of microorganisms. Conclusions; The disinfection with NaOCl has the strongest antimicrobial effect in this study. Second place is occupied by PAD with FotoSan. We believe that the established antimicrobial effect of PAD make the method appropriate as complementary to routine endodontic treatment.
